Abstract
An environmental test chamber with controlled climate conditions is used to investigate the time dependence of total volatile organic compounds (TVOCs) emissions from 10 different consumer products, which are the most representative products available on the Australian market. TVOCs emissions from these consumer products are compared. The main volatile organic compounds (VOCs) emitted from some of these products are detected by GC/MS. A double-exponential model is developed to evaluate the characteristics of emissions of TVOCs from these consumer products. The double-exponential model facilitates an understanding of the mechanism of physical processes of the emission from consumer products and the calculation of a variety of emission parameters. The emission data obtained can be used to predict indoor air quality.
