Popești-Leordeni's air quality reflects the greater Bucharest metropolitan area's southern suburban ring, with vehicle traffic on the A1 motorway and the surrounding mixed industrial and residential character contributing elevated NOₓ. The flat Wallachian plain provides reasonable dispersal on most days, while winter residential wood and coal burning and the Bucharest metropolitan area's winter temperature inversions concentrate heating and vehicle emissions across the southern suburban corridor during extended anticyclonic cold periods throughout the year.
