Research Questions

Redox processes play a key role in both biogeochemical cycles and for pollutant transformations. Thus, the overarching goal of this project is to identify and quantify the biogeochemical processes controlling the redox dynamics and thus the spatial and temporal transformation of redox sensitive nutrients (nitrate, ammonia) and agrochemicals (glyphosate, MCPA) in floodplain sediments.

 

Approach

We apply advanced electrochemical, trace analytical, microbial and biochemical techniques to determine


The work comprises field coring campaigns (in close collaboration with P3) as well as detailed laboratory studies to decipher and quantify the links between geochemistry, redox dynamics, microbial activity and pollutant fate.
