Assessing the emission of organic compounds from building and furnishing materials via small test chambers
The equipment and the procedure employed for the qualitative and quantitative determination of the volatile organic compounds (VOC) emitted from samples of building and furnishing materials are described. The equipment includes two small test chambers (0.45 m3), with accurately controlled temperature, relative humidity and air flow rate, and instrumentation for sampling and analysis (Tenax(R) tubes, GC-FID and GC-MS). To find quasi steady state emission conditions, the procedure includes the determination of the time profiles of the organic compounds concentrations, which develop after the introduction of the samples in the chamber. A best fitting double exponential equation is used for this purpose. The procedure has been applied to three building materials: particle board with carpet, gypsum board with wall paper and plywood with polyurethane lacquer, for which the steady state emission factors (mg/m2.h)) of several compounds are given. Many other compounds were identified, but not quantified.
