Concentrations of Chromium (Cr), Cadmium (Cd), Copper (Cu), Iron (Fe), Magnesium (Mg), Manganese (Mn), Nickel (Ni), Cobalt (Co), Zinc (Zn) and Aluminium(Al) were determined in four edible part of the marine fish species (Nematolosa nasus, Aleper para, Atropus atropus and Parastromateus niger) from Parangipettai Coast, south east coast of India in September 2008 to understand the toxicity of such heavy metals. Heavy metal concentrations were measured using Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES). Concentrations of the heavy metals in examined fish species ranged as follows: Cr 0.65-0.92; Cd 0.18-0.54; Cu 0.12-0.31; Fe 24.1-50.3; Mg 0.54-1.21; Mn 0.31-1.20; Ni 0.38-1.54; Co 0.05-0.28; Zn 14.1-33.5 and Al 14.1-33.5μg/g. Cd concentration increases gradually as weight and length of the fish increases. Heavy metals in the edible parts of the investigated fish were in the permissible safety levels for human uses.
