摘　　要：文章以芷锚湾秋季近岸海水为研究对象,运用《海水水质标准》的评价方法,分析海水重金属含量分布和特征。结果表明:海水中的As和Cu元素含量呈北低南高之势,Zn、Cd和Pb元素含量大体为离岸浓度变低;通过对评价区各项环境因子含量和各类水体标准值进行比较,As、Zn和Cd元素含量均达到一类水质要求,Cu元素含量属于轻度污染,Pb元素含量属于较清洁,表明评价区总体属于轻度污染海域。The study focused on the distribution and characteristics of heavy metal content in nearshore seawater in Zhimao Bay during autumn.The evaluation method of“Water Quality Standards for Seawater”was used to analyze the heavy metal content.The results showed that the content of As and Cu elements in seawater exhibited a trend of decreasing from north to south,while the content of Zn,Cd,and Pb elements generally decreased with increasing offshore distance.By comparing the content of various environmental factors and the standards for different types of water bodies in the evaluation area,it was found that the content of As,Zn,and Cd elements met the requirements for ClassⅠwater quality,the content of Cu element indicated mild pollution,and the content of Pb element indicated relatively clean conditions.Overall,the evaluation area can be classified as a mildly polluted marine area.
