The aim of this thesis was to develop a new type of liquid-core capsules obtained by co-extrusion using the laminar jet break-up technique. These capsules, composed of an organic phase as the core and a hydrogel membrane, were meant to be applied as an in- ...
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 ...
The impacts of the 30 active substances, most used in Costa Rica (reference year 1998), are evaluated using two models originally developed to support comparative assertions in the context of the life cycle assessment: the multimedia fate, exposure and eff ...
This work is a contribution to the development of a specific method to assess the presence of residues in agricultural commodities. The following objectives are formulated: to identify and describe main processes in environment — plant exchanges, to build ...
Background, aim, and scope Current knowledge on environmental impacts of industrial activities in Romania, particularly persistent organic pollutants (POPs), indicates that environmental standards of the European Union are not systematically met. In our st ...
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 ...
Objective: The MRL mouse strain shows extraordinary wound healing capacities. Some years ago, Leferovich et al. (Proc Natl Acad Sci U. S. A. 2001;98:9830-35) have reported the absence of scar formation after cryogenically-induced right ventricular myocardi ...
The herbicide transport and the groundwater vulnerability to pesticide contamination were studied in the alluvial aquifer of the Rhône River Valley near Martigny (Southwest Switzerland). The low clay and organic matter content of the soil, the intensive ag ...
Nostocarboline (I) and seven derivatives were prepared and displayed minimal inhibitory concn. (MIC) values >=100 nM against the growth of Microcystis aeruginosa PCC 7806, Synechococcus PCC 6911, and Kirchneriella contorta SAG 11.81, probably via the inhib ...
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 ...
