| Abstract | An online particulate monitoring system for measuring the mass and number concentrations and size distributions ofambient particulate matter was developed and field tested in this study. The developed monitoring system consisted of electrostatic PM mass monitor (EPMM), NanoScan-SMPS, data acquisition and wireless communication systems, and monitoring station structure with an air conditioning system. In this study, the monitoring station was placed and field evaluated in Chiang MaiUniversity Mae-Hia, Mae-Hia, Mueang Chiang Mai District, in Chiang Mai Province, Thailand. The field study results showedthat the trend of the average of the particle number concentration measured by the NanoScan-SMPS agreed to within smalldifferences with the particle mass concentration of PM10 and PM2.5 measured by the EPMM. The 1hour-average PM10 andPM2.5 mass concentrations measured by EPMM were about 32.07 ?g/m3and 28.64 ?g/m3, respectively, and the 1hour-averagenumber concentration of sub-400 nm particle measured by the NanoScan-SMPS was found about 5,262.00 particles/m3. Particlesize distribution measured by the NanoScan-SMPS was found in the size range from about 11.5 to 365.2 nm. This proved thedeveloped system particularly useful as an online, low cost continuous monitor for the measurement of the mass and numberconcentrations and size distributions of ambient PM10, PM2.5 and sub-400 nm. |
