摘要：

Condensation nuclei (CN) separated during winter 1982-1983 in Colorado consisted mostly of sulfates and chlorides, with nitrates practically absent. Nitrates were present in all precipitation (rain and snow). CN condensate collected in the presence of haze contained the largest amounts of sulfate and nitrate recorded. Nitrates were present in low concentrations in CN separated in the presence of fogs. The pH of the separated CN varied from 5. 2 to 6. 6; the pH of rain samples was between 4. 6 and 5. 3, and that of the snow samples was between 3. 9 and 4. 9. Analysis of single aerosol particles collected since 1979 showed the predominant anion to be sulfate. Nitrate ion-bearing aerosol particles were not detected on some days. Refs.
