Ambient PM0.1, PM2.5 and PM10 were investigated at the roadside of Syuefu road in Hsinchu city and in the Syueshan highway tunnel in Taipei, Taiwan. A SMPS (TSI, 3936), three Dichotomous samplers (Andersen SA-241) and three MOUDIs (MSP 110) were collocated to determine the PM number or mass concentrations simultaneously. The filter samplers were further analyzed for organic carbon (OC), element carbon (EC), water-soluble ions and trace elements. The OC artifact was studied and quantified using the quartz behind quartz (QBQ) and quartz behind Teflon (QBT) methods for all PM fractions. Taking into account the OC artifact, chemical mass closure (ratio of the reconstructed chemical mass to the gravimetrical mass) of PM0.1, PM2.5 and PM10 was then calculated and the chemical characteristic of PMs was studied and compared at both sites.
