“…Their long half-life and ability to accumulate in tissues increase their toxicity. Lead, cadmium, and mercury poisoning have serious consequences, and long-term exposure to low metal doses leads to chronic poisoning (8). Their mutagenic, carcinogenic, embryotoxic, and teratogenic effects may be visible even after the source of exposure has been eliminated.…”

The aim of the study was to determine the concentrations of lead (Pb), cadmium (Cd), and mercury (Hg) in the liver, kidneys, and muscles of European beavers (Castor fiber) and thus to evaluate the degree of heavy metals contamination in Warmia and Mazury region in Poland. The study was conducted on free-living beavers captured in region of Warmia and Mazury during autumn 2011. Concentrations of the elements were determined by atomic absorption spectrometry. The presence of the metals was detected in all individual tissue samples. Mean Pb and Hg concentrations were relatively low. However, the high mean Cd level, especially in the kidneys (7.933 mg/kg) and liver (0.880 mg/kg) was demonstrated. Despite the fact that region of Warmia and Mazury is considered to be "ecologically clean", the conducted studies indicate that systematic monitoring for the presence of heavy metals is necessary not only in industrialised but also in agricultural regions, as well as in natural ecosystems.

“…Cadmium is a very toxic metal, and also an environmental and industrial pollutant which is present in soil, water, air and food (Cinar, 2003;Kaplan et al, 2011). This metal enters surface water from the industrial wastes and found in soil by leaching of sewage sludge through soil (Joshi and Bose, 2002).…”

Our study pertains to the potential ability of vitamin C and/or vitamin E, used as nutritional supplements, to alleviate oxidative stress induced by cadmium. Male rats were randomly divided into five groups of eight each. Group I served as the controls; group II received in their drinking water CdCl 2 (200 mg/L); group III received both CdCl 2 and vitamin C (1.5 g/L of water); group IV was treated with CdCl 2 and vitamin E (400 mg/kg diet); and group V received CdCl 2 + vitamin C + vitamin E. The exposure of rats to cadmium chloride for 30 days resulted in a significant decrease in body weight gain. Cadmium treatment also produced oxidative liver injury characterized by increasing serum glucose concentration, glutamate-pyruvate transaminase (GPT), alanine aminotransaminase (GOT) and alkaline phosphatase (ALP) activities. Meanwhile cadmium supplementation decreased serum total protein and albumin in animals. In addition, liver glutathione level, catalase and glutathione peroxidase (GSH-Px) activities were diminished. With vitamin C and vitamin E administration during intoxication of cadmium, corrective effects on Cd-induced oxidative stress in the liver was observed. In conclusion, this study demonstrates that oral exposure to Cd caused reduction in LPO and antioxidant enzyme activities in rat's liver, and vitamin C or vitamin E may have partial ameliorative effects on these disturbances, whereas vitamin C and vitamin E together assured a more efficient protection of the organ against the noticed oxidative stress.

Concentrations of eight elements were measured in Chelonia mydas and Lepidochelys olivacea eggs collected along the Pacific coast of Panama. Manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), and mercury (Hg) concentrations were similar to previous reports of these species from around the world, while lead (Pb) was lower than previous reports. Cd posed the highest health risk to people who regularly eat the eggs, with average consumption rates leading to target hazard quotients (THQ) of up to 0.35 ± 0.15. Our conclusions indicate that current turtle egg consumption in isolated, coastal Pacific communities may pose a health concern for young children, and that youth and young adults should limit their consumption of turtle eggs to reduce their total intake of nonessential metals.
