Esteio's air quality reflects the greater Porto Alegre metropolitan area's northern corridor in Rio Grande do Sul, with vehicle emissions from the BR-116 and the surrounding mixed industrial and residential character of this major metropolitan satellite contributing local sources. The flat Guaíba river plain provides limited dispersal barriers, while the industrial character of the northern Porto Alegre corridor generates moderate persistent emission levels throughout the year.
