Biomimetic Photodegradation of Glyphosate in Carborane-Functionalized Nanoconfined Spaces

The removal of organophosphorus (OP) herbicides fromwater hasbeen studied using adsorptive removal, chemical oxidation, electrooxidation,enzymatic degradation, and photodegradation. The OP herbicide glyphosate(GP) is one of the most used herbicides worldwi ...

Modelling the effect of fluctuating herbicide concentrations on algae growth

Sylvain Coutu, Pierre-Jean Copin

Herbicide concentrations fluctuate widely in watercourses after crop applications and rain events. The level of concentrations in pulses can exceed the water chronic quality criteria. In the present study, we proposed modelling the effects of successive pu ...

Sulfamethoxazole and isoproturon degradation and detoxification by a laccase-mediator system: Influence of treatment conditions and mechanistic aspects

David Andrew Barry, Urs von Gunten, Christof Holliger, Jonas Margot, Pierre-Jean Copin

The potential of laccase-mediator systems (LMS) for the removal and detoxification of two wastewater micropollutants, the antibiotic sulfamethoxazole (SMX) and the herbicide isoproturon (IPN), was assessed. The influence of various parameters on micropollu ...

The Use of Passive Samplers to Reveal Industrial and Agricultural Pollution Trends in Swiss Rivers

Luiz Felippe De Alencastro, Nicolas Estoppey, Julien Omlin, Adrien Schopfer, Robin Udrisard

This study shows the efficiency of passive sampling to reveal industrial and agricultural pollution trends. Two practical applications for nonpolar and polar contaminants are presented. Low-density polyethylene (LDPE) samplers were deployed for one year in ...

Catchment-scale herbicides transport: Theory and application

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

This paper proposes and tests a model which couples the description of hydrologic flow and transport of herbicides at catchment scales. The model accounts for streamflow components' age to characterize short and long term fluctuations of herbicide flux con ...

The herbicide glyphosate and its metabolite AMPA in the Lavaux vineyard area, western Switzerland: Proof of widespread export to surface waters. Part II: The role of infiltration and surface runoff

Luiz Felippe De Alencastro

Two parcels of the Lavaux vineyard area, western Switzerland, were studied to assess to which extent the widely used herbicide, glyphosate, and its metabolite aminomethylphosphonic acid (AMPA) were retained in the soil or exported to surface waters. They w ...

The herbicide glyphosate and its metabolite AMPA in the Lavaux vineyard area, western Switzerland: proof of widespread export to surface waters. Part I: Method validation in different water matrices

Dominique Grandjean, Luiz Felippe De Alencastro

An analytical method for the quantification of the widely used herbicide, glyphosate, its main by-product, aminomethylphosphonic acid (AMPA) and the herbicide glufosinate at trace level was developed and tested in different aqueous matrices. Their derivati ...

Dynamics and environmental risk assessment of the herbicide glyphosate and its metabolite AMPA in a small vineyard river of the Lake Geneva catchment

Luca Rossi, Pierre-Jean Copin

The use of pesticides may lead to environmental problems, such as surface water pollution, with a risk for aquatic organisms. In the present study, a typical vineyard river of western Switzerland was first monitored to measure discharged loads, identify so ...

Diuron Sorbed to Carbon Nanotubes Exhibits Enhanced Toxicity to Chlorella vulgaris

Arnaud Magrez, Laura Sigg

Carbon nanotubes (CNT) are more and more likely to be present in the environment, where they, will associate with organic raicropollutants due to strong sorption. The toxic effects of these CNT-micropollutant mixtures on aquatic organisms are poorly charac ...

Occurrence and dynamics of micropollutants in a karst aquifer

Karst systems represent important yet vulnerable drinking water resources. A wide spectrum of pollutants may be released into karst groundwater from agriculture, livestock farming, private households, and industry. This work provides an overview on the occ ...

Multiple-endpoint assay provides a detailed mechanistic view of responses to herbicide exposure in Chlamydomonas reinhardtii

Kristin Schirmer, Renata Behra

The release of herbicides into the aquatic environment raises concerns about potential detrimental effects on ecologically important non-target species, such as unicellular algae, necessitating ecotoxicological risk assessment. Algal toxicity tests based o ...

Restoration of Threatened Arable Weed Communities in Abandoned Mountainous Crop Fields

Charlotte Vandenberghe, François Gillet

Arable fields maintaining species-rich weed communities have almost disappeared from European mountain areas due to their abandonment or replacement by extensive grazing systems during the last decades. The restoration of arable weed communities have becom ...

Immobilization of rapeseed press-cake in an alginate matrix for the sorption of atrazine

Urs von Stockar, Ian William Marison, Véronique Breguet, Julien Boucher

Due to residual oil retained within it, rapeseed press-cake has been shown to be effective for the removal of atrazine from water through an absorption mechanism. However, it is difficult to put this into practice due to the hygroscopic nature of the press ...

Diffuse release of environmental hazards by railways

Luca Rossi

There is increasing concern about environmental pollution by diffuse emissions of various environmental hazards emitted by transportation activities. For the first time substances released by railways to the environment were investigated. We considered the ...

The possible role of hydroxylation in the detoxification of atrazine in mature vetiver (Chrysopogon zizanioides nash) grown in hydroponics

Jean-Paul Schwitzguebel, Sylvie Vullioud-Marcacci

The resistance mechanism of vetiver (Chrysopogon zizanioides) to atrazine was investigated to evaluate its potential for phytoremediation of environment contaminated with the herbicide. Plants known to metabolise atrazinerely on hydroxylation mediated by b ...
