    Achieving a healthy indoor environment by using an emissions barrier for stopping spread of chemicals from building into the indoor air

     Johan Mattsson (corresponding) ,  Lennart Larsson (2021)
    An emissions barrier was used in premises with indoor air complaints due to emissions from the buildings in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood, and volatile organic compounds (VOC), mainly 2-ethylhexanol, from PVC flooring and the glue used to paste the flooring onto a concrete slab. Attaching the barrier at the surfaces from where the emissions were spread (floor, walls, ceiling) resulted in a fresh and odour-free indoor air. We conclude that using an emissions barrier in buildings made unhealthy by moisture is an efficient way of restoring a pleasant and healthy indoor air.

      Review text

      Introduction: 

      Airborne particles released from the building construction may be removed by using portable air cleaners with mechanical air filtration (HEPA etc) - Please provide HEPA abbreviation for the clarification.

      Results 1st installation:

      Also, the mouldy odour disappeared in the bedroom following the cTrap installation.  Is that a personal statement of the authors? If yes, please indicate that in the paragraph.

      General comment: Please keep air concentration unites consistant with the table 1 (µg/m3 not µg/m3). All air concentration unites should ideally be presented or as per ng or µg /m3 for consistency. 

      Results: 2nd  installation:

      There was a disturbing smell inside the building which persisted even after the tar had been removed. If possible, please provide more information about a smell. 

      Table 1:

      a) n.d. for chloroanisoles. Please provide the abbreviation of n.d. If not detected, please provide a limit of detection (LOD) for this compound.

      b) The unit of µg/m3  is not applicable for the 'emmisions'  table row but for 'without cTrap' and ' with cTrap' rows. Please modify it for the clarification.
