| Research Abstract |
In order to investigate chemical components of PM1, airborne particles were collected by use of Andersen samplers at four sites : Shinjuku, Kazo, the top of Mt. Fuji and Shanghai. Water soluble inorganic ions and metal elements in PM1 samples were measured.
New classification method of particulate matters based on the difference of magnetic properties was also developed. As a result of applying that for PM1 samples, we found that the ratios of magnetic fraction to total concentration of some elements were different between Kazo and Shanghai.
