Târgu-Mureș' air quality reflects the Mureș river valley in the Transylvanian plateau, with the Azomureș fertiliser plant and surrounding chemical manufacturing contributing elevated industrial PM2.5 alongside winter residential wood and coal burning. The Mureș valley's topographic enclosure creates concentration under winter inversions, while surrounding Transylvanian highlands provide better ventilation on windy days.
