为摸清桂北某卡林型金矿区地下水环境重金属污染特征,分别在丰水期和枯水期对矿区的地下水进行取样监测,并采用标准指数法对监测结果进行评价.结果显示,研究区中的地下水受到重金属污染,主要的重金属污染因子为砷、铅、锑,污染程度从高到低依次为砷、铅、锑;地下水的pH值、铜、锌、镉、铬(六价)、汞的含量均满足《地下水质量标准》(GB/T 14848-2017)Ⅲ类标准的要求;污染范围主要在矿区内,没有对外环境地下水造成污染.
Study on the characteristics of heavy metal pollution in groundwater in a Carlin-type gold mining area in Northwest Guangxi
In order to find out the characteristics of heavy metal pollution in groundwater environment of a Carlin-type gold mining area in Northern Guangxi,the groundwater in the mining area was sampled and mo-nitored in the wet and dry seasons,and the monitoring results were evaluated by the standard index method.The results showed that the groundwater in the study area was polluted by heavy metals.The main heavy metal pollution factors were arsenic,lead and antimony,and the degree of pollution from high to low was ar-senic,lead and antimony.The pH value,copper,zinc,cadmium,chromium(hexavalent)and mercury of groundwater content meet the requirements of standard of'Groundwater Quality Standard'(GB/T 14848-2017)m.The pollution range is mainly in the mining area,and there is no pollution to the external envi-ronment groundwater.
