摘　　要：目的掌握海南省外环境居民生活饮用水碘含量分布状况,为因地制宜、科学补碘提供科学依据。方法2017年,在海南省所有市(县、区),以乡镇为单位,根据其不同供水方式采集水样检测碘含量;水碘中位数> 10 μg/L的乡镇,以行政村(居委会)为单位采集水样检测碘含量。按照地理位置(中部山区、东部沿海、西部沿海),水源类型(自来水、插管井、泉水),井深等进行水碘分布状况分析。结果全省21个市(县、区)共检测水样2 566份,水碘中位数为6.0 μg/L,范围为0.1 ~ 150.6 μg/L,各市(县、区)水碘中位数均< 10 μg/L。中部山区、东部沿海、西部沿海地区的水碘中位数分别为3.3、6.5、6.5 μg/L,自来水、插管井和泉水3种水源的水碘中位数分别为5.6、6.4、1.3 μg/L,0 ~、100 ~、200 ~、≥300 m井深的水碘中位数分别为6.6、5.1、4.2、1.5 μg/L。全省230个乡镇水碘含量范围为0.2 ~ 17.9 μg/L,水碘中位数> 10 μg/L的有12个乡镇,包含133个行政村(居委会),共检测水样737份,村级水碘含量范围为1.0 ~ 37.1 μg/L。结论海南省各市(县、区)均属于碘缺乏地区,中部山区更为严重,且全省大多数乡镇外环境处于缺碘状态,未发现高碘行政村(居委会),全省应继续实行食盐加碘防治碘缺乏病的防治策略。Objective To grasp the distribution of iodine in drinking water in the environment of Hainan Province, and provide scientific basis for prevention and treatment of iodine deficiency disorders. Methods In 2017, in all cities (counties, districts) in Hainan Province, townships were used as units to collect water samples to detect iodine content according to their different water supply methods. In the townships with median drinking water iodine > 10 μg/L, the administrative village (neighborhood committee) was used as a unit to collect water sample to detect iodine content. According to the geographical location (central mountainous area, eastern coast, western coast), water source type (tap water, intubation well, spring water), and well depth, the distribution of water iodine was analyzed. Results A total of 2 566 water samples were detected in 21 cities (counties, districts), the median water iodine was 6.0 μg/L, range was 0.1 - 150.6 μg/L, the median water iodine of all cities (counties, districts) was < 10μg/L. The median water iodine in the central mountainous area, eastern coast, and western coast were 3.3, 6.5, 6.5 μg/L, respectively;tap water, intubation well, and spring water were 5.6, 6.4, 1.3 μg/L, respectively;0 -, 100 -, 200 -,≥300 m well depth were 6.6, 5.1, 4.2, and 1.5 μg/L, respectively. The water iodine content range was 0.2 - 17.9 μg/L in 230 townships in the province, there were 12 townships with the median water iodine > 10 μg/L, including 133 administrative villages (neighborhood committees), and 737 water samples were detected, the water iodine content range was 1.0 - 37.1 μg/L. Conclusions All cities (counties, districts) in Hainan Province belong to iodine deficiency areas, the central mountainous area is even more serious. Most of the townships in the province are in iodine deficiency. No administrative villages (neighborhood committeea) with high iodine have been found. The province should continue to implement salt iodization to prevent and treat iodine deficiency disorders.
