Sulfite mills emit sulfur dioxide (SO2) which has a strong, choking odor. Wastewater treatment plants can have a rotten garbage odor, and landfills may have an odor from decaying organic matter. Odors from these sources will vary depending on a person's smell sensitivity, changes in wind direction, temperature, and mill processing techniques.
