摘要
目的了解渭南市氟病区大荔县生活饮用水中氟化物含量状况,为地方性氟中毒病的防治和改水降氟提供客观、科学的依据。方法 2012~2018年对大荔县生活饮用水进行连续监测,监测分为丰水期和枯水期,不同水期均采集出厂水和末梢水样品。按照GB/T 5750-2006《生活饮用水标准检验方法》中离子选择电极法对样品进行检测和分析,依据GB/T 5749-2006《生活饮用水卫生标准》进行结果评价。结果 2012~2018年共检测生活饮用水样品568份,检出率为100%,不合格样品226份,合格率为60.21%。其中,2015年氟化物含量合格率最高为72.83%,2016年合格率最低为46.94%;丰水期合格率较枯水期稍高,大约为3.12%;末梢水合格率略高于出厂水,大约0.81%。结论大荔县生活饮用水中氟化物合格率相对较低,仍需进一步加大改水降氟工程力度,加强水质安全监测,为广大群众的饮水安全做好保障工作。
Objective To understand the fluoride content in drinking water in Dali County so as to provide objective and scientific basis for endemic fluorosis prevention and treatment as well as water improvement and fluoride reduction.Methods Drinking water samples of treated water and tap water were continuously monitored in Dali County from 2012 to 2018 in both flood and drought periods.All samples were tested and analyzed according to GB/T 5750-2006 Standard Examination Methods for Drinking Water.The test results were evaluated according to GB/T 5749-2006 Hygienic Standards for Drinking Water.Results A total of 568 drinking water samples were tested from 2012 to 2018 with a detection rate of 100%.A total of 226 unqualified samples were detected with a qualified rate of 60.21%.The qualified rate of fluoride content in 2015 was the highest(72.83%), while in 2016 the lowest(46.94%).The qualified rate in flood period was slightly higher than that in drought period, which was about 3.12%.The qualified rate of tap water was slightly higher than that of treated water, which was about 0.81%.Conclusion The qualified rate of fluoride in drinking water in Dali County is relatively low.It is still necessary to further strengthen the project of water improvement and fluoride reduction.Water quality safety monitoring also needs to be strengthened so as to ensure the drinking water safety of the public.
