National Heart and Lung Institute, The Dust Inhalation Diseases (1973)

An 18-page public booklet on the pneumoconioses, prepared by the Office of Information for the Division of Lung Diseases of the National Heart and Lung Institute and printed by the Government Printing Office in 1973. It describes silicosis, asbestosis, coal workers' pneumoconiosis and rarer dust diseases, their symptoms, diagnosis and prevention. It says asbestosis "now ranks as our leading dust inhalation hazard," that asbestos is "believed to be a leading factor in the death of over 2,000 people in the United States each year," and that asbestos workers who smoke have a lung cancer rate "eight times higher than smokers in the general population."
