摘要: 摘要:本文采集了湄洲湾20个点位4批次水样,1次沉积物样,用原子荧光、原子吸收和多功能极谱仪测定海水和沉积物中As的含量。采用单因子污染指数法和内梅罗综合污染指数法对湄洲湾水域海水和沉积物中的砷及重金属进行综合评价。结果表明,湄洲湾水域海水中的砷及重金属单因子污染指数Pi<1,均符合第二类海水水质标准,内梅罗指数I<1,总体处于清洁水平,质量状况良好;沉积物中的砷及重金属单因子污染指数Pi<1,均符合第一类海洋沉积物质量标准,内梅罗指数I<1,总体处于清洁水平,质量状况良好。便简要分析了湄洲湾水域海水、沉积物中砷及重金属分布特征、季节变化情况。

Abstract: Abstract:To investigate into the water pollution caused by arsenic and heavy metal in meizhou Bay,4 batches of water samples and 1 batches of sediment from 20 sites are collected and the contents of As,Hg,Cu,Pb,Zn,Cd are measured with the application of atomic fluorescence spectrophotometer and atomic absorption spectrometry and Multi-functional Polarograph method. The results show that, Meizhou Bay waters and sediments of Arsenic and Heavy Metals in good condition. Analysis of arsenic and heavy metals in water and sediment distribution,seasonal variation and pollution in the meizhou bay.
