摘要
目的了解福州市生活饮用水碘含量和分布情况,为基层开展碘缺乏病的防治工作和健康干预提供依据。方法2017年,在福州市辖内12个县(市、区)以乡镇为单位开展水碘调查,并对水碘中位数≥10μg/L的乡镇开展行政村级水碘调查,按照不同供水方式(集中供水、混合供水和分散供水)采集居民生活饮用水末梢水水样并测定水碘含量,水碘含量<10μg/L为外环境缺碘;对不同地区、不同供水方式和不同水源类型的居民生活饮用水碘含量进行比较分析。结果共对12个县(市、区)的172个乡镇进行了调查,采集并检测水样1630份,水碘中位数为2.8μg/L,范围为0.0~130.3μg/L;在乡镇水平上,水碘中位数范围为0.4~11.2μg/L;在≥10μg/L的4个乡镇共调查了75个行政村,水碘中位数范围为0.5~19.8μg/L;在县(市、区)水平上,水碘中位数均<10μg/L。其中,内陆地区和沿海地区水碘中位数分别为2.0、4.0μg/L,不同地区间比较差异有统计学意义(Z=-15.70,P<0.01);集中供水、混合供水和分散供水的水碘中位数分别为4.1、2.7、3.4μg/L,不同供水方式间比较差异有统计学意义(H=19.38,P<0.01);地表水和井水水碘中位数分别为2.4、3.1μg/L,不同水源类型间比较差异有统计学意义(Z=-6.23,P<0.01)。结论福州市外环境缺碘普遍存在,不存在水源性高碘分布。要加强碘缺乏病的监测,建立与经济社会发展水平相适应的长效工作机制,巩固防治成果。
Objective To understand the level and distribution of iodine contents in drinking water in Fuzhou City so as to provide evidence for prevention of iodine deficiency disorders and health intervention.Methods In 2017,a township-level water iodine survey was carried out in 12 counties(cities,districts)under the jurisdiction of Fuzhou City,with a township as a unit,and carry out administrative village-level water iodine survey in township with the median water iodine≥10μg/L.The water samples of residents'drinking water were collected according to different water supply methods(centralized water supply,mixed water supply and decentralized water supply),and the water iodine content was determined.The water iodine content less than 10μg/L means iodine deficiency in the external environment.The iodine contents in drinking water of residents in different areas,different water supply methods and different water source types were compared and analyzed.Results A total of 172 townships in 12 counties(cities,districts)were investigated for water iodine,and 1630 water samples were collected and tested,the median water iodine was 2.8μg/L and the range was 0.0-130.3μg/L.At the township-level,the median range of water iodine was 0.4-11.2μg/L.A total of 75 administrative villages were investigated in 4 townships with a median water iodine≥10μg/L,the median water iodine range was 0.5-19.8μg/L.At the counties(cities,districts)level,the medians of water iodine were all less than 10μg/L.Among them,the medians of water iodine in inland areas and coastal areas were 2.0 and 4.0μg/L,respectively,and the difference between different areas was statistically significant(Z=-15.70,P<0.01).The medians of water iodine for centralized water supply,mixed water supply and decentralized water supply were 4.1,2.7,and 3.4μg/L,respectively,and the difference between different water supply methods was statistically significant(H=19.38,P<0.01).The medians of water iodine in surface water and well water were 2.4 and 3.1μg/L,respectively,the
