Table entries are sorted according to reliability of the data, listing the most reliable type first: L) literature review, M) measured, V) VP/AS = vapor pressure/aqueous solubility, R) recalculation, T) thermodynamical calculation, X) original paper not available, C) citation, Q) QSPR, E) estimate, ?) unknown, W) wrong. See Section 3.1 of Sander (2015) for further details.


31) Value at T = 295 K.
127) Solubility in sea water.
192) Effective value that takes into account the hydration of the aldehyde:
Hs= ([RCHO]+[RCH(OH)2])/p(RCHO)
197) Effective value suitable for the conditions of a case study in Mexico City.
198) Volkamer et al. (2009) found average effective Henry's law constants for CHOCHO in the range 1.6×106 mol/(m3 Pa) < Hscp < 5.9×106 mol/(m3 Pa) for solutions containing ammonium sulfate and/or fulvic acid. A salting-in effect by fulvic acid was observed even in the absence of sulfate.
199) Solubility in sulfate aerosol.
