Cadmium, copper, iron, and zinc levels were measured in the kidneys of 115 grey wolves (Canis lupus) from Idaho, Montana and Alaska (United States), and from the Northwest Territories (Canada). No significant differences in the levels of iron or copper were observed between locations, but wolf kidneys from more northern locations had significantly higher cadmium levels (Alaska > Northwest Territories > Montana ≈ Idaho), and wolves from Alaska showed significantly higher zinc than other locations. Additionally, female wolves in Alaska had higher iron levels than males, and adult wolves in Montana had higher copper levels than subadults.
镉、铜、铁和锌水平在来自美国爱达荷州、蒙大拿州和阿拉斯加以及加拿大西北地区的 115 只灰狼（Canis lupus）的肾脏中进行了测量。在不同地点，铁或铜的水平没有显著差异，但来自更北部地区的狼的肾脏中镉水平显著更高（阿拉斯加>西北地区>蒙大拿≈爱达荷），并且来自阿拉斯加的狼的锌含量显著高于其他地区。此外，阿拉斯加的雌性狼的铁含量高于雄性，蒙大拿的成年狼的铜含量高于亚成年狼。
