Brief Summary:
The overall objective of the Center was to develop a scientific data base for the control and prevention of acute and chronic lung injury caused by the inhalation of a variety of agents in the workplace and in the environment. There were two epidemiologic studies.
Respiratory Effects of Exposures to Irritant Gases: To collect longitudinal lung function and symptom data in chemical manufacturing workers who were exposed to chemical irritants such as ammonia, chlorine, phosgene, isocyanates, sulphur dioxide, nitrous oxide, formaldehyde, organic acids, hydrochloric acid fluorides, other aldehydes, and acid anhydrides.
Workers in the Cotton Textile Industry: To detect and quantitate the risk for the development of chronic obstructive airways disease which occurred in workers exposed to cotton dust in textile manufacturing.
