Особенности проявления йододефицита на территории Республики Беларусь

A medium-scale map of iodine deficiency in the territory of the Republic of Belarus was created for the first time. The map characterizes in detail a spatial variation of iodine concentration in soils of Belarus. The article analyzes a spatial specificity of the ecological situation formed as a result of heterogeneity of the iodine content in soils. Using the means of a specialized GIS, the area of high iodine deficiency was identified at the level of administrative regions. The identified area was further differentiated in terms of different level of ecological risk due to a natural soil iodine deficiency. As a result of such geoinformation analysis, the areas of moderate, significant and greatest risks were established in the territory of Belarus. These regions should become the objects of high priority monitoring and are directly in need of targeted preventive measures.
