ATLANTA, GA — According to researchers at the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), concentrations of air contaminants measured in a study of commercial aircraft were found to be generally lower than those in residential or commercial buildings.
According to ASHRAE, “Certain volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs) are suspected of entering aircraft through bleed air systems that supply outdoor air to the cabin.”
