Solar disinfection of viruses (SODIS): inactivation of coliphages MS2 and phiX174, human adenovirus and echovirus in water from Switzerland and India

Access to safe drinking water remains a challenge in many regions of the world. New methods to treat drinking water are constantly developped and improved in both in industrialised countries and in developing countries. SODIS is an interesting household-le ...

Optimizing turbine withdrawal from a tropical reservoir for improved water quality in downstream wetlands

Alfred Johny Wüest, Bernhard Wehrli

Large reservoirs in the tropics act as efficient nutrient traps and often develop hypoxic conditions in the hypolimnion. Both effects may have severe implications for aquatic ecosystems, such as limited primary production in downstream riparian agriculture ...

Quantification and characterization of dissolved organic nitrogen in wastewater effluents by electrodialysis treatment followed by size-exclusion chromatography with nitrogen detection

Urs von Gunten, Yun Ho Lee

Dissolved organic nitrogen (DON) can act as a precursor of nitrogenous disinfection byproducts during oxidative water treatment. Quantification and characterization of DON are still challenging for waters with high concentrations of dissolved inorganic nit ...

Sub-Antarctic marine aerosol: dominant contributions from biogenic sources

Julia Schmale

Biogenic influences on the composition and characteristics of aerosol were investigated on Bird Island (54°00' S, 38°03' W) in the South Atlantic during November and December 2010. This remote marine environment is characterised by large seabird and seal c ...

Biogeochemical processes and geotechnical applications: progress, opportunities and challenges

Lyesse Laloui

Consideration of soil as a living ecosystem offers the potential for innovative and sustainable solutions to geotechnical problems. This is a new paradigm for many in geotechnical engineering. Realising the potential of this paradigm requires a multidiscip ...

Chemical Oxidation of Dissolved Organic Matter by Chlorine Dioxide, Chlorine, And Ozone: Effects on Its Optical and Antioxidant Properties

Urs von Gunten, Silvio Canonica

In water treatment dissolved organic matter (DOM) is typically the major sink for chemical oxidants. The resulting changes in DOM, such as its optical properties have been measured to follow the oxidation processes. However, such measurements contain only ...

Ozonation of iodide-containing waters: Selective oxidation of iodide to iodate with simultaneous minimization of bromate and I-THMs

Urs von Gunten

The presence of iodinated disinfection by-products (I-DBPs) in drinking water poses a potential health concern since it has been shown that I-DBPs are generally more genotoxic and cytotoxic than their chlorinated and brominated analogs. I-DBPs are formed d ...

Formation of N-nitrosamines from chlorination and chloramination of molecular weight fractions of natural organic matter

Urs von Gunten, Ina Kristiana

N-Nitrosamines are a class of disinfection by-products (DBPs) that have been reported to be more toxic than the most commonly detected and regulated DBPs. Only a few studies investigating the formation of N-nitrosamines from disinfection of natural waters ...

An evaluation of surface micro and meso plastic pollution in pelagic ecosystems of western Mediterranean Sea

Luiz Felippe De Alencastro, Florian Faure, Pascal Hagmann

In the 90’s, the discovery of high concentrations of plastic debris in the oceans generated interest and concern of general public as well as scientific community. Since, the accumulation of plastic debris in the North Pacific and North Atlantic gyres has ...

Analysis of carbon and nitrogen dynamics in riparian soils: Model validation and sensitivity to environmental controls

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar, Pascal Niklaus

The Riparian Soil Model (RSM) of Brovelli et al. (Sci. Total Environ., this issue) was applied to study nutrient turnover in a revitalized section of the Thur River, North-East Switzerland. The model was first calibrated on field experimental data. The mod ...
