摘要: 以广东省某铀矿区为研究对象,利用电感耦合等离子体发射光谱仪(ICP-OES)测定了矿山、水冶厂及其周边地表水体共42个水样(包括工业废水、池塘水、溪流水、河水和矿区饮用水)中放射性元素(U和Th)和其它一些金属元素(Fe、Mn、Mg、Cu、Zn、Co、Ni、Li、Ca、Na、K、Al、Sr和Ba)的含量.由此确认铀矿区产生高污废水的重要环节和关键污染元素,并了解这些元素的迁移变化规律以及对周边地表水产生的影响.结果表明:(1)铀矿区产生高污外排废水的主要生产环节是采矿、铀矿堆浸和尾矿露天堆积,排放废水中U和Mn含量分别为0.238—8.700 mg·L-1和0.62—94.23 mg·L-1,均高于国家工业废水允许排放标准(GBJ8—74和GB8978—1996)的限定值;(2)铀矿周边用作当地农业灌溉和露天水源的溪流由于受纳了矿区外排废水,明显受到了U和Mn的污染:U含量在枯水期和丰水期分别为(0.415±0.619) mg·L-1和(0.233±0.308) mg·L-1,Mn含量在枯水期和丰水期分别为(8.72±12.8) mg·L-1和(8.56±12.61) mg·L-1;(3)受纳溪流中U、Fe的含量枯水期高于丰水期,而Mn和Cu的含量基本保持不变,且大多数元素的含量随着迁移距离的增加在枯水期和丰水期均呈下降趋势,指示污染源来自铀矿区;(4)铀矿区生产活动引起的地表水污染目前仅局限于铀矿区和周边较小的区域,但仍应引起重视.

Abstract: Forty-two water samples including industrial wastewater, pond water, river water and drinking water were collected in a uranium mining area in Guangdong Province for identifying the polluted waters and the key pollutants. The samples were measured by inductively coupled plasma Optical Emission Spectrometer for concentrations of U, Th, Fe, Mn, Mg, Cu, Zn, Co, Ni, Li, Ca, Na, K, Al, Sr and Ba. The results show that: (1) the uranium mining site is mainly subjected to the pollution of U and Mn, with concentrations ranging from 0.238 to 8.700 mg·L-1 and 0.62—94.23 mg·L-1, respectively, both exceeding the Chinese Integrated Wastewater Discharge Standard (GBJ8—74 and GB8978—1996); (2) the main pollutants of the recipient stream, which collects the discharge effluent, are U and Mn, with U concentrations of (0.415±0.619) mg·L-1 during dry seasons and (0.233±0.308) mg·L-1 during wet seasons, and with Mn concentrations of (8.72±12.8) mg·L-1 during dry seasons and (8.56±12.61) mg·L-1 during wet seasons; (3) the recipient stream has higher concentrations of U and Fe during dry seasons than wet seasons, while concentrations of Mn and Cu remain generally stable; and the studied elements show a general decreasing trend from the mining site; (4) the adverse environmental impact of the uranium industrial activities at the present is limited to a small area surrounding the industrial site.
