This study presents concentrations of heavy metals (iron, zinc, manganese, copper, lead, and cadmium) in livers of three owl species from Korea. Essential trace elements (iron, zinc, manganese, and copper) did not differ among the owl species. We suggest that the essential elements are within the normal range and are maintained by normal homeostatic mechanisms. Lead and cadmium concentrations in Eurasian Eagle Owls (Bubo bubo) were significantly lower than in Brown Hawk Owls (Nixos scutulata) and Collared Scops Owls (Otus lempiji). Lead and cadmium concentrations in Korean owl species were at background levels; lead concentrations in two Collared Scops Owls were above background concentrations. Lead and cadmium concentrations were similar to concentrations previously reported in owls from other parts of the world. We suggest that lead and cadmium concentrations in Korean owls are below toxic concentrations.
本研究展示了来自韩国的三种猫头鹰肝脏中的重金属（铁、锌、锰、铜、铅和镉）浓度。必需微量元素（铁、锌、锰和铜）在猫头鹰物种之间没有差异。我们认为这些必需元素处于正常范围内，并通过正常的稳态机制维持。雕鸮（Bubo bubo）体内的铅和镉浓度显著低于褐鹰鸮（Nixos scutulata）和领角鸮（Otus lempiji）。韩国猫头鹰物种体内的铅和镉浓度处于背景水平；两只领角鸮体内的铅浓度高于背景浓度。铅和镉浓度与世界其他地区猫头鹰先前报告的浓度相似。我们认为韩国猫头鹰体内的铅和镉浓度低于有毒浓度。
