I am looking forward to receiving information about additional data and bug reports from the scientific community. However, please don't be too disappointed in case I don't have the time to reply. Collecting Henry's law constants is not my main job. It's just something I did because I needed (and still need) them for my research. Before sending me an email, please consider the following points:
  • Converting between different definitions and units for Henry's law constants can be quite tricky. I'm afraid I won't have the time to answer individual questions on how to convert from unit xxx to unit yyy.
  • Henry's law constants are used in several research areas, e.g. pesticide control, waste water management, and atmospheric chemistry. Since I'm an atmospheric chemist myself, I don't think I will be able to help you with problems in the other research areas.

Compiling this data set would not have been possible without the help I received. For valuable discussions, bug reports, and also for pointing out and sending copies of additional references to me, I would like to thank C. Allen, W. Asman, G. Ayers, S. Balaz, M. Barth, J. Beauchamp, E. Betterton, S. Clegg, N. Couffin, P. J. Crutzen, F. Dentener, A. De Visscher, G. Hart, M. Hiatt, S. H. Hilal, R. Ingham, H. S. S. Ip, D. J. Jacob, H.-W. Jacobi, W. C. Keene, S. Lee, N. Lim, J. Matthijsen, J. Montgomery, R. M. Moore, M. Mozurkewich, F. Müller, E. O'Hare, O. Pahl, S. Pandis, J. Perlinger, J.-M. Régimbal, P. Riveros, E. Saltzman, S. E. Schwartz, W. Y. Shiu, T. A. Staffelbach, J. Staudinger, J. St-Pierre, G. Tyndall, J. Überfeld, C. Verlinde, R. Vogt, P. Warneck, and J. C. Wheeler. The Henry's Law Constants data base has been written using the open source software python, django and postgresql. Rüdiger Sörensen implemented the software on the web server of the satellite group. I am grateful to G. Mallard, S.  R.  Heller, and P. J. Linstrom for looking up many of the CAS registry numbers. The NIST Chemistry WebBook was also a very useful tool for this task.
