Arezzo's air quality reflects the Arno valley's topographic enclosure in Tuscany, with vehicle traffic on the A1 motorway and surrounding gold jewellery, fashion, and manufacturing industry contributing local sources. The Apennine ridgelines create topographic enclosure that concentrates emissions under calm winter conditions, while the Arno valley provides the primary ventilation corridor and summer Etesian winds provide periodic relief.
