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.

Noise pollution of the air is considered to be an excess of the natural level of the background noise or a sharp fluctuation and change in such sound characteristics as the frequency of the sound wave and the strength of the sound stream. The article considers noise levels in the mainline territories in a linear city.

The article raises an urgent problem for large cities - the fight against the negative consequences of road transport. The importance of urban planning measures to reduce the accumulation of emissions, as well as green spaces to reduce the concentration of dust content of harmful substances in urban areas is considered. The data of CO concentration near the mainline territories in 95 studied points were analyzed.

The article discusses the speed and direction of the wind as one of the key factors affecting the spread of carbon monoxide in the linear city of Volgograd. It also investigates the intensity and rolling stock of the traffic flow, which have a negative impact on the pollution of the surface atmospheric layers of the air. Research has been carried out on Raboche-Krestyanskaya street in order to measure the concentration of carbon monoxide on the curb of the roadway.

The article deals with the laws of distribution of pollutants in a linear city. The highest values of carbon monoxide concentration were determined in the near-main territories of the Krasnoarmeysky district of Volgograd. Also in this paper, the question of the dependence of the level of gas pollution in the mainline areas on various factors, which include human activity and natural, natural factors, is raised. The influence of temperature inversions on the speed of pollution propagation and their limiting value in various points of the city is considered. For the experimental part, 18 points of technical measurements of CO concentration were taken, during which compliance with the MPC standards of the samples taken was revealed.

In this article is reviewed the nature of organic hybrid nanocomposites. Promising directions in the field of organic hybrid nanocomposite materials will be methods for the synthesis of multicomponent materials, as well as the type of "net net" and "host-guest". The fundamental problem with the chemistry and physics of nanocomposites is dependent "structure-property". Solving this problem will move from research materials to their purposeful design.

Keywords: nanocomposite sol-gel technology, synthesis, nanoparticles.
