The purpose of this research is to characterize airborne asbestos and radon concentrations as trace toxic air pollutant in the underground spaces in Gyungnam province. Air samples of asbestos and radon were taken in the three underground spaces for ten months from April 2003 to January 2004. The IAQ(Indoor Air Quality) of underground spaces were controlled using central ventilation (supply/ exhaust) system. The levels of geometric means of airborne asbestos and radon concentrations in three sampling spaces were below the standards of Korean Ministry of Environment. However, one sample of airborne asbestos in underground spaces "C", which was used fire proofing fibrous material, was in excess of the standard. There are significantly statistical differences in levels of trace toxic air pollutants by sampling spaces(p<0.05).
