Concentrations of heavy metals and PCBs in the tissues of European beavers (Castor fiber) captured in northeastern Poland
Abstract
European beavers (Castor fiber) from two regions were examined to identify exposure to persistent environmental contaminants. A reference group was comprised of six animals from the Forest Division of Srokowo, and an exposed group was comprised of five animals from the vicinity of a former military airport operated in 1918–1986—both from Warmia land in Poland. 137 Cs in beavers' muscles was considered negligible for the overall condition and reproduction of the animals. Elevated levels of Cd and Pb occurred in the kidneys and liver of beavers from a former military airport area. dl-PCBs were found in the liver of all specimens, and pCB no. 118 was a dominant compound. Beavers as animals living both in water and land habitats can be good bioindicators of heavy metal environmental pollution caused by human activity. Despite the significant contamination of former military sites in northeastern Poland, the beaver population shows an upward trend, reflecting the excellent adaptation of this species to a changing environment
