Abstract: Air pollution, in terms of particulate matter (PM 10 , PM 2.5 , PM 1.0 ) and gaseous pollutants (H 2 S and VOC), has serious health effects, particularly in cities. The evaluation of outdoor air quality was carried out in the vicinity of a small paintshop operating in the city of Łódź, Poland. The concentrations of pollutants in the vertical profiles (up to 47 m a.g.l.) of ambient air were measured using a mobile platform (unmanned aerial vehicle with measuring equipment) during three measurement campaigns in September 2021. The vertical structure of the pollutant concentrations indicated the occurrence of different types of layers with an almost constant concentration near the land surface, a strong decrease (up to ca. 10–15 m a.g.l.), and significant fluctuations in concentrations to higher levels (above 25 m a.g.l.). Particulate matter concentrations (PM 10 , PM 2.5 , PM 1.0 ) did not exceed 39 µg m −3 , with stable levels on the surface. The maximum value of particulate matter concentrations (up to 38.5 µg m −3 ) in the vertical profiles was recorded at ca. 35–40 m a.g.l. The average concentrations of H 2 S and VOC varied between 0.07 and 0.12 ppm and 0.01 and 0.27 ppm, respectively. The highest H 2 S concentrations were observed at ca. 18–23 m a.g.l., reaching 0.14 ppm. A rapid increase in VOC concentrations, reaching 0.29 ppm, was measured in vertical profiles from 20 m a.g.l. and up to about 40 m a.g.l. In situ measurement approaches were combined with interpolation methods in the GIS system to investigate the spatial variability of pollution levels from a specified source in the urban atmosphere. Based on the survey results, the kriging interpolation method was well suited for generating spatially distributed pollution maps for individual measurement campaigns.
