In the present study Clarias batrachus was exposed to sublethal concentrations (~10% of 96 h- LC50) of mercury (0.080ppm) and chromium (10.2ppm) were investigated for 28 days under laboratory conditions. The concentrations of these metals in the various organs were detected through Inductively Coupled Plasma__ampersandsignndash;Atomic Emission Spectrometer (ICP-AES). The concentration of mercury was high in brain (656.82ppb) followed by gills (287.63ppb), liver (229.64ppb), kidney (176.44ppb) and muscles (49.21ppb) where as in the fishes exposed to chromium, the concentration was high in gills (315.21ppb) followed by liver (241.4ppb), kidney (187.96ppb), brain (128.29ppb) and muscles (51.3ppb).The ability of mercury and chromium as toxicants was proved in the present study as the concentrations was found to be high in brain and gills respectively.
