摘　　要：目的 了解山东省碘缺乏地区居民饮水含碘量分布现况,指导碘缺乏地区的重新划定及科学补碘措施的实施.方法 2008年以〈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100个碘缺乏县（市、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.结果共收集水样65 716份,回收样品有效率达到99.8%（65 572/65 716）,水碘中位数为5.57μg/L.有82.05%（1097/1337）的乡（镇）符合碘缺乏地区划分标准（水碘＜10 μg/L）,17.43%（233/1337）的乡（镇）水碘适中（水碘10～150μg/L）,0.52%（7/1337）的乡（镇）为高碘地区（水碘＞150～300μg/L）.结论碘缺乏地区居民饮水含碘量发生改变,需进行重新界定;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 area in Shandong province and to guide the re-defined iodine deficiency area and to supplement iodine scientifically. Methods In 2008, 100 iodine deficiency counties（cities, districts）, designated in Shandong province＇s ＂to supplement iodized salt to eliminate the hazard of iodine deficiency management regulations＂, were selected in the study. One to three samples were collected from water source which was used by the majority of local residents in the 100 iodine deficiency places and iodine concentration was tested by As3＋-Ce4＋ catalyzing spectrophotometry. Results A total of 65 716 water samples were collected. Sample recovery efficiency reached 99.8%（65 572/65 716）. The median water iodine was 5.57 μg/L, with 82.05%（ 1097/1337 ） of the township（town） met criteria for the classification of iodine deficiency areas（water iodine 〈 10 μg/L）, 17.43%（233/1337） of the township （town） water iodine moderate（water iodine 10 - 150 μg/L）, and 0.52%（7/1337）of the township（town） should be defined high iodine areas（water iodine 〉 150 - 300 μg/L）. Conclusions The iodine deficiency areas should be redefined because water iodine concentrations of iodine deficiency areas have changed. We suggest that the smallest place to supply salt with different range of iodine content is set to the township（town）.
