The Astrakhan gas processing complex, LUKOIL enterprises, a number of military polygons and a motor vehicle port belong to the number of the main enterprises that pollute the atmospheric air. In addition, there are a number of large shipbuilding and repair plants in the region, which are also sources of pollutant emissions. A characteristic feature of the processed gas condensate on the Astrakhan gas processing complex is a high content of hydrogen sulfide. The aim of the study is to study the state of atmospheric air in various areas of Astrakhan and the region in order to reveal the dynamics of the state of atmospheric air, depending on the time of year. The nature of air pollution is determined by the density of location of industrial zones in Astrakhan and the Astrakhan region, as well as by the specifics of enterprises. The effect of the seasonal factor on the change in the monitored indicators was found. As a rule, during the summer period, the content of pollutants in the atmospheric air is increased, this, apparently, is associated with higher average monthly temperatures and lower humidity of air, as well as more intensive operation of transport. In zones with an increased content of harmful substances in the air, it is advisable to conduct constant monitoring of these substances.
