Ijuí's air quality reflects the Rio Grande do Sul northwestern plateau at 327 metres, with vehicle emissions from the RS-342 and surrounding soybean, wheat, and poultry processing agribusiness contributing local sources. The elevated plateau position aids background dispersal, while dry season burning from surrounding Rio Grande do Sul agricultural land contributes seasonal PM2.5 variation and cold winter temperature inversions in the southern Brazilian highlands add localised wood-burning PM2.5.
