Greetings!

I would like to determine the natural abundance of 15N of ammonium in
interstitial water and overlying water in brackish lake.

I would greatly appreciate any information i.e. literatures, name of the
expert person, or key words to search papers. Searching with key words of
"ammonium" and "stable isotope" gave me too much papers of no relations.

Sincerely,
Masumi
