Abstract

The levels of trace metals in surface water from the intertidal zone of ship breaking (Fouzdarhat, Madambibirhat and Kumira) and Halishahar (controlled zone) area, Chittagong were analyzed seasonally. The maximum concentration of Fe was found at Kumira varying from 65.710 to 67.900 µg ml-1 while the minimum was observed in Station-4 (0.119 to 0.122 µg ml-1). In case of Cu concentration, Fouzdarhat indicated the highest value ranging between 0.037 and 0.041 µg. ml-1. The lowest concentration of Cu was found in Halishahar (0.018 µg. ml-1) during pre-monsoon period. The level of Zn concentrations found in Fouzdarhat was twice the value observed in Halishahar. Cd concentrations were higher in Madambibirhat and Kumira in comparison with those at Halishahar. The concentration of different trace metals measured was found to be higher than the certified limit indicating deleterious effect on aquatic biota. However, concentrations of Pb were within the certified limit. The concentrations of trace metals in Halishahar (Controlled zone) were lower compared with those at ship breaking area. Besides, there were minimal seasonal fluctuations of trace elements observed in the studied four Stations. As per analysis and subsequent determinations the ship breaking area has been indicated as polluted zone.
