摘要
目的 了解河北平原水源性高碘地区分布特征。方法 采用横断面调查方法，对沧州、衡水、邢台和邯郸市进行调查，在每个调查乡（镇）按照东、西、南、北、中5个方位随机抽取5个村，每个村依据饮用水源数量采取1—5份饮用水样检测含碘量，记录井深。结果 在4个市的65个县（市、区）的729个乡（镇），共采集检测3384份饮用水样本，水碘中位数为27．4μg/L（0．1—2840．4μg／L）。依据国家标准在729个乡（镇）中确定168个高碘地区，占总数的23．05％，大多数高碘地区相连成片。在≥150μgL的水源中，沧州市水井深度与水碘含量成正相关（r=0．43，P〈0．001）。结论 河北平原水源性高碘地区主要分布在河北平原的东南部。这些地区应停止供应碘盐，开展健康教育和水碘监测工作。
Objective To investigate the features of distribution of the areas with excessive iodine in drinking water in Hebei Plain. Methods An epidemiological survey was conducted in 4 regions including Cangzhou, Hengshui, Xingtai and Handan cities by cross section method, which 5 villages were selected according to directions of east, west, south, north and center of each town. Based on the numbers of drinking water source, 1 to 5 samples of drinking water from each village were determined for iodine content, while the depth of the wells were collected. Results A total of 3 384 water samples were collected and determined from 729 townships out of 65 counties in the 4 cities, with median of iodine content being 27.4 μg/L （0.1 - 2 840.4 μg/L）. 168 out of 729 towns were identified as iodine excess areas in line with national criterion, accounting for 23.05% of the total. The iodine excess areas were mainly connected with each other. There was a positive correlation between well depth and iodine content in the drinking water with iodine over 150μg/L in Cangzhou （ r =0.43, P 〈0.001）. Conclusions The iodine excess areas of Hebei Plain were mostly located in the southeast of Hebei Plain. It is suggested that iodized salt supply should be cancdled in these areas, in the meantime health education and water iodine surveillance should be started in the regions.
