Abstract:
Intracellular iron can be estimated semi-quantitatively by histochemical determination using the ferrocyanide reagent's score. Particle-induced X-ray emission (PIXE) allows accurate determination of various elements including iron in cells and biological fluids. Both techniques have been used to measure iron in alveolar macrophages gathered by bronchoalveolar lavage. The purpose of this study was to investigate the clinical usefulness of the PIXE technique in occupational respiratory medicine and in various pulmonary diseases. Using the PIXE method, we measured the iron content of alveolar macrophages in healthy subjects, with and without occupational exposure to iron dust, and in patients with pulmonary diseases (chronic obstructive pulmonary disease (COPD), lung cancer, Goodpasture's syndrome). Our results were then compared with those obtained with the ferrocyanide reagent. Intramacrophagic iron was 0.33 +/- 0.21 micrograms.10(-6) (mean +/- SD) cells in healthy non-smoking subjects without occupational exposure. Intramacrophagic iron was increased in smokers, iron-steelworkers, and in patients with COPD or lung cancer even in the absence of pulmonary haemorrhage. The two patients with Goodpasture's syndrome had high intramacrophagic iron content. About 80% of the whole bronchoalveolar lavage fluid iron content was in the cells. Mean iron content of blood monocytes, lymphocytes and neutrophils of eight healthy subjects was significantly lower than that of alveolar macrophages. A significant correlation was found between iron determination by the PIXE method and the ferrocyanide reagent's score (r = 0.89). We conclude that intramacrophagic iron may be increased in steelworkers and subjects with pulmonary haemorrhage, but also in asymptomatic smokers, in COPD and lung cancer patients without occupational exposure to iron dust.

Abstract:
Abstract Introduction: Deferasirox (ICL670) is a novel tridentate oral iron chelator currently being evaluated for the treatment of transfusional iron overload. Phase III clinical trials have demonstrated that once-daily ICL670 (20 mg/kg) is equally effective at controlling liver iron concentration as standard deferoxamine therapy (40 mg/kg/day, 5 days per week). While ICL670’s long serum half-life should offer good protection against cardiac iron accumulation, little is known regarding its ability to remove stored cardiac iron. Therefore, we compared the relative efficacy of ICL670, deferiprone (L1), and deferoxamine (DFO) in removing cardiac iron from iron-loaded gerbils. Methods: 37 8–10 week old female gerbils underwent ten weekly iron dextran injections of 200 mg/kg/D, followed by a 13 day equilibration period. Five animals were then sacrificed to determine pre-chelation iron burdens. Chelation was initiated in 3 groups of 8 animals (ICL670 100 mg/kg/D po QD, L1 375 mg/kg/D po divided TID, DFO 200 mg/kg/D sub Q divided BID) five days per week and maintained for 12 weeks. The remaining 8 animals received sham chelation. All animals underwent ECG and treadmill assessment at baseline, following iron loading, and after completing chelation therapy. Animals were sacrificed for liver and heart iron measurement (Mayo Medical Laboratory) and semiquantitative histology. Hearts were evaluated for iron loading/distribution, tissue fibrosis, and myocyte hypertrophy, while livers were scored for iron loading/distribution and fibrosis. Results: Chelator-independent iron excretion and redistribution was evident, unlike in humans. Cardiac and liver iron contents fell 30.4% and 23.2%, respectively, with sham chelation; all subsequent chelator comparisons are reported with respect to the sham-chelated animals. ICL670 reduced cardiac iron content 20.5%. There were no changes in cardiac weight, myocyte hypertrophy, fibrosis, or wet-to-dry weight ratio. ICL670 treatment reduced liver iron content 51%. Iron elimination was greatest in hepatocytes with no detectable Kupfer-cell iron clearance. L1 produced comparable reductions in cardiac iron content (18.6%). Wet weight cardiac iron concentration fell nearly 30% but this was offset by greater cardiac mass (16.5% increase). Histologic analysis demonstrated decreased iron staining but increased myocyte hypertrophy. L1 decreased liver iron content 24.9%. Wet weight liver iron concentration fell 43.8% but was offset by a 30% increase in liver weight and water content. Iron elimination was balanced between Kupfer cells and hepatocytes. DFO did not reduce biochemically-assayed cardiac or liver iron content, although it improved histologic iron scores in both organs. Hearts from DFO treated animals were enlarged and had greater fibrosis. Cardiac and liver iron contents were closely correlated (r = 0.66), but ICL670 animals had lower hepatic iron contents for any given cardiac iron content. Iron loading broadened QRS duration by 10.6%; this effect was antagonized by both L1 and ICL670 therapy. PR, QRS, and QTc interval were weakly correlated with cardiac and liver iron contents. Treadmill exercise time was independent of chelation therapy. Conclusion: ICL670 and L1 were equally effective in removing stored cardiac iron in a gerbil animal model but ICL670 removed more hepatic iron for a given cardiac iron burden.

Abstract:
The aim of this work was to determine in an exploratory manner the effect of excessive iron supplementation on iron, zinc, and copper contents in pork and pork offal. Pigs averaging 50 days in age and 15 ± 1.3 kg body weight were allocated to a control group (500 ppm dietary Fe) and a supplemental group (3000 ppm dietary Fe). After an iron supplementation period of 60 days, blood samples were analyzed to determine iron biomarkers, serum copper, and zinc contents. Animals were slaughtered to assess total iron, non-heme iron, heme iron, zinc, and copper contents in samples of nine meat cuts and some offal. Iron supplementation improved the iron status in pigs with increased hemoglobin and hematocrit, but did not affect serum levels of iron, zinc, and copper. Iron supplementation did not affect the heme and non-heme iron contents of the different meat cuts. Zinc contents decreased by 32–55% in meat cuts, where iron content increased in the liver, spleen, kidneys, and pancreas. No differences of zinc and copper were observed in offal samples. High concentrations of iron supplementation reduce zinc content in pork.

The hemoglobin content of reticulocytes (Hb-ret) is an effective real-time hemoglobin synthesis status indicator that permits diagnosis and monitoring of iron deficiency and iron deficiency anemia in all age groups with or without underlying diseases, including beta thalassemia. Hb-ret is less invasive than bone iron examination, less expensive than iron biochemical tests and might be available even in local laboratories. This review covers reports published mainly in 2020 and some other studies dedicated to clinical application of Hb-ret measured by Sysmex hematology analyzers.

Abstract:
Iron and manganese are essential microelements on plant growth but no information is known with regard to their content on Lantana camara L. subsp. camara (lantana) treated with drenched-applied paclobutrazol. Thus, the effects of drenched-applied paclobutrazol [0 (control), 40, and 80 mg l-1] on leaf iron and manganese contents of lantana plants were investigated testing two light regimes, resulted from the establishment of different shading levels, 0% (daily light quantity of 27.8 mol m-2 d-1) and 66% (9.4 mol m-2 d-1) in a glasshouse in Attica, Greece. Possible correlations between the studied minerals contents (iron and manganese) and specific leaf area were examined. Analysis of variance showed that iron and manganese contents were affected by shading level, paclobutrazol, their interaction and paclobutrazol, respectively. Iron content increased significantly after treatments with paclobutrazol, compared to control, at full light environment (0% shading). Leaf manganese content presented no significant increase with the increasing paclobutrazol concentrations at 0% and 66% shadings. No significant differences were noted (dispensing control plants) on iron and manganese contents, when examining plants which were treated with the same paclobutrazol concentration, between the studied light environments. From the linear correlation analysis, manganese content exhibited a significant negative correlation with specific leaf area which was not shown by the iron content. The results of the present study could contribute to establishing iron and manganese sufficiency ranges on L. camara, especially after treatments with different light environments and paclobutrazol

Abstract:
The effect of iron and manganese concentration on the morphology of complex intermetallics and their influence on the mechanical properties and microstructure has been studied in an Al-16.67 wt. % Si alloy with three content of iron (0.4, 1.2, 1.8 wt.%), and two different content of manganese, i.e. 0.6 and 0.9 wt.%. The intermetallic compounds are formed at high iron contents or at high concentrations of manganese with low iron. The microstructural investigation by Clemex software showed that the biggest intermetallic size reached the surface area of 12750 μm2, when the amount of iron was increased from 1.2% to 1.8% wt.%. It was also showed that the volume fraction of intermetallic compounds increases as the iron and manganese content increases. Formation of complex intermetallic phases with iron adversely affects tensile strength decreasing from 229MPa with 0.4 wt.% of iron to 187MPa when iron content was increased to 1.8 wt.%.

Abstract:
Built and put into operation experimental industrial and industrial installations and cast iron desulfurization departments ensured a reduction of sulfur content in cast iron to 0.005-0.010% in industrial conditions. The purpose of the work is to reliably predict the calculation of the necessary consumption of magnesium from various conditions - the initial sulfur content, the mass of cast iron and the given final sulfur content to ensure the reduction of desulfurization costs. In addition, it is important to predict the current content of sulfur in cast iron depending on the consumption of magnesium in order to increase the reliability of the achieved content of sulfur in molten iron. The developments carried out to assess the regularities of the processes of out-of-furnace desulfurization of cast iron by monoinjection of granular magnesium made it possible to obtain calculation models for the assessment of existing and newly built capacities for desulfurization of cast iron in ladles of different sizes (40-350 t) at different initial sulfur contents in cast iron (0.02-0.07 %) and requirements for the final content of sulfur in cast iron (≤0.002-0.015%). Calculation models are presented.

Abstract:
Background: Cowpea is a very popular crop in Brazil, rich in nutrients that can be used as food to feed the population, avoiding deficiencies caused by the lack of minerals such as iron and zinc. Objective: To select elite cowpea lines for biofortification of iron and zinc and determine the physical and chemical characteristics of the lines. We analyzed: 33 cowpea genotypes, being 31 elite genotypes and two biofortified cultivars (control). Method: The 10 best lines with iron and zinc contents were selected and, together with the controls, were analyzed for chemical composition (moisture, ash, lipids, proteins and carbohydrates), total energy value and cooking time. Results: The iron and zinc contents in semi-prostrate genotypes were higher than those in semi-erect genotypes, all the semi-prostrate lines presented a high iron content, and 19.25% presented a high zinc content. The genotypes of the semi-erect lines exhibited more significant genetic variability for iron content, whereas those of the semi-prostrate genotypes showed more significant genetic variation for zinc content, both exhibited a high genetic component in phenotypic expression. Improving the genotypes for increased protein content led to reductions in lipid and carbohydrate contents, as well as the total energy value, whereas increasing the carbohydrate content increased both the total energy value and the zinc content. The MNC04-792F-146 lines presented alleles that favored an increase in carbohydrate content and total energy, while the MNC04-769F-26, MNC04-769F-31, and MNC04-774F-90 lines were shown to be good sources of genes for increasing protein content, decreasing lipid content, and rapid cooking. Conclusion: The MNC04-762F-9, MNC04-792F-146, and MNC04-769F-55 lines exhibited the greatest potential to be released as iron and zinc biofortified cultivars.

Abstract:
ABSTRACT Hookworm infection is associated with growth delay and iron deficiency anemia in developing countries. A series of experiments were designed in order to test the hypothesis that host dietary iron restriction mediates susceptibility to hookworm infection using the hamster model of Ancylostoma ceylanicum. Animals were maintained on diets containing either 10 ppm iron (iron restricted) or 200 ppm iron (standard/high iron), followed by infection with A. ceylanicum third-stage larvae. Infected animals fed the standard diet exhibited statistically significant growth delay and reduced blood hemoglobin levels compared to uninfected controls on day 20 postinfection. In contrast, no statistically significant differences in weight or hemoglobin concentration were observed between infected and uninfected animals fed the iron-restricted diet. Moreover, iron-restricted animals were observed to have reduced intestinal worm burdens on day 10 and day 20 postinfection compared to those of animals maintained on the standard/high-iron diet. In a subsequent study, animals equilibrated on diets containing a range of iron levels (10 ppm, 40 ppm, 100 ppm, or 200 ppm) were infected with A. ceylanicum and followed for evidence of hookworm disease. Infected animals from the intermediate-dietary iron (40- and 100-ppm) groups exhibited greater weight loss and anemia than those in the low (10-ppm)- or high (200-ppm)-iron diet groups. Mortality was also significantly higher in the intermediate-dietary-iron groups. These data suggest that severe dietary iron restriction impairs hookworm development in vivo but that moderate iron restriction enhances host susceptibility to severe disease.

Abstract:
Abstract Liver is a heterogeneous organ central for the control of systemic iron homeostasis. Among the different cell types, only hepatocytes (parenchymal cells) produce the iron regulatory hormone hepcidin. Hepcidin binds to the iron exporter ferroportin and triggers its degradation , thus modulating iron absorption from the diet and iron release from macrophagesdistrib. The iron-mediated hepcidin response is controlled via the SMAD1/5/8 pathway which is activated by bone morphogenetic proteins (BMPs). In contrast to hepcidin, BMPs are mainly produced by liver non-parenchymal cells, questioning the exclusive role of hepatocytes in regulating iron homeostasis. In particular, liver sinusoidal endothelial cells (LSECs) are emerging as cells that sense iron availability and modulate hepcidin levels through the production of BMP2 and BMP6 - the main regulators of hepcidin. However, how LSECs sense iron and which signals control BMP2 and BMP6 production have to be clarified. We have generated a mouse model with heterozygous depletion of the ferroportin allele (Slc40a1wt/trp). These mice show normal haematological parameters, serum iron levels and transferrin saturation. However, the liver is iron deficient and expresses low levels of hepcidin. The phosphorylation of SMAD1/5/8 proteins is lower in Slc40a1wt/trp compared to wild type littermates, explaining the hepcidin phenotype. To further investigate the molecular mechanism underlying hepcidin downregulation mediated by hepatic iron deficiency, we established a protocol to isolate hepatocytes and LSECs from total mouse liver and analyzed expression of iron-related genes. BMP6 is downregulated in LSECs of Slc40a1wt/trp mice, explaining the diminished activity of the SMAD1/5/8 signaling pathway. We next examined intracellular iron levels in hepatocytes and LSECs by measuring ferritin (Ft) and transferrin receptor 1 expression (Tfr1), two genes whose expression is regulated via the IRE/IRP system according to intracellular iron stores. Hepatocytes have an iron-deficient molecular signature, with low levels of Ft and a high expression of Tfr1. Surprisingly in LSECs both Ft and Tfr1 are unchanged, suggesting that this cellular population has unaltered iron levels. Taken together, our results show for the first time that decreased hepatic iron content is self-sufficient to cause a dramatic reduction in hepcidin expression and secretion. The hepcidin downregulation in the Slc40a1wt/trp mouse model is caused by a reduction in BMP6 levels that correlates with hepatocyte iron content. BMP6 modulation cannot be explained either by differences in circulating iron or by altered intracellular iron levels of LSECs, suggesting that BMP6 is not regulated by LSEC-mediated iron sensing. In our mouse model BMP6 seems to be linked with the intracellular iron content of hepatocytes. Therefore, we hypothesize that hepatocytes are the sensor of liver iron content which controls BMP6 expression in LSECs. RNAseq analysis on hepatocytes from Slc40a1wt/trp mice has been performed to identify underlying mechanisms. Disclosures Muckenthaler: Novartis: Research Funding.

Abstract:
In order to study the effect of iron content on the pitting corrosion behavior of a Ni-Cr-Mo alloy coating in a simulated seawater environment, a Ni-Cr-Mo-xFe (x = 0, 5, 10, 15, 20, 25) alloy coating was prepared through laser cladding technology. These coatings primarily consist of a γ-Ni solid solution phase, with observable iron segregation in the interdendritic regions when the iron content reaches 25 wt%. After 42 days of salt spray corrosion, it was found that pitting began to appear on the surface when the iron content in the coating increased to 10 wt%. The results of electrochemical behavior revealed that the coatings with iron contents in a range of 10–25 wt% exhibited metastable pitting characteristics, and the impedance modulus decreased with the increase in iron content. Pitting corrosion occurs due to selective corrosion of the dendritic regions. When the iron content exceeds 10 wt%, the accumulation of iron in the outer layer of the passivation film would lead to an excess of cationic vacancies, and the stability of the passive film is then reduced. This study provides a reference for the control of the iron content in a Ni-Cr-Mo alloy coating when applied in marine environments.

Abstract:
Objectives: To describe the iron content of commercially available infant and toddler foods. Methods: Nutrition Facts label data were used from a 2015 database of 1037 commercial infant and toddler food and drink products. Products were grouped into food categories on the basis of name, ingredients, target age, and reference amounts customarily consumed (RACC). Mean and median iron content per 100 g and per RACC were calculated. The proportion of products considered good and excellent sources of iron were determined on the basis of percent daily value (% DV) thresholds. Results: Among products marketed for infants (aged 4–12 months), infant cereals had the highest mean (6.19 mg iron per RACC; 41.25 iron mg per 100 g) iron content. Among products marketed for toddlers (aged 12–36 months), vegetable-based mixtures or meals contained the highest mean iron in mg per RACC (mean: 2.97 mg) and dry, grain-based desserts had the highest mean iron in mg per 100 g (mean: 6.45 mg). Juice and drink products had the lowest mean iron contents in both infant and toddler products. Conclusions: Most commercially available infant cereals are considered to be an excellent source of iron, likely from fortification, but wide variability was observed in iron content by food category. Products that are considered good or excellent sources of iron (≥10% DV) can help consumers identify products with higher iron content, such as infant cereals or toddler vegetable-based mixtures/meals.

Abstract:
Iron is an essential micronutrient for the normal metabolism of all cells. Intracellular iron varies within normality ranges, and depletion or overload of brings serious consequences. As such, iron can also be deleterious when appearing as an environmental toxicant. The aim of this study was to estimate semi-quantitatively the liver iron content in female Ohrid trout, from the Lake Ohrid, during the breeding cycle. Seasonal variations in hepatocytic iron were observed. The maximum content occurred at post-spawning, which was significantly higher than loads detected at pre- and early-vitellogenesis. Positive correlations existed between iron amounts and stages of ovary maturation. By the contrary, there were no correlations between iron contents and plasma oestradiol levels. The new uncovered "iron-breeding associa-tion" strongly endorses that normal seasonal variations in hepatocytic iron content should be taken into consideration in field studies investigating and monitoring the metal burden and toxicological effects of metals on wild fish.

The aims of the experiments were to evaluate the effects of iron application methods (soil or foliar alone and a combination of soil + foliar) on the Fe content in brown rice grain and to compare the grain yields of three rice cultivars, namely Chinat1 (poor Fe grain concentration), Riceberry and Tubtim Chumpae (rich Fe grain concentration). The results show that all iron application methods significantly increase the iron content of brown rice grains in comparison with non-iron application in two cropping years. The iron application to the soil combined with foliar gave the highest iron content in the brown rice grain. However, the responses to the iron application methods were different among rice cultivars. The highest grain iron contents of Chainat1 and Riceberry were shown in the combination of soil and foliar application, whereas Tubtim Chumpae had the highest grain iron content in the foliar application alone. The differences in grain yield were affected by the rice cultivar, but not by iron application methods. The Chainat1 produced the highest grain yield. In addition, Chainat1 had the strongest correlation between brown rice grain iron content and grain yield for both cropping years.

Abstract:
Dracocephalum moldavica L. of the Labiatae family is an annual herbaceous plant. In Iran it is known as Badrashbi and Badrashboo. Recent publications have reported antibacterial and antimicrobial properties of its essential oil, which have a wide usage in industry. In this research, the effects of iron foliar application and different yields’ harvest times on the essential oil content and some morphological treats (plant height, branch number, fresh and dry weights, essential oil content and leaf Iron content) were investigated under experimental study in faculty of Agriculture of Urmia University during 2012. A factorial experiment in a randomized complete block design with three replications was used in the present study. Results showed that foliar application of iron had a significant effect on branch number, fresh and dry weight, biomass and oil percentage. Similarly, harvest time had a significant influence on fresh and dry weight, essential oil content, essential oil yield and leaf iron content, but its effect was not significant on stem diameter and branch number. The best harvest time for Dracocephalum moldavica L. was at 100% of flowering and 6 ml/l of iron application showed the best results in all characters measured.

Abstract:
The aquatic chemistry of iron involves many environmental aspects because dissolved iron is present as ferrous and ferric ion and the equilibrium between these two forms depends on many natural or antropogenic factors. This paper aims to provide a brief introduction to chemistry of iron in an oligotrophic lake, a new topic in this domain. A number of 28 sampling were taken from Catamarasti Lake, Botosani (Romania). The main physico-chemical properties showed that the acidity, dissolved oxygen, electrical conductivity and saturation satisfied the water quality criteria for this ecosystem. The results for dissolved iron species indicated that there is no strictly correlation with the variation of oxygen content. Thus, for the samples from NE shore, the contents of ferrous iron are bigger than of ferric iron, for the samples from SW shore the contents are almost equal, because of the low contents of oxygen. For the samples from the middle and from downstream of the lake, the contents of ferric iron are bigger than of ferrous iron, due to the oxygen content recorded.

Abstract:
The aim of this study was to determine the iron content of Malawian foods prepared in iron pots and to examine the effects of continuous cooking time and added oil on the iron content of the food prepared. Foods prepared, which included a staple (Nsima), relish vegetables, and beans, had an increased iron content when prepared in an iron compared to a glass pot. For these three foods, iron content per gram increased by 3.15 mug, 35.8 mug, and 147.32 mug, respectively. Continuous use of the iron pot for cooking could have a positive effect on the amount of iron added to the food, as the three foods' iron content increased by a further 2.9 mug iron/g, 7.6 mug iron/g and 20.1 mug iron/g, respectively. This effect needs more study. Food pH was significantly negatively correlated with food iron content. The use of oil reduced the amount of iron added to stir-fried vegetables by 52.37 mug/g and increased iron added to Nsima (1.2 mug/g). Malawian foods increased their iron content when cooked in iron pots. This method of food preparation potentially provides a low-cost sustainable means of improving the iron intakes of families and communities where this traditional method of food preparation is acceptable.

Abstract:
Through industrial testing at the Huize lead-zinc mine, it was found that the floatability of sphalerite varied greatly with the iron impurity content. Three kinds of Huize sphalerites with iron contents of 2.30 wt.%, 3.20 wt.% and 4.66 wt.%, were used to study the influence of small amounts of iron impurity in the sphalerite on xanthate adsorption and flotation behavior. The flotation experiments showed that the flotation recovery increased with the increase in iron impurity content. Fourier Transform infrared spectroscopy (FTIR) and Ultraviolet–visible (UV-VIS) spectra showed that the adsorbed products of xanthate on the surface of three kinds of sphalerite were metal xanthate. The adsorption capacity measurements showed that the saturation absorption of xanthate on sphalerite increased with the increase in iron impurity content. The cyclic voltammetry curve and Tafel curve showed that with the increase in iron impurity content, sphalerite was more easily oxidized and the adsorption rate of xanthate on the surface of sphalerite increased obviously. To summarize, a small amount of iron impurity was beneficial to the recovery of sphalerite.

Abstract:
In this paper, the influence factors on high compressibility water atomized iron powder LAP100.29 were studied such as the processing parameters, the proportion of coarse particles, powder oxygen content and impurity. The results showed that, by increasing the purity of molten steel and improving atomization temperature, the iron content of water atomized iron powder particles reached more than 99.67 %, the oxygen content was less than 0.08 %, acid insoluble was less than 0.08 %, green density reached 7.21~7.22 g/cm3. The contents of +80 and -80～+100 mesh powder were 1.6 % and 7.5 %, respectively. The compressibility could be improved by the increase of the coarse particles and the reduction of the fine particles (for example, lowering the content of -325 mesh particles). Generally speaking, the compressibility of the water atomized iron powder can be improved fundamentally by reducing oxygen content, impurity content and the reasonable distribution of particle size.

Abstract:
Soil iron has an important impact on the ecological environment and on crop growth. This study selected a typical small watershed basin in the middle reaches of the Han River (Yujiehe) at Ankang City and used geostatistical methods and kriging interpolation to analyze the spatial distribution and structure of soil iron content for different land uses and at different depths, using the single-factor pollution evaluation to evaluate the pollution degree of soil iron. The results showed that soil iron in the Yujie River basin decreased with increasing soil depth, with contents of 8.80 mg/kg, 5.52 mg/kg, and 4.92 mg/kg at depths A1 (0–20 cm), A2 (20–40 cm), and A3 (40–60 cm). According to the classification index of effective trace elements in soil, the average contents of soil iron at these three depths were between 4.5 and 10 mg/kg, which are all considered moderate values. The coefficients of variation of soil iron at the three soil depths were 59%, 75%, and 83%, all of which showed moderate spatial variability, and the coefficient of variation increased gradually with soil depth. With semi-variance calculated at the three soil depths, soil iron optimal theoretical models were all exponential models with nugget coefficients of 9.52%, 47.76%, and 33.93%, indicating that spatial correlation was very strong in the A1 layer and moderate in the A2 and A3 layers. The spatial distribution of soil iron showed some variation in the study area, and the soil content was higher in the midwestern part in the A1 and A2 layers; however, in the A3 layer, the higher content was in the center and lower content was in the southern region. Correlations were significant between soil iron content on the one hand and land-use type and topographic factors on the other. The pollution indices of soil iron at the three soil depths under different land uses were all greater than 1.0, with the A1 layer in farmland being the worst, at 3.34. In the study area, using the background value of soil iron as an evaluation standard, the soil iron content of more than 65% of the Yujiehe region exceeded this standard.

Abstract:
Soil of arable land and meadows from the Ap horizon, taken from ten different localities, were investigated for different forms of Fe, including total (HF), pseudo-total (HNO3), 0.1M HCl extractable and DTPA-extractable. A sequential fractional procedure was employed to separate the Fe into fractions: water soluble and exchangeable Fe (I), Fe specifically adsorbed with carbonates (II), reducibly releasable Fe in oxides (III), Fe bonded with organic matter (IV) and Fe structurally bonded in silicates (residual fraction) (V). The soil pH, CEC, and size fractions (clay and silt) had a strongest influence on the distribution of the different forms of Fe. The different extraction methods showed similar patterns of the Fe content in arable and meadow soils. However, the DTPA iron did not correspond with the total iron, which confirms the widespread incidence of iron-deficiency in vertisols is independent of the total iron in soils. The amount of exchangeable (fraction I) and specifically adsorbed (II) iron showed no dependence on its content in the other fractions, indicating low mobility of iron in vertisols. The strong positive correlation (r = 0.812 and 0.956) between the content of iron in HNO3 and HF and its contents in the primary and secondary minerals (fraction - V) indicate a low content of plant accessible iron in the vertisol. The sequential fractional procedure was confirmed as suitable for accessing the content and availability of iron in the vertisols of Serbia.

Abstract:
Cyanobacteria are characterized by high iron content. In this research, we collected ten commercial samples of Arthrospira spp. sold as food supplement to determine iron content and assess whether iron speciation showed variability among samples and changed respect to A. platensis grown in controlled conditions. Particular attention was also paid to phycocyanin, as an iron-binding protein. In six of the ten samples, 14 essential and non-essential trace elements were analysed using ICP-MS. Iron content measured in samples using atomic absorption spectrometry (AAS) varied from 353 (sample S5) to 1459 (sample S7) µg g−1 dry weight and was in the range of those reported by other authors in commercial supplements. Iron speciation was studied using size exclusion chromatography followed by the analysis of the collected fraction for the determination of iron by AAS and for protein separation using SDS-PAGE. Overlapping chromatographic profiles were obtained for total proteins, phycocyanin and iron, although quantitative differences were evidenced among the samples analysed. In most samples, iron was mainly bound to ligands with high molecular mass; however, in four samples iron was also bound to ligands with low molecular mass. In fractions containing the most relevant iron burden, the principal protein was phycocyanin, confirming its role as an iron-binding protein in commercial samples.

Abstract:
Spinach ( Spinacia oleracia) and amaranth ( Amaranthus tricolor) leaves were stored in polyethylene bags and without packing for 24 and 48 hours in a refrigerator at 5°C and 30°C in polyethylene bags. The fresh leaves were also dried (oven and sun), blanched (5, 10 and 15 min) and cooked in an open pan and a pressure cooker. The processed leaves were analysed for total iron, its availability and antinutrient content. The iron content of these leaves varied from 26.54 to 34.14 mg/l00g, dry weight and its HCl-extractability and in vitro availability were 62.11–67.18% and 3.03–3.97% of total respectively. Drying and storage had no significant effect on total iron content, Hel-extractability and availability ( in vitro), while blanching and cooking resulted in significant improvement of iron availability, and a significant reduction in oxalic acid content, while only blanching significantly reduced phytic acid and polyphenol contents. Thus cooking and blanching are good ways to improve HCl-extractability and in vitro availability of iron.

Abstract:
The iron dating project Aikarauta has been launched in Finland. This paper presents the results of the preliminary investigations. The ability for radiocarbon measurement by accelerator mass spectrometry (AMS) of iron in Finland has been demonstrated by using coal-produced iron as reference material. An elemental analyzer has been harnessed to measure the carbon content of small iron samples. In addition, we have hypothesized that a fingerprint of the limestone usage in the smelting process is the high Ca content of iron and slag. This has been examined by performing an iron smelting experiment with limestone as flux, by making elemental analyses of ingredients and the resulting slag and iron, and by a 14C analysis of the produced iron. It is possible that limestone dilutes the 14C contents of the produced iron, making its age determination challenging.

Abstract:
Iron ore with high hydroxyl content such as goethit is widely spread in Indonesia. Such iron ore is not used as feed in ironmaking industry. However due to limitation of primary iron ore reserve such material is an option to substitute the conventional iron ore. Unfortunately the characteristic of iron ore with high hydroxyl content is totally different to conventional iron ore. Such iron ore contains hydroxyl part that can be released at high temperature. This research uses composite pellet which is mixture of iron ore and coal. The iron ore contains goethite which is one of iron phase. The composition of two materials is fixed 1 to 3 molar for iron total to fixed carbon. The mixture is formed a pelet before dried. The small part of dry pellet is analysed using STA with 0.6667 °K/s. The reduction is characterised based on thermogravimetry graphs. The research found that the reduction of iron ore occurs in some stages. First stage correspond to dehydroxylation at around 300 °C and second stage corresponds to reduction of iron ore at around 625 °C and 825 °C or 880 °C. The composite lost of 4.64 % and 2.85 % of weight. The hydroxylation is followed by reduction. Hydroxylation transforms goethite to hematite with lost of water. While the reduction transforms hematite to magnetite and magnetite to Fe.

The mineral contents in common bean seeds are influenced, in addition to genetic variation, by environmental crop conditions, especially by the soil type and chemical composition and by the genotype x environment interaction. This study was carried out to verify if the zinc and iron contents are affected by the crop growing period. Ten lines with high iron and zinc contents and ten with low contents were assessed in three seasons: "wet season" of 2009/2010 (sowing in November); "dry season" of 2010 (sowing in February) and "winter season" of 2010 (sowing in July), in Lavras, Minas Gerais State, Brazil. The experimental design used was randomized blocks with three replications and plots consisting of two rows of two meters, with a spacing of 0.50 m. The seeds harvested were assessed in regard to iron and zinc mineral contents. The greatest contents were observed in the winter season and the smallest ones in the dry season, with sowing in February. It was observed that in the mean of the three harvests, the lines classified as having high iron and zinc content exhibited an iron quantity 11.0% and a zinc quantity 6.8% above those of low content. The lines by seasons interaction occurs. However, its interference in identification of the groups with high and low content of the two nutrients is not great.

Abstract:
The present investigation consists of 98 genotypes (two CMS lines, 30 testers, 60 hybrids and six checks) studied to assess the magnitude of genetic variability and character association of iron, zinc and protein with other agronomic traits. Pearl millet grain has rich iron content, zinc content and protein and are essential for human nutrition. Estimation of genetic parameters viz., variability, heritability, genetic advance will provide the basis for selecting systematic breeding strategy to improve the genotypes with desirable traits. Moderate PCV and GCV values were observed for grain iron and protein content, high PCV and GCV values were observed for zinc content. Influence of environment on these traits is low because of the less difference between the estimates of GCV and PCV. High heritability coupled with high genetic advance as percent of mean was observed for zinc content. Strong correlation was observed between grain iron and zinc content and their weak correlations with other agronomic traits indicated there is a possibility to breed high grain Fe and Zinc contents simultaneously in different plant agronomic backgrounds might be suitable for different agro-climatic regions.

Abstract:
A detection chip is designed and manufactured to study the relationship between iron wear particle content in hydraulic oil and the detected variation of average inductance, which detects content of iron wear particle by means of micro channel - inductive. Through experiments, we obtained inductive values in the cases. The case is that the sizes of iron wear particle are the same, while the content of iron wear particle are different. Thus the curve between content of iron wear particle content and variation of average inductance was drawn. Experimental results show that the inductance value increases with the increase of the iron wear particle content in hydraulic oil. Experiments prove that the way is feasible for the detection of iron wear particle content in hydraulic oil. This study has an important significance for the realization of iron wear particle content detection in hydraulic oil.
