The lists of the main sources of soil pollution on the territory of Uzbekistan are determined by a complex of national economic, socio-economic, soil-climatic and sanitary-hygienic local conditions that have developed in connection with the development of agriculture and industry, the organization of sanitary cleaning of populated areas of the republic. The current state of the soil is alarming because over the past 30-50 years the soil has been subject to salinization, water and wind erosion, and contamination with heavy metals, fluorides and agrochemicals.

Most of the selected soil samples did not meet hygienic requirements in terms of bacteriological indicators. Other indicators: i.e. the amount of pesticides, salts of heavy metals and radioactive substances, the number of helminths in all soil samples met the hygienic requirements
