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，收集并研究了来自韩国，俄罗斯，中国，香港，香港，菲律宾，越南，越南，柬埔寨，柬埔寨，泰国，印度尼西亚和印度的贻贝，并进行了研究，以监测持久有机氯的海洋污染，例如PCBS，DDTS，DDTS，DDT及其基质及其化合物（Chlordane）（chllordane）（chllordane nocy）（六边形环己烷）和HCB（六邻苯甲苯）和有机蛋白化合物，例如Tributyltin（tbt），二丁基丁素（DBT）和单丁丁蛋白（MBT）。从其中一些国家采样了沉积物，鱼类，鸟类，小鲸类等，并对海洋污染进行了调查。尽管尚未完成化学分析，但在贻贝，沉积物和生物样品中获得了以下暂定结果；丁基蛋白（BTS）和有机型化合物（OC）揭示了亚洲发展中国家沿海水域的广泛污染。在具有强化划船活动和沿海水产养殖设施的地点发现了相对较高的BT，这意味着将TBT用作杀菌剂在船体船体和海洋水产养殖中使用的防污涂料中的使用。 BT衍生物在贻贝中的组成是根据TBT> DBT> MBT的顺序，暗示了亚洲海岸最近存在的来源。尽管贻贝中的OC浓度小于BTS，但CC残基显然在较高营养动物（例如鸟类和小鲸类动物）中占主导地位。在贻贝中发现的P，P-DDT的大量残留物表明目前用于亚洲公共卫生目的的DDT使用。印度的HCHS和DDTS污染显然高于其他亚洲发展中国家。这些结果清楚地表明，亚太地区的水生环境仍然经历了OCS的输入。我们认为，这是有关亚洲发展中国家有毒有机氯和有机素对海洋污染监测的首次综合报告，使用贻贝作为生物招标者。
