| Outline of Final Research Achievements |
This study aimed to understand spaciotemporal distribution of transboundary air pollution over Japanese Islands with combination methods of 210Pb and 137Cs sedimentation rate determinations, Pb concentration and Pb isotopic analyses using previously archived lake sediment cores from 6 lakes. We have successfully revealed the properties of spatial distribution of the Pb pollution over north-south trending Japanese Islands and historical changes of pollution intensities with their source rejoins back to 100 years ago. Proposed methodology could most efficiently be applied in northern Japanese lakes such as Mikazuki Lake, Chokai Lake, and Mikuriga Lake, and these three lakes are proposed to be preserved for further surveys to monitor ongoing transboundary pollutions for multiple chemical factors. To further improve understanding on comprehensive transboundary air pollution high-resolution chemical and isotopic mapping is needed in future work.
