目的全面掌握衡水市居民生活饮用水水氟含量现状及分布情况,为有效防治地方性氟中毒提供科学依据。方法 2012年3~9月在衡水市以行政村为单位,采集每个村饮水水源水样,集中供水采集1份水样,分散供水按东、西、南、北、中方位采集5份水样,测定水氟含量,以水氟平均值代表该村饮水氟含量。结果共调查水源4 166个,覆盖全市13个县市区、5 010个行政村,全市中、西、北部地区(深州、武强、饶阳、安平、桃城区、开发区、滨湖新区)水氟值<1.0 mg/L的1 348个村,占总行政村数的88.3%;水氟值>1.0 mg/L的178个村,占总行政村数的11.7%。东、南部地区(故城县、景县、阜城县、武邑县、枣强县)水氟值<1.0 mg/L的658个村,占总行政村数的18.9%;水氟值>1.0 mg/L的2 826个村,占总行政村数的81.1%。结论衡水市中、西、北部地区绝大部分水氟值<1.0 mg/L,达到国家饮水卫生标准,而东、南部地区受高氟危害较为严重。
Objective To comprehensively grasp the current situation and distribution of fluoride content in drinking water of residents in Hengshui City and provide a scientific basis for the effective prevention and treatment of endemic fluorosis. Methods From March to September 2012, Hengshui city took the administrative village as the unit, collected the water samples of drinking water in each village, collected 1 water sample from the centralized water supply and distributed 5 samples of water according to the east, west, south, north and middle of the scattered water supply Like, determination of water fluorine content, water fluoride on behalf of the average fluoride content of the village water. Results A total of 4,166 water sources were surveyed, covering 13 cities and counties in the city, 5,010 administrative villages, and the central, western and northern regions of China (Shenzhou, Wuqiang, Raoyang, Anping, Taocheng, Development Zone, Binhu New District ) 1 348 villages with water fluoride value <1.0 mg / L accounted for 88.3% of the total administrative villages; 178 villages with water fluoride value> 1.0 mg / L accounted for 11.7% of the total administrative villages. 658 villages with water fluoride value <1.0 mg / L in Gucheng County, Jing County, Fucheng County, Wuyi County and Zaoqiang County, accounting for 18.9% of the total number of administrative villages in the eastern and southern areas (Gucheng County, Jingxian County, Fucheng County, Wuyi County and Zaoqiang County) The 2,826 villages at 1.0 mg / L accounted for 81.1% of the total administrative villages. Conclusion Most of the waters in the middle, west and north of Hengshui City have a water fluoride value of <1.0 mg / L, which meets the national standard of drinking water hygiene. However, the damage caused by high fluoride in the eastern and southern regions is more serious.
