| Outline of Final Research Achievements |
Total four background Asian dust (Kosa) were collected at different desert regions of China. The specific surface area and the total pore volume of the Kosa collected at Huangtu plateau were larger than those at other regions (Taklimakan, Tengger and Horqin). But no significant difference in the average pore size was found among the four Kosas. The compositional differences of analyzed nine water-soluble ions and fifteen elements were observed among the four Kosas. We found that 2 - 4 rings polycyclic aromatic hydrocarbons (PAHs) can be adsorbed by the every Kosa in the conditions of presence or absence of light and reactive gases (NO2/SO2/O3) by using our exposure chamber. We also found that Kosa has catalysis to promote the degeneration reaction of PAHs to their nitro- and/or quinine-derivatives having strong toxicity.
