Figure 3 illustrates the relationship between personal TCA measurements and differences in FENO levels for each participant. The figure indicates the absence of a dose-response relationship.

Figure 2 displays pre- and post-shift FENO test results, illustrating variations in FENO levels among participants. On average, there was a change of +1.71 ppb between pre- and post-exposure.

Figure 1 shows the relationships between experimental personal TCA concentrations and measured static TCA concentrations for figure 1a and between experimental personal TCA concentrations and calculated static TCA concentrations for figure1b. A notably stronger association is observed (R² = 0.60) in figure 1b. This indicates that the calculated static TCA concentrations which takes into account the time spent in the different environments of the swimming pool provide a better estimate of personal TCA exposure over time for workers.
