项目摘要

In this project, mussels from South Korea, Russia, China, Hong Kong, Philippines, Vietnam, Malaysia, Cambodia, Thailand, Indonesia and India were collected and studied for monitoring marine pollution by persistent organochlorines such as PCBs, DDTs (DDT and its metabolites), CHLs (chlordane compounds), HCHs (hexachiorocyclohexanes) and HCB (hexachiorobenzene), and organotin compounds such as tributyltin (TBT), dibutyltin (DBT) and monobutyltin (MBT). Sediments, fishes, birds, small cetaceans etc. were also sampled from some of these countries and investigated on the marine pollution. Although chemical analyses am not yet completed, the following tentative results were obtained ;Butyltins (BTs) and organochiorine compounds (Ocs) in mussels, sediments and biological samples revealed widespread contamination along the coastal waters of Asian developing countries. Relatively high concentrations of BTs were found at locations with intensive boating activities and coastal aquaculture facilities, implying the usage of TBT as a biocide in antifouling paints used on boat hulls and in marine aquaculture. The composition of BT derivatives in mussels were in the order of TBT> DBT > MBT, suggestive of the presence of recent sources in Asian coast. While concentrations of Ocs in mussels were less than BTs, CC residues were apparently dominant in higher trophic animals such as birds and small cetaceans. Considerable residues of p,p-DDT found in mussels indicated current usage of DDT for public health purposes in Asia. HCHs and DDTs contamination in India was apparently higher than in other Asian developing countries. These results clearly indicated that the aquatic environment in the Asia-Pacific region still experience Ocs input.We believe that this is a first comprehensive report on the monitoring of marine pollution by toxic organochlorines and organotins in Asian developing countries, using mussels as bioindicators.

在这个项目中，采集了来自韩国、俄罗斯、中国、香港、菲律宾、越南、马来西亚、柬埔寨、泰国、印度尼西亚和印度的贻贝，以监测持久性有机氯对海洋的污染，这些有机氯包括多氯联苯、滴滴涕(DDT及其代谢物)、氯丹化合物(CHLS)、六六六(六六六)和六六六(六苯)，以及有机锡化合物如三丁基锡、二丁基锡和单丁基锡。还从其中一些国家采集了沉积物、鱼类、鸟类、小型鲸目动物等，并对海洋污染进行了调查。虽然化学分析尚未完成，但已获得以下初步结果：贻贝、沉积物和生物样品中的丁基锡(BTS)和有机氯化合物(OCS)显示，亚洲发展中国家沿海水域普遍存在污染。在划船活动密集的地点和沿海水产养殖设施中发现了相对较高浓度的BTS，这意味着在船体和海洋水产养殖中使用TBT作为生物杀菌剂。贻贝中Bt衍生物的组成顺序为TBT&GT；DBT&GT；MBT，提示亚洲沿海存在新近来源。虽然贻贝中OCS的浓度低于BTS，但在鸟类和小型鲸目动物等营养价值较高的动物中，CC残留量明显占优势。在贻贝中发现的相当大的p，p-DDT残留量表明，亚洲目前出于公共卫生目的使用了DDT。印度的六六六和滴滴涕污染明显高于其他亚洲发展中国家。这些结果清楚地表明，亚太地区的水环境仍经历着OCS输入。我们认为，这是亚洲发展中国家首次以贻贝为生物指示物监测有毒有机氯和有机锡对海洋污染的综合报告。
