چکیده انگلیسی


• Successfully deployed and retrieved innovative artificial mussels (AM) device in waterways of Bangladesh for the first time
• Detected eleven metals including Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, U, Zn
• Identified metal pollution “hot spots” in waterways of Bangladesh
• Categorised pollution monitoring sites into most, moderate and least hazardous sites;
• Metals pollution may impact on local water quality, seafood catch, aquaculture, livelihoods and public health

Using artificial mussels (AMs), this study reports and compares time-integrated level of eleven trace metals (Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, U, Zn) in Karnafuli River estuary and coastal area of the Bay of Bengal, Bangladesh.Through this study, “hot spots” of metal pollution were identified. The results may demonstrate that the Karnafuli Estuary, and adjacent coastal area of Chittagong, Bangladesh are highly polluted by high risk metals (cadmium, chromium, copper, mercury, nickel, lead, uranium). Agricultural, domestic and industrial wastes directly discharged into the waterways have been identified as the main causes of metal pollution in Chittagong, Bangladesh. The high level of metal pollution identified may impact on local water quality, and seafood catch, livelihoods of people and public health resulting from seafood consumption. There is a need for regular monitoring to ascertain that local water quality with respect to metal levels are within acceptable levels to safeguards both environmental health and public health.
