以粤北某铀矿周边地表水为研究对象,用ICP-MS对21个样本进行放射性和重金属元素分析,采用内梅罗法对水质进行评价,为矿区地表水污染现状提供科学数据支持。结果表明: 1)矿区周边地表水超标元素为U、TI、Pb、As,其中U含量为4.194 ~ 114.7 μg /L,最高超标1倍多。2)铀矿开采的污染来源主要有矿井水、碎矿废水、废石堆放场产生的废水,此外农田、养殖场废水也不容忽视。3)该铀矿周边地表水污染状况整体良好,Ⅱ号水体较Ⅰ号水体污染状况严重,其中20号采样点评价等级较低。

Twenty-one surface water samples were collected around a uranium-mine in northern Guangdong. The samples were measured by inductively coupled plasma mass spectrometry for the concentrations of radioactive and heavy metal elements, Nemerow index was used to evaluate water quality. The results showed that ： 1 ） The excessive elements of surface water surrounding the mining area were U, Ti, Pb, As. Concentration of U was from 4. 194 to 114. 7 μg/L, exceeding the ＂Regulations for Radiation and Environment Protection in Uranium Mining and Millin...
