Abstract

Shipbreaking has obtained great importance in the micro and macro economy of poverty-stricken Bangladesh for being a profitable industry in spite of having a number of environmental and human health hazards. This study focuses on the Ship Breaking and Recycling Industry of Bangladesh to evaluate the pollution in water and measure the adverse effect on biodiversity. Here the water quality parameters like pH, Salinity, Alkalinity, Hardness, Electrical Conductivity (EC), Turbidity, Biological Oxygen Demand (BOD), Dissolved Oxygen (DO), Pb, Cr, Cd, Fe concentrations of the sea water of shipbreaking yards of Bhatiary, pond water and tube well water has analyzed. Turbidity during tide-1 was observed 2624 NTU where the standard value is 5 NTU. Similarly, BOD was measured about 11.30 mg/l which was above the permissible limit in the seawater during tide-2. Value of Pb was about 0.07018 mg/l in seawater during tide-1 which is above the permitted limit. The elevated level of different physicochemical parameters and heavy metal is a serious threat for pollution not only for the biodiversity but also for the environment. Evaluation of water pollution in water bodies by the establishment of ship breaking industry was assessed by comparing these data with WHO and BSTI standard and evaluation of the adverse effect on biodiversity was established by observing the range of the parameters measured from the water bodies.
