| 摘 要： | 根据2006年10月对长兴岛潮间带表层沉积物的监测数据,采用单因子污染指数法和Hakanson潜在生态风险指数法分别对重金属(Cu、Pb、Zn、Cd、Cr、Hg)和多氯联苯7种化学要素的污染状况及其生态风险程度进行了分析和评价。结果显示:长兴岛沉积物总体处于低污染水平和低潜在生态风险水平,但重金属Cd处于中等污染水平和中等潜在生态风险水平,为主要的污染要素和潜在生态风险因子。处在青草沙水库区域的B1样点的局部Hg污染和潜在生态风险应当引起注意

| Abstract: | According to the monitoring data of the surface sediments in the intertidal zone of Changxing Island in October 2006, the pollution status and the potential ecological risk of 7 typical pollutants including Cu, Pb, Zn, Cd, Cr, Hg and polychlorinated biphenyls were analyzed and assessed using methods of the single factor pollution index and the Hakanson potential ecological risk index, respectively. Results showed that, the comprehensive situation of the sediment quality was at a low level of pollution and potential ecological risk, while the heavy metal Cd was at a medium level of pollution and potential ecological risk, and it was the main pollutant and the key factor causing potential ecological risk. Meanwhile the pollution and the potential ecological risk of the heavy metal Hg needed attention in the sampling site of B1 which was located in the region of Qingcaosha Reservoir. |
