Abstract:

Control of the trace element content in tap water is particularly important for large industrial regions. The estimation of Cd, Pb, Cu, As, Ni, Zn, Mn, Hg, Se and Co concentration in the tap water of Kryvyi Rih city (Karachuny Reservoir) was accomplished using electrochemical methods, the most popular methods for determining the content of trace elements in natural objects and tap water. A simple and rapid method to determine trace elements in the tap water (Kryvyi Rih city) by inversion-voltammetry has been used. The concentration of trace elements was measured by voltammetricanalyzer AVA-2 device that implements the method of inversion voltammetry on a solid rotating electrode made of carbon material. The monitoring of the trace element content in the water of the Karachuny reservoir was carried out on a monthly basis between September 2018 and August 2019. The article presents the obtained voltamperograms of some trace elements, describes content of the trace element in tap water during the year (12 data for each trace element) and analyzes the compliance of drinking water in the city of Kryvyi Rih to the standards and normative indicators of drinking water quality.

Abstract:

Sales of bottled water have been increasing around the globe. This study was carried out to assess the trace elements present in bottled water. For the study of bottled water, a total of 100 samples of different volumes (20 L and 1 L) were selected. The physicochemical assessments were performed as per the methods described in the American Public Health Association, 2005. Average values of pH, electrical conductivity, total dissolved solids, and turbidity were found to be 5.96 ± 0.54, 59.97 ± 58.65, 4.42 ± 3.69, and 0.408 ± 0.19, respectively. Likewise, average values of total hardness (as CaCO3), calcium (as CaCO3), magnesium (as CaCO3), chlorine, iron, copper, cobalt, nickel, fluoride, sodium, and potassium were found to be 14.78 ± 8.43, 3.26 ± 1.55, 11.51 ± 7.92, 7.51 ± 3.21, 0.0032 ± 0.0017, 0.0091 ± 0.0116, 0.2520 ± 0.0127, 0.0080 ± 0.0082, 0.047 ± 0.0139, 12.65 ± 10.90, and 1.41 ± 2.00, respectively; meanwhile residual chlorine, zinc, silver, cadmium, and lead were below detection limit. All the physicochemical characteristics of bottled water were found to be within International Bottled Water Association (IBWA) guidelines. From the physicochemical aspects, the bottled water was found to be within the permissible value set by IBWA. Pearson’s correlation revealed significant association between trace elements. Levene’s test for equity of variances indicated that the majority (iron, copper, cobalt, nickel, fluoride, sodium, and potassium) of trace elements and seasons (monsoon and postmonsoon) demonstrated a statistically significant distribution (at 95% confidence interval). At elevated concentrations, some elements can be harmful to human health and can cause morphological abnormalities, mutagenic effects, reduced growth, and increased morbidity and mortality in humans but it all depends upon a person’s metabolic factors, genetic factors, and ability to excrete trace elements through different routes, etc. Water could have percolated down from the surface to the ground water and as such the difference in concentration of trace elements in monsoon and postmonsoon seasons could be noticeable.

Abstract:

Metallic trace elements toxicity has been associated with a wide range of morphological abnormalities in fish, both in natural aquatic ecosystems and controlled environments. The bioaccumulation of metallic trace elements can have devastating effects on several aspects of fish health, encompassing physiological, reproductive, behavioural, and developmental functions. Considering the significant risks posed by metallic trace elements-induced toxicity to fish populations, this review aims to investigate the deleterious effects of prevalent metallic trace elements toxicants, such as mercury (Hg), cadmium (Cd), chromium (Cr), lead (Pb), arsenic (As), and copper (Cu), on the neurological, reproductive, embryonic, and tissue systems of fish. Employing diverse search engines and relevant keywords, an extensive review of in vitro and in vivo studies pertaining to metallic trace elements toxicity and its adverse consequences on fish and their organs was conducted. The findings indicate that Cd was the most prevalent metallic trace elements in aquatic environments, exerting the most severe impacts on various fish organs and systems, followed by Cu and Pb. Moreover, it was observed that different metals exhibited varying degrees and types of effects on fish. Given the profound adverse effects of metallic trace elements contamination in water, immediate measures need to be taken to mitigate water pollution stemming from the discharge of waste containing metallic trace elements from agricultural, industrial, and domestic water usage. This study also compares the most common methods for treating metallic trace elements contamination in water.

Abstract:

Evaluation of trace elements in the water of Lancang River during the wet season (October) and dry season (December) was carried out to analyze the content of trace elements in the water, spatial and seasonal variations, enrichment, and health risks of dissolved trace metal. The results showed that the content of trace elements in the main stream of the upper Lancang River met the “Environmental Quality Standard for Surface Water” (GB3838-2002) Class I water-quality standard, but the Fe content in sampling points during the wet season exceeded the limit value of water-quality standard. Compared with other rivers in Tibet, the contents of As, Fe, and Pb in the study were relatively high. While Pb, As, and Zn were the mainly enriched trace elements. The water temperature, dissolved oxygen, conductivity, As, Cr, and Cu in the main stream of the upper Lancang River with significant seasonal variations. The content of trace elements in the front of the dam was lower than that in the tail and under the dam. The trace elements in the water of the reservoir area increased with an increase in the depth, and the reservoir had a certain interception effect on the trace elements. The As content in the main stream of the Lancang River was greatly affected by the branch of Angqu with high content of As. The HQingestion and HI of As in the part of the river in the study exceeded 1, and the water-quality health risks of the Guoduo reservoir tail and urban reaches were higher than those of other reaches, which should be paid more attention.

Abstract:

The pollution level of trace elements from nine types of fishes was study by ICP-AES techniques, and compare the pollution level differences of trace elements between fishes of fresh and marine waters. Assess the pollution risk of trace elements accumulated in fish tissues with the aquatic eco- environment from fresh and marine waters. The concentration changes of trace elements in fish tissues have some differences from freshwater fish tissues and marine water fish tissues, but the concentration distribution tendency of trace elements was similar. Mg elements had high concentration, Fe elements were rich in fish tissues, and Zn elements were in a relatively lower level in fish tissues. Their bioaccumulation levels with other trace elements, such as Mn, Cu, Ni, Co, Se, Cr, Mo, Sn and Al, were not considered as main contaminate elements in fish tissues, the pollution level of toxic elements like Cd, Pb and Hg in most fish tissues from this study demonstrated that the cultivation aquatic eco- environments of fresh water and marine water were relatively safe. But the potential pollutions of toxic elements in fish tissues, such as Cd, Pb, As and Hg should pay main attention.

AbstractSelected trace fossils from the type section of the ‘Etcheminian Series’ at Hanford Brook are described and illustrated:Helmithoidichnites tenuisFitch,Monocraterionsp.,Palaeophycus tubularisHall,Planolitessp.,Psammichnites gigasMatthew,Subphyllochordra?sp.,Taphrhelminthoida dailyin. sp., andTaphrhelminthopsiscf.T. circularisCrimes et al. The assemblage has elements comparable to those in other Lower Cambrian sequences. It formed in shallow water settings, is mainly endichnial, and contains systematic, guided meander traces that are generally characteristic of deep-water environments in younger sequences; this may be related to global environmental changes early in the Palaeozoic. The guided meander traces are characterized morphometrically, using an image analyser: the meander systems exhibit a strongly bimodal distribution of morphologic elements, reflecting a well developed taxis (sense for position, direction, and distance) during trace production. The method of morphometric analysis has potential for characterizing trace fossils generally, somewhat like X-ray diffractograms characterize minerals.

Abstract:

This research focused on a model setup fed with underground water pumped into a water supply network. The scope of the research included a long- and a short-term stagnation of water in the setup and a water flow of 0.1 m/s. The water supplied into the system gradually lost its corrosive properties and developed calcium carbonate precipitation capability. These processes indicated that cement components migrate from the lining into the water. Apart from the primary components, the presence of the following trace elements was found: iron (399.6 ppb), magnesium (17.8 ppm), zinc (26.9 ppb), barium (22.6 ppb), boron (21.6 ppb), sodium (10.8 ppm), gallium (2.1 ppb). At early stages of the operation, recorded quantities were not significant. Leaching of the trace elements from cement increased after water was chlorinated. In turn, the highest percent increases were observed in the case of zinc (217%), boron (19%) and gallium (12%), whereas the increase for sodium, iron, barium and magnesium in water was insignificant (reaching a few percent). A repeated analysis of samples of stagnant water in the setup showed that most of trace elements were below the detectability level. Final concentrations of all elements identified in the water after its contact with internal cement mortar lining were much lower than the limit values set out for drinking water.

Abstract:

1) ZINC: In 1963, Prasad found that dwarfism in Egypt was caused by zinc deficiency. Since then, many clinical pictures involving zinc deficiency have been reported on, such as alopecia (baldness), intestinal acrodermatitis (dermatitis of the extremities), alcohol-induced anencephalic children, and depressed immune response. 2) COPPER: Wilson’s disease is characterized by hepato-cerebral degeneration, which is caused by the deposition of copper in the liver and the cerebrum. Chelete therapy has been applied to remove the copper from the organs in order to treat Wilson’s disease. However, during the last several years zinc or manganese has also been applied to remove copper. The therapy mechanism is based on the interaction of copper to zinc and manganese. Zinc and copper deficiency is also an important topic in medical elementology. 3) MERCURY: Sir Isaac Newton was well known to be distrustful of others in his last years. The clinical picture was characterized by severe neuropathy, which was caused by heavy exposure to mercury during his long scholarly life. Children sometimes break thermometer in their mouth. Does metallic mercury in the thermometer induce mercury intoxication ? The answer is no. Intestinal absorption of metallic mercury is quite low, and thus ingested mercury rarely induces intoxication. The mercury is simply excreted through the feces within a day or two. One should attempt to wash the mercury out from the stomach with water. However, do not treat the child with laxatives, as they can increase the intestinal absorption of mercury, resulting in intoxication. 4) METHYLMERCURY: Severe neuropathy was endemic among fishermen and their families in a particular area of Kyushu Island, Japan. They were found to have eaten a great amount of fish, which were contaminated with organic mercury emitted from a fertilizer producing plant. The disease was later named as Minamata disease. The total number of recognized patients has amounted to 3,000 people, to date. 5) CADMIUM: Cadmium deficiency was recently found to depress the development of baby animals by Anke. This finding suggests that cadmium is not only a harmful element but also an essential element. Itai-Itai disease is characterized as osteomalacia, which is followed by severe renal tubular damage. Patients were comprised largely of elderly women who lived in the Jintsu river basin over a long period, and ingested excess cadmium emitted from a mine, which contaminated the local rice and drinking water. Long-term monkey experiments could not demonstrate osteomalacia by cadmium, however, epidemiological and experimental studies showed that an age-related increase in blood pressure is accelerated by cadmium at low doses, but depressed by cadmium at high doses. 6) LEAD: Lead is a very useful element, but a very harmful element as well. Lead has a potent hematopoietic effect on adults, and also negative psycho-neurological effects on babies. Soil pollution from lead has been discussed in relation to depressed intelligence among children living in U. S. slums. Sometimes residents in rural areas are shot with lead slugs by mistake. Do does lead slugs cause lead intoxication? Usually not. Medication is necessary only when lead slugs injure blood vessels or neurons. Most lead slugs do not induce lead intoxication because the lead slugs are soon covered with granular tissues. 7) CHROMIUM: Chromium is one of the essential trace elements, and is related to glucose tolerance and transmission velocity of peripheral nerves. Adverse effects of excessive chromium are chromium ulcers, perforation of the nasal septum, and lung cancer. 8) ARSENIC: Neutron activation analysis revealed excess amounts of arsenic in the hair of Napoleon. It was then suspected that he was killed with arsenic. Concerning the cause of his death, it was shown that grapes were disinfected with arsenic in those days, and that Napoleon might have consumed excess arsenic from drinking wine. However, the cause of his death remains unsolved. On the other hand, arsenic was used to promote health in Austria. Huge doses of arsenic, lethal for ordinary people, were administered to Austrian youths to assist them in Alpinc hiking. Japanese, especially residents in seashore areas, eat sizable amounts of sea weeds, which contain a huge amount of arsenic. Do they suffer from arsenic intoxication? The answer is no. The chemical form of arsenic in sea weeds is methyl-arsenic, the detoxicated chemical form, which does not revert to the active chemical form of arsenic.

Review study of trace elements in sediments of water bodies in the Amazon region, Brazil. ABSTRACTPollution by trace elements in watershed sediments has been increasingly studied in terms of ecological risk management. In this way, from a bibliographic survey in the period from 2012 to 2022, we sought to analyze and compare the effects arising from the trace elements that occurred in the sediments of water bodies located in the Amazon region. In this work, books and published articles were used, as a research tool, the "Academic Google", "Periódicos CAPES", "Scielo", "Science Direct" and "Web of Science Core Collection" was used. that essential trace elements participate in chemical reactions of human cellular metabolism, such as iron, manganese and among others are important in biological processes for human activities, in addition, trace elements interact in sediments and water bodies, and may make it possible to characterize the elements in the environment. The articles showed accentuated values for iron, which was related to the geological formation of certain Amazon region. Meanwhile, lead did not exceed the maximum value recommended by CONAMA Resolution 454/2012, indicating that the concentrations described in the articles are in accordance with that Resolution. The monitoring of trace elements in sediments is relevant to have a picture of the environmental conditions of water bodies in the Amazon region. The State can develop sustainable public policies to circumvent the effects of trace elements in the environment, based on knowledge of concentrations in sediments, biota and water.Keywords Watersheds; lead; zinc; iron; copper.

Abstract:

Drinking water is the essential medium for food production, and is also needed for direct consumption; while it must be free of harmful substances, it also must have a composition that is beneficial to health. The aim of this study was to evaluate the influence of water and wastewater treatment on reducing the concentrations of zinc (Zn), nickel (Ni), iron (Fe), manganese (Mn), copper (Cu), lead (Pb), and arsenic (As) in the Western Pomerania Voivodeship in Poland. The research was carried out in 2017–2019. The analysis was performed with inductively coupled plasma atomic emission spectrophotometry (ICP-AES). The concentrations of trace elements in drinking water were below maximum acceptable concentrations (MACs). Reductions in the most dangerous elements during water treatment fluctuated from 48.5% (As) to 97% (Pb). Wastewater treatment reduced the concentrations of analyzed elements by a range of 28.6 to 60.8%, and the most toxic elements (Pb and As) by over 50%. Trace element concentrations in treated wastewater were below MAC values, and ranged from 1.15% (Pb) to 6.23% (As) of MACs for toxic elements. The concentrations of both essential elements (Zn, Ni, Fe, Mn, Cu) and toxic elements (Pb, As) in drinking water were below the MACs. Water treatment had a significant (p < 0.05) effect on decreasing trace element concentrations.

Abstract:

Abstract The Oldman River in southern Alberta is a mainstem river used extensively by aquatic life, for community drinking water, irrigation water, recreation, and livestock watering. Therefore, maintaining the water quality of this important river is critical for watershed health. We collected water samples weekly from three locations on the middle reach of the Oldman River from 2004 to 2006. The locations were: Lethbridge Municipal Water Treatment plant (MWTP) (Site 1), Fort MacLeod MWTP (Site 2), and a river bank sampling location downstream of the latter site (Site 3). Water samples were analyzed for background physical and chemical variables, and for selected trace elements (Al, Fe, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, Zn). The aquatic life, community, irrigation, and livestock water quality guidelines at the three sites were most frequently exceeded by Cu (27-48%), Al (3.3-57%), Co (18-26%), and Al (2.3%), respectively. Concentrations of certain trace elements were highest in the spring or during years of above average precipitation, and were likely associated with increased loads of suspended sediments during high flow conditions. Turbidity, water temperature, electrical conductivity, river level, and precipitation generally had a positive effect, and pH had a negative effect on certain trace element concentrations.

Abstract:

Abstract Over 100 surface sediment samples from Lac St. Louis (St. Lawrence River) were examined for various microbial physiological types and densities. These organisms were correlated to the concent rat ions of trace elements (Ni, Co, Cr, V, Cu, Pb, Zn, As, Fe, Mn and Ti) and nutrients (P and organic matter). Results indicated a relationship between bacterial densities and trace element concentrations. Data also suggested there was an apparent indication of bacterial inhibit ion due to toxic substances in the lake sediment. Generally, high and low bacterial density zones existed in the sediment with low bacterial density zones being associated with high concentrations of trace elements. Because of the relationships and the distribution of trace elements and organic matter, the lake bottom exhibited a heterogeneous nature. The availability of trace elements in the surface sediments was assessed by determination of chemical species of the trace elements in solutions obtained by elutriation of the sediment with distilled water. Data and methodology are presented.

Abstract:

Human health and sustainable socio-economic growth are closely linked to water quality. Due to increasingly intense human activity, pollutants, and in particular trace elements, are entering the aquatic system and harming humans. The main objective of this study is to analyse and compare the impact of the trace elements on the water quality of natural springs. The concentrations of ten trace elements in 12 spring water samples collected in 2022 were analyzed using ICP-MS to determine the spatial variability of natural water quality in the Ouislane watershed. Nine major trace elements (boron, cobalt, chromium, copper, manganese, nickel, lead, zinc, and vanadium) were measured using the inductively coupled plasma mass spectrometry (ICP-MS) technique. The average values of these elements followed the descending trend: B > Ni > Cr > Co > Zn > Mn > V > Cu > Pb in spring water samples. Some trace elements measured in certain water samples exceed the upper limits set by Moroccan drinking water quality standards (NM) and the World Health Organization (WHO). From the principal components analysis (PCA), 83% of the variation is explained by the first three main components. B, Co, Cr and Ni have a strongly impact on water quality explain by their strong correlation with CP1 (R2 > 0.70). The calculated water quality index (WQI) values ranged from 61.18 to 95.11, with an average of 78.47. Approximately 17% of the water samples were categorized as excellent quality water (WQI < 50), with the remaining 83% classified as good quality water (50 < WQI < 100). According to the WQI index, all the natural spring waters investigated are deemed suitable for human consumption.

Abstract:

The diffusion of trace elements in mining wastelands has attracted widespread attention in recent years. Vegetation restoration is an effective measure for controlling the surface migration of trace elements. However, there is no field evidence of the effective riparian zone width in mining wastelands. Three widths (5 m, 7.5 m, and 10 m) of Rhododendron simsii/Lolium perenne L. riparian zones were constructed in lead–zinc mining wastelands to investigate the loss of soil, cadmium (Cd), copper (Cu), arsenic (As), lead (Pb), and zinc (Zn). Asbestos tiles were used to cut off connections between adjacent plots to avoid hydrological interference. Plastic pipes and containers were used to collect runoff water. Results showed that more than 90% of trace elements were lost in sediment during low coverage and heavy rainfall periods. Compared with the 5 m riparian zone, the total trace element loss was reduced by 69–85% during the whole observation period in the 10 m riparian zone and by 86–99% during heavy rain periods in the 10 m riparian zone, which was due to reduction in runoff and concentrations of sediment and trace elements in the 10 m riparian zone. Indirect negative effects of riparian zone width on trace element loss through runoff and sediment concentration were found. These results indicated that the wide riparian zone promoted water infiltration, filtered soil particles, and reduced soil erosion and trace element loss. Riparian zones can be used as environmental management measures after mining areas are closed to reduce the spread of environmental risks in mining wastelands, although the long-term effects remain to be determined.

Abstract:

Thermal springs are natural hydrogeological features which are highly affected by local volcanism or tectonic activity. Thermal springs are the best source of hydrothermal energy to heat houses and aid in the recovery of skin diseases. However, they consist of some heavy and trace metals such as arsenic, lead, zinc, copper, iron, and so forth. Somehow, the thermal springs of central Bamyan have become contaminated with some essential trace elements. Thus, this study was conducted to assess and determine the number of these trace elements in the thermal springs. To achieve these objectives, a preliminary survey, water sampling, and in situ measurements of physicochemical parameters were conducted in research areas. All the collected water samples were analyzed chemically to determine the amount of trace elements, including arsenic, barium, copper, iron, manganese, and zinc. The study shows that temperature ranged from 16 to 32 °C, while the average pH value was 6.25. Almost all of the trace elements showed an extremely high value of electrical conductivity (average: 5713 µS/cm) and significantly high total dissolved solids (average: 3063 mg/L). The average value of chloride was 797 mg/L, which is dramatically higher than standard values. In regard to trace element concentration, almost all thermal springs were heavily contaminated with arsenic and it was recorded as 100 µg/L in the eastern part of central Bamyan. The average amounts of barium, copper, iron, manganese, and zinc were 4.14, 6.05, 1.90, 1.76, and 0.74 mg/L, respectively. In conclusion, the water of the thermal springs of central Bamyan are not suitable for human consumption because of the significant amount of trace elements as well as the high-water quality index value. Using these springs for drinking and irrigation purposes has been deemed inappropriate.

Abstract:

The metal composition of water and bottom sediments of southern Lake Baikal tributaries was studied and the water migration coefficients for micro- and trace elements were calculated. The map showing the study area divided into zones according to their ability to provide the certain water quality was drawn. The significant differences in mineralization, macro- and trace element composition between Lake Baikal water and tributary waters were found out. It was shown that values of water migration coefficients calculated for macro elements are similar in southern and main tributaries whereas coefficient values calculated for trace elements are quite different. This is due to dissolved matter sources such as rocks and deep ground waters which chemical composition is not typical for landscapes of Lake Baikal basin. The contribution of southern tributaries to macro element composition of lake water is between 7 and 15%, whereas tributaries contribution to trace element composition can hardly be evaluated because of higher element concentrations in riverine waters. The lower trace element concentrations in lake water with respect to riverine one is due to trace element migration in the form of complex organic compounds: long water residence time in lake favors to organic compounds decay by means of microbial- and photo-degradation followed by metal precipitation.

Abstract:

A specially designed high resolution ICP-MS was combined with an ultrasonic nebulizer to analyze trace amounts of various inorganic contaminants contained in water samples. It was confirmed that the detection limits of most elements obtained by the proposed method were well under 1 ppt. The Standard Reference Material 1643b (trace elements in water) provided by NIST (National Institute of Standards and Technology, formerly U. S. National Bureau of Standards) was also analyzed. Concentration values obtained by this work were in good agreement with certified values for all the elements examined except for Cu. It can be concluded from the foregoing that the combination of the above two instruments materializes an extraordinarily sensitive method and paves the way for direct determination of a considerable number of trace and ultra-trace elements in water samples with acceptable speed and accuracy.

Full text

Abstract:

Models that describe the trace element status formation in the human organism are essential for a correction of micromineral (trace elements) deficiency. A direct trace element retention assessment in the body is difficult due to the many internal mechanisms. The trace element retention is determined by the amount and the ratio of incoming and excreted substance. So, the concentration of trace elements in drinking water characterizes the intake, whereas the element concentration in urine characterizes the excretion. This system can be interpreted as three interrelated elements that are in equilibrium. Since many relationships in the system are not known, the use of standard mathematical models is difficult. The artificial neural network use is suitable for constructing a model in the best way because it can take into account all dependencies in the system implicitly and process inaccurate and incomplete data. We created several neural network models to describe the retentions of trace elements in the human body. On the model basis, we can calculate the microelement levels in the body, knowing the trace element levels in drinking water and urine. These results can be used in health care to provide the population with safe drinking water.

Abstract:

The article highlights the results of the research content of mobile forms of certain trace elements in the water for watering sheep, pasture soils and feed of «Radvan Nowa» farm, Beregy village, Pustomyty district, Lviv region. The aim of research was to examine the actual content of certain trace elements (Cu, Fe, Mn, Zn, Co, Pb, Ni, Cd), determine the deviation of studied mobile forms of trace elements from the maximum permissible concentration (MPC) and to establish the suitability of soil and water in the area for livestock. Also determine the trace elements availability of feed on the farm. Reseived results indicate that the water in this sector meets sanitary standards for the content of trace elements studied and can be used for watering sheep without any reservations and ground land suitable for future use and livestock. The content of trace elements in the soil – water – feed on the «Radvan Nowa» farm, Pustomyty district, Lviv region is the insufficient level that makes it impossible to use the available forage in feeding sheep without further introduction of corrective diet supplements and premixes. The lowest content in the feed was Copper, discovered that in the rough and succulent feed was at an availability of 21.1% from the norm, and in grain feed grain – 6.5% of normal. The highest level of availability of feed was Zinc, observed that in the rough and succulent feed average content 61.8% of normal and the grain was at 76.4%. Further findings will be used to correct diets and explore new trace element supplements for lambs for fattening in the summer.

Abstract:

Mine water contains trace heavy metals which are some essential trace elements in high concentrations causing the pollution of nearby water bodies, related ground waters and soils degradation. The aim of the study is to identify and quantify the essential trace elements present in the different mine water samples and their level of toxicity. Digestion technique was employed to pretreat the mine wastewater before analysis. Physicochemical analysis was conducted for pH, electrical conductivity (EC), total dissolved solids (TDS), and salinity. The samples collected from four different locations are Sample A (Gold mine), Sample B (Copper mine), Sample C (Iron mine), Sample D (Tin mine). The raw or untreated mine water samples were analyzed using inductively coupled plasma optical emission spectroscopy (ICP-OES). The results showed the essential trace elements present in all the mine water samples are Mn, Cu, Fe and Zn. Cu is highly concentrated in copper (73.87 mg/L) and tin (2.09 mg/L) mine water while Fe is dominant in water samples collected from gold (7.19 mg/L) and iron (13.12 mg/L) mine. In conclusion, the essential trace elements Mn, Cu, and Fe present in all the mines are very high and can be harmful to human life in the environment but the concentrations of Zn in the entire mine water samples are within the permissible level of standard drinking water and hence it can pose no threat to human life.

Abstract:

Exposure to toxic concentrations of trace elements in rice and drinking water is a serious issue for millions of South Asians, due to rice serving as a large portion of their diets and the geochemical enrichment of trace elements in groundwaters. The overall goal of this study was to evaluate and compare the hazards posed from toxic trace elements through the consumption of commercially available basmati rice and public drinking water sources across Lahore, Pakistan. Drinking water samples (n = 36) were collected from publicly accessible drinking taps from eight administrative towns and the cantonment. Rice samples were obtained from 11 markets (n = 33) across Lahore between December and February 2022–2023. Market rice concentrations exceeded the World Health Organization’s (WHO) limits and the Total Hazard Quotient (THQ) values exceeded 1.0 for As, Cu, and Pb, thus indicating multielement contamination. Market rice trace element concentrations and price were not correlated. As, Se, and U concentrations in drinking water were above the WHO’s drinking water guidelines and had THQ values exceeding 1.0, showing multielement contamination. Cr, Se, and U concentrations in drinking water were greater for impoverished administrative towns compared to middle and wealthy administrative towns, highlighting socioeconomic inequities in exposure to hazardous concentrations. We conclude that the citizens of Lahore are exposed to rice and drinking water that are hazardous to human health, including As and other lesser studied trace elements.

Abstract:

Trace elements are rarely distributed in earth's crust and they are invariably in low concentrations. Due to this low concentration they are not analyzed by conventional hydrochemical methods but by rather special techniques with great care. The trace elements are especially useful in detecting the origin of the groundwater in an area. Their regional distribution helps to obtain significant clues on the groundwater movement and mixture processes. It is proposed, herein to assess the trace element concentration available at far distant points by employing the cumulative semivariogram models. These models furnish further systematic interpretations about trace element areal extends, concentration directions, groundwater movement and its continuity.

Abstract:

There are more than 70 chemical elements in the human body. To date, the need for more than 20 trace elements has been determined: deficiency in them leads to disruption of the neural, immune and endocrine regulation and adaptive potential, increases the risk of infectious diseases and development of their chronicity. A prolonged absence of certain nutrients in the diet, or vice versa, excess of them in soil and water, can cause irreversible changes in the body. The article discusses physiological role of minerals, macro and micronutrients, features of their metabolism, content standards, causes of their shortage in the diet. Recommendations on the choice of material for the study of the trace element composition are given and possibilities of modern laboratory diagnostics are presented.

Concentration and accumulation of seven trace elements (Cd, Cu, Pb, Ni, Fe, Mn and Zn) were measured in water (dissolved and particulate) phase, sediment and two species of aquatic plants phragmits australis and Ceratophylum demerssum collected during summer season, 2012 from the main outfall drain, some environmental parameter (Temperature, dissolved oxygen, salinity, pH) of water were measured, also total organic carbon TOC%, sediment texture were measured and expressed as percentage. Higher concentration of elements under study were observed in sediment more than their concentrations in water and plants, while particulate phase of water concentrated trace elements more than their concentration in dissolved phase, whereas the accumulation of trace elements in plants, showed that their concentration in phragmits australis was more than their concentration in Ceratophyllum demerssum. The study observed that it can use the two species of plants as bioindicator for accumulation of trace elements also the concentration of TE in the study samples were in acceptable range, when it compared with world wide range. The study showed that the possibility of using both plants to remove this type of pollutant from the aquatic environment and can be used in bioremediation for processes.

Abstract:

A study was carried on an area polluted by oil in Oman to determine the mobility of trace elements during each step of an ex-situ treatment process. Quality of groundwater following an air flotation treatment was investigated and discussed. About 15 water samples were collected from 7 monitoring wells which are under air sparging treatment for remediation of oil contamination in Al Batinah region (Northeast of Oman). Chemical composition of groundwater during and after the treatment was compared with chemical composition of groundwater before any treatment. Water samples were also collected from different monitoring wells in the same area. The investigated elements consist in Na, Mg, Ca, K, Fe, Cr, Ni, Cu, Zn, Ag, Cd, Sr, Ba, Pb and rare earth elements (REEs). Chemical composition of trace and major elements during each step of treatment revealed that Ni, Zn, Cu and Al have been increased relative to untreated water contrary to Ag which decreased. Major elements and Cr, Pb, and Cd remain unchanged during the treatment process. The REEs were significantly depleted during the last step of treatment relative to the raw water but their distribution did not reveal any fractionation. Trace elements such as Zn, Cu, Ni show an increase and Ag and REES a decrease relative to raw water before any treatment. For treatment of groundwater, chemical investigation of different agents used during the treatment and the speciation of each key trace elements should be investigated at each step of treatment procedure.
