Ribeirão Pires' air quality reflects the southeastern Greater São Paulo metropolitan ring adjacent to the ABC Paulista industrial corridor, with vehicle emissions from the Anchieta highway and surrounding mixed industrial character contributing elevated PM2.5. The Serra do Mar escarpment creates topographic concentration, while the São Paulo basin's poor dispersal characteristics affect the entire southeastern corridor throughout the year.
