This seems like the relevant place to post this (could be wrong): Water plumes from Europa? Apologies if it's already been up. The link to the Science article at the bottom doesn't work for me, does anyone have a working link to the original? Cheers.

Some species will escape, and therefore thin out selected chemical elements at the surface.
(Hydrogen (besides helium) is the first element going lost by photolysis of water, leaving oxygen.)

Things will be rather complicated in detail. Here a paper which tries to simplify the processes for the Martian atmosphere, detailed photochemical reactions in Appendix A (p. 22ff).
The more chemical elements and transport processes have to be considered the more complicated.

Comet impacts may replace some of the lost surface material.
