【摘要】 目的研究GB 5749—2006《生活饮用水卫生标准》中常规监测指示菌与介水传染病之间的相关性。方法从公共卫生科学数据中心获取2014年全国介水传染病发病数据和饮用水常规指示菌监测数据;采用主成分分析对全国22个省市常规指示菌合格率作排名和分级;对常规指示菌与介水传染病及常规指示菌间的相关性采用Spearman偏相关分析。结果在22个省市饮用水常规指示菌合格率分级中,黑龙江省、江苏省、北京市和河北省等级较高。枯水期间除总大肠菌群水平与副伤寒发病率呈正相关(P<0.05)外,其他指示菌与疾病之间均无显著相关性;4种常规指示菌间均两两呈正相关(P<0.05)。丰水期间除总大肠菌群水平与伤寒、副伤寒发病率呈正相关(P<0.05)外,其他指示菌与疾病之间无显著相关性;除大肠埃希菌与菌落总数无显著相关性外,其他常规指示菌间两两呈正相关。结论 GB 5749—2006中的常规指示菌与介水传染病相关性并不显著,建议进一步进行常规指示菌与介水传染病相关性的定量研究及探寻新型指示菌。更多还原

【Abstract】 Objective To know the microbiological monitoring situation in drinking water and to analyze the correlation between indicator bacteria regulated by Standards for Drinking Water Quality GB 5749-2006 and waterborne infectious diseases.Methods Data for 2014 national incidence of waterborne infectious disease and monitoring results of conventional indicator bacteria in drinking water from Public Health Science Data Center.They were analyzed using principal component analysis and Spearman correlations. Results Higher grade of qualified rate of indicator bacteria was found in Heilongjiang, Jiangsu, Beijing and Hebei among 22 provinces and cities. There was no correlation between mean of conventional indicator bacteria and morbidity of common waterborne infectious diseases except the total coliform bacteria and paratyphoid fever,four conventional indicator bacteria showed positive correlation two by two during dry season;There was no correlation between mean of conventional indicator bacteria and morbidity of common waterborne infectious diseases except the total coliform bacteria and typhoid,paratyphoid fever,four conventional indicator bacteria showed positive correlation two by two except E.coli and total bacterial count during wet season. Conclusion In general,there is no significant correlation between incidence of common waterborne infectious diseases and indicator bacteria regulated by GB 5749-2006. Further research should be conducted on quantitative relationship between waterborne infectious diseases and indicator bacteria,and new indicator bacteria should be explored as well.更多还原
