Lifetimes and fates of toxic chemicals in California's atmosphere. Final report, 29 January 1986-31 October 1987
The kinetics and/or the products of the gas-phase reactions of Hydroxyl (OH) radicals, ozone (O/sub 3/), and nitrate (NO/sub 3/) radicals with ethylene oxide, vinyl chloride, 1,1-dichloroethene, cis- and trans-1,2-dichloroethene, trichloroethene, tetrachloroethene, acrolein, allyl chloride, benzyl chloride, o-,m- and p-cresol, naphthalene, 1,4-benzodioxan and 2,3-dihydrobenzofuran were experimentally investigated. These kinetic data were used to calculate corresponding atmospheric lifetimes for each compound, for the three possible reaction pathways. None of the compounds investigated react sufficiently fast with O/sub 3/ under atmospheric conditions for the process to represent a significant atmospheric removal pathway. Where feasible, product studies were conducted, principally using in situ Fourier transform infrared spectroscopy and gas chromatography, to determine the atmospheric reaction products produced from the parent compounds investigated. The OH radical rate constant data obtained in the program were combined with available literature data in order to further develop appropriate structure-reactivity relationships.
