摘要: Semi-continuous organic carbon (OC), elemental (EC), and molecular markers were analyzed using the thermal optical transmittance method at Gosan supersite (on Jeju Island, Korea), which has been widely used as a regional background site for East Asia. The Carbonaceous Thermal Distribution (CTD) method, can provide detailed signature characteristics relative to analytical temperature, was improve fractionation of method. Ground-based measurements conducted from October 25 November 5, 2010. During sampling period, one high OC concentration event two characteristic periods observed. Considering distribution patterns, relationship between EC black (BC) by measurements, backward trajectories, aerosol thickness, PM10 concentrations 316 PM-network sites that operated Ministry Environment in Korea, markers, such levoglucosan, PAHs, acids, we concluded influenced long-range transport biomass burning emissions. This study discusses CTD analysis with marker concentrations, extracts interprets additional fractions semi-continuous data set, provides knowledge regarding origin sources their behaviors.
