| Outline of Final Research Achievements |
Coal combustion exhausts transported from northeast Asia region were found in rime ice and snow collected on the summit of mountain (1400 m alt.) in Shikoku Island. The coal combustion with no exhaust purification specifically emits 1) aerosol particulates including cadmium and lead, 2) gaseous pollutants such as SO2 converting to sulfate, 3) products of incomplete combustion, and 4) inorganic small spherical particles (ISPs) from power plants. It was found in the rime and snow that organic sulfur species indicates to
a proof of the coal exhaust. A methodology for determination of generating area in northeast Asia was proposed by the chemical composition of the ISPs, heavy metals and sulfate ion concentration based on meteorological information. It can be concluded that the generating areas of air pollution were the region of Huabei of China and the south area of northeast China.
