In this study, the spatial variability of the intake fraction (iF) in Warsaw agglomeration, Poland, is discussed. The iF analysis is based on the earlier air quality modeling results, that include the main pollutants characterizeing an urban atmospheric environment (SO2, NOx, PM10, PM2.5, CO, C6H6, B(a)P, heavy metals). The annual mean concentrations were computed by the CALPUFF modeling system on the basis of the emission and meteorological data from year 2012. The emission field, which is wider than the receptor area, comprises high- (power generation) and low- (industry) point sources, mobile (transport) sources and area (housing) sources. Spatial distributions of iFs atrributed to the individual emission sources in each of the above emission categories are discussed. Moreover, the aggregated iF values are computed for each emission class and the related polluting compounds. The substantial increase of the respective iFs is shown, in both cases, when the emission field is limited to the intra-urban sources only (emission and receptor domains are identical).
