Abstract

We made a close analysis of individual atmospheric particles sampled near to road traffic and a railroad with a personal air sampler using a field emission type scanning electron microscope. From the results of an electron microprobe analysis, the particles were classified into five types. Some particles had minute attachments on them. From comparisons of the X-ray spectra of the carrier particles and their attachments, we concluded that they were composite particles of a Fe carrier particle of railroad origin and the attached diesel exhaust particles.<br>
