Abstract

A bio-monitoring study was performed to investigate certain metals (cadmium, cobalt, copper, iron, magnesium, manganese, nickel, lead, zinc, aluminium and boron), using Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) for the assessment of the present status in the two coastal ecosystems and compiling the baseline data for future monitoring. Tissue samples of fishes have different level of accumulation viz, Cd = 0.07-0.40, Co = 0-0.32, Cu = 0.53–0.39, Fe = 1.42–8.12, Mg = 9.74–33.1, Mn = 0.08–0.84, Ni = 0.01–0.97, Pb = 0.12–2.05, Zn = 0.81–2.11, Al = 1.26-3.98, Cr = 0.25-1.76 and B = 0.17-1.87 µg g -1 dry wt. respectively. The rate of metal accumulation higher in species (Thalassoma trilobatum and Saurida tumbil). Concentration of toxic metals such as Cd and Pb were well above the permissible limits proposed by the World Health Organization and Food and Agricultural Organizations.
