Valenzuela's air quality reflects Metro Manila's northwestern industrial corridor adjacent to Bulacan Province, with vehicle density and the extraordinary industrial estate, manufacturing, and logistics corridor generating elevated PM2.5 and NOₓ. Consistent Philippine Sea trade winds provide background ventilation, while the extraordinary industrial density maintains moderate to elevated Manila northwestern industrial metropolitan readings throughout most of the year.
