| Trace elements in tissues of wild carnivores and omnivores in Croatia | |
| 2012 Bulletin Environment Contamination and Toxicology (88): 94-99 | |
The differences in metal exposure (As, Cd, Cu, Pb and Hg) in the muscle, liver and kidney tissues of brown bears (_Ursus arctos_), grey wolfs (_Canis lupus_), Eurasian lynxs (_Lynx lynx_), Eurasian badgers (Meles meles) and pine martens (_Martes martes_) from Croatia were observed. The highest mean Cd levels were found in kidney and liver of Eurasian badger (3.05 and 0.537 mg/kg). The highest Cu concentrations (mg/kg) measured in liver tissue were obtained in order: Eurasian badger (15.2)[brown bear (12.1)[pine marten (10.3)[Eurasian lynx (8.43)[grey wolf (6.44). Result presented that Eurasian badger accumulated the highest levels of elements: As, Cu and Pb in muscle; As, Cd, Cu and Pb in liver; Cd and Pb in kidney. Kidney of pine marten accumulated the highest concentrations of As, Cu and Hg. Omnivorous species observed present an important bioindicator for the accumulation of toxic elements indicating an enhanced vulnerability for response to ecological changes in forested terrain. Generally, element concentrations found in five species observed were lower in comparison to levels reported in previous studies and below levels related to toxicosis in mammals. |
