Hasselt's air quality reflects the Flemish Limburg capital in the Belgian-Dutch-German border region, with vehicle traffic on the E313 and surrounding manufacturing, distribution, and agricultural industry contributing local sources. The flat Campine sandy plain provides reasonable dispersal on most days, while the broader Rhine-Meuse delta regional background and the Albert Canal industrial corridor elevate baseline pollution above typical Belgian provincial capital levels throughout the year.
