摘　　要：目的了解本地区集中式供水铝、铁、锰、铜、锌五种金属指标在本地饮用水水质中的风险程度,评估其对本地水质的影响。方法 2013—2015年在本市22个监测点随机抽取生活饮用水样本,采用国标方法对铝、铁、锰、铜、锌五个金属指标进行检测,使用多维灰聚类分析方法对水质进行风险评估。结果高风险样本占4.01%(46/1 147)、中风险样本占83.26%(955/1 147)、低风险样本占12.73%(146/1 147)。结论本地集中式供水水质铝、铁、锰、铜、锌五种金属指标处于中等风险水平。Objective To analyze and assess the risk of aluminum,iron, manganese,copper and zinc in Jiangmen, and we evaluate its impact on local water quality. Methods A total of 22 local monitoring stations were selected in 2013-2015.The indexes of aluminum,iron,manganese,copper and zinc were determined according to the national standards.Datas were analyzed by the multidimensional grey clustering assessment method. Results The high,medium and low level samples accounted for 4.01% （46/1 147）,83.26% （955/1 147） and 12.73% （146/1 147） separately. Conclusion The drinking water risk of aluminum,iron, manganese,copper and zinc belonged to the medium level.
