| 摘 要： | 根据2009年10月的调查数据对辽宁绥中海域海水和表层沉积物中的重金属(砷、汞、铜、铅、锌和镉)进行了研究。用单因子指数评价法对海水中的重金属进行了评价,结果表明,海水中的Zn、Hg含量均超过《海水水质标准》(GB3097-1997)中Ⅰ类海水水质标准。采用《海洋沉积物质量》(GB 18668-2002)Ⅰ类海洋沉积物质量标准评价,表层沉积物中的As超标一倍以上。采用瑞典科学家Hkanson的潜在生态危害指数法进行评价,生态危害程度As>Hg>Cd>Cu>Zn>Pb。

| Abstract: | According to the survey data in Oct.2009,heavy metals(arsenic,mercury,copper,lead,zinc and cadmium) in seawater and surface sediments were studied in Suizhong Harbor,Liaoning.The single factor index method was applied to analyze heavy metals’ pollution in sea water.Results showed that concentrations of Zn and Hg both exceeded the standard of first grade seawater quality of China(GB 3097-1997).The content of As exceeded the standard of first grade marine sediments(GB 18668-2002) more than 1 time.Potential Ecological Risk Index proposed by Swedish scientist Hkanson was applied to evaluate the harm of the heavy metals.The results indicated that monitored heavy metals’ risks were slight,and order of the potential ecological risk was As>Hg>Cd>Cu>Zn>Pb. |
