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 (2023) for further details.


12) Value at T = 293 K.
21) Several references are given in the list of Henry's law constants but not assigned to specific species.
52) Erratum for page 264 of Fogg and Sangster (2003): the second value from their Ref. [10] refers to 291.15 K, not 281.15 K.
53) This value is a correction of the solubility published by Lind and Kok (1986).
54) This value was measured at low pH. It is superseded by a later publication of the same group (Lind and Kok, 1994).
55) Pandis and Seinfeld (1989) cite an incorrect value from Lind and Kok (1986); see erratum by Lind and Kok (1994).
