Outline of Final Research Achievements |
The contribution from transboundary transport from the Asian continent to Japan at the Japanese EANET monitoring sites was evaluated from spatial and temporal distribution of anthropogenic sulfur deposition. In the coast of the Sea of Japan, temporal variations of nss-sulfur isotopic ratio were characterized by seasonal variation with high in winter and low in summer. Similar seasonal variations were also found at the site located in the Pacific coast. The sulfur isotopic ratio was lower with smaller seasonal variation compared with those at the coastal site of the Sea of Japan. It was found that sulfate in precipitation was mainly derived from transboundary transport from the Asian continent. Transboundary transported sulfur deposition in the coastal site of the Sea of Japan (e.g. at Kajikawa, 1.1-20 mg m-2 day-1) was two-three times larger than those in the Pacific coast (e.g. at Tokyo, 0.03-6.7 mg m-2 day-1).
