The endemic goitre is a popular disease affecting hundreds of millions of worldwide patients. This disease affects human being in many aspects, including: bad body development, nervous system, down disease, and some other diseases related to the lack of iodine like endemic goitre.

For over ten years, the National Program on Iodine defficiency prevention and protection has been carried out on the whole country and achieved some results. The epidemic investigation in some regions, actually, has shown the goitre rate still ranging from light to average levels. This leads to some doubt that the goitre there might be caused by other reasons.

Studies on the features of geochemical environment and endemic goitre in some regions have shown that the reasons causing local goitre is not only iodine defficiency, but also other factors of geochemical environment, in which some elements might prevent the synthesizing capacity of iodine component in thyroid gland. Studies on the relation between geochemical environment and goitre in different ecological regions have been initially defined and proposed some appropriate methods for the prevention and protection from iodine deficiency disease in different ecogeoechemical systems on the country.
