|Molds (fungi) and their spores emit both solids and gases into the environment. Molds emit a wide range of allergens and large toxic molecules (mycotoxins) in solid forms, often on very small particles which travel freely in the air. Molds also emit a wide range of gases such as acetone, ethanol, and hexane.|

Heavy mold growth indoors or on food often gives off strong, “musty”, and usually unpleasant odors.
