摘要

摘要: 采用单因子评价法和内梅罗指数法对湖南郴州柿竹园矿区乡镇地下饮用水源丰、枯水期重金属进行水质评价。结果表明，Fe、Mn、Ba、Zn、Cu、As、Pb、Ni、Cr、Cd和Hg等重金属在矿区乡镇地下水中普遍存在，其中Mn、Fe和As为该地区乡镇地下水中的主要重金属污染物，其检出浓度分别超过GB 5749—2006《生活饮用水卫生标准》限值的14.72、1.73和1.61倍。枯水期柿竹园矿区乡镇地下水水质相对丰水期差，该地区乡镇地下饮用水源水质评价结果为较差、良好和优良的在枯水期分别占饮用水源取样点总数的5%、10%和85%；在丰水期分别占饮用水源取样点总数的5%、5%和90%。

Abstract: Water quality assessment for heavy metals in rural groundwater sources around Shizhuyuan Polymetallic Mine in Chenzhou, Hunan province in wet and dry seasons was carried out by using Single-factor Assessment Method and Nemerow Index Methods. The results showed that Fe, Mn, Ba , Zn , Cu , As, Pb , Ni, Cr , Cd and Hg were ubiquitous in rural groundwater sources. Mn, Fe and As were the main heavy metal pollutants in rural groundwater sources around Shizhuyuan mine area, with the detection concentrations exceeding Sanitary Standard for Drinking Water (GB 5749-2006) by 14.72, 1.73 and 1.61 times, respectively. The rural groundwater quality was poorer in dry season than that in wet season. The water quality in poor, good and excellent status in dry season accounted for 5%, 10% and 85% of the total rural groundwater sources, respectively, while in wet season it accounted for 5%, 5% and 90%, respectively.
