摘要
目的了解全国外环境水碘的分布情况,为因地制宜防治碘缺乏病提供背景资料。方法各省在每个地级行政区划单位随机抽取3个县,每个县随机抽取1～3个行政村,全省总数不少于30个。每个行政村采集不同饮用水源的水样进行检测碘水平。结果16个省份的水碘中位数< 5.0 μg/L,24个省份的水碘中位数< 10 μg/L,在4个省份发现了水碘> 200 μg/L的县。结论全国缺碘地区广泛存在,高碘地区范围不明确,急需查清。
Objective To clear the environmental iodine level and its distribution in China, so that providing the background materials for suiting measures to local conditions to control iodine deficiency disorders. Methods In each province, 3 counties were selected at random in each prefecture, 1～3 villages were selected at random, total 30 village were selected. Water samples of different drinking water sources were collected from these villages and water iodine was determined. Results There were 16 provinces whose median water iodine was lower than 5.0 μg/L, and 24 provinces lower than 10 μg/L. We also found some counties in 4 provinces whose water iodine was greater than 200 μg/L. Conclusions In our country, there are still many areas lacking iodine. Because the range of high iodine districts in China are not clear, we should investigate it quickly.
