Abstract

Emissions of heat power facilities affect the air quality and health of the population. The estimation of the volume of particulate matter emissions by these enterprises and the range of their transfer is of great importance. The article presents the results of an estimation of the level of air pollution in the zone of influence of the thermal power plant in Karaganda according to snow survey data. Identified in the study area of man-made air pollution level based on the determination of average daily dust inflow complex with chemical elements of the atmosphere on the snow, as well as man-made structures identified in the solid precipitate snow. It is determined that a very high level of pollution occurs at a distance of 0.5 km from the pipes of the thermal power plant. A tendency has been found to reduce the value of the dust load as far as the distance from the pipes of the thermal power plant is from 0.5 to 2.5 km, which may be related to the particle size and to the process of elution of smaller ash particles by ice dust formed when the water vapor in the smoke jet of the thermal power plant freezes. Data are obtained on the level of accumulation of heavy metals, rare, rare-earth and radioactive elements, as well as the associations of these elements in the solid phase of snow. The study of the real composition of solid suspended particles in air deposited in snow showed that they mainly contain unburnt coal particles, Al-Si microspherules, Fe microspherules and metal-containing particles.
