Mechanistic Understanding of Neurobehavioral Effects of Insecticides on the Larvae of Zebrafish (Danio rerio)

Due to conservation of neuronal functioning across phyla, molecular targets of insecticides are similar in insects and vertebrates. Insecticides thus pose a risk to aquatic vertebrates,such as fish, and potentially cause neurotoxic effects. Although these ...

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 ...

The influence of particles on bioavailability and toxicity of pesticides in surface water

Environmental risk assessment is an essential part of the approval process for pesticides. Exposure concentrations are compared with ecotoxicological data obtained from standardized laboratory studies and, if available, from field studies to determine the ...

Impact Assessment of Pesticides Applied in Vegetable-Producing Areas in the Saharan Zone

Edouard René Gilbert Lehmann

The present thesis aimed at characterizing the extent of the pesticide contamination and resulting impacts on the environment and the human health in market garden-ing areas in Burkina Faso. Analytical procedures were developed and validated for multi-clas ...

An analysis of lethal and sublethal interactions among type I and type II pyrethroid pesticide mixtures using standard Hyalella azteca water column toxicity tests

A novel 2-tiered analytical approach was used to characterize and quantify interactions between type I and type II pyrethroids in Hyalella azteca using standardized water column toxicity tests. Bifenthrin, permethrin, cyfluthrin, and lambda-cyhalothrin wer ...

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 ...

Picogram per liter detections of pyrethroids and organophosphates in surface waters using passive sampling

Juliane Hollender

Pyrethroids and organophosphates are among the most toxic insecticides for aquatic organisms, leading to annual-average environmental quality standards (AA-EQS) in the picogram per liter range in surface waters. For monitoring purposes, it is therefore cru ...

Comparing the effectiveness of chronic water column tests with the crustaceans

Standard U.S. Environmental Protection Agency laboratory tests are used to monitor water column toxicity in U.S. surface waters. The water flea Ceriodaphnia dubia is among the most sensitive test species for detecting insecticide toxicity in freshwater env ...

Esfenvalerate toxicity to the cladoceran Ceriodaphnia dubia in the presence of green algae, Pseudokirchneriella subcapitata

The presence of phytoplankton, like other particulate organic matter, can interfere with the effects of hydrophobic contaminants such as pyrethroid pesticides. However, the reduction or elimination of toxicity by algae added as food during testing is not t ...
