Abstract |
EPA is conducting a research program on halocarbon air pollutants and their possible interaction with stratospheric ozone. Principal compounds under study are fluorocarbon-11, fluorocarbon-12, fluorocarbon-22, carbon tetrachloride, methyl chloroform, perchloroethylene, trichloroethylene, dichloroethane, methylene dichloride, and methyl chloride. Laboratory studies concern the rates of decomposition of these pollutants in the air and the identity and fate of their decomposition products. Field studies involve measuring concentrations of halocarbons and their decomposition products as functions of altitude and distance from sources. Fluorocarbons are discussed in detail, with regard to emission sources, current control technology, and possible chemical substitutes. Problems of emissions control and EPA's regulatory authority are reviewed and the economic impacts of several regulatory options for fluorocarbons are considered. |
