Sesto San Giovanni's air quality reflects the northern Milan metropolitan area, sharing the Po Valley's notorious enclosed basin with the additional burden of the Breda and Falck steel legacy industrial complex historically making this one of Italy's most industrialised municipalities. Vehicle traffic on the surrounding Milan ring roads and the dense urban industrial character maintain elevated PM2.5 and NOₓ under the Po Valley's persistent winter anticyclones throughout the year.
