Interactions between effects of environmental chemicals and natural stressors: A review

Ecotoxicological effect studies often expose test organisms under optimal environmental conditions. However, organisms in their natural settings rarely experience optimal conditions. On the contrary, during most of their lifetime they are forced to cope wi ...

Metabolism of sulphonated anthraquinones in rhubarb, maize and celery: the role of cytochromes P450 and peroxidases

Jean-Paul Schwitzguebel

Sulphonated anthraquinones are precursors of many synthetic dyes and pigments, recalcitrant to biodegradation, and thus contaminating many industrial effluents and rivers. In the development of a phytotreatment to remove sulphonated aromatic compounds, rhu ...

Dualities in plant tolerance to pollutants and their uptake and translocation to the upper plant parts

Jean-Paul Schwitzguebel

There is a duality in plant tolerance to pollutants and its response to the pollutants’ stress. On the one hand some plants, (hyper)tolerant to heavy metals, are able to hyperaccumulate these metals in shoots, which could be beneficial for phytoremediation ...

Sulfur as Pollutant Species on the Cathode Side of a SOFC System

Jan Van Herle, Aïcha Hessler-Wyser, Zacharie Wuillemin, Josef Andreas Schuler

In order to link electrochemical performance degradation of the cathode in a large solid oxide fuel cell (SOFC) to the presence of pollutant species, a spatially-resolved study of contaminants was performed. Distribution maps of pollutants over the cell al ...
