摘　　要：在河北省扇贝养殖区7条主要入海河流河口区域设立监测站位,于2007年5月枯水期和8月丰水期对水样和沉积物样品中石油类含量进行监测。河口水样平均石油类含量丰水期为0.94mg/L,超标18.8倍;枯水期为0.51mg/L,超标10.2倍;丰水期明显高于枯水期。河口沉积物中石油类含量丰水期为473μg/g,为标准值的0.95倍;枯水期为777μg/g,为标准值的1.55倍;部分河口沉积物中石油类含量超标严重。河口区域水体石油类污染的主要原因是大陆径流。In this paper, water and sediment from the estuaries of the major rivers in the scallop culture zone of Hebei province was sampled during both dry season and wet season, and the oil content was monitored, assessed and studied. The research showed that the average oil content of the body of water from the estuaries during dry season was 0.51 mg/L and rose to 0.94 mg/L during wet season, which was significantly higher than oil content during dry season; The average oil content of sediment from the estuaries during dry season was 777 μg/g and dropped to 473 μg/g during wet season. However, the oil content of sediment in some sections of rivers was higher than the national standard, indicating that these sections of rivers were severly contaminated by oil pollution. The oil pollution in these estuary water bodies was chiefly caused by continental runoff, whereas the release of oil pollutant from the sediment functioned as a secondary cause.
