Probabilistic environmental risk assessment of urban wet-weather discharges: an approach developed for Switzerland

Technical solutions aimed at limiting the impacts of urban wet-weather discharges are historically based on an end-of-pipe approach. The characteristics of wet-weather discharges, e. g. intermittent pollution loads, high variations in pollutant concentrati ...

Benzene dispersion and natural attenuation in an alluvial aquifer with strong interactions with surface water

Jordi Batlle-Aguilar, David Hunkeler

Field and laboratory investigations have been conducted at a former coke plant, discharging to an adjacent river, in order to assess pollutant attenuation in a contaminated alluvial aquifer. Various organic (BTEX, PAHs, mineral oils) and inorganic (As, Zn, ...

Mobility, turnover and storage of pollutants in soils, sediments and waters: achievements and results of the EU project AquaTerra. A review

Jordi Batlle-Aguilar, Hauke Smidt, Thomas Vogel

AquaTerra is one of the first environmental projects within the 6th Framework programme by the European Commission. It began in June 2004 with a multidisciplinary team of 45 partner organizations from 13 EU countries, Switzerland, Serbia, Romania and Monte ...

Locally-Resolved Study of Degradation in a SOFC Repeat- Element

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Zacharie Wuillemin, Arata Nakajo, Andres Müller

The locally-resolved degradation behavior was studied during 1900 hours in an SOFC repeat-element. In-situ measurements of local electrochemical performance were made on 18 locations over a segmented anode-supported cell. The evolution of local current den ...

New Metabolites in the Degradation of α- and γ-Hexachlorocyclohexane (HCH): Pentachlorocyclohexenes Are Hydroxylated to Cyclohexenols and Cyclohexenediols by the Haloalkane Dehalogenase LinB from Sphingobium indicum B90A

Christof Holliger, Thomas Geiger, Vishakha Raina

Technical hexachlorocyclohexane (HCH) and lindane are obsolete pesticides whose former production and use led to widespread contaminations posing serious and lasting health and environmental risks. Out of nine possible stereoisomers, α-, β-, γ-, and δ-HCH ...

Reactions of chlorine with inorganic and organic compounds during water treatment - Kinetics and mechanisms: A critical review

Urs von Gunten

Numerous inorganic and organic micropollutants can undergo reactions with chlorine. However, for certain compounds, the expected chlorine reactivity is low and only small modifications in the parent compound's structure are expected under typical water tre ...

Sorption of hydrophobic organic compounds (HOC) in rapeseed oil bodies

Ian William Marison, Julien Boucher

Oil-bodies are minute plant organelles (0.5-2.0 mu m diameter) consisting of an oil core surrounded by a phospholipid monolayer/proteinaceous membrane. Oil-bodies have been isolated from rapeseed seeds and demonstrated to constitute a novel type of micro-c ...

Ozonation of Source-Separated Urine for Resource Recovery and Waste Minimization: Process Modeling, Reaction Chemistry, and Operational Considerations

Urs von Gunten

Bench-scale, semibatch experiments were performed to examine physical-chemical constraints on ozone (O-3) absorption and micropollutant oxidation during ozonation of source-separated hydrolyzed urine and the concentrate and diluate streams produced via ele ...

Endocrine Disruptors and Breast Cancer

Cathrin Brisken

Breast cancer strikes one out of eight women in Switzerland. The increase in breast cancer incidence over the past 70 years parallels an enormous increase of man-made, persistent chemicals in our environment; some of which have endocrine-disrupting propert ...

Activation of the heat shock response in plants by chlorophenols: transgenic Physcomitrella patens as a sensitive biosensor for organic pollutants

Pierre Goloubinoff, Jean-Paul Schwitzguebel

The ability to detect early molecular responses to various chemicals is central to the understanding of biological impact of pollutants in a context of varying environmental cues. To monitor stress responses in a model plant, we used transgenic moss Physco ...
