APPLICATION OF POLLUTION PREVENTION TECHNIQUES TO REDUCE INDOOR AIR EMISSONS FROM AEROSOL CONSUMER PRODUCTS
Bayer, C. W., R. A. Browner, S. Ho, L. L. Christianson, L. Y. Zhao, P. Heiselberg, M. Tumbleson, AND M. M. Cui. APPLICATION OF POLLUTION PREVENTION TECHNIQUES TO REDUCE INDOOR AIR EMISSONS FROM AEROSOL CONSUMER PRODUCTS. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-01/039 (NTIS PB2001-107254), 2001.
The report gives results of a research project to develop tools and methodologies to measure aerosol chemical and particle dispersion through space. These tools can be used to devise pollution prevention strategies that could reduce occupant chemical exposures and guide manufacturers in formulating more efficacious products. The researchers built an Aerosol Mass Spectral Interface (AMSI), which is interfaced with a mass spectrometer (MS), that chemically characterizes aerosol consumer products as they move through space. They also developed techniques for measuring aerosol movement indoors by tracking particle size changes via particle velocity measurements using particle image velocimetry (PIV). The AMSI was designed, constructed, and optimized to transfer a focused beam of aerosol particles into a MS for chemical analysis. Experiments showed that the AMSI can quantitatively detect compositional changes as the aerosol moves through space. These data provide important information for formulating aerosol consumer products for pollution prevention strategies. The PIV system demonstrated a correlation between the material properties of the aerosol components and the spray patterns. The model can be used to help develop pollution prevention strategies.
