MANHATTAN, Kan. -- In a tightly enclosed area, such as an airplane, the quality and safety of the air is of utmost importance. In addition to concerns about general air quality, added recent concerns have included accidental contamination of aircraft cabins -- such as with pandemic flu -- and deliberate contamination with biological agents -- such as anthrax -- as part of a terrorist attack.
Kansas State University is part of a federally established center to examine air quality in aircraft cabins and assess chemical and biological threats in airliners. The Air Transportation Center of Excellence for Airline Cabin Environment Research, established by the U.S. Department of Transportation's Federal Aviation Administration, also has as partners Auburn University, Purdue University, Harvard University, Boise State University, the University of California at Berkeley and the University of Medicine and Dentistry of New Jersey.
Byron Jones, director of K-State's Engineering Experiment Station and professor of mechanical and nuclear engineering, heads up K-State's efforts for the center. He said the center's projects are all collaborations among the eight institutions. Jones said the center's mission is to address air issues, ensuring air travel is healthy, and at the same time, keeping it economical. In addition, the center is examining safety during deliberate attempts to contaminate the air in-flight.
"Although the science is similar with both of these missions, the application is different," Jones said. "Our job is to protect the environment as best we can -- detect, protect and clean up after it. Whether an air incident is deliberate or accidental, the idea is the same and both are important."
The center was established in 2004 and since that time, the institutions have begun various projects to understand and mitigate environmental health issues on airplanes, including looking into abnormal incidents where a plane's air supply has been contaminated with engine oil or hydraulic fluid, for example; how cabin pressure affects passengers, especially those with cardiopulmonary problems, as well as flight attendants and pilots who work in the environment daily; seeing how elevated ozone levels at higher altitudes affect the cabin environment; creating a database on the in-flight air environment; looking at the basic science of how contaminants travel about the cabin; what sensors will best detect certain things in cabin air; and the best strategies to decontaminate an airplane.
"How do you deal with an intentional attack if the attack is invisible -- that is, what if somebody is releasing something into the cabin environment that cannot be seen -- how can we even detect it? This is one of the things we're looking at," Jones said.
"Air travel is the mass transportation medium for long distances in North America," Jones said. "And yet it's conducted in an 'alien' environment -- the outside environment at typical flight altitudes is very hostile to human habitation. While in an aircraft, we depend on the aircraft and its environmental control system for safety."
"If you have an incident on an airline, it will have a huge negative impact on the entire industry, and the particular airline specifically," he said. "If the airline has a secure environment and knows how to deal with these factors if they arise, it will have less of an impact."
Researchers have begun various projects to understand and mitigate environmental health issues on airplanes.
While the airplane research covers accidental contamination and the natural spread of viruses such as flu or chickenpox, the deliberate spread of toxins is a key concern.
