对有色矿业周边环境重金属污染的监测

Heavy Metal Pollution Monitoring of Nonferrous Metal Pollution in Surrounding Environment

根据《重金属防治＂十二五＂规划》的要求,本实验对广西某有色矿业周边环境重金属污染进行了监测,对有色金属矿业区周围农田土壤、稻谷和井水进行采样,用火焰原子吸收法和石墨炉原子吸收法测定了采集样品中Cu、Zn、Pb、Cd、Cr含量,对结果进行了初步分析：按照国家标准指标判定,土壤受到了Cu、Zn、Pb、Cd污染;稻谷受到了Pb、Cd污染;矿区生活区水井水受到了Cd的污染。

According to the demand of the Twelfth Five-Year Plan controlling Heavy metal,heavy metal pollution monitoring of the nonferrous metal m ining surrounding environment in Guangxi was studied.The soil,rice and water around in the nonferrous metal mining area were sampled,then the contents of copper,zinc,lead,cadmium and chromium for samples were determined by Flame Atomic Absorption Spectrometry and Graphite Furnace Aatomic Absorption Spectrometry.The target was judged according to national standard.Results showed that soil was polluted by copper,zinc,lead and cadmium,rice was polluted by lead and cadmium,and water was polluted by cadmium.
