参考美国EPA标准方法对厦门西港和闽江口的表层沉积物样品中持续性有机污染物PAHs、PCBs、和DDTs的含量及分布进行分析和考察，并对若干污染特征及成因进行探讨.结果表明，厦门西港沉积物样品中总PAHs含量(ng/g(干重))较闽江口海域为高，其中厦门样品测值范围是425.3-1522.4，大多高于1000，推断主要来源于石油类污染；闽江口为316.8-1260.7，大多低于1000，化石燃料燃烧可能是其主要来源.PCBs和DDT的分析结果表明，PCBs并非两海域的主要污染物，其含量(ng/g(干重))测值范围是厦门西港9.72—33.72，闽江口8.71—30.55；DDT类含量测值(ng/g(干重))厦门西港高于闽江口，范围分别为8.61—73.70和6.17—30.70(河口高值站位为63.88)，空间分布呈近岸高于远岸趋势.同时表明，在厦门海域表层沉积物中DDD是主要降解产物，而在闽江口DDE为主要降解产物.

The U. S. EPA analytical methods were employed to examine surface sediment concentrations of polycyclic aromatic hydrocarbons (PAHs) and organo-chlorides (PCBs and DDTs) in Xiamen Western Harbour (XM), in June, 1999, and Min River Estuary (MJ) in Oct., 1996.The spatial distribution and main possible sources of these pollutants were discussed. The ranges of PAHs concentration (ng/g(DW)) are 425 - 1520, with must values higher than 1000 in XM samples, and 315 - 1260, with most values lower than 1000 in MJ samples respectively. The main possible sources of sediment PAHs were identified as petroleum pollutants for Xiamen Western Harbour, and fossil fuel combustion products by river input for Minjiang Estuary, respectively. Sediment PCBs were found not the main pollutants in the study areas, with concentrations(ng/g(DW) ) ranging from 9.72 to 33.72, and from 8.71 to 30.55, in XM samples and MJ samples, respectively. Concentrations (ng/g(DW)) of sediment DDT and its degraded compounds show the trend of decreasing off the shore, while ranging from 20 to 70,and 6 to 30,in XM samples and MJ samples, respectively. Meaningful information also displays that the main degradation products are DDD in XM samples and DDE in MJ samples. As for the general results,the disadvantage of hydrodynamics,industrial and municipal wastewater discharge,and harbour activities are inferred as the main aspects of the factors affecting pollution in Xiamen Western Harbour,comparing with those in Minjiang Estuary,which is significantly affected by Minjiang River input. Measures for pollution prevention thus should be taken differently in the two areas.
