摘  要:目的了解三亚市育才生态区居民饮用水水碘含量及分布情况,为推进科学补碘提供依据。方法 2017年9月按照《全国外环境水碘分布调查方案》在全区以行政村为单位开展居民生活饮用水水碘含量调查。采用分散供水采样方法,将每个行政村分成东、西、南、北、中5部分,每部分随机抽取2口井。水碘检测采用电感耦合等离子体质谱法。结果全区共调查10个行政村,其中饮用浅井水的行政村6个,饮用泉水的行政村4个。共采集水样100份,其中浅井水60份、泉水40份。全区水碘在1.8~191.4μg/L之间,水碘中位数为5.9μg/L,全区10个行政村只有2个行政村水碘中位数在10.0~100.0μg/L,其余行政村水碘中位数均小于10.0μg/L。100份水样中水碘在10.0μg/L以下的比例为62.00%,10.0~100.0μg/L比例为36.00%,高于100.0μg/L水碘比例为2.00%。浅井水碘中位数高于泉水水碘中位数(P<0.05)。浅井井深和水碘含量之间无相关性(P>0.05)。结论育才生态区生活饮用水水碘含量总体上处于较低水平,无高碘地区,大部分地区属于碘缺乏地区,需继续实施食盐加碘的综合防治措施。相关部门应积极做好科学补碘宣传教育工作,提高居民科学补碘意识,做好人群碘营养水平及水碘动态监测工作,推动科学补碘。Objective To understand the iodine distribution in residents’ drinking water in Yucai ecotope in order to provide evidence for scientific iodine supplementation.Methods An investigation on iodine contents in residents’ drinking water was carried out based on the unit of administrative village according to the Investigation Plan of Iodine Distribution in Environmental Water in the Country in September, 2017. Dispersed water sampling method was adopted. The water samples were randomly collected in two wells of five parts of an administrative village(on the direction of east, west, south, north, and central parts). Inductively coupled plasma mass spectrometry was used to test water iodine.Results A total of 10 administrative villages were investigated, in which 6 administrative villages drank shallow well water and the other 4 administrative villages drank spring. A total of 100 water samples were collected in including 60 shallow shaft samples and 40 spring samples. The water iodine was between 1.8 μg/L and 191.4 μg/L, and the median was 5.9 μg/L. The median of water iodine content was between 10.0 μg/L and 100.0 μg/L in 2 administrative villages among 10 administrative villages in Yucai ecotope, and other villages water iodine median was less than 10.0 μg/L. Among the 100 water samples, the proportion of the water iodine less than 10.0 μg/L was 62.00% and the proportion of the water iodine between 10.0 μg/L and 100.0 μg/L was 36.00%, and the proportion of the water iodine higher than 100.0 μg/L was 2.00%. The median of water iodine content in the shallow shift water samples was higher than that in the spring water samples(P<0.05). There was no correlation between the depth of shallow shift and water iodine content(P>0.05).Conclusion On the whole the iodine content of drinking water in Yucai ecotope is on the low level, there is no high iodine area, and most areas belonged to iodine deficiency area,comprehensive control measures of salt iodized should be implemented continually.
