| 摘 要： | 2013年对长江口及浙江近岸海域62个站位表层沉积物中多环芳烃(PAHs)进行了测定.结果表明,16种美国EPA优先控制的PAHs均有检出,PAHs总量水平(干重)为31.8~384μg·kg-1,平均含量为131.1μg·kg-1.其分布受到陆源输入和点源污染的影响,高值区域出现在长江口2号站位和宁波21号站位附近.与国内外其它海区相比,调查海域PAHs总体处于较低污染水平.调查海域沉积物中PAHs以4环、3环为主,来源分析显示PAHs主要来源于木柴、煤炭燃烧.利用沉积物质量基准法(SQGs)评价结果显示,调查海域表层沉积物中PAHs处于较低的生态风险水平;按照沉积物质量标准法(SQSs)评价结果表明,调查海域表层沉积物的PAHs污染已经具有一定程度的"显见生态负效应",需要采取相应的措施进行污染控制和削减.
