Animal hair is a useful biomonitoring tool for assessing the occurrence of trace elements in ecosystems. Essential (chromium, copper, iron, manganese, nickel, and zinc) and nonessential (aluminum, arsenic, cadmium, mercury, lead, palladium, platinum, rubidium, tin, and vanadium) elements were investigated in hair of badger (Meles meles), wild boar (Sus scrofa), marmot (Marmota marmota), wolf (Canis lupus), fox (Vulpes vulpes) and deer (Cervus elaphus) from Northwestern Italy. Badger was found to be the highest bioaccumulator of metals, while wolf, fox and deer recorded the lowest values. Essential elements contribute in higher degree to the sum of metals for all species except for wild boar. Results have shown that animals with omnivorous diet such as badger, marmot and wild boar have metal content (especially Al, As, Cr, Cu, Fe, Ni, V) higher than carnivores (wolf and fox) and herbivores (deer) and could represent an effective sentinel of environmental exposure to metals.
动物毛发是评估生态系统中微量元素存在情况的有用生物监测工具。本研究调查了来自意大利西北部的獾（Meles meles）、野猪（Sus scrofa）、旱獭（Marmota marmota）、狼（Canis lupus）、狐狸（Vulpes vulpes）和鹿（Cervus elaphus）毛发中的必需元素（铬、铜、铁、锰、镍和锌）和非必需元素（铝、砷、镉、汞、铅、钯、铂、铷、锡和钒）。结果表明，獾是金属元素的最高生物累积者，而狼、狐狸和鹿则记录到最低值。除野猪外，所有物种的金属元素总和中必需元素的贡献程度都较高。结果表明，杂食性动物（如獾、旱獭和野猪）的金属含量（尤其是 Al、As、Cr、Cu、Fe、Ni、V）高于肉食性动物（狼和狐狸）和草食性动物（鹿），它们可以作为金属环境暴露的有效哨兵。
