摘要: 测量茅尾海悬浮颗粒物中的 As、Cd、Cr、Cu、Ni、Pb、Zn 含量,研究其分布特征,并运用潜 在生态风险指数法和地积累指数法相结合对茅尾海中的悬浮颗粒物重金属含量进行风险评价。 结果表明:重金属含量均呈现出自西北向东南方向递减的趋势;重金属潜在生态风险等级为强生 态风险,其中 Cd 为严重的生态风险;地积累指数中 Cd 和 Cu 达到偏重度污染,As 主要为偏中度污 染,Zn、Ni 主要为轻度污染。重金属污染受人为影响较大,在悬浮颗粒物中 Cd 污染严重,其他重 金属均有不同程度污染。

Abstract: The contents of As,Cd,Cr,Cu,Ni,Pb,and Zn in the suspended particulate matter in the Maowei Sea were measured,their distribution characteristics were studied, and the risk of the suspended particulate matter in the Maowei Sea was evaluated by the combination of potential ecological risk index method and ground accumulation index method. The results showed that the content of heavy metals decreased from northwest to southeast;the potential ecological risk level of heavy metals was a strong ecological risk, and Cd was a serious ecological risk;in the land accumulation index,Cd and Cu were heavy polluted,As were mainly moderately polluted,and Zn and Ni were mainly slightly polluted. Heavy metal pollution is greatly affected by human beings. Cd pollution in suspended particulate matter is serious,and other heavy metals are polluted to varying degrees.

Key words: Maowei Sea, suspended particulate matter, heavy metals, ecological risk assessment
