Abstract
Rates of lead accumulation from contaminated food sources were examined for the fresh-water gastropods,Physa integra andCampeloma decisum. Lead was slowly accumulated fromaufwuchs (0.52–0.87 Μg Pb/g dry wt of tissue/day) by the grazing snail,P. integra while no statistically significant lead accumulation from sediments was noted in the deposit/suspension feeder,C. decisum. Aufwuchs-associated iron and manganese did not affect the bioavailability of lead.
