Emissions from the galenic production (GalPro) of pharmaceuticals can lead to concentration peaks of active ingredients in wastewater treatment plant (WWTP) effluents...
Comprehensive monitoring of organic trace substances in surface waters is time-consuming and costly. The NAWA SPEZ project delivers data and analyses on the status of water pollution.
...is an inter- and trans-disciplinary research project, studying environmental, health and institutional dimensions of pesticide use in tropical settings
Identification and quantification of species in the vast and diverse universe of organic micropollutants is a daunting challenge for environmental sciences...
Various aquatic organisms produce extracellular biomolecules, e.g., enzymes to catalyze reactions, chelators to transport metals, or toxins to fight competitors...
Previous studies monitoring micropollutant concentrations in aquatic invertebrates revealed tissue concentrations of many compounds to be substantially higher than predicted from models...
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...
Identification and quantification of species in the vast and diverse universe of organic micropollutants is a daunting challenge for environmental sciences...
The screening of aquatic systems for known and unknown polar and semi-polar organic micropollutants relies heavily on analytical chemistry, foremost high-resolution mass spectrometry (HRMS) coupled to liquid chromatography (LC)....
According to the Swiss constitution, the Swiss agriculture has to fulfill several, partially conflicting goals such as agricultural production on the one hand and ...
The river Rhine and its tributaries are a source of drinking water for more than 20 million people. At the same time treated waste water from numerous industrial sites and from the 54 million people living in the catchment area ends up in the rivers...
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.
A contemporary view of rivers recognizes them as having multiple vertical and lateral flow paths serving as bidirectional links to the surrounding landscape...
Site-specific chemical and bioassay monitoring of micropollutants (MPs) are desirable, but the large number and diversity of MPs, and the cost and technical issues of measuring them, make the exposure assessment challenging
