Erechim's air quality reflects the Rio Grande do Sul northern highlands plateau at 760 metres, with vehicle emissions from the BR-153 and surrounding soybean, wheat, and poultry processing agribusiness contributing local sources. The elevated plateau position aids background dispersal, while cold winter temperature inversions in the southern Brazilian highlands and dry season agricultural burning contribute seasonal PM2.5 variation and wood burning for residential heating adds a winter local source.
