Why are airplanes a concern?
Airplanes make it possible for thousands of people to travel short and long distances every day, within and outside the United States. However, airplanes emit several hazardous air pollutants, and aviation industry workers can be exposed to several toxic chemicals.
Airplanes emit air pollutants that include carbon monoxide, nitrogen oxides,sulfur oxides, methane, particulate matter, volatile organic compounds (such as benzene and toluene), and carbon dioxide, a greenhouse gas that contributes to global warming. Chemicals used to de-ice airplanes in the winter include propylene glycol and ethylene glycol which may run into and contaminate local waterways.
Aviation employees who work in airplane ground service and maintenance can be exposed to gasoline, jet fuel, solvents, glues, degreasers, and coatings which may contain toxic chemicals.
While the air quality of an airplane cabin is similar to other indoor environments, there are also differences. Passengers on a plane are in a more densely populated area than usual. Those flying on an airplane are exposed to low humidity and reduced air pressure in the cabin, as well as potential exposure to air contaminants, including ozone and allergens.
Flight crews and passengers may be exposed to pesticides if pesticide spraying is required in the airplane before it takes off. International flights are more likely to require pesticide spraying to prevent spreading plant diseases and pests from one region to another. They may also be exposed to water pollutants, if the drinking water aboard the airplanes fails to meet federal standards, and small amounts of cosmic radiation.
