Most people know that smoking cigarettes can lead to severe lung damage, including chronic obstructive pulmonary disease, or COPD. What they may not realize is that COPD can occur from exposure to hazardous substances at work as well. At the National Institute for Occupational Safety and Health (NIOSH), investigators are studying the causes and how to prevent COPD.
Lung disease from work-related exposure to coal mine dust can damage different parts of the lungs, including the small airways. When these airways, which resemble twigs branching off the trunk of a tree, are damaged, breathing can become significantly difficult.
Asbestos is a long, thin, fibrous mineral made of up of microscopic crystals. There are six different types that are split up into two different groups: serpentine or amphibole.
