浅谈海南岛周边海域表层沉积物重金属污染现状与评价

Discussion on the Current Situation and Evaluation of Heavy Metal Pollution in Surface Sediments of the Surrounding Sea Area in Hainan Island

根据2020—2022年监测海南岛周边海域海洋生态环境获得的数据,文章对表层沉积物中Hg、Cu、Pb、Cd、Cr、Zn和As等7种重金属元素的含量进行了分析。文章还根据《海洋沉积物质量》(GB18668-2002)标准,通过单因子污染指数法对海南岛周边海域沉积物的重金属污染状况进行评价,为保护海南岛周边海域的海洋生态环境提供科学参考。

Based on data obtained from monitoring the marine ecological environment around Hainan Island from 2020 to 2022,the article analyzed the content of seven heavy metal elements,including Hg,Cu,Pb,Cd,Cr,Zn,and As in surface sediment.The paper also evaluates the heavy metal pollution status of sediment in the surrounding waters of Hainan Island according to the single factor pollution index method of Marine Sediment Quality(GB18668-2002),providing scientific reference for protecting the marine ecological environment of the surrounding waters of Hainan Island.
