Respirable dust includes very small particles of dust (diameter less than 10 microns) that when inhaled are able to reach the deepest parts of the lungs. Workers exposed to elevated levels of airborne respirable dust have an increased risk of developing MDLD such as pneumoconiosis, chronic obstructive pulmonary disease (COPD) and lung cancer.
