Lead levels in small mammals were studied in 6 areas -- 3 associated with highways of different traffic densities, and 3 control sites in forested areas. Lead levels were also studied in insects from 2 traffic areas and in earthworms from different distances from 2 traffic areas. Lead levels were low in insects ranging from 3.84 microng/g to 3.35 microng/g. Lead levels in earthworms were highest in those recovered closest to highways and from the area with the higher traffic volume. Lead levels in mammals generally was highest in mammals from areas of higher traffic densities. Higher levels of lead were found in shrews than in Peromyscus and Microtus.
在6个区域对小型哺乳动物的铅含量进行了研究，其中3个区域与不同交通密度的公路相关，另外3个是森林地区的对照点。还对来自2个交通区域的昆虫以及距2个交通区域不同距离的蚯蚓的铅含量进行了研究。昆虫的铅含量较低，范围在3.84微克/克至3.35微克/克之间。蚯蚓的铅含量在离公路最近且交通流量较大的区域采集的样本中最高。一般来说，交通密度较高地区的哺乳动物体内铅含量最高。鼩鼱体内的铅含量高于鹿鼠和田鼠。
