Description:
The paper describes results of tests, conducted in the U.S. Environmental Protection Agency (EPA) large chamber facility, that investigated emissions of volatile organic compounds (VOCS) from one electrical plug-in type air freshener with pine-scented refills. VOCs were measured in the presence and absence of ozone. Chamber conditions such as temperature, relative humidity, pressure, and air exchange rate and environmental conditions such as the concentrations of ozone and oxides of nitrogen were controlled and/or monitored. SCIENTIST software was used to obtain parameters of air freshener source emission models, and the RISK simulation program was applied to predict the VOC concentrations in the EPA Indoor Air Quality (IAQ) Research House. The results provide information on air freshener emissions and could be used for more detailed simulations and predictions incorporating ozone and VOC reactions. Models used in the simulation of this study could serve as a reasonable starting point for development of a general IAQ model.
