Triclosan: occurrence and fate of a widely used biocide in the aquatic environment: field measurements in wastewater treatment plants, surface waters, and lake sedimentsHeinz Singer
Swiss Federal Institute for Environmental Science and Technology EAWAG, Uberlandstrasse 133, CH 8600 Dübendorf Switzerland
Environ Sci Technol 36:4998-5004. 2002..As the measured concentrations in surface waters are in the range of the predicted no effect concentration of 50 ng/L, more measurements and a detailed investigation of the degradation processes are needed...
High-throughput identification of microbial transformation products of organic micropollutantsDamian E Helbling
Eawag, Swiss Federal Institute of Aquatic Science and Technology, 8600 Dubendorf, Switzerland
Environ Sci Technol 44:6621-7. 2010..The results showed that the complementary use of the target and non-target screening methods allowed for a more comprehensive interpretation of the TPs generated than either would have provided individually...- Elimination of organic micropollutants in a municipal wastewater treatment plant upgraded with a full-scale post-ozonation followed by sand filtrationJuliane Hollender
Eawag, Swiss Federal Institute of Aquatic Science and Technology, Dubendorf, Switzerland
Environ Sci Technol 43:7862-9. 2009..The energy requirement for the additional post-ozonation step is about 0.035 kWh m(-3), which corresponds to 12% of a typical medium-sized nutrient removal plant (5 g DOC m(-3))... - Targeting aquatic microcontaminants for monitoring: exposure categorization and application to the Swiss situationChristian W Götz
Eawag, Swiss Federal Institute of Aquatic Science and Technology, Ueberlandstrasse 133, 8600, Dubendorf, Switzerland
Environ Sci Pollut Res Int 17:341-54. 2010..The presented substance categorization methodology is based on the chemicals' distribution behavior between different environmental media, degradation data, and input dynamics... - Passive sampling combined with ecotoxicological and chemical analysis of pharmaceuticals and biocides - evaluation of three Chemcatcher configurationsEtiënne L M Vermeirssen
Eawag, Swiss Federal Institute of Aquatic Science and Technology, Uberlandstrasse 133, 8600 Dubendorf, Switzerland
Water Res 43:903-14. 2009..The membrane causes a lag phase of up to 2.3 days which thwarts a sound interpretation of data from sampling periods of less than 10 days... - Including mixtures in the determination of water quality criteria for herbicides in surface waterNathalie Chèvre
Swiss Federal Institute for Aquatic Science and Technology Eawag, Duebendorf, Switzerland
Environ Sci Technol 40:426-35. 2006.... - Loss rates of urban biocides can exceed those of agricultural pesticidesIrene K Wittmer
Eawag, Swiss Federal Institute of Aquatic Science and Technology, 8600 Dubendorf, Switzerland
Sci Total Environ 409:920-32. 2011..g. diazinon) showed a continuous load independent of rain events and season. This study demonstrates that in catchments with mixed land use, mitigation strategies have to pay sufficient attention to the urban sources... - Comparison of atrazine losses in three small headwater catchmentsChristian Leu
Swiss Federal Institute for Environmental Science and Technology (EAWAG, Ueberlandstrasse 133,
J Environ Qual 34:1873-82. 2005..Hence, the study results provide a good data set to evaluate distributed models predicting herbicide losses... - Surface runoff and transport of sulfonamide antibiotics and tracers on manured grasslandMichael Burkhardt
Department of Water and Agriculture, Swiss Federal Institute for Environmental Science and Technology (EAWAG, Uberlandstrasse 133, , Switzerland
J Environ Qual 34:1363-71. 2005..Hence it is important to consider explicitly the physical and chemical effects of manure when assessing the environmental fate of sulfonamides... - Variability of herbicide losses from 13 fields to surface water within a small catchment after a controlled herbicide applicationChristian Leu
Swiss Federal Institute for Environmental Science and Technology (EAWAG) and Swiss Federal Institute of Technology (ETHZ, Uberlandstrasse 133, , Switzerland
Environ Sci Technol 38:3835-41. 2004..These results illustrate the large potential to reduce herbicide losses by avoiding application on risk areas... - Simultaneous assessment of sources, processes, and factors influencing herbicide losses to surface waters in a small agricultural catchmentChristian Leu
Swiss Federal Institute for Environmental Science and Technology (EAWAG) and Swiss Federal Institute of Technology (ETHZ, Uberlandstrasse 133, , Switzerland
Environ Sci Technol 38:3827-34. 2004..e., approximately 8 microg L(-1) for a short period (<2 h) due to point source losses and between 1 and 3.5 microg L(-1) during more than 24 h due to diffuse losses)... - Mixture toxicity of three photosystem II inhibitors (atrazine, isoproturon, and diuron) toward photosynthesis of freshwater phytoplankton studied in outdoor mesocosmsStefanie Knauert
Department of Environmental Sciences, University of Basel, 4056 Basel, Switzerland
Environ Sci Technol 42:6424-30. 2008..Declining effects on photosynthetic activity during the experiment might be explained by both a decrease in water herbicide concentrations and by the induction of community tolerance...
