【摘要】：目的了解武汉市居民饮用水碘、砷、氟含量,为有效预防控制碘缺乏病、砷中毒、氟中毒提供科学依据。方法采集所有集中式供水点水源水和末梢水水样各1份;自来水未覆盖的地方,以行政村为单位,按照东、南、西、北、中的方位采集作为饮用水的各类型水源至少1份。水碘检测采用砷铈催化分光光度法,水砷检测采用原子荧光法,水氟检测采用离子选择电极法和离子色谱法。结果全市仅有5个区21个乡(镇、街道)的91个行政村还有分散式供水,占全部行政村的2.85%,其余全部为集中式供水。共采集水样344份,水碘含量为0.00-144.12μg/L,中位数为7.20μg/L,10μg/L的水样197份,占57.27%;水砷含量为0.0005-0.019 mg/L,中位数为0.0005mg/L;水氟含量为0.06-0.81 mg/L,中位数为0.22 mg/L。结论全市未发现高水碘、高水砷和高水氟分布,大部分地区仍然为缺碘地区,应继续实施以食盐加碘为主的综合防控策略,持续消除碘缺乏危害。
[Abstract]:Objective to understand the iodine, arsenic and fluorine contents in drinking water of residents in Wuhan, and to provide scientific basis for the prevention and control of iodine deficiency disorders, arsenic poisoning and fluorosis. Methods one sample of source water and one sample of terminal water were collected from all centralized water supply points, and at least one part of each type of drinking water was collected according to the orientation of the east, south, west and north of the administrative village where the tap water was not covered. Arsenic and cerium catalytic spectrophotometry was used for water iodine detection, atomic fluorescence method was used for water arsenic detection, ion selective electrode method and ion chromatography method were used for water fluorine detection. Results there were only 21 townships (towns, streets) in 5 districts in the whole city. There was a decentralized water supply in 91 administrative villages, accounting for 2.85% of the total administrative villages, and the rest were centralized water supply. A total of 344 water samples were collected, the iodine content of water was 0.00-144.12 渭 g / L, the median of water samples was 7.20 渭 g / L 10 渭 g / L, the median was 57.27; the arsenic content of water was 0.0005-0.019 mg / L, the median was 0.0005 mg / L; the fluorine content of water was 0.06-0.81 mg / L, the median was 0.22 mg / L. Conclusion the distribution of high water iodine, high water arsenic and high water fluoride is not found in the whole city. Most of the areas are still iodine deficient areas. Therefore, the comprehensive prevention and control strategy based on salt iodization should be continued to eliminate the harm of iodine deficiency.
