Abstract |
In previous publications (McMurry and Wilson, 1982; McMurry et al., 1981), techniques for determining the relative contributions of gas phase and liquid phase reactions to secondary ambient aerosol formation have been described. In this paper these methods are applied to more recent data acquired during the 1980 Environmental Protection Agency PEPE-NEROS study near Columbus, Ohio. It is shown that liquid phase reactions tend to be the most important mechanism of sulfate aerosol formation for relative humidities greater than 75%, while gas phase reactions are predominant at lower humidities. |
