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

Currently, high pressure sodium lamps are the light source in greenhouse vegetable growing. The most promising sources of artificial lighting are LED-based irradiators. They can provide a cooler temperature environment to bring plants closer to plants. The aim of the study is to determine the economic life of sodium and LED light sources in greenhouse vegetable growing, taking into account their degradation for the harvest. LEDs, like sodium lamps, degrade during use. This leads to a decrease in the light (photosynthetic photon) flux of light sources and, as a result, to a decrease in yield. Due to this certain functional dependence on the luminous flux level, the economically feasible life of the light is predicted.
