摘要
目的 为了对碘缺乏病进行科学预防,摸清张家口市饮用水碘分布现状,为今后采取针对性补碘措施提供科学依据。方法 2021年通过调查张家口市集中供水的行政村,分析该供水工程运行情况,并采集1份末梢水水样测定水碘含量;分散供水的行政村,居民饮用水碘调查根据水井数量确定采集水样,测定水碘含量。检测采用砷铈催化分光光度法进行水碘含量分析。结果 调查全市16个县(区)、218个乡(镇)、4 024个行政村(居委会);采集、测定水样4 528份,水样水碘中位数为7.57μg/L,村级水碘中位数为7.94μg/L,乡(镇)级水碘中位数为7.41μg/L,县(区)级水碘中位数为8.42μg/L;水源类型以自来水为主(85.20%)。依据国家标准,本调查只有缺碘和适碘乡(镇),未见高碘乡(镇);县(区)级只有缺碘县(区),未见适碘和高碘县(区);在村级出现极少数高碘村(0.10%,4/4 024)。坝上4县水碘中位数≥40μg/L的占0.36%,坝下12县(区)≥40μg/L的占2.77%,两者比较差异有统计学意义(χ^(2)=29.367,P<0.05);在监测的全部水源类型中,以自来水占比最高(85.20%,3 858/4 528);在供水工程中,其中以2001-2021年建设并开始使用的为主(76.23%,2 941/3 858)。结论 张家口市总体为碘缺乏地区,只发现极少数高碘村。建议对本市普供碘盐的同时对高碘村供应无碘盐,定期开展饮用水源水碘监测。
Objective In order to prevent iodine deficiency disorders scientifically,to find out the present situation of iodine distribution in drinking water in Zhangjiakou City,and to provide scientific basis for taking targeted iodine supplement measures in the future.Methods The operation of the water supply project was analysed by investigating the centralized water supply in the administrative villages in Zhangjiakou City in 2021,and a terminal water sample was collected to determine the water iodine content.In administrative villages with decentralized water supply,the iodine survey of drinking water for residents was based on the number of wells to determine the collection of water samples and the determination of iodine content of water.The test was carried out using arsenic cerium spectrophotometry method for the analysis of iodine content in water.Results A total of 16 counties(districts),218 townships(towns),and 4024 administrative villages(neighborhood committees)in the city were investigated.A total of 4528 water samples were collected and measured,with a median iodine value in water sample water was 7.57μg/L,a median iodine value in village water was 7.94μg/L,a median iodine value of water at the township level was 7.41μg/L,and that of water at the county(district)level was 8.42μg/L.The type of water source was mainly tap water(85.20%).According to the national standards,this survey had only iodine-deficient and suitable-iodine townships(towns)were identified,and no high iodine townships(towns)were found.At the county(district)level,there were only iodine-deficient counties(districts),and there were no suitable or high iodine counties(districts).There were very few villages with high iodine levels(0.10%,4/4024)at the village level.The median iodine value was≥40μg/L in 0.36%of the water in 4 counties on the dam.And≥40μg/L in 2.77%of the water in 12 counties(districts)under the dam,and the difference was statistically significant in the comparison between the two(X^(2)=29.367,P<0.05).Of the total types of water sources monitored,the proportion of tap water was the highest(85.20%3858/4528).Themajority of water supply projects were built and used from 2001 to 2021(76.23%,2941/3858).Conclusion Zhangjiakou City is generally an iodine-deficient region,with only a very few villages with high iodine levels.It is recommended that iodine-free salt should be supplied to villages with high iodine levels as well as the universal supply of iodized salt in the city Iodine monitoring of water in drinking water sources should be carried out regularly.
