- It is a common belief that atmospheric air pollution increases in a period of low temperatures due to higher energy demand. The evaluation of dust pollutants immission that spread into atmosphere can be made on the basis of real measurements of the quantity of pollutants in the air. The variability of dust contents in the air in time and space causes the measurements results to have temporary character. The uniformed methodology of determining dust concentration levels allows a general evaluation of the scale of phenomena and tendencies as well as the dynamics of changes occurring in the city agglomeration air. In Poland dust is emitted in very close ratios from the sectors of power engineering, industry and municipal. The total emission of particulate matter is very big and despite its considerable reduction in recent years Poland still remains one of the main dust emitters in Europe. The reason for this is a dominant role of coal as an energy carrier, high energy demands of national economy as well as huge shares of extractive industry and metallurgy in economy. The paper presents the results of research concerning the determination of distribution of suspended particulate matter concentration (PM10) over the area of the city Lublin. The analysis referred to diurnal measurements in an annual cycle for the years 2002-2005. It contains the results of PM10dust measurements in the following measurements points: Maszynowa, Obywatelska and Spokojna Streets. On the basis of the analyses carried out it is possible to draw the following conclusions: 1. The results obtained from conducted analyses of air pollution monitoring as well as the results of author's own research clearly showed the seasonal changes (warm season, cold season) in suspended particulate matter concentrations (PM10). The concentrations of PM10 dust are considerably higher in the cold season. 2. The distribution of the concentrations of pollution examined in the seasons of particular years showed that in the case of concentrations of suspended particulate matter PM10 in the period in question, the cold seasons are characterized by increased suspended dust concentrations (PM10) in relation to the warm seasons in each particular measurement points. 3. The tendency of the increase in PM10 dust concentration levels can be explained by the increase in the number of cars. Over the last years especially that the past years examined are characterized by a rather considerable reduction in the number of industrial factories which are the source of pollution emission. 4. Between 2002-2005 there were recorded the cases of exceeding the permissible diurnal levels of PM10 dust concentrations.
