Bioaccumulation of heavy metals in aquatic animals collected from coastal waters of Gresik, Indonesia

A survey of the presence of metals in aquatic animals caught from Gresik coastal waters, Indonesia, has been conducted. The results show that all animals contained Zn levels higher than the level of other metals (As, Cd, Cr, Ni, Cu, Se and Pb) in the same species. The copper level recorded in tissue of banana shrimp showed higher copper concentration than that in other fishes. The concentration of Zn in whole body of animals (ponyfish and anchovy) was relatively higher than those recorded in muscle tissues (banana shrimp, drum, mullet and sea catfish). It was also found that the level of metals in all samples collected from this area contained metals in their tissue within acceptable range for consumption. These data provide useful information for future reference.
