英文摘要	Using 2017 data, 54 volatile organic compounds (VOCs) in Taiwan's atmospheric environment from nine photochemical assessment monitoring stations (PAMSs) were collected and their characteristics and sources were analyzed. High VOC concentration spots were exposed in urban and industrial areas (Wanhua, Tucheng, Chungming, Tainan, Qiaotou, and Xiaogang). The major categories of VOC were alkanes and aromatics. Among them, benzene, toluene, ethylbenzene, and m,p-xylene (BTEX) predominated and contributed to ozone formation potential (OFP) and secondary organic aerosol formation (SOAF). T/B and X/E ratios showed that VOCs in urban and industrial areas originated from fresh, mixed sources of local emissions. Positive matrix factorization (PMF) analysis indicated that industrial emissions (solvent usage, industry, and petrochemical plant) were the primary contributors, followed secondarily by traffic emissions (vehicular emission and vehicular fuel evaporation), and aged air-mass. Analysis by potential source contribution function (PSCF) was conducted to confirm the effects of aged air-mass sources. The estimated VOC sources OFP and SOAF indicated that industrial emissions were the greatest contributors to OFP and SOAF. Results from this study imply that VOC control measures should prioritize control of industrial emissions. © 2020
