Abstract:
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 Kazakhstan – the 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.
