Biaccumulation of Sediment-Bound Heavy Metals in Grey Mullet, Liza macrolepis

摘要

Two groups of grey mullet, Liza macrolepis, a filter and a detritus-mud feeder, were chosen as the subjects of a sediment exposure experiment for evaluating the bioac- cumulation of toxic metals associated with the Kaohsiung- harbour sedimental contamination. After 180 days of sediment exposure, the sediment treated group showed significantly elevated Cu, Mn, Fe, Zn and Cd concentra- tions in whole fish at 3-, 1.5-, 3-, 2-, and 2-times, re- spectively, higher than the control group.
