Zusammenfassung |
A selection of models for estimating vapour pressures have been tested
against experimental data for a set of compounds selected for their
particular relevance to the formation of atmospheric aerosol by
gas-liquid partitioning. The experimental vapour pressure data (all
<100 Pa) of 45 multifunctional compounds provide
a stringent test of the estimation techniques, with a recent complex
group contribution method providing the best overall results. The
effect of errors in vapour pressures upon the formation of organic
aerosol by gas-liquid partitioning in an atmospherically relevant
example is also investigated. The mass of organic aerosol formed under
typical atmospheric conditions was found to be very sensitive to the
variation in vapour pressure values typically present when comparing
estimation methods. |
