茂名市水源、尿及食用盐碘含量的调查分析

Investigation of Iodine in Salt,Water and Urine in Maoming

为分析茂名地区居民膳食中碘摄入情况,给碘缺乏病防治提供依据,在所辖区域范围内,对居民饮用水水碘水平、8～10岁儿童尿碘水平、儿童家庭食用碘盐状况等进行了调查。结果表明,共监测27个镇水样128份,碘质量浓度在1.25～195.8μg/L之间,水碘中位值13.5μg/L。8～10岁儿童尿碘中位值为164μg/L,儿童家庭食盐含碘0～51.76 mg/kg,食盐碘与尿碘之间的关系出现不一致性。可见在非高碘地区,碘盐是影响人群营养的重要因素,盐碘应根据饮用水的碘含量而不同,在水碘小于20μg/L的地区盐碘在20～30 mg/kg比较适宜;在水碘为20～150μg/L的地区盐碘在10～20 mg/kg比较适宜。高碘地区应停供碘盐,改水降碘。

To analyze the iodine intake in dietary of residents Maoming city, and provide basis for iodine defieieney disorder prevention and control, iodine in drinking water, urinary iodine of 8 - 10 years old children, status of edible iodized salt in families with children were investigded. The results showed that 128 water samples were in 27 towns, iodine content was 1.25 - 195.8 μg/L, the water median iodine 13.5 μg/L. The median of iodine in urine of children aged 8 - 10 years old were 164 μg/L, salt iodine from families of children 0 -51.76 mg/kg. Alluvial water iodine and jianjiang river between Salt iodine and urinary iodine relationship between the appearance of inconsistency. It conelusdes 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 〈 20 μg/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.
