Niš's air quality faces significant winter challenges as Serbia's third-largest city, with residential coal and wood burning generating elevated PM2.5 alongside vehicle traffic on the E75 motorway corridor. The Nišava river valley's partial topographic enclosure between the surrounding Balkan mountain ranges creates concentration of heating and vehicle emissions under frequent winter temperature inversions, while summer conditions are considerably better with reasonable wind dispersal across the flat Nišava plain below the Suva Planina massif.
