Development of Compact and Low-Cost PM2.5 Mass Concentration Measurement Equipment and Its Application to High-Frequency Mobile Monitoring in a Local Area

Ryozo TAKASU

Abstract


In this study, I developed a new technique that enables the measurement of the mass concentration of airborne PM2.5 by using compact equipment and at lower cost than techniques available to date. By using this technique, I constructed a portable PM2.5 measurement equipment that can measure concentrations with high frequency (every minute). I conducted a measurement experiment by walking along 6 km road with the measurement equipment and found that the spatial distribution of PM2.5 is very uneven in a local area. Therefore, the local area monitoring of PM2.5 concentration by using compact and low-cost equipment will provide better results, thus enabling us to gauge the effect of PM2.5 on human health.
