Observations of Atmospheric Particulate Matters and its Local Environmental Effects in Japan
Authors: Mingyuan Du, Naishen Liang
Abstract: Using optical dust particle counter, simultaneous observation of atmospheric particulate matter (PM) such as PM2.5 and aeolian dust (Kosa) in Tsukuba (farmland environment), Fukuoka (urban environment) and Oku-nikko (forest environment) with different local environments were done. This paper gives a detailed report on the influence of local environment on PM by analyzing the observation data. It has been clarified that the influence of local environment on PM is great due to difference of PM2.5 and Kosa particle concentration in different local environments is very large and the pattern of diurnal variation is different. The annual average PM2.5 concentrations in Tsukuba, Fukuoka and Oku-Nikko were 14.28μg/m3, 24.23μg/m3, and 4.11μg/m3, respectively, and Fukuoka (urban) was the highest. The annual average Kosa particle concentration at the 3 sites was 54.53μg/m3, 43.12μg/m3, 12.33μg/m3, respectively, and Tsukuba (farmland) was the highest indicating that urban environment producing more PM2.5 and farmland environment producing more coarse particles or Kosa.
