| Abstract: | The bio-kinetics of lead in a benthic clam, Venus verrucosa were
investigated. Lead contents in various body organs of bivalves freshly
collected from contaminated coastal sites, and then after I month and 2 months
depuration, were investigated by anode stripping voltammetry. Histochemical
and secondary-ion emission spectroscopy techniques were employed to localize
lead at the cellular and subcellular levels. Most of the lead body burden was found to be sequestrated in the kidneys, presumably after entry through ingestion of lead contaminated particles and passage through the digestive gland. Some loss of lead to the gills was evident during the 2 month depuration period. Renal spherocrystals were found to be the most important subce11ular depositary sites for this contaminant. A likely transport mechanism of lead from one body organ to another is suggested. |
