Numerical Modeling of VOC Emissions from Ozone Reactions with Human-Worn Clothing in an Aircraft Cabin

Volatile organic compounds (VOCs) are indoor air pollutants with many adverse health effects for humans. Ozone reactions with human surfaces are an important source of VOCs in aircraft cabins. This investigation developed empirical models for computing the emissions of several major VOCs from ozone reactions with human-worn clothing. The empirical models were used to compute the contributions of human surfaces to these VOCs in an aircraft cabin mockup under different environmental conditions after they were compared with the corresponding experimental data. The models can determine ozone-initiated VOC concentrations in the breathing zones of the passengers.
