Development of a modified QuEChERS method for multi-class pesticide analysis in human hair by GC-MS and UPLC-MS/MS

Luiz Felippe De Alencastro, Edouard René Gilbert Lehmann, Christelle Oltramare

The present study assessed the suitability of using QuEChERS procedure for the simultaneous deter- mination and quantification of 37 multi-class pesticides in human hair. Matrix co-eluted material had a large influence on instrumental response sensitivity. ...

Assessment of human exposure to pesticides by hair analysis: The case of vegetable-producing areas in Burkina Faso

Luiz Felippe De Alencastro, Edouard René Gilbert Lehmann, Christelle Oltramare, Jean-Jacques Stéphane Nfon Dibie

The present work assesses human exposure to pesticides in vegetable-producing areas in Burkina Faso, using hair as an indicator. The study design includes a comparison between operators who are occupationally exposed while working in the fields and a refer ...

Dietary risk assessment of pesticides from vegetables and drinking water in gardening areas in Burkina Faso

Luiz Felippe De Alencastro, Edouard René Gilbert Lehmann

Vegetables and water samples have been collected around the lake of Loumbila in Burkina Faso. Pesticides resi- dues in food commodities were analyzed using a modified QuEChERS extraction method prior analysis on GC-MS and UPLC-MS/MS of 31 pesticides. Maxim ...

Evaluation of the risk to groundwater after treating logs with cypermethrin

Dominique Grandjean, Luiz Felippe De Alencastro, Dimitri Dousse

In order to protect conifer logs against attacks from the striped ambrosia beetle (Trypodendron lineatum ) during spring in Swiss forests, logs are treated with the insecticide cypermethrin. Rainfall can cause the insecticide to leach into the ground, pote ...

Deposition and residues of azoxystrobin and imidacloprid on greenhouse lettuce with implications for human consumption

Anna Kounina Massé

Lettuce greenhouse experiments were carried out from March to June 2011 in order to analyze how pesticides behave from the time of application until their intake via human consumption taking into account the primary distribution of pesticides, field dissip ...

Phosphorylation of alpha-Synuclein at Y125 and S129 Alters Its Metal Binding Properties: Implications for Understanding the Role of alpha-Synuclein in the Pathogenesis of Parkinson's Disease and Related Disorders

Hubert Girault, Hilal Lashuel, Michel Prudent, Bruno Claude Daniel Fauvet, Yu Lu

alpha-Synuclein (alpha-syn) is a 140-amino acid protein that plays a central role in the pathogenesis of Parkinson's disease (PD) and other synucleinopathies. However, the molecular determinants that are responsible for triggering and/or propagating alpha- ...

Field solar degradation of pesticides and emerging water contaminants mediated by polymer films containing titanium and iron oxide with synergistic heterogeneous photocatalytic activity at neutral pH

César Pulgarin, Félicien Mazille

Photocatalytic degradation of phenol, nalidixic acid, mixture of pesticides, and another of emerging contaminants in water was mediated by TiO2 and iron oxide immobilized on functionalized polyvinyl fluoride films (PVFf-TiO2-Fe oxide) in a compound parabol ...

Toxicity assessment of the main pesticides used in Costa Rica

Raphael Charles

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 ...
