目的了解淄博市碘缺乏及高碘地区居民饮水含碘量分布现况,指导碘缺乏地区重新划定及科学补碘措施的实施。方法以《山东省实施<食盐加碘消除碘缺乏危害管理条例>办法》划定的8个碘缺乏和1个高碘地区作为调查范围,以自然村为调查单位,采集1～3份饮用人数最多的水源样品。用砷铈催化分光光度法检测水碘。结果采集水样3676份,碘缺乏地区2 996份,水碘中位数2.0μg/L;高碘地区680份,水碘中位数179.60μg/L。碘缺乏地区有64.71%的乡(镇)符合碘缺乏地区划分标准(水碘<10μg/L),26.47%的乡(镇)水碘适中(水碘10～150μg/L),8.82%的乡(镇)为高碘地区(水碘>150～300μg/L)。而高碘地区有9.26%的乡(镇)符合碘缺乏地区划分标准,35.19%的乡(镇)水碘适中,55.56%乡(镇)为高碘地区。结论碘缺乏地区和高碘地区应当采取更进一步细化防治措施;建议不同含碘量食盐供应范围最小单位设定为乡(镇)。
Objective To understand the status of iodine deficiency in drinking water and drinking water iodine content in Zibo, and to guide the redrawing of iodine deficiency areas and the implementation of scientific iodization measures. Methods Eight iodine deficiency areas and one high iodine area delineated by the “Measures for the Administration of Salt and Iodine to Eliminate Iodine Deficiency Hazards” were selected as the survey area. Taking natural villages as the investigation units, 1 to 3 drinking persons were collected most Water samples. Arsenic and cerium catalytic spectrophotometric detection of water iodine. Results A total of 3676 water samples were collected, with 2 996 iodine deficiency areas and a median water iodine concentration of 2.0 μg / L. 680 were iodine - rich areas with a median iodine number of 179.60 μg / L. 64.71% of the townships in the iodine deficiency area met the criteria of iodine deficiency (iodine <10μg / L), 26.47% of township water iodine moderate (water iodine 10 ~ 150μg / L), 8.82% of township (Town) high iodine area (water iodine> 150 ~ 300μg / L). However, 9.26% of townships in high-iodine areas met the criteria of iodine deficiency. 35.19% of rural townships had moderate water iodine and 55.56% of townships were high iodine areas. Conclusion Iodine deficiency areas and areas with high iodine should be further refined prevention and control measures; it is recommended that different iodine content of salt supply minimum unit is set to township (town).
