The organic compounds collected on active carbon,Tenax GC and glass fiber film together with polyurethane foam are analyzed with GC/MS. It is proved that the concentration and the kinds of the pollutant emitted to the ambient air from refined beau oil are less than those from secondary beam oil. Therefore, the use of refined beau oil is beneficial to envirnmental protection and human health.Keywords: edible oil; organic constituents; GC/MS
