It is generally believed that organic matters in SPM are mainly composed of diesel exhaust particulate and soot from residential chimneys or industrial smokestacks. To determine the contribution ratios of several organic substances to SPM, we characterized SPM, diesel exhaust particulate (DEP), powdered summer radial tire, and bitumen, using high performance liquid chromatography, field desorption mass spectrometry and linear theory.Journal Articleapplication/pdfhttp://hdl.handle.net/2115/42824https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/42824/1/moriyoshi_SAE2002-01-0653.pdf0148-7191SAE technical paper series2002-01-0653162002eng"SAE Paper 2002-01-0653 (c) 2002 SAE International.
