Study on the behavior of the secondary atmospheric pollutant and its influence to ecosystem, especially on the acid rain and aerosol
2000 - 2002
The actual state is clarified for the wide range properties and various influences which are essentially possessed by air polluting substances, by the study of chemical and physical change of sulfur dioxide (SO2) and nitrogen oxide (NOx) in air, which are the main atmospheric pollutant. In the study, the formation mechanism of acid rain and acid mist by sulfuric acid (H2SO4) and nitric acid (HNO3), and the influence to forest ecosystem are elucidated. The elucidation is endeavored for the actual state of pollution state by fine particles such as atmospheric floating particular substance (aerosol), especially represented by PM 2.5 problem.
