To observe the convergence of the mean gas-phase concentration, samples taken near the releasing source and after an extended period were employed as reference points for geraniol, given that variations under these conditions are more pronounced, as depicted in To first understand how the vapor pressure and diffusivity uncertainties affect the predictions, the mean gas phase concentration and 99% credible interval (spanning the 5th to 99.5th percentiles) at a 100cm distance from the liquid-gas interface is displayed in Figure for crude Monte Carlo samples. It can be seen that predictions can differ by orders of magnitude with amplifying intervals as time evolves. The least pronounced amplitude of the credible interval is related to ethanol, as expected due to its lower variance in the vapor pressure point predictive distribution. Similar figures were plotted to illustrate the same conclusions at different positions from the liquid source and are displayed in the Appendix A.
