Concentrations of organochlorine persistent pollutants were investigated in tissues of the European hedgehog (Erinaceus europaeus). Road kills and carcasses from wildlife rescue centers were used to characterize organochlorine compound tissue distribution and tissue profile dissimilarities (hair, liver, kidney, muscle, and adipose tissue). The most important contaminants were polychlorinated biphenyls (PCBs), chlordanes (CHLs), and DDTs, with median concentrations of 75, 5.1, and 1.4 ng/g liver wet weight, respectively. Median levels for the remaining compounds-hexachlorobenzene (HCB), hexachlorocyclohexanes (HCHs), and octachlorostyrene-were less than 0.5 ng/g liver wet weight. Compared to results with other mammalian wildlife, the present results indicate that hedgehogs may accumulate considerable concentrations of organochlorine compounds. Polychlorinated biphenyls and HCB preferably accumulated in liver and muscle tissue. Concentrations of DDTs and HCHs were highest in muscle tissue and hair, respectively. Octachlorostyrene and CHL levels were predominant in liver. The observed positive relationships between concentrations in hair and internal tissues for PCBs, DDTs, HCB, HCHs, and CHLs (0.49 < r < 0.91) and for several individual PCB, DDT, and CHL compounds (0.31 < r < 0.76) indicate the usefulness of hair as a biomonitoring tool of organochlorine compounds. Multivariate profile analyses revealed a higher dominance of less-persistent compounds (p,p'-DDT, alpha-HCH, and PCBs 95, 101, and 149) in hair compared to internal tissues. The present study demonstrates the suitability of hedgehog hair as a nondestructive biomonitoring tool regarding pollution with organochlorine compounds and the promising role of the hedgehog as a mammalian indicator species of pollution in terrestrial environments.
对欧洲刺猬( Erinaceus europaeus )组织中的有机氯持久性污染物浓度进行了调查。利用道路死亡动物和野生动物救助中心的尸体来表征有机氯化合物的组织分布和组织特征差异(毛发、肝脏、肾脏、肌肉和脂肪组织)。最重要的污染物是多氯联苯(PCBs)、氯丹(CHLs)和滴滴涕(DDTs),肝脏湿重中的中位数浓度分别为75、5.1和1.4 ng/g。其余化合物——六氯苯(HCB)、六氯环己烷(HCHs)和八氯苯乙烯的中位数水平低于0.5 ng/g肝脏湿重。与其他哺乳动物野生动物的结果相比,目前的结果表明刺猬可能积累了相当浓度的有机氯化合物。多氯联苯和六氯苯在肝脏和肌肉组织中积累较多。滴滴涕和六氯环己烷的浓度分别在肌肉组织和毛发中最高。八氯苯乙烯和氯丹水平在肝脏中占主导。观察到毛发和内部组织中多氯联苯、滴滴涕、六氯苯、六氯环己烷和氯丹浓度之间的正相关关系(0.49 < r < 0.91)以及几种多氯联苯、滴滴涕和氯丹单一化合物之间的正相关关系(0.31 < r < 0.76),表明毛发作为有机氯化合物生物监测工具的实用性。多变量特征分析显示,与内部组织相比,毛发中持久性较低的化合物(p,p'-滴滴涕、α-六氯环己烷以及多氯联苯95、101和149)占主导地位更高。本研究证明了刺猬毛发作为有机氯化合物污染的非破坏性生物监测工具的适用性,以及刺猬作为陆地环境中污染的哺乳动物指示物种的潜在作用。
