Milan's air quality is among the most challenging in northern Europe, with the Po Valley's notorious flat basin surrounded by the Alps and Apennines trapping vehicle and industrial emissions under persistent winter anticyclones. This produces some of the EU's highest NO₂ and PM2.5 concentrations, while summer Po Valley ozone is a major warm-season health concern.
