Ostrów Wielkopolski's air quality reflects the flat Greater Poland lowland in central Poland, with vehicle traffic on the A2 motorway and surrounding manufacturing and agri-food industry contributing local sources. Winter residential coal and wood burning generates seasonal PM2.5 elevation, while the flat Great Poland plain generally allows reasonable wind dispersal and the broader Silesian regional pollution transport under southerly winds periodically elevates background levels.
