Gravataí's air quality reflects its position in the greater Porto Alegre metropolitan area's northern industrial corridor in Rio Grande do Sul, with General Motors' Gravataí automotive manufacturing plant and the surrounding industrial zone contributing elevated NOₓ and PM2.5 alongside heavy traffic on the BR-290 freeway. The flat Guaíba river basin plain provides limited dispersal barriers, and Gravataí's industrial automotive character makes it one of the greater Porto Alegre metropolitan area's more polluted municipalities.
