    Spatial-temporal Characteristics and Source Apportionment of Ambient VOCs in Southeast Mountain Area of China by Xiaoting Ji, Ke Xu, Dan Liao, Gaojie Chen, Taotao Liu, Youwei Hong, Sijun Dong, Sung-Deuk Choi, Jinsheng Chen

    Published 2022-03-01
    “…Source apportionment of VOCs were quantified by the positive matrix factorization (PMF) model, including industrial emissions and combustion burning (30.1% and 43.3% in the county and rural areas, respectively) and vehicle exhausts (30.3% and 10.8%), followed by solvent usage (17.1% and 5.2%), liquid petroleum gas (LPG) usage and fuel evaporation (14.2% and 10.0%), and biogenic source (8.3% and 30.6%). The backward air trajectories showed that air mass in spring was mainly originated from the intercity transmission, while the air clusters in autumn came from the northern areas through long-range transport. …”
