摘要
提出了研究水体沉积物中多环芳烃的意义;针对国内外河流、河口及海岸带水体沉积物中多环芳烃污染状况的环境调查进行了评议,并就国内典型区域进行了污染特征及来源的剖析;提出了水体沉积物中多环芳烃生态风险评价的方法及防治措施。
The significance in the study of PAHs in aquatic sediment was given and a survey on PAHs pollution in surface sediments from both domestic and oversea rivers,estuaries and coastal zones was made.The pollution characteristics and sources of PAHs in typical areas were analyzed and the method of ecological risk assessment and some prevention measures to PAHs pollution were given.
