Using an emissions barrier for controlling PAH in indoor air

Lehtimaa, Timo ; Mattsson, Johan and Larsson, Lennart LU (2022) 17th International Conference on Indoor Air Quality and Climate, INDOOR AIR 2022
Abstract

An emissions barrier was installed in a building where a wall had been treated with a tar-containing material as an impregnation agent and moisture barrier. There was a strong disturbing smell inside the building. Several polycyclic aromatic hydrocarbons (PAH) were identified in the indoor air amounting to a total of 1726 ng PAH/m3. The amounts decreased to 139 ng/m3 after the barrier had been installed on about 75 percent of the wall surface, and there were no longer complaints regarding odour. We conclude that an emissions barrier with an adsorbent layer may be useful in reducing air concentrations of potentially carcinogenic PAH in buildings containing tar and creosote.
