The most prevalent pneumoconioses are silicosis, asbestosis and coal worker's pneumoconiosis. Other pneumoconioses that have distinct clinical, functional and structural repercussions are caused by inhalation of metal powder in fumes from metals or organic salts. The distinction in terms of the chemical form of the inhaled compound is related to the tissue reaction and to the prognosis. Simple pneumoconiosis, siderosis, berylliosis and phosphate rock-related pneumoconiosis, as well as chronic obstructive pulmonary disease caused by exposure to heavy metals, are succinctly discussed. As an instrument of etiologic investigation of these pneumoconioses, the taking of occupational histories is essential.
