Debrecen's air quality reflects its position on the flat Great Hungarian Plain, with vehicle traffic on the M35 motorway and the surrounding agricultural and pharmaceutical manufacturing industry contributing local sources. The flat Alföld terrain generally allows reasonable wind dispersal on most days, while winter residential heating and temperature inversions on the open Hungarian plain contribute seasonal PM2.5 elevation in this major eastern Hungarian university and medical city.
