摘要
目的了解不同的水碘地区人群碘营养状况,食用盐盐碘含量,为科学补碘提供依据。方法每个乡(镇)按东、西、南、北、中不同的方位随机抽取5个村,每个村依据水源数量抽取1～5份饮用水样,测定水碘含量;不同的水碘地区(水碘值<10μg/L、10～μg/L、20～μg/L 7、5～μg/L1、50～μg/L3、00～μg/L、600～μg/L)随机抽取3～5个乡200名以上(男、女各半)8～10岁儿童测定尿碘含量,每个乡随即采取儿童家庭食用盐40份,测定盐碘含量;在水碘值150μg/L以下的乡,随机抽取育龄妇女20名测定尿碘含量;水碘和尿碘浓度检测采用砷铈催化分光光度测定法,盐碘含量检测采用直接滴定法。结果共监测190个乡(镇)水样919份,碘含量在0.15～2840.4μg/L之间,水碘中位数66.38μg/L。水碘值<10μg/L、10～μg/L 2、0～μg/、75～μg/L、150～μg/L、300～μg/L、600～μg/L地区的儿童尿碘中位数、儿童家庭食用盐碘中位数分别是:174.38μg/L、25.41㎎/㎏;145.22μg/L7、.45㎎/㎏;229.58μg/L、16.50㎎/㎏;197.44μg/L、4.45㎎/㎏;257.26μg/L8、.21㎎/㎏;388.40μg/L、3.83㎎/㎏;1506.30μg/L、0㎎/㎏;水碘值<10μg/L、10～μg/L、20～μg/7、5～μg/L地区的育龄妇女尿碘中位数分别是139.61μg/L、131.22μg/L2、25.53μg/L、192.42μg/L。结论在非高碘地区,碘盐是影响人群碘营养的重要因素,盐碘浓度应根据饮用水的碘含量而不同,在水碘小于20μg/L的地区盐碘浓度在20～30㎎/㎏比较适宜;在水碘为20～150μg/L的此区盐碘浓度在10～20㎎/㎏比较适宜。高碘地区应停供碘盐,改水降碘。
Objective Understand people＇s nutrition status of iodine in the different areas of water iodine,iodine salt,edible salt,in order to provide the basis for science.Methods Each township（town） on east,west,south,north,in different directions randomly selected five villages,each village based on the number of water sources of drinking water taken from 1 to 5 samples were measured iodine content of water;different areas of water iodine（water iodine value 10 μg/L,10~μg/L,20~μg/L,75~μg/L,150~μg/L,300~μg/L,600~μg/L） were randomly selected 3 to 5 townships,200 or more（men and women female） children aged 8 to 10 for urinary iodine content measurement,then each township 40 salt samples in families with children to determine iodine content of salt;in towns water iodine value below 150 μg/L,randomly selected 20 women of childbearing age for urine iodine determ in ation;water iodine and urine iodine concentration were detected by arsenic Ce catalytic spectrophotometry,salt iodine content was determined by direct titration. Results 919 water samples were monitored in 190 townships（towns）,iodine content was 0.15~2 840.4 μg/L,the water iodine 66.38 μg/L.In areas water iodine value 10 μg/L,10~μg/L,20~μg/L,75~μg/L,150~μg/L,300~μg/L,600~μg/L,the median of urinary iodine in children and that of household iodized salt were 174.38 μg/L,25.41 mg/kg;145.22 μg/L,7.45 mg/kg;229.58 μg/L,16.50 mg/kg;197.44 μg/L,4.45 mg/kg;257.26 μg/L,8.21 mg/kg;388.40 μg/L,3.83 mg/kg;1 506.30 μg/L,0 mg/kg;in areas water iodine value 10 μg/L,10~μg/L,20~μg/L,75~μg/L,urinary median iodine in women of childbearing age were 139.61 μg/L,131.22 μg/L,225.53 μg/L,192.42 μg/L. Conclusions In non-iodine areas,iodized salt was an important factor for iodine nutrition,the concentration of salt iodine content in drinking water should be based on the different iodine in water.In areas water iodine 20μg/L,salt iodine concentration of 20~30 mg/kg was appropriate;In areas water iodine between 20 and 150 μg/L,salt iodine concentration of 10~20 mg/kg was appropriate.Iodized salt in high iodine areas should be stopped and reduced iodine by changing water.
