| Abstract |
The U.S. Department of Transportation (DOT) sponsored a study to quantify pollutant levels in airliner cabins and to assess the associated health risks for cabin crew members and passengers. Study measurements focused on environmental tobacco smoke but also included other contaminants and environmental parameters. The article reports on the study methods, results, and implications as they relate to carbon dioxide (CO2). Based on monitoring near the middle of the airliner cabin, CO2 concentrations averaged 1,615ppm across all 92 study flights. Average CO2 levels were somewhat lower on smoking (1,568ppm) than non-smoking (1,756ppm) flights. Measured CO2 concentrations exceeded the 1,000ppm level of ASHRAE Standard 62-1989 on 87% of the flights. Even for flights with the highest ventilation rates (exceeding 35 cfm/passenger), the average CO2 levels were about 1,250ppm. The relationship of CO2 to selected factors (type of aircraft, air recirculation, load factor, fresh air rate) is presented. |
