Levels of organochlorine pesticides and polychlorinated biphenyls in the critically endangered Iberian lynx and other sympatric carnivores in Spain

摘要: Accumulation of organochlorine compounds is well studied in aquatic food chains whereas little information available from terrestrial chains. This study presents data levels tissue and plasma samples 15 critically endangered Iberian lynx (Lynx pardinus) other 55 wild carnivores belonging to five species three natural areas Spain (Donana National Park, Sierra Morena Lozoya River) explores their relationship with diet. The lynx, a diet based on the consumption rabbit, had lower PCB (geometric means, plasma: <0.01 ng mL(-1), liver: 0.4ngg(-1) wet weight, fat: 87 g(-1)lipid weight) than more anthropic opportunistic foraging behavior, such as red fox (Vulpes vulpes; 1.11 459 g(-1), 1984 g(-1)), or diets including reptiles at higher proportion, Egyptian mongoose (Herpestes ichneumon; 7.15 216 540 common genet (Genetta genetta; 466 3854 g(-1)). Chlorinated pesticides showed interspecific variations similar PCBs. Organochlorine have declined since 80s Donana but are still concern Eurasian otters (Lutra lutra; 3873-5426 g(-1)) industrialized region Madrid.
