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%)。
 
Species sensitivity distributions ( SSD ) method was used to assess the ecological risk of eight heavy metals ( As , Cd , Cr , Cu , Hg , Mn , Pb , Zn ) to marine organisms.According to the investigation data , the ecological risks of 7heavy metals ( As , Cd , Cr , Cu , Hg , Pb , Zn ) to marine organisms in Chi-nese offshore were assessed , and the ecological risks of 6heavy metals ( As , Cd , Cu , Hg , Pb , Zn ) to marine organisms in Fujian's main bays were also studied.The results showed that the ecological risks of 7 heavy metals in the Chinese offshore were in the order that Bohai Sea ( 20.67% ) >Yellow Sea ( 18.39% ) > East China Sea ( 15.94% ) >South China Sea ( 11.26% ), and the ecological risk of 6heavy metals in 13es- tuaries and bays in Fujian Province were in the order that Quanzhou Bay ( 47.44% ) >Xiamen Bay ( 47.16% ) > Luoyuan Bay ( 43.03% ) >Shacheng Port ( 34.65% ) >Shenhu Bay ( 30.34% ) >Sansha Bay ( 28.64% ) > Minjiang Es- tuary ( 20.55% ) >Zhaoan Bay ( 20.42% ) >Xinghua Bay ( 18.37% ) > Meizhou Bay ( 17.24% ) .
