The pneumoconioses are by and large industrial diseases, although casual contact may be important on occasion, particularly with asbestos. The effect of dust on the lung ranges from only radiographic changes to severe functional impairment. Destruction and fibrosis of lung parenchyma may be the end result in severe disease. Great improvement has been made in recent years in the control of dust in the numerous situations where it may cause disease. We are still faced with evaluating existing standards of particle concentration in air breathed by workers and establishing safe limits and better control of the particles placed into the general environment. Undoubtedly, there are other particulates which potentially can cause lung disease of which we are not aware. Of even more concern is the realization that a latent period of 20 years or so may be necessary for physicians to become aware of the pathologic process. Every physician who sees patients with pulmonary problems must inquire regarding a history of dust exposure and be prepared to interpret that history.

Review
The stringent industrial hygiene regulations that have been introduced in North America, Europe, and Australasia have led to a decline in the incidence and prevalence of silicosis, coal workers' pneumoconiosis, and asbestosis. Although new cases of asbestosis are not occurring, an appreciable number of mesotheliomata are still being diagnosed, and there has yet been little, if any, decline in the latter tumor. These new cases are nearly entirely due to exposure to amphiboles in the 1940s and 1950s. It is expected that by about the year 2000 the incidence of mesothelioma will begin to decrease in the United States and Canada. Meanwhile there is an undue preoccupation with more and more sensitive methods of detecting asbestosis, silicosis, and coal workers' pneumoconiosis, eg, magnetic resonance imaging, bronchoalveolar lavage, and so forth. Much effort is being made in trying to detect disease in groups of workers with extremely low exposures and no symptoms. Smaller and smaller effects are being detected, with the ultimate aim appearing to be detecting nothing at all. Efforts should be made at surveying other populations exposed to agents that have recently been introduced and that could conceivably have long-term effects.

Workers exposed to harmful dusts such as coal often are screened for possible pneumoconiosis. A classification devised by the International Labor Office (ILO) is used for film interpretation. Film interpretation is time consuming and requires the comparison of the subject's radiograph with as many as 22 standard films and the completion of a nonintuitive form. A computer program has been written to aid in interpretation of films. This program, written in SuperCard, uses hypermedia concepts to link textual, diagrammatic, and digital images. The program includes digitized ILO radiographs, guidelines, references, and other textual and radiographic material. The program is easy to use and reduces the time required to interpret films. The concepts of how the program is constructed are emphasized so that others may devise similar program aids.

Review
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.
