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.


6) Only the tabulated data between T = 273 K and T = 303 K from Dean (1992) were used to derive Hs and its temperature dependence. Above T = 303 K, the tabulated data could not be parameterized very well. The partial pressure of water vapor (needed to convert some Henry's law constants) was calculated using the formula given by Sander et al. (1995). The quantities A and α from Dean (1992) were assumed to be identical.
7) Several references are given in the list of Henry's law constants but not assigned to specific species.
20) Value given here as quoted by Betterton (1992).
21) Bone et al. (1983) gives Carter et al. (1968) as the source. However, no data were found in that reference.

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