Constanța's air quality reflects its position as Romania's main Black Sea port, with shipping, refinery, and industrial emissions from the MIDIA petrochemical complex and the Constanța South industrial port contributing elevated SO₂ and PM2.5. Black Sea easterly breezes provide maritime ventilation on most days, while the flat Dobrogea plateau generally allows reasonable dispersal and winter residential wood and coal burning contributes seasonal PM2.5 elevation across this coastal Romanian city.
