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.
本研究利用人工贻贝（AMs）报告并比较了孟加拉国卡纳富利河河口和孟加拉湾沿海地区11种痕量金属（镉、钴、铬、铜、铁、汞、锰、镍、铅、铀、锌）的时间积分水平。通过这项研究，确定了金属污染的“热点”。结果可能表明，孟加拉国吉大港的卡纳富利河口及其邻近沿海地区受到高风险金属（镉、铬、铜、汞、镍、铅、铀）的高度污染。直接排入水道的农业、生活和工业废物被确定为孟加拉国吉大港金属污染的主要原因。所确定 的高金属污染水平可能会影响当地水质、海产品捕捞、人们的生计以及因食用海产品而产生的公众健康。需要进行定期监测，以确保当地金属水平方面的水质处于可接受水平，以保障环境健康和公众健康。
