| 摘 要： | 对厦门海域表层沉积物中有机氯农药和多氯联苯的含量与分布进行了调查研究.调查结果表明厦门海域HCHs和PCBs含量较低,远低于国家海洋沉积物质量标准第一类底质标准的阈值,说明其污染已受到有效控制;但厦门海域表层沉积物中DDTs含量较高,部分海区已经超出或者接近国家海洋沉积物质量标准第一类底质标准的阈值.DDTs和PCBs有极为相似的分布特征,而HCHs的分布特征则不尽相同.

| Abstract: | The concentrations and distributions of organic chlorine pesticides and polychlorinated biphenyls were investigated. The results indicated that the concentrations of HCHs and PCBs is much lower than the minimum value of Category Iof Quality Standards for Sediment. It showed that the pollution state of HCHs and PCBs had been controlled valuably, but the concentration of DDTs in surface sediments of Xiamen areas was relatively high, even higher than or close to themaximum value of Category I of Quality Standards for Sediment in some waters. The distributions of DDTs and PCBs is very similiar, but HCHs is different. |
