Abstract

The metal levels (Hg, As, Cu, and Zn) in tissues of edible fish species (Pampus argenteus, Sillago sihama, Liza klunzingeri and Platycephalus indicus) were evaluated. The metal concentrations were found to follow the order: liver > kidney > gill > muscle, except for Zn from P. argenteus showing an inversion of liver and kidney. Generally, the benthic species (P. indicus and S. sihama) showed a marked potential for tolerating high metal levels. Significant negative correlations were found between fish size/age and metals concentration in the most organs. The element levels in the muscles were lower than the maximum allowable concentrations, except for mercury in S. sihama and P. indicus.
