Bratislava's air quality faces winter challenges, with residential heating and vehicle traffic on the D1 and D2 motorway interchange generating elevated PM2.5 and NO₂. The Danube river corridor provides ventilation on westerly winds, while the Little Carpathian hills to the north and the Pannonian plain to the south create topographic variation in pollution exposure across this compact Central European capital.
