Outline of Final Research Achievements

Exposure to atmospheric aerosols is considered a serious concern for human health. To understand the adverse effects of aerosol particle more accurately, we need to know its physico-chemical properties. In particular, it has been reported that the deposition of particles in the respiratory tract could be enhanced by the surface charge of particulate matter. In this study, we tried to elucide the electrostatic charging state of ambient aerosol particles. In FY2014, we measured the net electrostatic charging state of PM2.5 collected on filter media using two independent methods, a Faraday cage method and a surface potential measurement. In FY2015, we developed a measurement method of the electrostatic charging state of individual ambient aerosol particles using Kelvin probe force microscopy (KPFM). In FY2016, charging state of aerosols was measured using an electrical mobility method with parallel electrode plates.
