| Abstract |
The fate of halocarbons released into the atmosphere from anthropogenic sources and their potential impact on the stratospheric ozone layer has been studied. Experimental kinetic data have been obtained for the reaction of OH radicals with CH3Cl, CH2Cl2, CHCl3, C2H5Cl, C2H4Cl2, CH3CCl3, C2Cl4, C2H4Br2, and CO. Best values for the OH + halocarbon rate constants have been assessed and tropospheric lifetime calculated. The kinetics of the homogeneous gas phase hydrolysis of the secondary anthropogenic halocarbon pollutants, CCl3COCl, CCl2HCOCl, CClH2COCl, and COCl2 have been studied. The rate studies show that removal by gas phase hydrolysis would have halflives in excess of 100 years. Some preliminary heterogeneous rain out studies have been made on CCl3COCl, which though not conclusive, suggest that rain out would probably be an effective sink for its removal but that the uncertainties are such that this mechanism requires further study. |
