In the context of the growing ecological crisis caused by climate change, irrational use of water resources and environmental pollution with dangerous pollutants, an important role is played by assessing the role of environmental damage from crop production.The authors analyzed the environmental compatibility of modern rice production in the main rice growing region in the Republic of Kazakhstanthe Kyzylorda region.The work included theoretical calculations of methane greenhouse gas emissions throughout the region for the entire vegetative season.And also calculated the costs of water resources for irrigation of rice fields, including water leaving for evaporation from the water surface, evapontranspiria, saturation of the soil, filtration flow and outflow into the drainage network.In the grain of rice varieties "Aikerim" and "Favorit" grown in the Kyzylorda region, residual amounts of such toxic substances as organochlorine pesticides (HCH α, β, γ-isomers, DDT, DDE) were determined.Heavy metals (cadmium, lead, arsenic and mercury) were also determined in these varieties of rice.
