The measurements of 24- hour N02 concentrarion were made by spectrophotometric method with passive sampling in 20 sites in the period of 2 years. The results were analysed by statistical methods, such as: analysis of variance and correlation. The 24-hour NO, concentration has significant spatial variation in the area of Cracow. The highest values were measured in the street canyons, the lowest in residential areas. The highest values of N02 concentration were observed during heating season. The results of passive method are comparable with the results of authomatic method and because of this both methods may be use together in monitoring networks.}, type={Artykuł}, title={Analysis of Distribution of Nitrogen Dioxide Concentration in the Air in the Area of Cracow}, URL={http://rhis.czasopisma.pan.pl/Content/123804/PDF-MASTER/7_AE_VOL_28_1_Kromka_Analiza.pdf}, keywords={nitrogen dioxide, ambient air concentration, monitoring, Cracow agglomeration, statistical methods}, }
