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.
87) Value at T = 333 K.
88) Calculated using linear free energy relationships (LFER).
89) Measured at high temperature and extrapolated to T = 298.15 K.
90) More than one reference is given as the source of this value.

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