This series of papers is the result of a conference entitled International Conference on Coal Workers' Pneumoconiosis, held by the New York Academy of Sciences on September 13-17, 1971. The papers are divided into 9 sections, the titles and subject matter of which are: I. Coal Mine Dust: analysis; physical and chemical characteristics. II. Mechanisms of Disease: dust retention and clearance; lymphatic drainage; electron microscopic findings; immunological aspects; interaction of mycobacterial infections; role of quartz; antagonistic factors. III. Extent and Distribution of Disease: incidence and mortality trends in the U.S., Poland, Great Britain, South Africa, Yugoslavia, Australia; epidemiological comparison with general populations; influence of lifestyle. IV. Pathological Changes: recognition and pathogenesis of emphysema and fibrocystic disease; bronchial mucus gland status; types of fibrosis; etiological factors and complications. V. Physiological Abnormalities: functional impairment; hemodynamics; lung mechanics; patterns of physiological impairment. VI. Radiological Changes: effect of lung dust content; lung volumes; pathological correlations; disease classification; evidence in compensation claims. VII. Disability and Treatment: pathological, physiological, and radiological correlations; evaluating remaining capacity; the dyspneic miner and benefits; treatment with polyvinyl-pyridine-N- oxide (P2O-4); physiopathological considerations; recognition and management of complications; clinical problems. VIII. Dust Measurement and Control: sampling and evaluation; characterization by computer; recent progress in control of dusts; standards; research perspectives; aqueous suppression and collection; electrostatic precipitation; aqueous foams; the CPM. IX. Problems and Priorities: investigative techniques at the cellular level; historical perspectives. Each section concludes with discussion.
