title: Lead in shrimp Litopenaeus vannamei Boone in sublethal concentrations.
abstract: Determination of the accumulation and elimination of sublethal lead (Pb) in different shrimp tissues may be useful as an indicator of uptake and elimination characteristics of this metal. Aquaculture ponds are particularly influenced by Pb contamination, where aquatic animals may acquire the metal through adsorption to exoskeletons or gills from the surrounding water. Cationic Pb is accumulated preferentially in the nonedible fraction of shrimp, followed by exoskeleton, and to a minor extent in muscle. Lead contents in different tissues were lower than metal levels in exoskeleton. However, the presence of Pb in sediment due to purging may exert adverse consequences on shrimp as bottom feeders.
