Metz' air quality reflects the Moselle river valley at the Franco-German-Luxembourg border, with vehicle traffic on the A31 and surrounding logistics corridor contributing local sources. The Moselle valley provides ventilation on westerly winds, while cross-border emissions from Luxembourg and the Saarland industrial corridors elevate background levels above typical French regional city averages.
