Organic Emissions from Consumer Products and Building Materials to the Indoor Environment

Abstract

Organic vapors are emitted to the indoor air from a variety of consumer products and building materials. The U.S. EPA Is evaluating the emission characteristics from such sources using small environmental test chambers. Emission rate data are presented, and the effect of temperature and air exchange rate are discussed. Models are used to account for the Impact of chamber concentration and “wall effects” on emission rates. Indoor concentrations of specific organlcs emitted from a silicone caulk are estimated from the chamber test data.
