| Abstract | To estimate the decomposition rates of chloro compounds in the atmosphere, we carried out laboratory studies on the photolysis rates of the four title compounds, six other chlorohydrocarbons, and 23 other organic compounds under simulated atmospheric conditions. In the presence of nitric oxide, vinylidene chloride, cis- and trans-dichloroethylene, trichloroethylene, and vinyl chloride decomposed at moderate rates (estimated half-lives of 5-12 h under bright sunlight) when compared with a series of standard hydrocarbons. Chlorobenzene, tetrachloroethylene, and 1,1,2-trichloroethane decomposed slowly (estimated half-lives 20-40 h). Methylene chloride and l,l,ltrichloroethane did not decompose (half-lives >250 and >>1700 h respectively). The photodecomposition rates of several chloro compounds were determined in mixtures with other organic compounds and also in the presence of nitrogen dioxide, ozone, chloral, acetaldehyde, chlorine, and phosgene. The presence of hydrocarbons reduced the decomposition rates of several chloroethylenes. |
