Type

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.

Notes

14)	Value at T = 310 K.
21)	Several references are given in the list of Henry's law constants but not assigned to specific species.
68)	Modarresi et al. (2007) use different descriptors for their calculations. They conclude that a genetic algorithm/radial basis function network (GA/RBFN) is the best QSPR model. Only these results are shown here.
186)	Experimental value, extracted from HENRYWIN.
421)	HSDB (2015) refers to Abraham et al. (1994b) as the source, but this value cannot be found there. Maybe the value is taken from Abraham et al. (1990).
775)	The data from Smith et al. (1981b) were fitted to the three-parameter equation: H_s^cp= exp( 678.00770 −27346.39638/T −103.92351 ln(T)) mol m⁻³ Pa⁻¹, with T in K.
