Abstract
Ambient levels of atmospheric Freons, halogenated hydrocarbons, and SF6 were measured at various locations in the U.S.A. Compounds such as CCl3F, CCl2F2, CH3-CCl3, and CCl4 were ubiquitious and generally measured at sub ppb levels. Tropospherically reactive compounds such as C2Cl4 and CHClCCl2 were frequently measured; other compounds were measured where a reasonable source was known. A novel pulsed flow coulometry gas chromatographic analysis along with other requisite analytical and calibration procedures were developed and used. Laboratory irradiation simulations established the tropospheric stability of CCl3F, CCl2F2, CH3CCl3, CCl4, CCl2FCClF2, the reactivity of the chlorinated ethylenes, and the stratospheric reactivity of CCl3F, CCl4, and CCl2F2. Adventitious labelling of air masses with halogenated compounds was used to demonstrate urban ozone transport to rural areas.
