Restoration of Threatened Arable Weed Communities in Abandoned Mountainous Crop Fields

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 ...

Competitive advantage of Rumex obtusifolius L. might increase in intensively managed temperate grasslands under drier climate

Constant Signarbieux

Climate models predict decreasing amounts of precipitation for future summers in Switzerland. Since grasslands cover about one quarter of the area, severe consequences might be expected for Swiss agriculture, ranging from loss of grassland productivity to ...

Geochemical and hydrologic controls on the mobilization of arsenic derived from herbicide application

Janet Gordon Hering

The fate and transport of As was examined at an industrial site where soil- and groundwater contamination are derived from the application of As2O3 as a herbicide. Application of arsenical herbicides was discontinued in the 1970s and soils in the source ar ...

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 ...

A phytoremediation approach to remove pesticides (atrazine and lindane) from contaminated environment

The present thesis is part of a project exploring new possibilities to remediate soils polluted by insecticide lindane and herbicide atrazine. It is the Indo-Swiss project entitled "Development of Phytoremediation Techniques Using Interactive Potential of ...

Electrochemical decontamination of waters by advanced oxidation processes (AOPS): Case of the mineralization of 2,4,5-T on BDD electrode

Christos Comninellis, Pierre-Alain Michaud

In the present work, herbicide 2,4,5-trichlorophenoxyacetic acid, more commonly known as 2,4,5-T herbicide, has been completely mineralized (i.e. transformed into CO2 and H2O) in satd. aq. solns. using a semi-industrial electrochem. cell that contains a bo ...

Electrochemical destruction of chlorophenoxy herbicides by anodic oxidation and electro-Fenton using a boron-doped diamond electrode

Christos Comninellis

The degrdn. of herbicides 4-chlorophenoxyacetic acid (4-CPA), 4-chloro-2-methylphenoxyacetic acid (MCPA), 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) in aq. medium of pH 3.0 was comparatively studied by anodic oxi ...

A novel approach for the extraction of herbicides and pesticides from water using liquid-core microcapsules

Urs von Stockar, Ian William Marison

A perstraction system using liq.-core microcapsules for pesticide and herbicide removal from aq. environments is proposed. The microcapsules contain an oil, di-Bu sebacate, surrounded by a hydrogel membrane. The extn. efficiency of the capsules was demonst ...
