Cotton dust is often present in the air during cotton handling and processing. Cotton dust may contain many substances including ground-up plant matter, fiber, bacteria, fungi, soil, pesticides, non-cotton matter, and other contaminants that may have accumulated during growing, harvesting, and subsequent processing or storage periods.
