Dust consists of particles in the atmosphere that arise from various sources such as soil dust lifted up by wind, volcanic eruptions, and pollution. Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibres, minerals from outdoor soil, human skin cells, and many other materials which may be found in the local environment.
