Chemosphere 57:863-70. 2004..About 5-10% of the HHCB was oxidised in the plant to HHCB-lactone. The dominant processes in the STP were sorption processes, though... - Polycyclic musks in the Ruhr catchment area--transport, discharges of waste water, and transformations of HHCB, AHTN and HHCB-lactoneKai Bester
Waste and waste water management, Institute of Environmental Analysis, University Duisburg Essen, Universitatsstrasse 15, 45141 Essen, Germany
J Environ Monit 7:43-51. 2005..In other rivers, such as the Rhine, higher levels of HHCB-lactone in comparison to HHCB were detected (ratio 1 : 1)... 
Activated soil filters for removal of biocides from contaminated run-off and waste-watersKai Bester
Department of Environmental Chemistry and Microbiology, National Environmental Research Institute, Aarhus University, Frederiksborgsvej 399, 4000 Roskilde, Denmark
Chemosphere 85:1233-40. 2011..Though the peat layer was responsible for most of the removal, the sand and gravel layers also contributed significantly for some compounds. All compounds are rather removed by degradation than by sorption...- Transformation products and reaction kinetics of fragrances in advanced wastewater treatment with ozoneNiklas Janzen
Department of Municipal Water and Waste Management, University Duisburg Essen, Essen, Germany
Chemosphere 85:1481-6. 2011..The reaction constants and half lives are used to predict removal efficiencies for full scale reactors... - Vertical flow soil filter for the elimination of micro pollutants from storm and waste waterNiklas Janzen
Institute of Environmental Analytical Chemistry, University Duisburg Essen, Universitätsstr 15, 45141 Essen, Germany
Chemosphere 77:1358-65. 2009..The elimination performance of the hydrophilic compound NBBS declined to 21%. Balancing studies including the soil of the filter system revealed that degradation or transformation were both relevant elimination mechanism... - Emissions of OTNE (Iso-E-super) - mass flows in sewage treatment plantsKai Bester
Institute of Environmental Analytical Chemistry, University Duisburg Essen, Universitätsstr 15, 45141 Essen, Germany
Chemosphere 71:2003-10. 2008..2 and 0.8 g per inhabitant which complies with data measured in 13 smaller STPs from Switzerland. The similarity of data suggests that the observed mass flow data might be extrapolated to other European regions... - Elimination of organophosphate ester flame retardants and plasticizers in drinking water purificationJens Andresen
Institute of Environmental Analytical Chemistry, Waste and Wastewater Management, University of Duisburg-Essen, , 45141 Essen, Germany
Water Res 40:621-9. 2006..The elimination effect of slow underground passage combined with soil passage concerning the halogenated compounds seemed to depend on the hydraulic residence time... - Persistence of antibiotics such as macrolides, tiamulin and salinomycin in soilMichael P Schlüsener

Environ Pollut 143:565-71. 2006..The concentration of roxithromycin remained nearly unchanged during the whole experiment... - Emerging pollutants in the North Sea in comparison to Lake Ontario, Canada, dataJens Arne Andresen
Institute for Environmental Analytical Chemistry, University Duisburg Essen, Universitiitsstrage 15, 45141 Essen, Germany
Environ Toxicol Chem 26:1081-9. 2007..The data seem to indicate either relevant inputs further west of the sampling area or mobilization from the sediments... - Determination of steroid hormones, hormone conjugates and macrolide antibiotics in influents and effluents of sewage treatment plants utilising high-performance liquid chromatography/tandem mass spectrometry with electrospray and atmospheric pressure chemMichael P Schlüsener
Waste and Wastewater Management, University of Duisburg Essen, Campus Essen, Universitaetsstr 15, D 45141 Essen, Germany
Rapid Commun Mass Spectrom 19:3269-78. 2005..6 to 1.8 ng/L. The maximum concentrations found in influents of a STP was 470 ng/L for estriol and 1200 ng/L for erythromycin... - Identification and quantification of pesticides, industrial chemicals, and organobromine compounds of medium to high polarity in the North SeaStefan Weigel
