Maricá's air quality benefits from its Rio de Janeiro state coastal position on the Maricá Lagoon complex, with consistent Atlantic sea breezes providing reliable maritime ventilation along this rapidly urbanising coastal municipality. Vehicle emissions from the RJ-106 and growing residential and oil industry support development are the primary local sources, while the Petrobras pre-salt oil industry expansion in the region adds emerging industrial emissions alongside the primary coastal tourism character.
