【Abstract】 猅he volatile organic compounds (VOCs) in indoor air were analysed qualitatively with gas chromatography/mass spectrometry (GC/MS);and the concentrations of alkyl benzenes were determined through sampling by activated carbon adsorption and quantitative analysis by GC/FID.The sources of VOCs and the change trend of pollutant concentrations were conducted.In simulated study ,the emissions of some sources including decorative materials and chemicals for everyday use and the sink effect of alkyl benzenes were tested.A mathematical model and its parameters were given;and the adsorptiondesorption rate coefficient was formulated to describe the emission and the sink effect of alkyl benzenes in indoor environment.更多还原
