Itaperuna's air quality reflects the northwestern Rio de Janeiro state, with vehicle emissions from the BR-356 and surrounding cattle ranching, dairy, and light manufacturing contributing local sources in this major Noroeste Fluminense commercial city. The surrounding Mantiqueira range foothills create topographic variation, while Atlantic sea breezes from the nearby Espírito Santo coast provide periodic ventilation relief and dry season burning contributes seasonal PM2.5 variation.
