Abstract
The availability of a number of metals to epipelic diatoms and meiofauna was investigated by comparison with the total (aqua regia extractes) and bioavailable (acetic acid extracted) metal concentrations and the proportion of bioavailable metal for evidence and metal accumulation. Both total and bioavailable metal sediment concentrations strongly correlated with chromium nickel and zinc tissue levels.
Accumulation of chromium and zinc by meiofauna from dietary sources was suggested by comparison with levels in the epipelic diatom fraction.
The results highlight the problem in assessing metal concentrations in environmental samples but indicate that metal levels in food may be more important that availability of metals in sediments for the accumulation of some metals.
