Busto Arsizio's air quality faces the Po Valley's enclosed flat basin in the Varese province, with vehicle traffic on the A8 motorway and surrounding textile and manufacturing industry contributing elevated PM2.5 alongside the persistent winter anticyclone trapping. The flat Lombardy plain concentrates all emission sources under winter inversions, while the Malpensa Airport's aviation operations nearby contribute additional NOₓ and ultrafine particles to the local air quality profile.
