摘要
目的了解甘肃省酒泉市生活饮用水水碘含量,为有效防控碘缺乏病提供理论依据。方法2017年在酒泉市7个县(市、区)的92个乡(镇、街道办事处),按不同供水方式(统一集中供水、部分集中供水、分散供水)分层抽样,采集各种水样,测定水碘含量。同时,在泉水和河水作为水源的2个牧业县(肃北县、阿克塞县)以行政村为单位,采集水样,分析不同水源、不同井深水碘含量。根据《碘缺乏病划分标准》(GB 16005-2009),生活饮用水水碘含量<10μg/L可划分为碘缺乏地区。结果在酒泉市7个县(市、区)的92个乡(镇、街道办事处),共调查了273个行政村,采集水样392份,水碘中位数为2.6μg/L,范围为0.1~16.6μg/L,水碘含量<10μg/L的水样372份,占94.90%,≥10μg/L的水样20份,占5.10%。392份水样中,统一集中供水乡水样33份,部分集中供水乡水样311份,分散供水乡水样48份,水碘中位数分别为1.6、2.5、4.3μg/L,3种供水方式水碘中位数比较差异有统计学意义(Z=24.064,P<0.01)。在肃北县和阿克塞县采集水样108份,其中属于地表水水源的泉水与河水水样有64份,水碘含量中位数为5.4μg/L;属于地下水水源的水样44份,水碘含量中位数为5.2μg/L。地表水和地下水水碘含量中位数比较差异无统计学意义(Z=-1.745,P>0.05)。不同井深的水碘含量中位数比较差异有统计学意义(Z=11.113,P<0.05),但均<10μg/L。结论酒泉市不同供水方式、不同水源类型、不同井深水碘中位数均<10μg/L,酒泉市属于外环境严重缺碘地区,碘盐防治碘缺乏病的措施需长期坚持。
Objective To understand the iodine content of drinking water in Jiuquan City,and provide a theoretical basis for effective prevention and control of iodine deficiency disorders(IDD).Methods In 92 townships(towns,streets)of 7 counties(cities,districts)in Jiuquan City,the investigation was carried out in 2017.According to different water supply methods,that was unified centralized water supply,partial centralized water supply,and distributed water supply,stratified sampling method was used to collect water samples,and water iodine content was determined.At the same time,in the two animal husbandry counties of Subei County and Akesai County with spring water and river water as water sources,the administrative villages were taken as units,and water samples were collected to analyze the difference of iodine content in water of different water sources and different wells.According to the"Division Standard for Iodine Deficiency Disorders"(GB 16005-2009),the iodine content of drinking water<10μg/L could be divided into areas of iodine deficiency.Results A total of 392 water samples were collected from 273 administrative villages in 92 townships(towns,streets)in 7 counties(cities,districts)of Jiuquan City.The median water with iodine contents was 2.6μg/L,ranging from 0.1 to 16.6μg/L.And 372 water samples iodine<10μg/L,accounted for 94.90%;20 samples≥10μg/L,accounted for 5.10%.Among the 392 water samples,33 were centralized water supply samples,311 were partial centralized water supply,and 48 were completely distributed water supply.The median water iodine was 1.6,2.5,and 4.3μg/L,respectively.There was a statistically significant difference in the median water iodine between different water supply methods(Z=24.064,P<0.01).In Subei County and Akesai County,108 water samples were collected.Among them,there were 64 water samples with surface water(spring water and river water)as the water source.The median water iodine content was 5.4μg/L.And 44 water samples using ground water as the water source,the median water io
