The issues of atmospheric pollution, including noise pollution, are considered. The dependences of the concentration of carbon monoxide at distances from the roadway at different directions and speeds of the wind flow obtained according to MRR-2017 are presented. The influence of motor transport on the condition of the air basin and the health of the urban population is considered. The levels of noise pollution in the main-line territories of Volgograd, as well as the main pollutants in the atmospheric air of the main-line territories, are considered. The dispersion of CO concentration at different wind speeds at different angles of wind direction to the road and traffic noise levels depending on the days of the week, time of day, and traffic flow intensity are considered.

Keywords: wind flow direction and speed, roadway, atmospheric air, mainline territories, traffic noise levels, carbon monoxide concentration, vehicle fleet, cargo flow

The influence of road transport on the formation of noise along highways is considered. The proposed options for protecting against noise from the roads.

Keywords: linear city, noise, vehicles, main roads, road categories, noise control

In article metallurgical production as the metallurgy is one of the main sources of technogenic environmental pollution and a working zone is considered. Authors have described the main sources of formation of fine dust by results of which the analysis of fractional structure of the dust particles which are allocated during the operation of the arc melting furnace has been carried out. The submitted data demonstrate that the dust coming to rooms of the shop has the sizes from 3 to 18 microns. The share of mass of particles with sizes less than 10 microns in air of the electrosteel-smelting shop makes from 15%.

At present, more and more attention is being paid to the radiation safety of the population, in connection with this new devices are being modernized and modernized, to improve the state of protection of present and future generations of people from the harmful effects of ionizing radiation for their health. The article considers the key aspects in working with such equipment and suggests measures to reduce the risk of working with it, primarily for personnel, especially in emergency situations.
