What are the health risks of breathing industrial dust, mist and fumes?

Breathing industrial dust may contribute to a wide range of occupational health risks, depending on the type, size and concentration of particles. Some dusts are considered nuisance dusts and may cause irritation, while others—such as silica, metal particulates, pharmaceutical powders or combustible dusts—may contribute to more serious respiratory conditions, reduced lung function or long-term disease risks.
