目的通过调查,了解全市居民饮用水的碘含量,为制定碘缺乏病防治对策提供科学依据。方法采集全市每个村的饮用水样品,以砷铈催化分光光度法检测碘含量。结果共采集3086个村的水样3534份,水碘中位数为3.0μg/L;其中,3431份水样碘含量小于<10.0μg/L;仅有103份水样碘含量≥10.0μg/L,但<150.0μg/L;以区(市)为单位,水碘中位数均<10.0μg/L。结论根据《GB16005-1995碘缺乏病病区划分标准》,枣庄市所辖五区一市均为碘缺乏地区,无局部高碘地区,长期供应碘盐将是控制碘缺乏病的根本措施。
Objective To understand the iodine content of drinking water of residents in the city through surveys to provide a scientific basis for the prevention and control of iodine deficiency disorders. Methods Samples of drinking water in each village of the city were collected, and the content of iodine was detected by arsenic and cerium catalytic spectrophotometry. Results A total of 3534 water samples from 3086 villages were collected and the median of water iodine was 3.0 μg / L. Of these, 3431 samples contained less than <10.0 μg / L iodine and only 103 samples contained more than 10.0 μg / L, but <150.0μg / L. The median of water iodine was <10.0μg / L in districts and cities. Conclusion According to “GB16005-1995 division standard of iodine deficiency disease area”, Zaozhuang city under the jurisdiction of the five districts and one city are iodine deficiency areas, no local high iodine area, long-term supply of iodized salt will be the fundamental measure to control iodine deficiency disorders.
