Mauá's air quality is significantly influenced by its position in the ABC Paulista industrial corridor south of São Paulo, with chemical, petrochemical, and automotive manufacturing plants generating elevated PM2.5 and NOₓ in one of Brazil's most concentrated industrial zones. The Greater São Paulo basin's poor dispersal characteristics affect the entire ABC region, and Mauá's industrial density keeps readings consistently among the metropolitan area's higher values.
