Abstract
Concentrations of lead have been determined in three species of small mammal,
Sorex araneus, Clethrionomys glareolus and
Apodemus sylvaticus at roadside and control sites. The results are considered in relation to the lead content of the diet and the air, and it is concluded that the diet provides far the major pathway for lead exposure, even at the roadside site. Bone lead concentrations are found to be consistent with estimated lead exposure and metabolism.
