| Research Abstract |
The historical trends of fly ash particles (spheroidal carbonaceous particles (SCPs) and inorganic ash spheres (IASs)), heavy metals, lead isotope ratios, and polycyclic aromatic hydrocarbons (PAHs) contained in the sediment core samples obtained from the closed waters at East China, islands, urban and suburban regions in Japan were studied. In conclusion, it was found that there were significant differences of historical trends of the concentrations of atmospheric pollutants between urban areas in Japan and isolate islands. The influences of long-range transport of atmospheric pollution at East Asia after 1960s were notably observed at remote islands in Japan Sea and East China Sea.
