Abstracts
This study was performed to evaluate the type and concentration of TVOC and formaldehyde emitted from asbestos stabilizers, because the stabilizers can be applied on the surface of asbestos contained building materials(ACBM). The emission test of three organic and synthetic resins(OSBS) and five inorganic based stabilizers(IBS) were tested for 7 days. The amount of emission and concentrations of TVOC were measured using GC/FID and GC/MS. In case of formaldehyde, quantitative analysis was carried out using HPLC. The average concentrations of TVOC and formaldehyde of 8 stabilizers were 1.173 mg/m2․h and 0.007 mg/m2․h, respectively. The maximum TVOC concentration among five OSBS was 5.698 mg/m2․h and exceeded the TVOC emission standard(4.0 mg/m2․h) for general building materials. According to the this study results, the applied stabilizer can be role one of pollutant sources like paints, floor tile etc. The emission test has to be tested one of stabilizers efficiency to manage the indoor air quality of building
