Outline of Final Research Achievements

We have developed the analytical system for the monitoring of atmospheric water-soluble acidic gases and anions in particulate matter at the summit of Mt. Fuji. The system provides automatically one acidic gas and one particulate matter data in an hour. We applied the system to the continuous measurement of atmospheric HNO3, SO2, NO3-, and SO42- at the summit of Mt. Fuji, Japan. Backward trajectory analysis suggested that high concentration of SO42- emitted from the Asian Continent was transported to the sampling site.
