Abstract

The results of this study suggest that simple chemical partitioning can explain the uptake of DDT and PCB residues in some benthic organisms, while biomagnification via dietary exposure is a more probable explanation for the concentrations of these contaminants found in muscle tissue of some higher trophic level pelagic organisms.
