There has been increasing
awareness that sediment may serve as an important source for metal bioaccumulation in
aquatic animals (Luoma, 1989). For example, Cd associated with the sediment can
contribute up to 60–100% of the total Cd burden in sediment dwelling chironomidae
(Bendell-Young, 1999) or polychaete (Selck et al., 1998, 1999; Wang et al., 1999).
