The wild boar (Sus scrofa) is becoming more common in Europe and has potential to be used as sentinel species for local contamination of heavy metals. Concentrations of nine trace elements (arsenic (As), cadmium (Cd), copper (Cu), iron (Fe), lead (Pb), magnesium (Mg), manganese (Mn), selenium (Se), and zinc (Zn)) were examined in kidney tissue of 104 female wild boars hunted at three sites in Sweden. The interrelationships between the trace elements and age dependency were investigated. Reproductive health was previously known to differ among animals at the different study sites, but could not be explained by heavy metal concentrations and no associations were found between heavy metals and reproductive parameters. Kidney concentrations of Cd (mean 4.16 mg/kg wet weight (w.w.), range 0.16–12.8) were higher than the permissible level for human consumption in 99.9% of the samples. Pb concentrations were generally intermediate or low (mean 0.14 mg/kg w.w., range 0.03–1.01) and exceeded the levels accepted for human consumption in 0.02% of the samples. Age class was significantly associated with the concentrations of Cd, Mg, and Mn. Concentrations of As were low (mean 0.02 mg/kg w.w., range <0.0001–0.08) and Cu and Se concentrations were within the ranges of suspected deficiency for 10% and 4% of the wild boars, respectively.

野猪（Sus scrofa）在欧洲变得越来越普遍，并且有潜力用作当地重金属污染的定点物种。九种微量元素（砷（As），镉（Cd），铜（Cu），铁（Fe），铅（Pb），镁（Mg），锰（Mn），硒（Se）和锌（Zn）的浓度））在瑞典三个地点被猎杀的104只雌性野猪的肾脏组织中进行了检查。研究了微量元素和年龄依赖性之间的相互关系。先前已知不同研究地点的动物之间的生殖健康有所不同，但不能用重金属浓度来解释，也没有发现重金属与生殖参数之间的关联。肾脏中的镉浓度（平均4.16 mg / kg湿重（ww），范围0.16-12.8）高于人类在99中允许的消费水平。9％的样本。铅的浓度通常处于中等或较低水平（平均值为0.14 mg / kg重量，范围为0.03–1.01），超过了0.02％的人类食用可接受水平。年龄类别与Cd，Mg和Mn的浓度显着相关。As的浓度很低（平均0.02 mg / kg ww，范围<0.0001-0.08），Cu和Se的浓度分别在10％和4％的野猪可疑缺乏范围内。
