Tournai's air quality reflects the Scheldt river valley in the Belgian-French border region, with vehicle traffic on the E42 motorway and the surrounding cement and manufacturing industry — Tournai being Belgium's major cement production city — generating elevated cement dust PM10 alongside primary vehicle and industrial NOₓ sources. The flat Walloon plain provides reasonable dispersal, while the cement industry's distinctive PM10 profile makes Tournai one of Belgium's more industrially specific urban environments.
