本研究使用贻贝样本测量柬埔寨、中国、香港、印度、印度尼西亚、日本、韩国、马来西亚、菲律宾和越南等亚洲国家沿海沃茨中的多溴联苯醚（PBDEs）和有机氯（OCs）水平。在所有分析样本中均检测到多溴二苯醚，浓度范围为0.66至440纳克/克脂重。在韩国、中国香港和菲律宾沿海沃茨的贻贝中发现的多溴二苯醚浓度显然较高，这表明该区域及其周围存在这些化学品的重要来源。关于多溴二苯醚同系物的组成，BDE-47、BDE-99和BDE-100是大多数样本中的主要同系物。在所分析的有机氯化合物中，DDTs的浓度最高，其次是PCBs> CHIL> HCHs> HCB。贻贝样本中滴滴涕、多氯联苯、氯化锂和六氯环己烷的总浓度分别为21至58 000、3.8至2000、0.93至900和0.90至230纳克/克脂重，分别在香港、越南和中国的贻贝中发现了高浓度的滴滴涕;在日本、香港以及韩国、印度尼西亚、菲律宾和印度的工业化/城市化地区发现了多氯联苯;在日本和香港发现了氯化锂;在印度和中国发现了六氯环己烷。这些国家似乎是亚洲相应污染物的可能排放源，反过来可能影响其全球分布。
Mussel samples were used in this study to measure the levels of polybrominated diphenyl ethers (PBDEs) and organochlorines (OCs) in the coastal waters of Asian countries like Cambodia, China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, the Philippines, and Vietnam. PBDEs were detected in all the samples analyzed, and the concentrations ranged from 0.66 to 440 ng/g lipid wt. Apparently higher concentrations of PBDEs were found in mussels from the coastal waters of Korea, Hong Kong, China, and the Philippines, which suggests that significant sources of these chemicals exist in and around this region. With regard to the composition of PBDE congeners, BDE-47, BDE-99, and BDE-100 were the dominant congeners in most of the samples. Among the OCs analyzed, concentrations of DDTs were the highest followed by PCBs > CHILs > HCHs > HCB. Total concentrations of DDTs, PCBs, CHLs, and HCHs in mussel samples ranged from 21 to 58 000, 3.8 to 2000, 0.93 to 900, and 0.90 to 230 ng/g lipid wt., respectively. High levels of DDTs were in mussels from Hong Kong, Vietnam, and China; PCBs were found in Japan, Hong Kong, and industrialized/urbanized locations in Korea, Indonesia, the Philippines, and India; CHLs were found in Japan and Hong Kong; HCHs were found in India and China. These countries seem to play a role as probable emission sources of corresponding contaminants in Asia and, in turn, may influence their global distribution.
