The article presents examples of synoptic situations when the permissible concentration of PM10 was severely exceeded in 2010–2017 in Poznań. In many Polish cities, there are deviations from the norms for a number of days during the year. The scale of concentration of PM10 in the air is largely affected by the prevailing meteorological conditions such as low temperature and low wind speed. First, periods of the highest daily concentrations of pollutants were selected. Subsequently, synoptic maps for selected days were analysed. The most common cause of the pollution was a large boom which brought Arctic air to Poland. In this case, the highest concentration was accompanied by very low air temperatures and the resulting more intensive heating of buildings.

The subject of the paper is the influence of atmospheric circulation on the content of suspended PM10 in the air in Konin. For this purpose dust concentrations from the period 2012–2016 were generally characterized. PM10 particulate matter concentration average hourly data were obtained from the Main Inspectorate of Environmental Protection website. Based on these data, long-term, seasonal and daily changes in the PM10 concentration in the atmosphere were investigated. The study analysed the daily variability of the PM10 suspended particulate matter concentration to present seasonal differences (in hot and cold seasons). In order to determine the influence of atmospheric circulation on the PM10 particulate matter concentration, the concentration levels data were compared with the types of circulation prevailing on the same day. In this study according to synoptic maps the days with maximum and minimum concentrations PM levels were analysed. It was found which type of meteorological circulation is conducive to higher levels concentrations of particulate matter PM10, and which has a positive effect on the quality of the air in Konin.
