Bydgoszcz's air quality faces winter challenges from residential coal and wood burning generating elevated PM2.5 alongside vehicle traffic on the surrounding expressway network in this major Polish industrial and logistics city. The flat Kujawy-Pomerania plain provides reasonable wind dispersal on most days, while the Brda river corridor provides a natural ventilation pathway through the city and the broader Vistula river basin influences regional air quality transport.
