2017—2019年河南省包装饮用水抽检结果分析

Monitoring Results Analysis of Bottled Drinking Water Samples in Henan Province,China,2017—2019

目的分析研究2017—2019年河南省包装饮用水的质量情况及存在的问题。方法根据国家食品安全监督抽检实施细则,在河南省不同区域采集具有代表性的包装饮用水共1339份。饮用天然矿泉水选择界限指标、镍、锑、溴酸盐、硝酸盐、亚硝酸盐、大肠菌群、粪链球菌、产气荚膜梭菌、铜绿假单胞菌10个检验指标进行监测分析,饮用纯净水和其他饮用水选择耗氧量、浑浊度、亚硝酸盐、余氯、三氯甲烷、溴酸盐、挥发性酚、大肠菌群、铜绿假单胞菌9个检验指标进行监测分析。结果经检测,2017—2019年抽检的1339份包装饮用水样本,总不合格率为4.1%,其中饮用天然矿泉水、饮用纯净水和其他饮用水的抽检不合格率分别为2.4%、4.1%和5.4%,不合格项目主要是铜绿假单胞菌、溴酸盐、亚硝酸盐、耗氧量、界限指标、余氯6个项目。其中铜绿假单胞菌不合格率为1.9%,高于其他指标。结论河南省包装饮用水总体质量尚可,但仍存在不合格样品,建议生产企业从水源、生产过程和封装,严格按照卫生规范操作,监管部门应重点关注监测分析中的不合格项目,采取靶向抽检。

Objective To investigate the quality and problems of bottled drinking water in Henan province,China,from 2017 to 2019.Methods According to the Implementation Rules for National Food Safety Sampling Inspection Program,1339 samples of bottled drinking water were collected in different regions of Henan province.Ten parameters were monitored for the natural mineral drinking water,including limit indicators,nickel,antimony,bromate,nitrate,nitrite,coliform,Streptococcus faecalis,Clostridium perfringens,and Pseudomonas aeruginosa.As for purified drinking water and other types of drinking water,nine parameters were monitored,including oxygen consumption,turbidity,nitrite,residual chlorine,chloroform,bromate,volatile phenol,coliform,and Pseudomonas aeruginosa.Results Among 1339 samples of bottled drinking water collected from 2017 to 2019,the overall percentage of samples that did not meet the national drinking water quality standards was 4.1%,with 2.4%for natural mineral drinking water,4.1%for purified drinking water,and 5.4%for other types of drinking water.The unqualified indices were Pseudomonas aeruginosa,bromate,nitrite,oxygen consumption,limit indicators,and residual chlorine,respectively.The unqualified rate for Pseudomonas aeruginosa was 1.9%,which was higher than those for other parameters.Conclusion The overall quality of bottled drinking water in Henan province is acceptable,but there are still samples below the quality standards.It is suggested that enterprises should operate in strict accordance with hygiene requirements during the process of source water management,manufacturing,and product packaging.The regulatory authorities should pay close attention to the main parameters for which bottled drinking water fail to meet the quality standards and adopt targeted sampling.
