São Paulo's Guarulhos corridor air quality reflects the greater metropolitan industrial and logistics zone surrounding Guarulhos International Airport, with the airport's aviation operations and the surrounding manufacturing and freight logistics generating elevated NOₓ and PM2.5. The São Paulo basin's poor dispersal characteristics affect the entire northeastern corridor, while the industrial and aviation concentration makes this one of the greater São Paulo metropolitan area's more challenging air quality environments throughout the year.
