Baton Rouge's air quality reflects its position in the lower Mississippi petrochemical corridor, with one of the US's highest concentrations of oil refineries and chemical plants along the River Road contributing elevated PM2.5, SO₂, and benzene alongside heavy vehicle traffic on I-10 and I-12. The flat Gulf Coast terrain provides reasonable wind dispersal, though the density of industrial sources makes Baton Rouge one of the US's more industrially impacted cities.
