淮南老鳖塘与刘岗塘水体的重金属污染研究

Pollution of heavy metals in water of Laobie pond and Liugang pond in Huainan,Anhui province

采用原子吸收分光光度法对淮南谢二矿塌陷区老鳖塘与刘岗塘水体中Fe、Pb和Zn等重金属的含量进行了检测。结果表明:老鳖塘与刘岗塘水体中的Fe含量分别超出了集中式生活饮用水地表水源地补充项目标准限值的3倍和5.9倍;两塘水体中的Pb含量分别属于地表水环境质量国家标准的Ⅳ类和Ⅴ类水质范畴;Zn的含量均属于地表水环境质量国家标准的Ⅴ类水质范畴。综上可见淮南煤矿塌陷区水体的重金属污染状况较严重。

The concentration of Fe, Pb and Zn in water of Laobie Pond and Liugang Pond of mining subsidence area in Huainan were researched using atomic absorption spectrometry. The results showed that the pollution in these areas was quite severe. The content of Fe was 3 and 5.9 times more than the quality standard for Centralized drinking surface water in Laobie Pond and Liugang Pond respectively. The concentration of Pb accorded with the fourth and fifth grade of the environmental quality standards for surface water in Laobie Pond and Liugang Pond. While Zn in both ponds was in accord with the fifth grade of the quality standard.
