| Abstract: | Chemical compositions of suspended particulate matter (SPM) in atmosphere collected at Hachioji and Sakata in Japan from 2002 to 2004 were determined by prompt gamma-ray analysis and instrumental neutron activation analysis. About 40 elemental concentrations in SPM could be determined, and enrichment factors and elemental correlations were examined. Several elements such as Cl, Cr, Ag, Sb, and W were largely different between Hachioji and Sakata, although their sources are not clear at present. |
