Pneumoconiosis is a lung condition caused by the inhalation of airborne particles that can damage lung tissue. This is mainly seen with the inhalation of dust from coal (coal workerâs pneumoconiosis), asbestos (asbestosis), silica (silicosis) and beryllium (berylliosis). It is usually due to occupational exposure.
the dust which is stirred and beaten up by digging penetrates into the windpipe and lungs and produces difficulty in breathing. (Agricola, 1556) Crystalline silica (silicon dioxide) has long been recognized as an occupational hazard.
