Airborne particulate matter was collected at 4 types of sampling site; industrial, residential, seashore and suburban areas, and Te and Se concentrations in the samples were analyzed by graphite furnace atomic absorption spectrometry. Higher concentrations of Te and Se were observed when wind directions were from industrial and particular emission sources. At Hiyoshi, near Keihin industrial zone, rather low concentrations of Te were observed in winter season predominated by northern wind, while those of Se did not show clear variation on yearly basis. Te and Se were found about 78% and 71%, respectively, in fine particles smaller than 2μm in aerodynamic diameter in size fractionated sampling.
