It is recently increasing that the amount of production and marketing of building materials with respect to its ability to reduce the concentration of indoor air pollutants in Korea. In this study, we evaluated performance for reduction of indoor air pollutants such as formaldehyde and toluene by sorptive building materials in domestic market. The test method using small-scale chamber is adopted. As a results, among the 23 building materials, 18 building materials had effectiveness for reduction of formaldehyde. And among the 23 building materials, 10 building materials had effectiveness for reduction of toluene. The mean sorption rate and total amount of sorption for formaldehyde were 36.8 % and 1,525.0 ㎍/㎡, respectively. The range of the sorption rate and total amount of sorption of formaldehyde were detected to 1.5~78.4 % and 87.5~3,086.0 ㎍/㎡ at 7 days after test, respectively. And the case of toluene, the mean sorption rate and total amount of sorption were 11.6 % and 1,054.0㎍/㎡, respectively. The range of the sorption rate and total amount of sorption of toluene were detected to 0.1~62.4 % and 29.6~6,764.0 ㎍/㎡ at 7 days after test, respectively. In almost all cases, formaldehyde re-emitted after sorption test. We confirmed that a surface structure, pore size and functional group of building materials have an effect on sorption of formaldehyde. This study includes that to suggest test method and evaluation criteria for building materials with respect to its ability to reduce the concentration of indoor air pollutants. The findings of this study could provide the Ministry of Environment (MOE) of Korea with fundamental knowledge on the establishment of management strategy for sorptive building materials.
