Abstract
The chemical species in fog sampled at the top of Mt. Akagi and air pollution at the foot of the mountain have been analyzed. SO4 2− and NO3 − concentrations in the fog occurring in Sept. 15 of 1985 were estimated using the combined modified Rutledge's one dimensional stratiform model and chemical reaction mechanism for the production of SO4 2− and NO3 − from SO2 and NOx. Fog pollution was simulated succesfully by the improved stratiform model. Contributions of sulfate in fog were due to particulate SO4 2− and oxidation of dissolved SO2 by H2O2 in water after SO2 gas absorption. Nitrate in fog water is due almost entirely to nucleation in air.Keywords
