The presence of algal particles
had little influence on metal assimilation from ingested sediment, and conversely, the presence of
sedimentary particles had little effect on metal assimilation from ingested diatom (except for Cd in
the mussels). In the mussels, AEs were higher from oxic sediment than from anoxic sediment by
3.13 for Cd, 2.03 for Cr, and 1.43 for Zn, and in the clams AEs were higher from oxic
sediment by 2.83 for Cd, 2.03 for Cr, and 2.03 for Zn. Our study suggested that metals
associated with anoxic sediment can be potentially available to marine bivalves, and that metal
AEs determined for a single diet were probably not affected by the presence of other food
particles. Ó 2000 Elsevier Science B.V. All rights reserved.
