Analysis of Contribution to SPM by Organic Matters Using High-Performance Liquid Chromatography (HPLC) 2002-01-0653

Most countries consider it is harmful for humans to inhale SPM of fine organic particles and elemental carbon less than 2.5 μ in diameter1,2). It is generally believed that organic matters in SPM are mainly composed of diesel exhaust particulate and soot from residential chimneys or industrial smokestacks3,4). 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.
