摘　　要： 以广东省清远市某村庄遭受酸性矿山废水污染的村边水沟及3个与水沟距离不同的居民水井水样为研究对象,探讨了酸性矿山废水对农村居民饮用水和灌溉水水质的影响。结果表明,酸性矿山废水严重影响村边水沟的水质,其Cd、Pb、Zn含量和pH超过了田间灌溉水质量标准,不宜用于农田灌溉;而居民井水的水质受到水沟污水的影响,影响程度与它们之间的距离呈负相关;3个居民井水的Cd、Pb、Zn含量和pH均超过生活饮用水卫生标准,不适宜作为生活饮用水。 Water samples within 3 wells and a ditch round a village from Qingyuan City,Guangdong Province of China were analyzed in order to elucidate the influence of acid mine drainage on drinking water and irrigation water in rural area.The ditch was contaminated by acid mine drainage.Results showed that acid mine drainage impacted seriously water quality of the ditch near the village.Cd,Pb and Zn concentrations and pH of the ditch water exceeded Standards for Irrigation Water Quality.The ditch water can not be used to irrigat crops.Water quality of the wells was affected by the ditch water.The influence degree was negatively correlated with the distance between the well and the ditch.Cd,Pb and Zn concentrations and pH of the water samples in 3 wells exceeded Standards for Drinking Water Quality.And the well water can not be used for drinking.
