Abstract: Volatile organic compounds (VOCs) are important precursors of urban secondary organic aerosol (SOA) and ozone (O3) pollution. Industrial parks are important sources for anthropogenic VOCs, with main fugitive emission of characteristic pollutants such as alkanes, alkenes and aromatic hydrocarbons and so on. To effectively control VOCs emission from industrial parks and evaluate the effects of control and treatment, it is necessary to monitor the flux and distribution of VOCs emission. Solar occultation flux (SOF) technique is currently one of the best available techniques for monitoring fugitive emission flux of field VOCs. The principle, method, development and applications of SOF technique are introduced in detail in this review, and the future application of SOF in monitoring VOCs emission flux from industrial parks in China is prospected as well.

Key words: volatile organic compounds, fugitive emission, flux, solar occultation flux, solar tracker
