Based on these graphs of particulate matter concentration recorded in winter and summer seasons, the inflows of dust from the direction of fly ash landfill have been compared for summer and winter periods. This analysis enables to assess the relation of concentrations of pollution from secondary particulate matter suspension to concentrations of pollution generated by other sources. This paper also argues that the 24-hours concentrations, though commonly used, may prove to be an indicator of minor importance to assess air pollution status. On the one hand, excessive 24-hours concentrations impede the identification of the polluter, on the other hand, concentrations generally within permissible limits may occasionally peak dangerously at some sources. As an example, an existing case and a numerical experiment have been presented.}, type={Artykuł}, title={Assessment of Pollution Sources Impact on Pollutants Concentration in Air}, URL={http://journals.pan.pl/Content/124040/PDF-MASTER/5_AE_VOL_27_4_2001_Klis_Ocena.pdf}, keywords={pollutant, concentrations, circular graph of percentiles, source, impact, inflow}, }
