The aim of the study was to determine concentration of macroelements (P, Ca, Mg, Na, K), and some microelements, including toxic heavy metals (Cr, Fe, Mn, Zn, Cu, Co, Pb, Cd and Hg) in milk of Jersey cows. Milk samples were collected from Jersey cows kept in tie-stall barn in Greater Poland Province. The feeding was based on total mixed ration mixture. The maximum permitted level of Pb concentration in raw milk (0.02 mg/kg wet weight)was significantly exceeded (0.063±0.035 mg/dm3). The content of Hg was very low (0.106±0.057 μg/dm3).Significant (P£0.05) Spearman coefficient correlations were observed between contents of some elements in milk. Especially interesting were positive correlations of heavy metals: Cd-Cr, Co-Mn, Cr-Zn, Mn-Zn. Additionally the content of Ca was positively correlated with numerous elements: Hg, Cr, Cu, Mn, Zn, Mg, and negatively correlated with the content of Fe.

In the samples of sediment accumulated in the reservoir Zadębie and ground from the its bottom the contents of the As, Ba, Cr, Cd, Co, Cu, Hg, Mo, Ni, Sn, Sr, V, Zn and Ca, Fe, Mg, Mn, S, P, and TOC were determined. The content of mineral oil, 17 PAHs compounds, 7 PCB congeners and 20 organochlorine pesticides were determined as well. Sediment accumulated in the reservoir is characterized by very low contents of trace elements similar to the geochemical background values. Slightly increased content of Ba, Zn, Cu, Cr, Pb and Hg were observed in the northern part of the basin. There was a significant increase in the content of mineral oils and PAHs in sediments accumulated compared to their content in the bedding layer. Among the analyzed organochlorine compounds were detected only isomer of α-HCH and p,p′-DDT and its metabolites.

Elements In Rainwater

<p>Rainwater is considered as a dependable potable and non-potable water source, used for domestic purposes as well as for human consumption in many cases. While it is usually believed that rainwater is safe for drinking purposes, many studies have explored the existence of trace metals in harvested rainwater, which can impose a serious health risk to human beings when present in relatively high concentrations. The concentration of trace elements in atmospheric precipitation including rainwater also provides a good indication of the environmental pollution caused by anthropogenic activities.</p><p>Chattogram, located in the south-eastern side of Bangladesh, is the busiest port city and the second-largest city in the country with a population of around 4.5 million people. With the presence of high salinity and arsenic in groundwater and poor quality of surface water in the region, rainwater harvesting is the most sustainable solution to be considered in the water system management for the area, particularly given annual mean precipitation of 2488 mm during the rainy season. In recent years, extensive studies have been carried out on the potential application of different rainwater harvesting systems across the region, but there have been very few studies devoted to the identification of the composition of trace elements in rainwater considering site-specific influences in the trace metal distribution in the rainwater.</p><p>The purpose of this study was to investigate the composition and source appointment of trace metals (Fe, Cu, Zn, Pb, Mn, Cr, and Cd) in rainwater in the south-eastern region of Bangladesh. To determine their sources and relative contributions in rainwater, a total of ninety-five rainwater samples were collected in this study from five different locations representing different land-use patterns (industrial, commercial, urban, and sub-urban) within the study area, from June 2018 to October 2019. The collected water samples were analyzed for Fe, Cu, Zn, Pb, Mn, Cr, and Cd using Atomic Absorption Spectrophotometer maintaining standard protocols. The measured trace elements from the collected rainwater samples were then compared with the WHO and Bangladesh drinking water standards.</p><p>The resulting concentration of trace metals in this study was found within the allowable limits in accordance with WHO and Bangladesh drinking water standards, confirming the suitability of rainwater as a potable water source for human consumption. The average concentration of trace metals in rainwater was found in the order of Zn ˃ Cu ˃ Fe ˃ Cr ˃ Mn ˃ Pb ˃ Cd for the tested samples. Overall, the trace metal concentrations of Cu and Zn were predominantly observed in rainwater samples collected from the industrial area, indicating the influence of anthropogenic activities on atmospheric pollution. The concentrations of the trace elements in this work were found to be overall higher when compared to those reported in other investigations around the world. The measurements of this study would provide an indication of atmospheric pollution in rainwater caused by the anthropogenic origins of trace metals as well as provide a database of trace metals in rainwater for further relevant research studies across the country.</p>

The present study focused on the physicochemical characterization and spectrophotometric determination of the concentrations of trace elements (Zn, Cu, Fe and Mn) and toxic heavy metals (Cd and Pb) in raw milk samples collected from various commercial sites of Peshawar city, Pakistan. Evaluation of the nutritional values as well as the possible health concerns associated with the consumption of contaminated milk shown the average percentage composition of protein, fats, solid non-fats, lactose, salts and added water in the milk sample as 2.78, 4.81, 6.41, 3.05, 0.47 and 31.1 %, respectively. The values of pH, conductivity, density and freezing point were observed as 6.59, 3.51 mS/cm, 1.04 g/mL and -0.3674 ºC at 26 ºC. The physicochemical characteristics such as percentage protein, fat, lactose, salts, water, solid not fat, total solids, pH, conductivity and density were evaluated and found in the safe limits of the WHO/FAO. The average concentration of trace elements such as zinc and copper were found to be 1.4035 mg/L and 0.2588 mg/L, respectively. The concentration of Zn and Cu was found within permissible limits suggested by WHO. However, the average concentration of Fe, Mn, Cd and Pb were found higher than the permissible limits of WHO. The observed concentrations were: Fe = 1.5553, Mn = 0.4354, Cd = 0.1865 and Pb = 1.1162 mg/L. The presence of the non-essential and hazardous Cd and Pb in milk samples even in lower concentrations may cause severe health problems since these are the most noxious pollutants due to their non-biodegradable and bio-accumulative nature. Over-dose of Fe and Mn also leads to several health issues. A thorough and more precise investigation of raw milk consumption in Peshawar is highly recommended to ascertain the actual reasons and sources in the larger public interests.
