Abstract:		"To accurately identify and locate ambient volatile organic compounds(VOCs)emission sources in industrial parks, a continuous online GC-FID method was used to monitor 43 kinds of VOCs on an hourly basis during January 2017 at five sites in an industrial park. A statistical analysis and a PMF model were used to analyze the sources of VOCs, and by combining with CPF and enterprise emission information, the location of each pollution source was accurately identified. The average VOCs concentration was 56.40x10(-9) and the highest concentration of alkanes was observed at four sites, with the exception of one site. Ethane, propane, ethylene, toluene, isobutane, n-butane, and acetylene were the main contributors. Ambient VOCs in the park mainly derives from five sources:urban transmission, butane leakage, process emissions, storage tank emissions, and ethylene synthesis. The enterprises in the zone B1, A1-A3, C1-C2, F4, E4-E6, F4-F6, and the canal loading and unloading area are the main emission areas of the pollution sources. Using online monitoring data, the research combined a PMF model, meteorological conditions, and corporate emissions information to achieve precise positioning of the pollution sources of VOCs in the industrial park, thus providing a basis for the supervision and management of corporate emissions in industrial parks"
