Bonn's air quality reflects its position in the Rhine valley south of Cologne, with vehicle traffic on the A565 and the B9 Rhine corridor and the dense commuter flow to the federal government offices contributing elevated NOₓ. The Rhine provides the primary natural ventilation corridor, while the Siebengebirge hills to the southeast and the Eifel highlands to the west create modest topographic variation in pollution exposure across this former German capital.
