Narrow Results

In order to shed light on the problem of atmospheric particulate matter (PM) pollution of roadside atmosphere in the Tokyo metropolitan area, we carried out high time-resolution and size-resolved sampling of PM at the Ikegami-Shincho crossing in Kawasaki City, Kanagawa Prefecture, Japan. Elemental and ionic composition analysis of those samples was then conducted. The research results are important for the physicochemical characterization of nano- to micrometer-size particles in roadside atmosphere, enabling detailed analysis of the various roadside emission sources and atmospheric processes.
