Forest's air quality reflects the Brussels Capital Region's southern suburban residential corridor, with vehicle traffic on the R0 ring road and the surrounding residential and commercial character contributing elevated NOₓ. The flat Belgian plateau provides limited natural dispersal, while prevailing westerlies carry the broader Brussels metropolitan and Benelux industrial regional pollution through the Forest-Uccle corridor and the residential suburban character maintains moderate to elevated inner Brussels metropolitan readings throughout the year.
