Hydrochemical indicators of water source and contamination in fen peatlands of varying hydrogeomorphic settings in northern and central Poland

In this study, we considered 41 fens located in northern and central Poland. In our main hypothesis, we assumed that the base chemical composition of fen waters primarily depends on the hydrological regime, indicating a relationship to morphogenetic type of fen. We analyzed 40 physicochemical parame...
