摘要(Abstract):
利用物种敏感性分布(species sensitivity distribution,SSD)方法构建常见重金属元素对海洋生物的SSD曲线,在此基础上,结合实际调查数据,计算了中国近海7种重金属(As、Cd、Cr、Cu、Hg、Pb、Zn)和福建主要海湾6种重金属(As、Cd、Cu、Hg、Pb、Zn)对海洋生物的潜在影响比例(PAF),并分析了各种重金属在相应海区的联合生态风险(msPAF)。结果表明,中国近海水体重金属对海洋生物的生态风险大小顺序为:渤海(20.67%)>黄海(18.39%)>东海(15.94%)>南海(11.26%)。福建主要海湾水体重金属对海洋生物的生态风险大小顺序为:泉州湾(47.44%)>厦门湾(47.16%)>罗源湾(43.03%)>沙埕港(34.65%)>深沪湾(30.34%)>三沙湾(28.64%)>闽江口(20.55%)>诏安湾(20.42%)>兴化湾(18.37%)>湄洲湾(17.24%)。
