Abstract:
The hazards of water-borne iodine excess is a relatively serious public health problem in China. The government has made great progress in prevention and controlling of the hazards of water-borne iodine excess through measures such as supplying non-iodized salt and implementing measures such as improving water quality to decrease iodine. However, there is a lack of corresponding evaluation criteria for measuring the implementation level and effectiveness of prevention and control measures, which urgently needs to be addressed. This article explores the technical indicators for establishing control standards for water source high iodine hazards in China through a review and analysis of relevant laws and regulations, normative documents, standards, and research progress in the field of high iodine prevention and control at home and abroad. It is recommended that administrative villages be used as units to evaluate the control status of water source high iodine hazards; after water improvement and iodine reduction, the iodine content of residents' drinking water should be ≤100 μg/L; meanwhile, the median urinary iodine for school-age children should be between 100 and < 300 μg/L, thyroid enlargement rate should be less than 5%.
