The volatile organic compounds emitted in indoor environments may undergo gas-phase or surface-phase chemistry by reacting with species such as ozone, hydroxyl radical or nitrate radicals. This chemistry can result in the formation of oxygenated organic compounds such as aldehydes, ketones and dicarbonyls that could lead to negative health effects. In order to more accurately assess worker exposure, investigations into the detailed gas-phase chemistry of these emitted volatile organic compounds are needed. For example, several high volume chemicals such as alpha-terpineol, dihydromyrcenol and 3,5-dimethyl-1-hexyn-3-ol used in wood treatment products and surface cleaning products do not have well understood indoor environment reaction mechanisms. Using the relative rate technique to measure reaction rate constants and chemical derivatization techniques to identify reaction products, a more accurate assessment of these chemicals' impact on exposure is possible. Descriptions of the kinetic measurement, reaction product identification techniques and experimental results will be presented.
