对三亚湾10个表层沉积物中的6种重金属元素进行分析,并运用潜在生态危害指数法对重金属的污染程度和潜在生态风险程度进行了评价。研究结果表明:表层沉积物中6种重金属平均含量高低依次为Zn〉Pb〉Cu〉As〉Cd〉Hg。10个站位单个重金属都处于低污染水平,重金属平均污染程度由大到小依次为Pb〉Zn〉Cu〉As〉Hg〉Cd;研究区域多种重金属综合污染程度均属于低污染。6种重金属生态危害程度大小是Hg〉Pb〉Cd〉Cu=As〉Zn;监测海域的总体潜在生态风险程度低。
對三亞灣10箇錶層沉積物中的6種重金屬元素進行分析,併運用潛在生態危害指數法對重金屬的汙染程度和潛在生態風險程度進行瞭評價。研究結果錶明:錶層沉積物中6種重金屬平均含量高低依次為Zn〉Pb〉Cu〉As〉Cd〉Hg。10箇站位單箇重金屬都處于低汙染水平,重金屬平均汙染程度由大到小依次為Pb〉Zn〉Cu〉As〉Hg〉Cd;研究區域多種重金屬綜閤汙染程度均屬于低汙染。6種重金屬生態危害程度大小是Hg〉Pb〉Cd〉Cu=As〉Zn;鑑測海域的總體潛在生態風險程度低。

Six heavy metals in ten surface sediment samples from Sanya Bay were analyzed and the degree of contamination and potential ecological risks were assessed by using potential ecological index methods.The results showed that the order of average heavy metal concentration of was Zn〉Pb〉Cu〉As〉Cd〉Hg.Every heavy metal in ten samples reached the pollution standard.The average degree of contamination was Pb〉Zn〉Cu〉As〉Hg〉Cd.The degree of integrated contamination index of six heavy metals was slightly polluted.The order of potential ecological risk level was Hg〉Pb〉Cd〉Cu=As〉Zn.The potential ecological risk level of the monitored area is slightly risky.
