The technology of mapping of environmental risks during the transfer and transformation of pollutants emitted into the atmosphere of the city by stationary facilities is considered. The technology is implemented on the example of the pollution of the air basin of the city of Almaty with sulfur dioxide SO2by heat power enterprises. The calculations were made using the WRF-Chem model, previously adjusted to the city atmosphere by parametrizing of microphysical processes and comparing them with observational data at meteorological stations in the city and the surrounding area. Risk maps were constructed according to a variety of impurity concentrations for various meteorological conditions. The following risk measures were used: the mathematical expectation with the exclusion of unlikely bursts of high concentrations (less than 1%) and the recurrence of cases of exceeding of the maximum one-time MPC. The technology can serve as the basis of an information and analytical system for solving of various tasks concerning location of enterprises and the analysis of plans for air protection measures.
