Alba Iulia's air quality reflects the lower Mureș river valley in the Transylvanian plateau, with vehicle traffic on the A1 motorway and surrounding manufacturing and tourism industry contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the Transylvanian plateau ridgelines create topographic variation and winter inversions in the Mureș valley can concentrate heating and vehicle emissions during extended anticyclonic cold periods throughout the year.
