The aim of the work is to assess the contribution of vehicle emissions to air pollution of the Irkutsk agglomeration, on the example of a large industrial and transport city of Angarsk. In order to achieve the goal, emission calculations were carried out on the basis of field surveys of the composition and traffic intensity of vehicles at major intersections of Angarsk during peak hours. With the help of the program complex «Ecologist» calculations of concentrations of the main harmful substances emitted into the atmosphere by vehicles were carried out.

The aim of the work is to assess the contribution of emissions from forest fires to air pollution using the example of the territory of the Pribaikalsky National park. To achieve this goal, calculations of gross emissions were carried out based on forestry data on fires. With the help of the program complex «Ecologist» calculations of concentrations of impurities emitted into the atmosphere during forest fires were carried out. Based on the results of the calculations, maps of the concentrations of pollutants released into the atmosphere from fires were created.
