湛江赤坎水库水体重金属污染特征研究

Analysis of Characteristics of Heavy Metal Pollution in the Water Source of Chikan Reservoir

2018年1-12月,对湛江市赤坎水库水体中的Fe、Al、Mn、Cu、Zn、Cd、Cr、As等8种重金属离子的含量进行检测分析。实验结果表明:水体中Zn、Mn、Cr、Cu和As含量低于地表水环境质量Ⅱ标准,而Fe、Al和Cd含量高于地表水环境质量Ⅱ标准,表明水体存在Fe、Al和Cd污染隐患。通过对湛江市赤坎水库水体的检测和分析,旨在为赤坎水库水质监测、评价和控制提供基础的科学依据。

From January to December 2018,the contents of Fe,Al,Mn,Cu,Zn,Cd,Cr,As and other 8 heavy metal ions in the water of Chikan reservoir in Zhanjiang city were detected and analyzed. The experimental results showed that the content of Zn,Mn,Cr,Cu and As in water was lower than the surface water environmental quality standard Ⅱ,but the content of Fe,Al and Cd was higher than the surface water environmental quality standard Ⅱ,which showed that Fe,Al and Cd pollution hazard existed in water. Through the detection and analysis of Chikan reservoir water in Zhanjiang city,it was aimed to provide basic scientific basis for the monitoring,evaluation and control of Chikan reservoir water quality.
