The present study evaluates the parasitological model constituted by the wood mouse (Apodemus sylvaticus) and its intestinal cestode (Skrjabinotaenia lobata) as a potential bioindicator of Cd and Pb in the urban dumping site of Garraf near the city of Barcelona (Spain) and in Begues (reference site). Tissues and respective S. lobata specimens of 38 wood mice captured in Garraf and Begues were analyzed for Cd and Pb by means of ICP-MS. Higher cadmium levels in S. lobata were found only in respect to the muscular levels of their hosts. Nevertheless, lead levels were 8.5-, 53.2- and 81.4-fold higher in S. lobata than kidney, liver and muscle levels of A. sylvaticus from Garraf, respectively. Thus, the proposed model seems to be a promising bioindicator to evaluate environmental lead exposure in terrestrial habitats. In addition, all available data on lead bioaccumulation by cestode parasites of terrestrial mammals are generally discussed.
本研究评估了以林姬鼠（Apodemus sylvaticus）及其肠道绦虫（Skrjabinotaenia lobata）构成的寄生虫学模型，作为西班牙巴塞罗那市附近加拉夫城市垃圾场以及贝格斯（参考地点）镉和铅的潜在生物指示物。通过电感耦合等离子体质谱法（ICP-MS）分析了在加拉夫和贝格斯捕获的38只林姬鼠的组织及其相应的S. lobata标本中的镉和铅。仅在S. lobata相对于其宿主肌肉水平方面发现了较高的镉含量。然而，来自加拉夫的S. lobata中的铅含量分别比林姬鼠的肾脏、肝脏和肌肉水平高8.5倍、53.2倍和81.4倍。因此，所提出的模型似乎是评估陆地栖息地环境铅暴露的一个有前景的生物指示物。此外，还对陆地哺乳动物绦虫寄生虫铅生物积累的所有现有数据进行了一般性讨论。
