A study of the health aspects of smoking in transport aircraft conducted jointly by the Federal Aviation Administration, Department of Transportation, and the Bureau of Occupational Safety and Health, Environmental Control Administration, Public Health Service, Department of Health, Education, and Welfare, is presented. The purpose of the study was to define the levels of certain combustion by products of tobacco produced by passengers' smoking; to determine passengers' subjective reaction to tobacco smoke; and to obtain passenger opinion on the need for regulatory change regarding the control of smoking in commercial passenger airplanes. The study involved the collection of samples to determine the environmental exposure levels to carbon-monoxide (630080), particulate matter, polynuclear hydrocarbons, ammonia (7664417), and ozone (10028156); and the use of a questionnaire during twenty Military Airlift Command international flights and eight domestic flights. The results of the environmental sampling revealed very low levels of each contaminant measured, much lower than those recommended in occupational and environmental air quality standards. The combustion products were judged not to represent a hazard to the nonsmoking passengers, based on environmental levels and expected dosage response relationships of contaminants. However, an evaluation of the results of the questionnaire indicated that a significant proportion of the nonsmokers (over 60%) were bothered by tobacco smoke and suggested that corrective action be taken such as segregation of the smokers. Furthermore, over 70% of the nonsmokers who had a history of respiratory conditions expressed annoyance by tobacco smoke.
