Outline of Final Research Achievements

(1)Magnetic separation technique with two-step, using neodymium magnets of 0.4T and 1.2T was developed in order to classify elements in fine particulate matter.
(2)Simultanious sampling campaign in China and Japan was carried out in summer and winter in order to obtain PM2.5 and PM1 samples and characterize its chemical components in recent years.
(3)Ratios of Magnetic fraction(MF) to total mass of samples at Beijing and Kazo were in the range of 0.01-0.02. EDX spectrum and individual particle analysis of MF showed oxides of Fe and Cu. The ratio of MF to total mass of fly ashes collected in China was more than 0.7. The ratio As/V, as an indicator of coal combustion increased when air mass came from China in summer.
