«Analytical and environmental chemistry of toxins and bioactive metabolites from cyanobacteria»
Nitroaromatic explosives persist in the subsurface in different phases (e.g., bound to soil or sediment matrix or as solid-phase residues) and it is extremely challenging to assess biotic and mineral-catalyzed degradation. With the combined analysis of C, N, and H isotope fractionation, we can quantify transformation, even if it takes place via several potentially competing pathways over time-scales of decades.
Our research on fate of pharmaceuticals is motivated by investigating transformation pathways and kinetics to better understand the lifetime of such biologically active compounds in our freshwater Systems...

Predicting environment-specific biotransformation of chemical contaminants
Identification of transformation products and assessment of environmental relevance
N-nitrosamines such as N-nitrosodimethylamine (NDMA) are of public and regulatory concern because these potent carcinogens can be formed as unintented by-products during drinking and waste water disinfection/oxidation.
The extension of the CSIA approach to micropollutants is challenging for both analytical and conceptual reasons. In a collaborative SNF-Sinergia project, we aim at elucidating the fate of pesticides by multi-element isotope analysis on the field scale.
