Popis: Despite their important contributions to primary aerosols and roles as precursors of secondary organic aerosols, emission data for different volatility classes of intermediate-volatility and semi-volatile organic compounds (IVOC/SVOC) from combustion sources are limited. This study reports gas and particle emissions measurements for a municipal solid waste incineration facility using online mass spectrometry (i.e., proton transfer reaction-time-of-flight mass spectrometer for the gas phase and soot particle aerosol mass spectrometer for the particle phase) and offline chemical analyses (e.g., gas chromatography–tandem mass spectrometry and liquid chromatography–tandem mass spectrometry) under a variety of isothermal dilution conditions to determine the volatility distributions of organic compounds. For the volatility distribution, which represents the total emission distribution of gases and particles as a function of saturation concentrations (C∗), the peak heights are nearly the same for volatile bins with C∗ = 0 μg m−3 and 105 μg m−3, and the sum of the emissions in those bins account for 40% of the emission amounts in the volatility range of low-volatility organic compounds to IVOC (10−2
