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.
39) Lelieveld and Crutzen (1991) assume the temperature dependence to be the same as for a(H+)a(NO3)/p(HNO3) in Schwartz and White (1981).

H′ = 2.6×107×exp(8700 K ((1)/(T)−(1)/(T))) (mol2)/(m6 Pa) (see Errata!)


H′ = 2.4×107×exp(8700 K ((1)/(T)−(1)/(T))) (mol2)/(m6 Pa) (see Errata!)

42) The value is incorrect. See erratum (Brimblecombe and Clegg 1989).
43) Pandis and Seinfeld (1989) refer to Schwartz (1984) as the source but it is probably from Schwartz and White (1981).

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