Specializes in Pulmonology

Silicosis develops: from chronic and repeated exposure, usually needing years. Biologically, the lungs are saturated with silica dust and the macrophages are overwhelmed in their role to clear the silica. Thus, toxicity and damage result. Respirators are required by OSHA.
