Quantitative structure–activity relationships (QSARs) for the transformation of organic micropollutants during oxidative water treatment

Various oxidants such as chlorine, chlorine dioxide, ferrateVI, ozone, and hydroxyl radicals can be applied for eliminating organic micropollutant by oxidative transformation during water treatment in systems such as drinking water, wastewater, and water r ...

50 years of ecotoxicology since Silent Spring - a review

In her book Silent Spring, Rachel Carson describes the cata strophic effects of the indiscriminate use of pesticides in the 1940s and 1950s. These substances, most of them insecticides, have since been designated as persistent organic pollutants and are re ...

Chemistry of Ozone in Water and Wastewater Treatment

Urs von Gunten

Even though ozone has been applied for a long time for disinfection and oxidation in water treatment, there is lack of critical information related to transformation of organic compounds. This has become more important in recent years, because there is con ...

Dominant controls on pesticide transport from tile to catchment scale: Lessons from a minimalist model

Andrea Rinaldo, Gianluca Botter

This paper proposes a minimalist modeling approach for characterizing pesticide concentrations in runoff from agricultural catchments across spatial scales. The model proposed is of an intermediate level of complexity between traditional chromatographic se ...

Determination of optimal conditions for the degradation of micropollutants by laccase from Trametes versicolor

David Andrew Barry, Christof Holliger, Julien Maillard, Luca Rossi, Jonas Margot

Many hydrophilic organic compounds present at low concentrations in municipal wastewater, such as several pharmaceuticals, biocides and pesticides, are recalcitrant in conventional wastewater treatment plants. To improve the biodegradation of these compoun ...

Impact of climate change on runoff pollution in urban environments

David Andrew Barry, Sylvain Coutu, Sébastien Kramer

Runoff from urban environments is generally contaminated. These contaminants mostly originate from road traffic and building envelopes. Facade envelopes generate lead, zinc and even biocides, which are used for facade protection. Road traffic produces part ...

Degradation of 37 emergent contaminants by UV and neutral fenton and photo-fenton in domestic wastewater effluent previously treated by activated sludge

César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Natalia de la Cruz

This study focuses on the removal of 32 selected micropollutants (pharmaceuticals, corrosion inhibitors and biocides/pesticides) found in an effluent coming from a municipal wastewater treatment plant (MWTP) based on activated sludge. Dissolved organic mat ...

Pollution due to plastics and microplastics in Lake Geneva and in the Mediterranean Sea

Luiz Felippe De Alencastro, Florian Faure, Hadrien Baecher, Marie Corbaz

Aquatic pollution due to plastics, and especially microplastics, is becoming the subject of growing research together with an increasing awareness of their environmental harm. While most of the studies focus on oceans, the situation regarding lakes remains ...

Enzymatic Conversion of epsilon-Hexachlorocyclohexane and a Heptachlorocyclohexane Isomer, Two Neglected Components of Technical Hexachlorocyclohexane

Christof Holliger

alpha-, beta, gamma-, and delta-Hexachlorocyclohexane (HCH), the four major isomers of technical HCH, are susceptible to biotic transformations, whereby only alpha- and gamma-HCH undergo complete mineralization. Nevertheless, LinA and LinB catalyzing HCl e ...

Who will clean up the environment from polychlorinated biphenyls?

Christof Holliger, Pierre Rossi, Martina Praveckova

PCBs are persistent, toxic and carcinogenic organic pollutants whose production was banned in the 80’s. Recently specific bacterial species were shown to degrade these compounds by attacking the bond between the aromatic core and the flanking chlorine atom ...
