The article considers examples of atmospheric air monitoring in linear and compact cities. The issues of atmospheric air pollution are considered, examples of components of pollutants coming from stationary and mobile sources are given. The analysis of the monitoring system of cities with different urban planning is carried out.

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 forecast of fine dust pollution, the organization of monitoring and quality control of the air environment are relevant for cities with a developed transport infrastructure. The article checks the application of the distribution law for the concentration of fine dust PM2.5 and PM10 for highways of urban, district and local significance, the sample size was 50 values.

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 considers a number of the most significant factors affecting the dispersion of pollutants in the air. The influence of meteorological conditions on the dispersion of pollutants in the atmospheric air by various methods of calculating the dispersion is considered.
