【摘要】 在1998~2004年对舟山海域4个县区40种海产品的石油烃含量,采用分子荧光光度法进行了检测,结果表明:(1)舟山群岛海洋动物体内石油烃含量的种间分布差异较大,以瓣鳃纲和腹足纲为主的软体动物的生物富集作用具有明显的区域和时段特征;(2)舟山群岛海洋动物体内石油烃含量在1998年和2001年的3 a有一个明显下降过程,而在2003和2004年又有了明显的上升趋势并在总体上已超过了1998年的水平;(3)以营埋栖的缢蛏和活动范围有限的龙头鱼,适于作为潮间带泥滩或河口区域等不同栖息生境有机污染的指示物种。更多还原

【Abstract】 The distributions of petroleum hydrocarbon in 40 species marine products from 4 counties of Zhoushan Islands of Zhejiang province,were investigated during 1998 to 2004.The results show that the sequence of the petroleum hydrocarbon content is that mollusk lamellibranchiata,mollusk gastropoda,crustacean caridoid,fish,and mollusk cephalopoda.The marine products from this area were polluted widely by the petroleum hydrocarbon,the concentration of petroleum hydrocarbon in Mollusk inhabiting in the tideland was higher generally than in fish and Crustacea.A significant difference in geographic and temporal distribution patterns for petroleum hydrocarbon levels in Mollusk was observed in this area.Levels of petroleum hydrocarbon were higher in Shengsi,located in the estuary of Changjiang river.And it’s potential for Sinonovacula constricta and Harpodon nehereus as the indicatory species which would indicate the contamination of organic compound in different habitat such as tideland and estuary areas.更多还原
