Paulínia's air quality faces significant industrial challenges as the location of the Replan petroleum refinery, Brazil's largest oil refinery, generating elevated SO₂, benzene, and industrial PM2.5 alongside the surrounding Polo Industrial de Paulínia chemical complex. The Campinas basin's topographic setting affects dispersal, while the refinery's extraordinary scale makes Paulínia one of São Paulo state's most distinctively industrial-defined urban air quality environments.
