Detection and analysis of contaminant in bottled drinking water

目的对2017年云南省曲靖市(含2区1市6县)辖区内瓶、桶装饮用水进行污染物检测分析,了解辖区内瓶、桶装饮用水污染情况,为保证瓶、桶装饮用水的水质安全提供决策依据。方法根据饮用水类别分别按GB 19298—2014《食品安全国家标准包装饮用水》和GB 8537—2008《饮用天然矿泉水》标准中各污染物指定标准开展检测。结果 2017年采集辖区范围内102个品牌共计334批瓶、桶装饮用水,共有8个批次检出污染物,检出率为2.40%。其中有4批次产品检出铜绿假单胞菌,检出率为1.20%,2批次检出大肠菌群,检出率为0.60%,2批次亚硝酸盐超标,超标率为0.60%。结论大多数企业的产品安全,但仍存在铜绿假单胞菌等污染物的污染,应加强对瓶、桶装饮用水生产过程的监管,以保证饮用水质安全。
