| Research Abstract |
Using the laser-ionization single-particle aerosol mass spectrometer, observation of atmospheric aerosol particles was performed at Fukue, Nagasaki in spring. The instrument obtains chemical compositions of the individual particles with a high time resolution. During the Kosa events, particles containing lead or polycyclic aromatic hydrocarbons were increased. Many of Pb-containing particles observed during the Kosa events also contained other metals attributed to solder and coal combustion, while many of those during non-Kosa periods contained components originating from sea salt. Information about sources or transport and transformation of Asian dust particles or particulate matters including hazardous substances were obtained by the instrument.
