Figure 1: Layout of the third floor, PAH sources and sampling spots.
Figure 2: Absolute PAH content on SBSE devices after different
exposition times (wall; see Fig. 1, position S1), means and standard
deviations (n=3). 1st campaign: 29 July - 3 August;
2nd campaign: 23 – 30 September.
Figure 3: Absolute PAH content on
SBSE devices exposed for 24 h (11 – 12 September) on the floor with
different distances from the PAH source (see Fig. 1, position S3), means
and standard deviations (n=3).
Figure 4: PAH concentrations in air determined after pump sampling at
the wall (see Fig. 1, position P) in PU foams and quartz filters, means
and standard deviations (n=3). Intraday 1: 29 July; intraday 2: 11
September; interday: 30 July – 1 August.
