Journal ArticleDOI
The Challenge of Micropollutants in Aquatic Systems
René P. Schwarzenbach,Beate I. Escher,Kathrin Fenner,Thomas B. Hofstetter,C. Annette Johnson,Urs von Gunten,Bernhard Wehrli +6 more
TL;DR: There are three scientific challenges in addressing water-quality problems caused by micropollutants, and usage and disposal strategies should aim to minimize introduction of critical pollutants into the aquatic environment.
Journal ArticleDOI
Global Water Pollution and Human Health
TL;DR: In this paper, the main groups of aquatic contaminants, their effects on human health, and approaches to mitigate pollution of freshwater resources are reviewed, particularly on inorganic and organic micropollutants including toxic metals and metalloids as well as a large variety of synthetic organic chemicals.
Journal ArticleDOI
Vanadyl in natural waters: Adsorption and hydrolysis promote oxygenation
Bernhard Wehrli,Werner Stumm +1 more
TL;DR: Wehrli and Stumm as mentioned in this paper showed that the rate of oxidation of VO2+ by oxygen is significantly enhanced by hydrolysis or adsorption to hydrous oxide surfaces and showed that coordinated OH-groups of solid surfaces are able to mediate the electron transfer from the metal ions to the O2-molecule.
Journal ArticleDOI
Organic carbon burial efficiency in lake sediments controlled by oxygen exposure time and sediment source
Sebastian Sobek,Sebastian Sobek,Edith Durisch-Kaiser,Edith Durisch-Kaiser,Roland Zurbrügg,Roland Zurbrügg,Nuttakan Wongfun,Nuttakan Wongfun,Martin Wessels,Natacha Pasche,Natacha Pasche,Bernhard Wehrli,Bernhard Wehrli +12 more
TL;DR: In this article, the authors compared the burial efficiency of organic carbon (buried OC: deposited OC) in a diverse set of 27 different sediments from 11 lakes, focusing on the potential effects of organic matter source, oxygen exposure, and protective sorption of OC onto mineral surfaces.
Journal ArticleDOI
Anaerobic ammonium oxidation in a tropical freshwater system (Lake Tanganyika).
Carsten J. Schubert,Edith Durisch-Kaiser,Bernhard Wehrli,Bo Thamdrup,Phyllis Lam,Marcel M. M. Kuypers +5 more
TL;DR: Incubations with (15)N labelled nitrate showed that anammox occurred in the suboxic water layer at 100-110 m water depth, providing the first direct evidence for the anamm ox process (anaerobic ammonium oxidation) in a lacustrine system, Lake Tanganyika, the second largest lake in the world.
