摘　　要：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 look into the current distribution of iodine deficiency areas in Zibo city and to guide the re - defined iodine deficiency areas in order to supplement iodine scientifically. Methods 8 iodine deficiency counties （ cities, districts）, and 1 high iodine counties （ cities, districts） were investigated in Zibo city according to＂Supplement iodized salt to eliminate the hazard of iodine deficiency management regulations＂. One to three samples were collected from water source which was used by the majority of local residents in 8 iodine deficiency areas and iodine concentration was tested by As3 ＋ - Ce4 ＋ catalyzing spectro- photometry. Results A total of 3 676 water samples were collected. The median water iodine was 〈 2.0 p,g/L, 64.71% （ 88/ 136） of the township （town） met criteria for the classification of iodine deficiency areas （ water iodine 〈 10 p,g/L）, 26.47% （ 36/ 136） of the township （town） water iodine moderate （ water iodine 10 - 150 μg/L）, and 8.82% （12/136） of the township （town） should be defined as high iodine areas（water iodine 〉 150 -300 μg/L）. However, in high iodine areas, 9.26% （5/54） town-ship （town） met criteria for the classification of iodine deficiency areas, 35.19% （19/54） of the township （town） water iodine moderate, 55.56% （30/54） should be defined as high iodine areas. Conclusions The deficiency and high iodine areas should be taken appropriate measures. The township （town） should be set as the smallest place to supply salt with different range of iodine content.
