【摘要】：目的了解武漢市居民飲用水碘、砷、氟含量,為有效預(yù)防控制碘缺乏病、砷中毒、氟中毒提供科學(xué)依據(jù)。方法采集所有集中式供水點(diǎn)水源水和末梢水水樣各1份;自來(lái)水未覆蓋的地方,以行政村為單位,按照東、南、西、北、中的方位采集作為飲用水的各類(lèi)型水源至少1份。水碘檢測(cè)采用砷鈰催化分光光度法,水砷檢測(cè)采用原子熒光法,水氟檢測(cè)采用離子選擇電極法和離子色譜法。結(jié)果全市僅有5個(gè)區(qū)21個(gè)鄉(xiāng)(鎮(zhèn)、街道)的91個(gè)行政村還有分散式供水,占全部行政村的2.85%,其余全部為集中式供水。共采集水樣344份,水碘含量為0.00-144.12μg/L,中位數(shù)為7.20μg/L,10μg/L的水樣197份,占57.27%;水砷含量為0.0005-0.019 mg/L,中位數(shù)為0.0005mg/L;水氟含量為0.06-0.81 mg/L,中位數(shù)為0.22 mg/L。結(jié)論全市未發(fā)現(xiàn)高水碘、高水砷和高水氟分布,大部分地區(qū)仍然為缺碘地區(qū),應(yīng)繼續(xù)實(shí)施以食鹽加碘為主的綜合防控策略,持續(xù)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.
