ABSTRACT

The detection of heavy metal residues viz., copper, lead and zinc was carried out by FAAS techniques in fish, water and sediment collected from Seabass culture pond and sea costal area near to Soil Salinity Research Center, NAU, Danti (Dist. Navsari). The order of concentration of heavy metals in Seabass fish in the present study was Zn>Cu>Pb. The study revealed that average values for Cu, Pb and Zn in fish samples observed were 0.101 ± 0.044, 0.025 ± 0.005, and 15.191 ± 1.604 ppm, respectively, whereas in fish liver samples, the values were reported as 0.470 ± 0.192, 0.040 ± 0.007, and 15.670 ± 1.499 ppm, respectively. The average values of heavy metals in water and sediment samples observed were 0.320 ± 0.023 and 12.846 ± 1.110 ppm for Cu, 1.495 ± 0.147 and 14.700 ± 1.536 ppm for Pb and 0.011 ± 0.007 and 0.657 ± 0.197 ppm for Zn, respectively. The concentrations of Cu, Zn and Pb detected in fish were within the safe limits, so posing no public health problem in the Asian Seabass consumers.
