Wetzlar's air quality reflects the Lahn river valley in the central Hessian highlands, with vehicle traffic on the A45 and surrounding Leica camera and optics manufacturing and medical technology industry contributing local sources. The Westerwald hills to the east create topographic variation, while the Lahn valley provides ventilation on westerly winds and Wetzlar's precision optics and medical technology character generally maintains moderate emission levels compared to Germany's heavier industrial city corridors throughout the year.
