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.


7) Several references are given in the list of Henry's law constants but not assigned to specific species.
9) Value at T = 293 K.
28) Value at T = 288 K.
84) Value given here as quoted by Abraham et al. (2008).
85) Petersen et al. (1998) give the invalid unit "mol L−1 ppm−1". Here, it is assumed that "ppm" is used as a synonym for "10−6 atm".

The numbers of the notes are the same as in Sander (2015). References cited in the notes can be found here.
