摘　　要：根据2006年5月对东海沿岸9个区域贝类的监测结果,探讨分析了调查海域的6种贝类体内石油烃含量的分布特征,采用单因子污染指数法按照海洋生物质量(GB18421-2001)评价标准评价了监测海域贝类的石油烃污染状况。结果表明,东海沿岸的9个海域的6种受测贝类体内石油烃含量分布范围1.28～37.6mg/kg(湿重),平均含量10.78mg/kg,总体上符合《海洋生物质量》一类标准(15.0mg/kg);6种贝类体内种间石油烃平均含量分布从大到小依次是:牡蛎>毛蚶>四角蛤蜊>文蛤>贻贝>泥蚶,其中牡蛎平均含量达到15.62mg/kg,超出海洋生物质量一类标准。从区域分布看,长江口和江苏如东沿岸海域的牡蛎石油烃的平均污染指数较高,分别为1.91和1.19,受到重度污染。On the basis of monitoring data of shellfish in 9 regions along the East China Sea coast in May of 2006, the distributional feature of petroleum hydrocarbon （ TPH ） concentration in six species was analyzed, and the pollution situation was assessed with single index method and National Marine Biological Quality （ GB 18421 - 2001 ）. Results indicated that the TPH concentration of six shellfishes varied from 1.28 mg / kg.wet to 37.6 mg / kg.wet with a mean value 10.78 mg / kg.wet, conforming to the first level of criterion （ 15.0 mg / kg ）. The TPH in six shellfishes ranked as： Crassostrea plicatula 〉Arca subcrenata〉 Mactra veneriformis〉 Meretrix meretrix 〉 Mytilus edulis 〉 Arca ganosa and the highest value 15.62 mg /kg.wet laid in Crassostrea plicatula which went beyond the first level. Among all the monitoring areas, the Changjiang estuary and Rudong region in Jiangsu province were seriously polluted by TPH with the higher pollution index 1.91 and 1.19, respectively.
