Detection and analysis of iodine content of drinking water in Jingdezhen Municipality / 中国现代医生

ABSTRACT

Objective Iodine is a necessary microelement in human body. The major way for people to obtain iodine is drinking water. In this study, the drinking water is well water. We detected and analyzed the iodine content in drinking water. Methods The drinking water tested in Jingdezhen from March to October 2017 was selected, and 186 of these samples were used as the object of this study. All the objects were representative of the geographical conditions and population distribution of the city. Samples of drinking water were tested using the method recommended by the National Iodine Deficiency Disorders Laboratory of Chinese Center for Disease Control and Prevention (ie, spectrophotometry method with cerous sulfate). Results The iodine content ranged from 5-127. 66 μg/L, with 76 samples ＜10 μg/L accounting for 40. 86％, and 110 samples ≥ 10 μg/L accounting for 59. 14％. Conclusion The iodine content of drinking water in Jingdezhen can meet the needs of the human body. However, in some drinking water, the iodine content is relatively insufficient and it is necessary to use iodized salt to supplement the physical needs.
