Full textAbstract:
Active physical exercises are associated with high body mineral demand that can cause mineral disbalances with diverse negative health outcomes. The purpose of this study is to examine the impact of sport - related factors on mineral composition in young ath letes. Saliva and hair samples were chosen for the analysis as reflecting immediate and more permanent mineral status, respectively. The samples were analyzed by spectral methods with inductively coupled plasma for eight essential minerals: calcium (Ca), c hromium (Cr), iron (Fe), potassium (K), magnesium (Mg), selenium (Se), and zinc (Zn). The results from athletes were compared to ones from the control group of adolescent non - athletes. Different minerals demonstrated sampling specific distribution. Sport t ype specificity of mineral content was found. These findings can help in the process of mineral status data standardization and in training process to correct the sport - associated mineral disbalances.

Full textAbstract:
Beverages are an integral part of human nutrition, yet little is known about their contribution to daily intakes of minerals and trace elements in German consumers. Using inductively coupled plasma-mass spectrometry, we determined the concentration of five minerals and six trace elements in beverage samples (n = 990, assigned to different beverage groups) collected throughout Germany. For a calculation of their relative contribution to the mineral supply, available beverage consumption data was combined with our quantitative analysis to calculate the average contribution of beverage groups to meet the respective dietary reference values currently used in Germany, Austria and Switzerland (D-A-CH region). Based on their presence in beverages and their consumption, the top three minerals are phosphorous, calcium and magnesium, and they, therefore, may reasonably contribute to the reference values. Among the trace elements, beverages mostly contributed to the manganese supply, whereas at the same time, concentrations of iron, cobalt and copper were low across all tested groups. Our study provides an overview of the assumed mineral and trace element intake via beverages in Germany and may, thus, serve as a foundation for a mineral and trace element database of beverages that needs to be expanded in the future.

Full textAbstract:
Many analytical techniques for trace element analysis are available to the geochemist and geometallurgist to understand and, ideally, quantify the distribution of trace and minor components in a mineral deposit. Bulk trace element data are useful, but do not provide information regarding specific host minerals—or lack thereof, in cases of surface adherence or fracture fill—for each element. The CAMECA nanoscale secondary ion mass spectrometer (nanoSIMS) 50 and 50L instruments feature ultra-low minimum detection limits (to parts-per-billion) and sub-micron spatial resolution, a combination not found in any other analytical platform. Using ore and copper concentrate samples from the Olympic Dam mining-processing operation, South Australia, we demonstrate the application of nanoSIMS to understand the mineralogical distribution of potential by-product and detrimental elements. Results show previously undetected mineral host assemblages and elemental associations, providing geochemists with insight into mineral formation and elemental remobilization—and metallurgists with critical information necessary for optimizing ore processing techniques. Gold and Te may be seen associated with brannerite, and Ag prefers chalcocite over bornite. Rare earth elements may be found in trace quantities in fluorapatite and fluorite, which may report to final concentrates as entrained liberated or gangue-sulfide composite particles. Selenium, As, and Te reside in sulfides, commonly in association with Pb, Bi, Ag, and Au. Radionuclide daughters of the 238U decay chain may be located using nanoSIMS, providing critical information on these trace components that is unavailable using other microanalytical techniques. These radionuclides are observed in many minerals but seem particularly enriched in uranium minerals, some phosphates and sulfates, and within high surface area minerals. The nanoSIMS has proven a valuable tool in determining the spatial distribution of trace elements and isotopes in fine-grained copper ore, providing researchers with crucial evidence needed to answer questions of ore formation, ore alteration, and ore processing.

Research subject. This articles presents the data obtained in the course of 75 analytical studies on a wide range of minerals (amphiboles, pyroxenes, garnets, spinels, olivines, anorthites, corundums, epidotes, apatites, clinochlore, dolomite, calcite, zircon) contained in igneous and metamorphic Southern Urals rocks. In addition, information is provided about the content of trace elements, including rare earth (REE) ones, in these rocks. The data on the content of trace elements in some minerals are presented for the first time (höegbomite, sapphirine, zoisite, clinozoisite, gedrite, cummingtonite, anthophyllite, potassium-magnesiohastingsite). Materials and methods. A petrographic analysis of rocks containing the minerals under study was carried out. A particular attention was paid to petrographic analysis of rocks containing the minerals under study was carried out. A particular attention was paid to “fresh” rocks, containing the mineral under study which rarely occur in the Urals. These rocks feature inclusions of serpentinite melange in the form of plates and lenses among the metamorphic strata (schists, gneisses, and amphibolites) and are characterized by the preservation of primary structures, relative chemical homogeneity, as well as the presence of simultaneous growth surfaces between most minerals. Of particular research interest were minerals from rocks, the composition of which had been relatively poorly studied (pyroxene-amphibole anorthite gabbro and gabbro-amphibolites, scapolite rocks, hornblendite, gedrite-cummingtonite-anthophyllitic crystallo-schists and amphibolites, ore-less carbonatites). The composition of mineral samples was determined using a scanning microscope REMMA-202 M equipped with an energy dispersive console and a mass-spectrometer Agilent 7700x (ICP-MS and LA-ICP-MS methods). Results. Petrographic characteristics of the rocks containing the minerals under study are given. The geographical coordinates of locations, where mineral sampling was performed, are provided. The content of trace elements is shown to vary greatly within related species of minerals (amphiboles, garnets, pyroxenes, olivines, epidotes, spinels, mica, etc.), with the fluctuations being independent of the alkalinity of host rocks or their geological nature.Conclusions. For the first time, a significant role of zoisite and clinozoisite in the process of concentrating trace elements, including REE, has been revealed. The role of apatite as one of the main mineral concentrators of REE has not been confirmed either in the main and ultrabasic rocks, or in some calcite-dolomite carbonatites.

The accurate measurement of low levels of trace elements is now necessary in most petrological studies. In this paper, we present the methods used in our laboratory ("Collectif interinstitutionnel de géochimie instrumentale") to analyse simultaneously, with the ICP-MS instrument, 26 trace elements in silicate rocks and minerals. Whole-rocks are prepared using a lithium metaborate fusion in order to assure dissolution of resistant mineral phases, whereas mineral separates (plagioclases, pyroxenes, apatites) are prepared using an open acid digestion. Calibration of the ICP-MS is made with international reference materials for whole-rocks and with synthetic aqueous solutions for mineral separates. The accuracy of the data as well as limits of quantification (LOQ) vary among elements but are usually very good (accuracy better than 6%, LOQ usually below 1 microg/g in solids). Combination of XRF and ICP-MS capabilities enables us to determine 38 elements (major and trace) on a routine basis.

Full textAbstract:
Seaweeds have been used since ancient times as food, food additives, fertilizer, and a source of medicine. Like terrestrial plants, seaweeds contain many inorganic and organic substances which can beneficial to human health. Seaweeds have great potential as “bioactive compounds for functional use, “algae mineral supplements”, “pharmaceuticals and cosmetics” and in addition to their potential of good sources of minerals, trace elements, proteins, lipids, and carbohydrates as traditional food. Due to the mineral absorption ability of macroalgae from the seawater, many species are a perfect source of some trace elements such as iron and iodine and a good source of some macro minerals such as calcium, phosphate, and magnesium. In some cases, the mineral content of the seaweeds may be higher than that of land plants. Scientific data show that the bioavailability of algae minerals is higher than rock-based minerals for humans. In recent years, the potential use of seaweed minerals as “algae mineral supplements” gained attention due to their rich elemental composition and the importance of minerals for human health. Mineral composition of seaweeds may vary according to locality, season, residence time, species physiology, and environmental conditions such as level of elements in seawater, light intensity, and salinity. Thus, new approaches and researches are needed on how much seaweeds can be consumed daily and their potential health risks. In this study, the mineral contents of seaweeds, the importance of minerals for human health, and potential uses of algae minerals were investigated.

Sheep were fed an oaten hayllupin mixture (88: 12 W/W) containing either 0, 1.7, 3.3, 6.3, 12 or 21% of a multi-element mineral mix for 6 months. Each sheep was fed sufficient ration to provide 800 g DM of the oaten hay/lupin mixture per day. The accumulation of essential and of potentially toxic elements in the tissues of the sheep was measured together with feed intake and growth. Some sheep which were offered 12% and all of the sheep which were offered 21% minerals in the diet refused to eat part or all of the ration and were removed from the experiment. All sheep in the other groups and two sheep which were fed 12% minerals ate all or most of the ration for 6 months. All sheep in the groups which were fed 0, 1.7, 3.3 and 6.3% (equivalent to 0, 15, 30 and 60 g/day of minerals) grew at 27-35 g/day and had similar dry matter intakes after intake of minerals was excluded from the calculation. The two sheep which were fed 12% mineral throughout (equivalent to 120 g/day) lost 6 g/day during the experiment. Intake of minerals increased selenium concentrations in whole blood and liver, and vitamin B12 in plasma. Selenium did not accumulate to levels that resulted in toxicity to the sheep nor exceed maximum permitted levels for human consumption. Fluorine in rib bone increased as mineral intake increased, and sheep which were fed 12% minerals in the diet were at risk of chronic fluorosis. The intake of mineral mix had no significant effect on the concentrations of copper and iron in the liver or the concentration of cadmium in the kidney.

Full textAbstract:
AbstractProcesses of mineral alteration involving the mobilization and deposition of more than 30 chemical elements during bauxite formation and epigenesis have been studied on specimens from the Devonian Schugorsk bauxite deposit, Timan, Russia. Chemical analyses of the minerals were obtained by electron microprobe and element distribution in the minerals was studied by element mapping. Interpretation of these data also utilized high-resolution BSE and SE images.The main rock-forming minerals of the Vendian parent rock are calcite, dolomite, feldspar, aegirine, riebeckite, mica, chlorite and quartz; accessory minerals are pyrite, galena, apatite, ilmenite, monazite, xenotime, zircon, columbite, pyrochlore, chromite, bastnaesite and some others. Typically, the grainsize of the accessory minerals in both parent rock and bauxite is from 1 to 40 µm. However, even within these rather small grains, the processes of crystal growth and alteration during weathering can be determined from the zonal distribution of the elements. The most widespread processes observed are: (1) Decomposition of Ti-bearing minerals such as ilmenite, aegirine and riebeckite with the formation of ‘leucoxene’, which is the main concentrator of Nb, Cr, V and W. Crystal growth can be traced from the zonal distribution of Nb (up to 16 wt.%). Vein-like ‘leucoxene’ is also observed in association with organics. (2) Weathering of columbite and pyrochlore: the source of Nb in ‘leucoxene’ is now strongly weathered columbite, while the alteration of pyrochlore is expressed in the growth of plumbopyrochlore rims around Ca-rich cores. (3) Dissolution of sulphide minerals and apatite and the formation of crandallite group minerals: ‘crandallite’ crystals of up to 40 µm size show a very clear zonation. From the core to the rim of a crystal, the following sequence of elements is observed: Ca → Ba → Ce → Pb → Sr → Nd. Sulphur also shows a zoned but more complicated distribution, while the distribution of Fe is rather variable. A possible source of REE is bastnaesite from the parent rock. More than twelve crandallite type cells can be identified in a single ‘crandallite’ grain. (4) Alteration of stoichiometric zircon and xenotime with the formation of metamict solid solution of zircon and xenotime: altered zircon rims also bear large amounts of Sc (up to 3.5 wt.%), Fe, Ca and Al in the form of as yet unidentified inclusions of 1–2 µm. Monazite seems to be the least altered mineral of the profile.In the parent rock, an unknown mineral of the composition (wt.%): ThO2 – 54.8; FeO – 14.6; Y2O5 – 2.3; CaO – 2.0; REE – 1.8; SiO2 12.2; P2O5 – 2.8; total – 94.2 (average from ten analyses) was determined. In bauxite, another mineral was found, which has the composition (wt.%): ThO2 – 24.9; FeO – 20.5; Y2O5 – 6.7; CaO 2.0; – ZrO – 17.6; SiO2 – 8.8; P2O5 – 5.4; total – 89.3 (F was not analysed; average from nine analyses). Presumably, the second mineral is the result of weathering of the first one. Although the Th content is very high, the mineral is almost free of Pb. However, intergrowths of galena and pyrite are observed around the partially decomposed crystals of the mineral. Another generation of galena is enriched in chalcophile elements such as Cu, Cd, Bi etc., and is related to epigenetic alteration of the profile, as are secondary apatite and muscovite.

This study was conducted to investigate the effects of different patterns and sources of Zn, Fe, Cu, Mn, and Se on performance, mineral deposition (liver, kidney, pancreas, spleen, pectorals muscle, and tibia), and excretion of laying hens, then to find an optimal dietary supplemental pattern of trace elements in laying hens. A total of 864 healthy laying hens with similar laying rate (Roman, 26-week-old) were randomly divided into nine treatments, with six replications of 16 birds per replication, including a control treatment and four patterns with different element sources (inorganic or organic): (1) Control treatment (basic diet without added extra trace minerals, CT); pattern 1, NRC (1994) recommended level (NRC-L): (2) inorganic minerals of NRC-L pattern (IN), (3) organic minerals of NRC-L pattern (ON); pattern 2, NY/T 33-2004 recommended level (NY/T-L): (4) inorganic minerals of NY/T-L pattern (IY), (5) organic minerals of NY/T-L pattern (OY); pattern 3, 50% NRC (1994) recommended level (50% NRC-L): (6) inorganic minerals of 50% NRC-L pattern (IHN), (7) organic minerals of 50% NRC-L pattern (OHN); pattern 4, the ratio of minerals in blood of laying hens was taken as the supplement proportion of trace elements, and Zn was supplemented depended on NRC recommended level (TLB): (8) inorganic minerals of TLB pattern (IB), (9) organic minerals of TLB pattern (OB). Two weeks were allowed for adjustment to the conditions and then measurements were made over eight weeks. Supplementation of trace elements led to increased daily egg weight (p < 0.05). Patterns of minerals in diets affected the content of liver Mn, pancreas Mn, tibia Mn, and the tissues Se (p < 0.05). Sources of minerals had positive effects on daily egg weight (p < 0.05), the concentrations of liver Fe, kidney Cu, tissues Se (except spleen), and fecal Se (p < 0.05). In conclusion, diet supplemented with the organic trace minerals of 50% NRC-L pattern (OHN) in laying hens promoted optimum laying performance, mineral deposition, and reduced mineral excretion.

Minerals and trace elements in cow's milk occur as inorganic ions and salts or form complexes with proteins and peptides, carbohydrates, fats and small molecules. The main mineral binder or chelators of calcium are the caseins, αs1-casein, αs2-casein, β-casein and κ-casein, but also whey proteins and lactoferrin bind specific minerals like calcium, magnesium, zinc, iron, sodium and potassium. Less documented is the binding of trace elements. Peptides obtained byin vitroorin vivohydrolysis act as mineral trappers through specific and non-specific binding sites. They may then function as carriers, chelators, of various minerals and thus enhance or inhibit bioavailability. Peptides from milk proteins have found interesting new applications in the food industry as products with improved functionality or as ingredients of dietary products, or used in pharmaceutical industry. Fortification of foods with minerals in a low concentration has for a long time been used in some countries to overcome mineral deficiency, which is an increasing problem in humans. These types of foods are being used to create a new generation of super foods in the industry today.

The present work determined complete mineral profile of four different types of grains (spelt, soybean, maize, and buckwheat) grown under two growing systems – conventional and organic. The contents of 20 macro-, micro- and trace elements were analysed in the examined grains by inductively coupled plasma-optical emission spectrometry (ICP-OES). In most samples, nine elements were present in concentrations higher than 10 mg/kg. The remaining elements were present at lower concentrations or in traces or not detected in certain samples. Aluminium and arsenic, as two toxic elements, were detected only in organic buckwheat grains. Based on the obtained results for the mineral contents, a nutritive assessment of the quality of grains of spelt, soybean, maize, and buckwheat were made. Results of nutritional assessment showed that spelt, soybean, and buckwheat grains could potentially be good sources of several minerals for human diet. On the other hand, the presence of some toxic elements, such as cadmium and strontium, should be monitored. Results of principal component analysis (PCA) and hierarchical cluster analysis (HCA) shown that the mineral composition, to a much greater extent, depended on the botanical origin of grains as compared to the production system.

This is the first attempt to provide a general mineralogical and geochemical survey of natural Ca2SiO4-bearing combustion metamorphic (CM) rocks produced by annealing and decarbonation of bioproductive Maastrichtian oil shales in the Hatrurim Basin (Negev Desert, Israel). We present a synthesis of data collected for fifteen years on thirty nine minerals existing as fairly large grains suitable for analytical examination. The Hatrurim Ca2SiO4-bearing CM rocks, which are natural analogs of industrial cement clinker, have been studied comprehensively, with a focus on several key issues: major- and trace-element compositions of the rocks and their sedimentary precursors; mineral chemistry of rock-forming phases; accessory mineralogy; incorporation of heavy metals and other trace elements into different phases of clinker-like natural assemblages; role of trace elements in stabilization/destabilization of Ca2SiO4 polymorphic modifications; mineralogical diversity of Ca2SiO4-bearing CM rocks and trace element partitioning during high-temperature–low-pressure anhydrous sintering. The reported results have implications for mineral formation and element partitioning during high-temperature–low-pressure combustion metamorphism of trace element-loaded bituminous marine chalky sediments (“oil shales”) as well as for the joint effect of multiple elements on the properties and hydration behavior of crystalline phases in industrial cement clinkers.

Full textAbstract:
This study evaluates the differences in mineral and toxic trace element concentrations of Nile tilapia (Oreochromis niloticus) tissues from three aquatic ecosystems in Ethiopia—Lake Ziway, Lake Langano, and Gilgel Gibe reservoir—with a focus on edible (fillet) and discarded (digestive tract, gills, skin, and liver) parts. A total of sixty (n = 60) Nile tilapia samples were collected, comprising twenty (n = 20) fish from each lake, and analyzed by inductively coupled plasma mass spectrometry. All elements varied markedly among tissues and between the lakes. Some differences in element concentrations were attributed to differences in nutrient load in the ecosystems and the function of the tissues. For instance, the calcium concentrations in skin and gill were distinctly higher in fish from calcium-rich Lake Langano. The d iscarded parts were richer in essential trace elements, showing an opportunity to promote their use in human nutrition to increase the intake of important minerals. However, the accumulation of elements toxic to humans, such as aluminum, should be monitored and, in particular, controlled when rearing these fish in aquaculture.

Abstract Trace elements selenium, copper, and zinc are essential minerals for the human body. One of the means to increase the micronutrient content in diets is to add them to food raw materials, for example, to enrich grain with micronutrients during malt production. To obtain rye malt, 3 kg grain was soaked in 10 l water with addition of three mineral salts — sodium selenate (Na2SeO4), copper sulphate (CuSO4 5H2O), and zinc sulphate (ZnSO4 7H2O) at different concentrations and different combination of salts. The concentration of selenium, copper, and zinc was determined in rye malt. The obtained results were used to calculate the degree of assimilation of trace elements in rye malt. The interaction of trace elements selenium/copper and copper/zinc was studied. The total amount of selenium, copper, and zinc was analysed by inductively coupled plasma mass spectrometry (ICP-MS). Sample preparation for elemental analysis was performed by wet acid digestion in a closed microwave mineralisation system. The selenium assimilation degree in rye malt was within 10.6 to 12.2%. Accordingly, copper assimilation was 32.8 to 38.0% and zinc 49.3 to 57.0%. Simultaneous presence of selenium/copper and copper/zinc during rye grain soaking promoted the assimilation of each mineral, compared with only one mineral additive.

The results of studies to determine the optimal level of input of a complex of macronutrients in protein-vitamin-mineral supplements are given, their influence on digestibility, the use of feed nutrients, hematological parameters, growth and development of young pigs are studied. Feeding in the composition of grain-cereal rations of 12.5% protein-vitamin-mineral supplements with elevated levels of Fe, Cu, Zn, Mn, Co, J, Se contributes to an increase in pigs by 5.5-8.5% of daily gains, by 8-12 days of early maturity, by 0.28-3.35% slaughter yield, by 12.1-19.5% meat ratio. Bringing microelements to the optimum level in protein-vitamin-mineral supplements composition contributes to a significant increase in the digestibility of organic matter and raw fat. Reducing the level of trace elements by 30% hinders the process of digestion of feed. The use of 12.5% protein-vitamin-mineral supplements with a high content of trace elements in grain-cereal rations of pigs has a significant effect on the degree of utilization of nitrogen, calcium, phosphorus, iron, copper, zinc, manganese. When protein-vitamin-mineral supplements are fed with an optimal level of trace elements in the composition of diets of young pigs, it contributes to an increase in the number of erythrocytes, hemoglobin, total protein and its fractions. A 30% increase in the level of trace elements in protein-vitamin-mineral supplements provides for obtaining high-energy meat with a high content of dry matter, protein and fat. The inclusion in the composition of grain-cereal rations of protein-vitamin-mineral supplements with the optimal level of trace elements helps to reduce the cost of feed by 5.2-7.8%, to obtain 3.8 kg of additional growth.

Full textAbstract:
In the complete feeding of animals, including pigs, an important role is given to mineral elements, because they take an active part in the metabolism, provide normal conditions for the work of all internal organs, muscles and nervous system. Mineral elements are used by the body of animals as a structural material, they participate in the enzymatic processes of digestion, absorption, synthesis, decomposition, as well as the allocation of metabolic products from the body. Minerals have a positive effect on the activity of enzymes, hormones, vitamins, stabilize acid-alkaline balance and osmotic pressure. They affect the function of hematopoiesis, endocrine glands, protective reactions of the organism, microflora of the digestive tract, participate in protein biosynthesis, strengthen the permeability of cell membranes, etc. The absence or lack of individual mineral elements, as well as the violation of their ratio leads to a reduction in the efficiency of nutrient utilization in the diet and, consequently, to reduce the productivity of animals. Mineral substances account for 4–5% of the body weight of animals, of which 99.6% are on macro-elements, and 0.4% of trace elements. The main source of mineral elements for animals is feed. However, the mineral composition of the latter depends on the biogeochemical zone, type of soils, climatic conditions, plant species, agrochemical measures, collection, storage, preparation for feeding and other factors. When using copper in the form of chelates, a high coefficient of its assimilation is established. In blood, the serum iron content of iron increased and this contributed to a decrease in total and latent iron binding capacity of serum. Copper chelates more intensively stimulate protein synthesizing function, which manifests itself by increasing the content of total protein, albumin and reducing the amount of globulins. Application of micronutrients and their chelate compounds and other biologically active substances has its advantages, the level of assimilation of heavy metals, radionuclides from contaminated feeds and water is reduced, chelate complexes of trace elements easily penetrate through cell membranes, allowing to carry out purposeful influence on exchange substances and energy and to correct the deficit of TE in the relevant biogeochemical zones.

Full textAbstract:
The issues of trace element emissions during coal combustion has been a concern in recent years due to their environmental pollutant. To study the trace element transformation, the thermodynamic calculation (FactSage 7.2) was used. Five kinds of pure mineral oxides (Al2O3, CaO, Fe2O3, K2O, and MgO) and As, B, Cr, F, and Se in fly ash were considered for trace elements. The results confirm that all mineral oxides have a good correlation with arsenic to form Ca3(AsO4)2, FeAsO4, K3AsO4, and Mg3(AsO4)2. Boron has a good relationship with Al, Ca, and Mg to form (Al2O3)9(B2O3)2, Ca3B2O6, and Mg3B2O6. Chromium has a good correlation with K and Ca to form K2CrO4, CaCr2O4. Furthermore, FeF3(s) KF(s), and AlF3(s) are predicted from the interaction of fluorine with Fe2O3, K2O, and Al2O3. The effect of mineral oxides on selenium partitioning are not observed. The inhibition order of trace elements by mineral oxides is as follow: As (Al2O3 > MgO > CaO > Fe2O3 > K2O), B (Al2O3, CaO, Fe2O3, K2O, > MgO), Cr (CaO > K2O > Al2O3, MgO, Fe2O3), F (CaO > MgO > Al2O3 > Fe2O3 > K2O). The results will be useful to control the trace element emissions.

Walnuts (Juglans nigra) are considered to be a functional food. In the present study, twenty one macro-, micro-, and trace elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Se, Sr, and Zn) were selected to be determined in walnuts and walnut oils. The beneficial content of essential elements could be shown by the obtained results, the macro-elements Ca, K, Mg, and Na being present in nuts with 1062 mg/kg, 2771 mg/kg, 1426 mg/kg, and 42.3 mg/kg, respectively. Regarding micro- and trace elements, the following order (decreasing content) was found: Mn > Fe > Zn > B, Mo > Cu > Ni > Co > Al > Sr > Ba > Li > Pb > Se > Cr > As > Cd. Furthermore, the potentially toxic trace elements (As, Cd, Pb) determined were below the maximum allowed values in most of the investigated walnut samples. A comparison of oils and nuts revealed that the former contain lower concentrations of all elements analyzed except for Fe and Zn. This suggested the origin from contamination during oil processing. Fe influences the oil oxidation rate, thus its entry during production should be avoided.

Mineral composition and content analysis of selected trace elements (Ag, As, Ba, Be, Br, Cd, Ce, Co, Cr, Cs, Cu, Ga, I, La, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sn, Sr, Ti, Tl, U, V, and Zn; 308 rock samples) were studied in the Upper Permian (Zechstein) potash-bearing deposits in Poland. They represented K–Mg chlorides of PZ2 and PZ3 cyclothems from four salt domes and stratiform K–Mg sulphates of PZ1 cyclothem. The dominant mineral components of K–Mg sulphates (polyhalite) are anhydrite and polyhalite. The most common minerals of the K–Mg salts of PZ2 cyclothem are halite, sylvite, kieserite, and anhydrite, and the most common of PZ3 cyclothem are halite, carnallite, kieserite, and anhydrite. Most analysed trace elements in the Zechstein potash-bearing deposits show a low content (up to 26 mg/kg) that eliminates them as potential profitable source rocks of such required elements as Ce, Cs, La, Li, or Rb. Common elements, such as Br, Fe, and Sr, are more easily exploited from natural brines, sulphate, and ore deposits.

The present study was undertaken to determine the content of six minerals, five trace elements, and ten pesticide residues in honeys originating from different regions of Malaysia. Calcium (Ca), magnesium (Mg), iron (Fe), and zinc (Zn) were analyzed by flame atomic absorption spectrometry (FAAS), while sodium (Na) and potassium (K) were analyzed by flame emission spectrometry (FAES). Trace elements such as arsenic (As), lead (Pb), cadmium (Cd), copper (Cu), and cobalt (Co) were analyzed by graphite furnace atomic absorption spectrometry (GFAAS) following the microwave digestion of honey. High mineral contents were observed in the investigated honeys with K, Na, Ca, and Fe being the most abundant elements (mean concentrations of 1349.34, 236.80, 183.67, and 162.31 mg/kg, resp.). The concentrations of the trace elements were within the recommended limits, indicating that the honeys were of good quality. Principal component analysis reveals good discrimination between the different honey samples. The pesticide analysis for the presence of organophosphorus and carbamates was performed by high performance liquid chromatography (HPLC). No pesticide residues were detected in any of the investigated honey samples, indicating that the honeys were pure. Our study reveals that Malaysian honeys are rich sources of minerals with trace elements present within permissible limits and that they are free from pesticide contamination.

Full textAbstract:
Traditional farmers’ varieties of tomato grown under extensive farming techniques are considered delicious and healthy foods and are preferred by local consumers. Tomatoes are an important component of a healthy diet, as they provide essential micronutrients, including minerals, which are vital to healthy development, disease prevention, and wellbeing. Given the considerable dietary intake of tomatoes and the scarcity of information about the bioaccessibility of inorganic constituents in this fruit, this study was carried out to evaluate the content and bioaccessibility of minerals (macro- and microelements) in tomato farmers’ varieties widely cultivated in northeastern Portugal homegardens. Among the macroelements, K stood out as the most abundant mineral in the studied varieties, followed by Mg, Ca, and Na. Regarding the microelements, while the yellow tomato had higher concentrations of Fe and Cu, the round tomato had more Zn and Mn. The in vitro bioaccessibility assessment showed that, among the macroelements, Mg was more bioaccessible than Ca and K when all the tomato varieties were considered together. Among the microelements, Cu seemed to be the most bioaccessible. Although the contribution of a 100 g serving of the studied tomato farmers’ varieties to the dietary reference intakes (DRIs) of minerals is relatively low, this food could contribute to reaching these mineral requirements, as it is included in the diet of most of the population, especially in Mediterranean regions.

Full textAbstract:
Whiteleg shrimp (Litopenaeus vannamei) is now the main species cultivated in various geographic locations. Whiteleg shrimp have a wide range of salinity tolerance, but a matter of deficiency of minerals and trace elements need to be taken care of when shrimp are grown in low saline area. It may induce higher mortality and slower growth performances of shrimp. Two stages of shrimp juveniles were subsequently tested with different formulae of a liquid nutraceutical of essential minerals and trace elements. Each stage was performed in a 28-day trial with follow-up parameters of shrimp growth indices and environmental changes throughout the tests. The use of mineral supplementation in whiteleg shrimp diet in low salinity area significantly increased growth performance, survival rate and color intensity. This study has demonstrated the efficacy of a liquid form of mineral supplement product administered by top-coating onto the feed to shrimp during 4 weeks of grow-out at 5‰ salinity, but the application was dependent on formula and dose. Further research on application regime using this liquid mineral product should be performed to optimize a protocol for a whole culture crop as different stages of shrimp may require different supplementation doses.

Full textAbstract:
This study presents an evaluation of arsenic and other trace metals in the Hrazdan Iron-Ore project in Armenia using a methodology typically associated with Geometallurgical characterization. The principal host of the trace elements is pyrite and oxidized equivalents. Pyrite is a mineral of elemental concern as it has the potential to generate acidic pH in water that it contacts and thus mobilize metals of concern. In the Hrazdan deposit, there is a general excess of neutralizing carbonate minerals that result in adequate buffering of generated acid and limiting the mobility of metal cations in solution. However, metalloids that form oxyanions species such as those of arsenic or chromium tend to be more mobile in neutral to alkaline mine drainage. From the geometallurgical assessment of the mine waste, the results of the geochemical testwork can be explained and the information used to assess potential issues with mine waste storage, timing of metal release and provide a baseline for mitigation strategies.

Bone is a dynamic tissue with a quarter of the trabecular and a fifth of the cortical bone being replaced continuously each year in a complex process that continues throughout an individual’s lifetime. Bone has an important role in homeostasis of minerals with non-stoichiometric hydroxyapatite bone mineral forming the inorganic phase of bone. Due to its crystal structure and chemistry, hydroxyapatite (HA) and related apatites have a remarkable ability to bind molecules. This review article describes the accretion of trace elements in bone mineral giving a historical perspective. Implanted HA particles of synthetic origin have proved to be an efficient recruiting moiety for systemically circulating drugs which can locally biomodulate the material and lead to a therapeutic effect. Bone mineral and apatite however also act as a waste dump for trace elements and drugs, which significantly affects the environment and human health.

AbstractData on the distribution of the precious metals (Au, Ag and the platinum=group elements Ru, Rh, Pd, Os, Ir, Pt) are rapidly accumulating as a consequence of the application of microbeam analytical techniques such as the electron microprobe, the proton microprobe, and the ion microprobe. The new data obtained with these techniques build on knowledge accumulated over the last 140 years using bulk analytical methods (e.g. spectrographic). The nature of the occurrence, the concentrations, and the variation in amount s of precious metals in minerals and mineral products are reviewed with comments as to the significance of the results with respect to industrial and environmental concerns. Future directions in mineral-specific analysis of trace precious-metal concentrations and applications outside of process mineralogy are discussed.

Abstract The objective of the present study was to investigate selected trace and mineral elements in Royal Jelly (RJ) from Bulgaria. A total of 30 RJ samples were included in the study. The analytical procedure consisted of the microwave digestion of the RJ samples with nitric acid followed by instrumental measurement. Concentrations of Al, Ba, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, P, Sr and Zn were determined using inductively coupled plasma optical emission spectroscopy (ICP-OES), while As, Cd, Co, Ni and Pb were determined by electrothermal atomic absorption spectrometry (ETAAS). Our results showed that elements K, Mg, Ca represented 96% from the total mineral content of the RJ samples from Bulgaria, while the most abundant trace element was Na, followed by Zn. The elements Ba, Cr, Cu, Fe, Mn and Sr were found in trace concentration levels and elements As, Pb, Cd, Co and Ni in microconcentration levels. Selected mineral and trace elements were found in relatively constant concentration levels in all of the analyzed RJ samples. It was concluded that chemical element content did not depend on geographical origin and was under homeostatic adjustment in RJs.

Medicinal plants enhanced with minerals are tested to determine whether these elements could be used as a new source of mineral dietary supplements that provide essential minerals in a more available form than current, inorganically based mineral supplements. The tribe Kanikaran or Kani of Agasthiar Hills has the sound knowledge on medicinal plants, which leads to the present investigation on the five selected plants, Amorphophallus paeonifoliius (Areaceae), Phyllanthus polyphyllus Willd (Euphorbiaceae), Fluggea leucopyrus (Euphorbiaceae), Stephania wightii Dunn (Menispermaceae) and Ventilago Madaraspatana (Rhamaceae). The Calcium content is high in Ventilago Madaraspatana, Iron content is more in Amorphophallus paeoniifolius, Manganease value is higher in Phyllanthus polyphyllus, and the values of potassium, Sodium, Barium, Copper,and Zinc are higher in Stephania wightii Dunn. The present study shows that Stephania wightii Dunn root is highly nutritive. This study can bring out many different clues for the development drugs to treat human diseases.

This study has been carried out in order to determine the effect of increasingly intensive fertilization with potassium, applied in combination with nitrogen, on the content of trace elements in soil after the harvest of maize (Zea mays L.). The soil content of trace elements depended on the fertilization with potassium and nitrogen. Potassium fertilization had a stronger effect on the content of trace elements in the pots fertilized with the lower nitrogen dose (130 mg N kg−1 of soil). The increasing doses of potassium led to a higher soil content of zinc (Zn), and especially of nickel (Ni). The impact of potassium fertilization on the content of the remaining trace elements in the soil was less unambiguous, and depended on the dose of potassium and nitrogen fertilization. Nitrogen fertilization resulted in a higher soil content of manganese (Mn), chromium (Cr), nickel (Ni) and cadmium (Cd), as well as a decreased soil content of lead (Pb). It needs to be underlined that changes in the soil content of Ni, Cd, and Pb, effected by nitrogen fertilization, were larger than in the cases of the other trace elements. The influence of potassium and nitrogen fertilization did not result in exceeding the current threshold amounts of trace elements set for agriculturally used soil. An increase in the contents of some trace elements in soil is beneficial from an agricultural point of view. Some of these elements are necessary for the correct growth and development of arable plants.

Full textAbstract:
Background: Minerals and trace element content of human milk have been a matter of concern among nutritionist in relation to the availability of the essential elements to the new born. Mineral and trace elements occur in the body in a number of chemical forms, such as inorganic ions and salts, or as constituents of organic molecules, for example proteins, fats, carbohydrates and nucleic acids. There is a paucity of data on the effect of nutrition on the composition of trace elements in milk and its effect on the infant. Hence a comparison made between the trace element and mineral such as sodium, potassium, magnesium, iron, zinc, copper, calcium in milk of malnourished and well-nourished mothers in order to determine the effect of maternal nutrition on the quality of milk and its effect on the growth and physical development of the new-born.Methods: Around 100 mothers were enrolled in the study after obtaining prior informed consent. They were divided into 2 groups-group I had 50 malnourished mothers and group II had 50 well-nourished mothers. The pre-fed milk sample which was collected was stored at - 20℃ until it was processed. It was thawed and analysed for copper, zinc, iron, magnesium, sodium, potassium and calcium.Results: The mean levels of trace elements (iron and zinc) and minerals (sodium, potassium, calcium, magnesium) were slightly more among well-nourished than malnourished women. Values of only copper were significantly higher in the colostrum of well-nourished as compared to that of the malnourished mothers.Conclusions: The parameters of weight, height weight/height ratio and hemoglobin varied significantly between the well-nourished and malnourished mothers. The difference in milk content of malnourished and well-nourished mothers is not significant for sodium, potassium, calcium, iron, magnesium, zinc. However, copper levels were significantly higher in well-nourished mothers.

Abstract The minerals and trace elements that account for about 4% of total human body mass serve as materials and regulators in numerous biological activities in body structure building. Infant formula and milk products are important sources of endogenic and added minerals and trace elements and hence, must comply with regulatory as well as nutritional and safety requirements. In addition, reliable analytical data are necessary to support product content and innovation, health claims, or declaration and specific safety issues. Adequate analytical platforms and methods must be implemented to demonstrate both the compliance and safety assessment of all declared and regulated minerals and trace elements, especially trace-element contaminant surveillance. The first part of this paper presents general information on the mineral composition of infant formula and milk products and their regulatory status. In the second part, a survey describes the main techniques and related current official methods determining minerals and trace elements in infant formula and milk products applied for by various international organizations (AOAC INTERNATIONAL, the International Organization for Standardization, the International Dairy Federation, and the European Committe for Standardization). The third part summarizes method officialization activities by Stakeholder Panels on Infant Formula and Adult Nutritionals and Stakeholder Panel on Strategic Food Analytical Methods. The final part covers a general discussion focusing on analytical gaps and future trends in inorganic analysis that have been applied for in infant formula and milk-based products.

The effect of five mineral nutrients on the variability of the content of biochemical compounds, such as flavonoids, phenolic compounds, vitamin C, carotenoids and the antioxidant activity of kale (Brassica Oleracea var. sabellica) collected at the edible maturity stage. Manipulation of the phytochemical composition of the kale cabbage using mineral fertilizers was evident in the results achieved. The various mineral nutrients used had different effects on the content of the studied phytochemicals. The content of flavonoids and carotenoids did not decrease with any of the various mineral nutrients used. Contrary to recent research suggesting that rare earth elements are good stimulators of secondary metabolite accumulation, our results showed a decrease in the content of phenolic compounds in plants fertilized with neodymium. The total antioxidant activity increased under the influence of NPK and humate, which correlated with the highest content of soluble phenolic compounds and flavonoids in kale leaves. Low doses of N have a positive effect on these indicators. Mineral supplements of trace elements also had a stimulating effect on the accumulation of the studied substances. However, in addition to trace elements, a significant role is played by the presence of humic acids (in humate), which together with trace elements have the maximum stimulating effect on the content of the substances under study.

It is generally believed that breast-fed infants absorb adequate quantities of minerals and trace elements, whereas there is some concern about how well infants can utilize these nutrients from cow's milk formula and other infant diets. Therefore, most infant formulas contain much higher concentrations of minerals and trace elements than those of breast milk. Our knowledge of how infants can utilize these nutrients from different diets is very limited. This paper critically reviews the effects of various components in breast milk, cow's milk, and infant formula and how they either facilitate or inhibit the absorption of minerals and trace elements. Particular emphasis is put on milk proteins such as lactoferrin, casein, and whey proteins, but phytate in soy formula is also discussed. Competition among minerals for absorptive pathways as well as other nutrient-nutrient interactions are considered in the context of infant nutrition. The difficulties involved in assessing mineral and trace element status in infants, as well as the potential consequences of suboptimal and excessive intakes of calcium, magnesium, iron, zinc, copper, manganese, and selenium are also discussed, particularly in the light of infant requirements.

Abstract Pyrite is a common mineral in sedimentary rocks and is the major host for many chalcophile trace elements utilized as important tracers of the evolution of the ancient hydrosphere. Measurement of trace element composition of pyrite in sedimentary rocks is challenging due to fine-grain size and intergrowth with silicate matrix and other sulfide minerals. In this contribution, we describe a method for calculation of trace element composition of sedimentary pyrite from time-resolved LA-ICP-MS data. The method involves an analysis of both pyrite and pyrite-free sediment matrix, segmentation of LA-ICP-MS spectra, normalization to total, regression analysis of dependencies between the elements, and calculation of normalized composition of the mineral. Sulfur is chosen as an explanatory variable, relative to which all regressions are calculated. The S content value used for calculation of element concentrations from the regressions is calculated from the total, eliminating the need for independent constraints. The algorithm allows efficient measurement of concentrations of multiple chalcophile trace elements in pyrite in a wide range of samples, including quantification of detection limits and uncertainties while excluding operator bias. The data suggest that the main sources of uncertainties in pyrite composition are sample heterogeneity and counting statistics for elements of low abundance. The analysis of regression data of time-resolved LA-ICP-MS measurements could provide new insights into the geochemistry of the sedimentary rocks and minerals. It allows quantification of ratios of elements that do not have reference material available (such as Hg) and provides estimates on the content of non-sulfidic Fe in the silicate matrix. Regression analysis of the mixed LA-ICP-MS signal could be a powerful technique for deconvolution of phase compositions in complex multicomponent samples.

Honey is an extensively utilized sweetener containing sugars and water, together with small quantities of vitamins, minerals, fatty acids, amino acids and proteins. Naturally produced by honeybees (Apis mellifera) from floral nectar, honey is increasingly sold as a health food product due to its nutritious features. Certain honeys are retailed as premium, trendy products. Honeybees are regarded as environmental monitors, but few reports examine the impact of environment on Australian honey trace elements and minerals. In higher density urban and industrial environments, heavy metals can be common, while minerals and trace elements can have ubiquitous presence in both agricultural and urban areas. Honey hives are traditionally placed in rural and forested areas, but increasingly the trend is to keep hives in more urban areas. This study aimed to determine the levels of 26 minerals and trace elements and assess elemental differences between honeys from various regional Queensland and Australian sources. Honey samples (n = 212) were acquired from markets, shops and supermarkets in Queensland while urban honeys were purchased online. The honey samples were classified into four groups according to their regional sources: urban, rural, peri-urban and blend honey. Elemental analyses of honey were performed using ICP-MS and ICP-OES after microwave and hot block digestion. Considerable variations of essential trace elements (Co, Cu, Cr, Fe, Mn, Mo and Zn) and mineral levels (Ca, K, Mg, Na and P) were found in honeys surveyed. There were significant differences (p < 0.05) between urban and rural honey samples for B, Na, P, Mn, K, Ca and Cu. Significant differences (p < 0.05) were also found between blend and urban honey samples for K, Cu, P, Mn, Sr, Ni, B and Na. Peri-urban versus urban honeys showed significant differences in P, K and Mn. For rural and peri-urban honeys, the only significant difference (p < 0.05) was for Na. Toxic heavy metals were detected at relatively low levels in honey products. The study revealed that the Queensland/Australian honey studied is a good source of K and Zn and would constitute a good nutritional source of these elements.

Full textAbstract:
The Jugan Gold Deposit (JGD) is part of the Bau Mineral District (BMD) in Bau, Sarawak, East Malaysia. Although the mineral district is well studied, limited studies were conducted on the JGD. This paper presents the results of statistical studies using the multi-element geochemical data emphasizing the trace elements association with gold, alteration-mineralization, and the precipitation mechanism of the gold-bearing sulfide minerals. The correlation matrix displays positive correlation associations, particularly those associated with gold mineralization, i.e., arsenic, sulfur, antimony, and bismuth. Factor analysis grouped the trace elements into eight factors that reflect lithologies, mineralization, alteration, and geological processes in the JGD. Elements comprising the gold mineralization assemblage have the most significant factor (Factor 1) with the highest variance. The mineral assemblage was enriched during the alteration-mineralization process, as confirmed by the isocon plot. The barren samples (<0.01g/t) and gold-bearing samples (>0.2 g/t) plotted in a Fe vs. S diagram indicate that sulfidation is the precipitation mechanism of gold-bearing sulfide minerals. The immobility of iron and the vertical trajectory trend in the Fe vs. S diagram suggest that the possible source of Fe for gold-bearing sulfide minerals is the sedimentary host rock. Collectively, characteristics such as (1) the association of gold-bearing sulfide minerals with carbonate mineral assemblage and (2) high bismuth loadings on the main mineralization stage suggest a distinct geochemical characteristic of JGD relative to both Carlin-type deposits (CTD) and Carlin-like deposits (CLD); hence it is inferred to be a sedimentary-hosted gold deposit (SHGD). Establishing the JGD characteristics will contribute to a better understanding of the deposit and the BMD. Exploration-wise, it will assist future exploration work in delineating Au mineralization zones.

Full textAbstract:
The present study was conducted to determine if there were effects of increasing levels of dietary zinc supplementation on the turnover of zinc and other minerals and trace elements in growing pigs. Thirty crossbred female pigs, with an initial body weight of approximately 25 kg, were randomly assigned to five diets with increasing levels of supplemented zinc (as zinc oxide); i.e. from the intrinsic level of 42 mg kg−1 diet to 72, 105, 170, and 255 mg kg−1, respectively. The animals were subjected to two 7-d balances in metabolic cages, separated by 15 d in pens. Balances consisted of controlled feed intake, i.e. approximately 10% below the expected ad libitum intake, and quantitative collection of feces and urine. Zinc supplementation did not affect nitrogen absorption, excretion, or retention (P > 0.05). The inclusion of zinc oxide did not affect (P > 0.05) weight gain of the animals throughout the 34 d experiment. Neither mineral nor trace element balances, except for zinc, were affected (P > 0.05) by zinc supplementation. Urinary excretion of zinc was not affected (P > 0.05), but zinc absorption and retention calculated in absolute amounts or in proportion to nitrogen retention (i.e. lean body accretion) increased several-fold when diets were supplemented with zinc oxide. Mineral and trace element absorption in proportion to nitrogen retention appeared remarkably constant throughout the experimental period, although feed intake and body size increased with time. Only calcium absorption and retention, determined in proportion to nitrogen retention and as fractions of ingested calcium increased (P < 0.001), 14 and 9%, respectively, with time. In general, mineral and trace element absorption and retention, expressed in proportion to nitrogen retention, appear to be a useful expression for comparisons between observations across time intervals. Key words: Zinc, absorption, retention, interaction, minerals, trace elements

Abstract Various minerals in Kelulut honey possess a high value in human health and are crucial in regulating multiple biological metabolisms. However, each mineral from different honey sources needs to be monitored to avoid contamination and food poisoning. In addition, the amount of minerals content varies based on geographical region and nectar sources. This study aims to identify and determine the minerals content in Kelulut honey samples collected from different locations on the West Coast of Sabah. The samples were analyzed using ICP-OES, and a total of 20 minerals elements (Ag, Al, As, Ca, Co, Cr, Cu, Fe, Ga, K, Li, Mg, Mn, Na, Rb, Se, Sr, Ti, V, and Zn) were presented. The most abundant minerals which are categorized as macro minerals present in all the samples are K (1821.253 ± 35.16 mg/kg), followed by Na (371.00±5.06 mg/kg), Ca (338.643±3.07 mg/kg), and Mg (98.899±1.77 mg/kg). While from the group of minor minerals, Zn had the highest amount with a mean concentration of 6.38±10.35 mg/kg, followed by Mn (2.04±1.61 mg/kg), Cu (1.26±2.97mg/kg). No toxic elements were detected except for Ag (0.06±0.01 mg/kg), considered unbeneficial minerals, and the concentration was considered no harmful effect on the biological system.
