Laeken's air quality reflects the Brussels Capital Region's northern industrial and royal park zone, with vehicle traffic on the A12 national road and the surrounding mixed industrial and residential character contributing elevated NOₓ. The flat Belgian plateau provides limited natural dispersal barriers, while prevailing westerlies carry the broader Benelux industrial regional pollution through the Brussels metropolitan corridor and the Brussels-Laeken industrial zone maintains elevated readings above the regional Ardennes rural background throughout the year.
