What are the incorrect choices of main prevention and control measures in areas with high iodine content in water sources?

Everyone knows that iodine deficiency is harmful to health, but many people don't know that excessive iodine intake is also harmful to health. If the iodine intake exceeds the body's needs for a long time, it may lead to iodine goiter, hyperthyroidism, hypothyroidism and autoimmune thyroiditis in severe cases.

There are two reasons for high iodine: water source and food source. Japan is the first country to find food-borne goiter with high iodine, which is mainly caused by eating too much seaweed products. In China, water-based high iodine is the most, such as some towns in Weinan City, among which Liuji Town in Fuping County is the most significant.

"Areas" and "Endemic Areas" with High Iodine Content in Water Sources

High iodine water source areas can be divided into two types according to the degree of high iodine and whether it causes iodine deficiency: high iodine water source areas and high iodine water source areas.

(1) Water-based high iodine area: In a specific natural environment, people consume too much iodine through drinking water for a long time, but it is not enough to cause diseases such as iodine goiter.

(2) Water-based areas with high iodine: In a specific natural environment, people consume excessive iodine through drinking water for a long time, causing diseases such as goiter with high iodine.

Distribution of "endemic areas" and "districts" with high iodine in water sources in our city

At present, the water-borne high iodine endemic areas in our city are mainly distributed in Liuji Town 15 village, Fuping County, and the water-borne high iodine endemic areas are mainly distributed in Linwei District, Weinan Economic Development Zone, Weinan High-tech Zone, Dali County, Fuping County, huayin city and other five counties (cities, districts) 109 village.

Main measures to prevent and control the harm of high iodine

1, non-iodized salt is supplied by the salt industry department.

2, the water conservancy department should implement water improvement measures, turn high iodine drinking water into iodine-containing drinking water.

3, health, education, publicity and other departments * * * to do a good job in health education, let the people know to buy salt, not only to ensure the supply of iodized salt for residents in drinking water areas with high iodine, but also to prevent the impact of iodized salt on iodine-deficient areas.

4. The health department should establish and improve an effective monitoring system, timely grasp the supply of iodized salt, the change of water iodine and the condition of high iodine areas, and appropriately adjust the prevention and control strategies according to the monitoring results.
