Relevant procedure was adopted to find out if the concentration values in these two seasons differed in kind. The concentration seasonal difference was not found in case of cadmium but it was found for lead. It was proved in further part of the paper that the analysed mean 24-hour Pb concentrations for heating season could be presented as a sum of the mean annual background concentration and the concentration values resulted from Pb emission from sources active only in the heating season. In the area where the measurements were carried out residential furnaces were this kind of sources. The cumulative distribution function of the mean 24-hour lead concentration resulted from Pb emissions in the heating season was determined using two-layer neural network. It was found according to this approach that Pb concentration as the result of Pb emissions from residential furnaces, for 145 days, i.e. 80% of the heating season period, were at least two-fold lower than the lead concentration values as the result of Pb emission from the all year active sources. Only for 14 days emission sources active in the heating season produced Pb concentrations higher than Pb mean annual background concentration.}, type={Artykuł}, title={Effect of Lead and Cadmium Emission from Residential Furnaces on concentration of these Pollutants in the Air}, URL={http://www.journals.pan.pl/Content/123992/PDF-MASTER/7_AE_VOL_27_3_2001_Klis_Wplyw.pdf}, keywords={lead, cadmium, concentration, residential furnaces, heavy metals, neural network}, }
