The problem of assessing the city's atmospheric pollution based on monitoring data at stationary observation posts is considered. The results of the research carried out on the example of Iskitim city in the Novosibirsk region are discussed. The analysis of the relationship between the frequency of impurity emissions from dominant sources and the measured concentrations at the stationary observation point of the city for winter periods of time is carried out. The influence of the frequency of winds of different directions on the formation of the level of atmospheric pollution at the control post has been investigated. Taking into account the relative position of the observation point and the main highway of the city, a noticeable contribution of southwestern winds to the increase in benzo (a) pyrene concentrations is shown. The regularities of the formation of atmospheric pollution in calm conditions have been studied. A statistical relationship has been established between the number of calm recorded during the month at the Iskitim meteorological station and the values of benzo(a)pyrene concentrations.
