Zgierz's air quality reflects the flat Łódź industrial metropolitan area in central Poland, with vehicle traffic on the S14 expressway and the surrounding textile and manufacturing legacy industry contributing local sources. Winter residential coal and wood burning generates elevated PM2.5, while the flat central Polish plain provides reasonable dispersal and the Łódź metropolitan area's regional pollution background consistently influences the air quality environment throughout the year.
