“…Consuming food and water contaminated with copper may be harmful to the human body (Bennet-Chambers et al, 1999). Increased content of this element in the diet may lead to poisoning, a decrease in hemoglobin content, adverse metabolic changes, and also to liver, kidney, and heart damage (Kabata-Pendias and Pendias, 1999).…”

A study was carried out on 20 water bodies of the same origin in southern Poland. The study objectives included the assessment of toxic metal contamination in the bottom sediments of the water bodies in comparison with the geochemical background and sediments found in the substrate (i.e., vicinity) of the water bodies (i.e., the formations present in the surroundings of the water body itself), thus demonstrating the scale of anthropogenic enrichment of bottom sediments with toxic metals and assessing the cumulative impact on water bodies. The following amounts of toxic metals were found in the bottom sediments of the water bodies examined: 181.7-35200.0 ppm for zinc, 33.3-1648.8 ppm for lead, 1.8-359 ppm for cadmium, 14.0-271.5 ppm for copper, 45.3-167.5 ppm for chromium, and 12-128.5 ppm for nickel. Ratios of the values measured to the geochemical background were as follows: 0.7-135.9 (Zn), 0.6-53.0

Purpose Cadmium (Cd) is considered a toxic element and its concentrations are relevant to human health and the environment. Therefore, the purpose of the study was to determine the extent to which the bottom sediments of water bodies (artificial lakes and ponds) in the Silesian Upland in southern Poland are contaminated with Cd; an attempt was also made to determine the factors that condition spatial differences in the concentration of this element between individual water bodies in the region. Materials and methods Measurements of the Cd content in bottom sediments were carried out in 35 water bodies in southern Poland in 2011 and 2012. Depending on the surface area and morphometric characteristics, from two to nine samples representative in terms of sediment thickness were collected in each water body. Cadmium concentrations were determined for 92 0.25 g aliquots using the TD-ICP method. Results and discussion Cadmium content in all samples (0.7-580.0 mg kg ) and, with a few exceptions, was also higher than the preindustrial concentration (1.0 mg kg ) as the baseline for the geoaccumulation index (I geo ), the sediments examined can be classified as extremely and heavily contaminated (and moderately contaminated in a small number of cases). The assessment of sediment quality based on I geo, with the regional geochemical background (2.5 mg kg −1 ) adopted as the baseline, results in non-contaminated and moderately contaminated sediments being dominant with a far smaller number of heavily and extremely contaminated ones. Conclusions In the case of several water bodies, Cd concentrations were at record levels that have not been found anywhere else in the world. On the basis of the I geo , sediments of varying quality were found-from virtually uncontaminated to extremely contaminated. The I geo index as an indicator of the quality of bottom sediments is a measure that requires careful interpretation, especially when different concentration levels regarded as natural are used for determining its value.

“…Due to their concentrations and toxicities, Cd and Zn have been identified as the two metals of greatest concern in the area [1,[9][10][11]. Cadmium and zinc loadings that exceed natural background pose a potential problem for aquatic ecosystems and for humans [12]. The issue of contamination by these two metals is especially critical for coastal areas in which riverine and land-based inputs discharge into a semi-enclosed embayment, as in the Chinese Northern Bohai and Yellow Seas.…”

Abstract-Cadmium (Cd) and zinc (Zn) in surface water, sediment, carp, and crab samples collected from upstream and downstream regions of coastal watersheds along the Chinese Northern Bohai and Yellow Seas were analyzed to provide a comprehensive understanding and assessment of their environmental concentrations and bioaccumulations. The results showed that downstream waters contaminated with Zn would have adverse effects on aquatic organisms. Although nearly all sediments were contaminated with Cd due to human activities, little potential existed for Cd toxicity in sediment-dwelling fauna. Concentrations of Cd and Zn in most water, sediment, carp, and crab were less than published values. The downstream carp and crabs had higher mean bioaccumulation factors and biotasediment accumulation factors for Cd but lower mean biota-sediment accumulation factors for Zn than the upstream carp and crabs. Based on the relationships among Cd and Zn concentrations in water, sediment, and biota, the authors conclude that Cd and Zn in crabs primarily derived from sediment exposure. Although Cd and Zn in water and sediment originated from some of the same sources, the sources of Cd or Zn in water were likely different from those in sediment. Environ. Toxicol.
