[in Ukrainian with English abstract:] The results of lichen indication studies of the atmospheric air in Fastiv (Kiev Region) are presented. In total, 68 species of lichens have been identified, of which 19 species are indicative. Distribution maps of the indicative species of lichens were produced. Based on the data obtained as a result of calculation of atmospheric purity index (IAP) by Le Blanc & De Sloover, a distribution map of lichen indication zones within the town was prepared. The location of various zones is analyzed. In general, the atmospheric air in the urban settlement of Fastiv is moderately polluted. The area near railway station and the eastern part of Fastiv are more polluted than the rest of its territory. Species with high sensitivity to air pollution were found mostly in the western part of Fastiv.
