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.

1) A detailed temperature dependence with more than one parameter is available in the original publication. Here, only the temperature dependence at 298.15 K according to the van 't Hoff equation is presented.
3) The vapor pressure for water from Wagner and Pruss (1993) was used to calculate Hs.
12) Value at T = 293 K.
20) Calculated using machine learning matrix completion methods (MCMs).
21) Several references are given in the list of Henry's law constants but not assigned to specific species.
23) The partial pressure of water vapor (needed to convert some Henry's law constants) was calculated using the formula given by Buck (1981). The quantities A and α from Dean and Lange (1999) were assumed to be identical.
42) Fitting the temperature dependence dlnH/d(1/T) produced a very low correlation coefficient (r2 < 0.5). The data should be treated with caution.
188) The data presented for helium in Table II of Shoor et al. (1969) appear to be incorrect and are not reproduced here.
189) The data from Morrison and Johnstone (1954) were fitted to the three-parameter equation: Hscp= exp( −267.15298 +11440.04263/T +37.95994 ln(T)) mol m−3 Pa−1, with T in K.
190) The data from Lannung (1930) were fitted to the three-parameter equation: Hscp= exp( 84.35043 −4135.59197/T −14.55881 ln(T)) mol m−3 Pa−1, with T in K.
191) Calculated employing molecular force field models for the solutes from Warr et al. (2015).
192) The data from Dean and Lange (1999) were fitted to the three-parameter equation: Hscp= exp( −153.15219 +6434.36008/T +20.89911 ln(T)) mol m−3 Pa−1, with T in K.
