Hello,
        One of my students has been analyzing d18O in stream and soil
solution nitrates for a while now. We have been recently asked if we have
considered the possibility of isotopic exchange between NO3 oxygen and H2O
oxygen. Has anybody performed any studies in this direction?
Thanks!

Andrea
