| 摘 要： | 根据2010年3月(冬季)、5月(春季)、8月(夏季)、11月(秋季)对江苏省如东县贝类养殖区4次现场监测资料,着重对养殖区海水和表层沉积物中重金属的分布特征进行了分析,并对养殖区进行了生态环境质量评价及潜在生态风险评价。结果表明:海水中重金属污染程度顺序为Pb>Zn>Hg>Cu>As>Cd;表层沉积物中重金属的污染程度顺序依次为Zn>Pb>As>Cu>Hg>Cd;表层沉积物中重金属的潜在生态危害程度顺序依次为Hg>Cd>As>Pb>Cu>Zn。4次调查结果的多种重金属的潜在生态风险指数(RI)均低于140,表明这些重金属对海洋生态系统的潜在生态风险属于低潜在生态风险水平,养殖环境良好。

| Abstract: | Based on the data of shellfish culture area of Rudong,Jiangsu province in March,May,August and November, 2010,the content and distribution of heavy metals in the sea water and surface sediments were analyzed. Eco-environmental quality and potential ecological risk in the shellfish culture area were also assessed. The results showed that:in seawater, the order of pollution extents of heavy metals was Pb>Zn>Hg>Cu>As>Cd. At the same time,in the surface sediments,the order of pollution extents of heavy metals was Zn>Pb>As>Cu>Hg>Cd. The sequence of potential ecological risk of different heavy metals in surface sediments was Hg>Cd>As>Pb>Cu>Zn. The potential ecological risk index (RI) was less than 140, this revealed that the potential ecological risk of these heavy metals to the ocean ecology system is very light, the environmental quality of the culture areas was good. |
