Evaluation of the environmental fate and ecotoxicological impact of the pesticide chlorpyrifos in soil for improvement of its environmental risk asse…

EABIOMEUBINRA; Pesticides protect crops from various pests but can also harm nontarget organisms. To minimize risks for the environment and human health, a huge amount of studies are carried out and evaluated during the authorization process of each pesticide. However, the prediction of the environmental fate and ecotoxicological impact of a pesticide remains difficult. Several 100 formerly used pesticides are now banned because unexpected risks emerged decades after their authorization. Risk assessment documents of the organophosphate insecticide chlorpyrifos (CHL) particularly lack information about its degradation and potential transformation products in soil, and its impact on non-targe…

Developing and evaluating tools for assessing the impact of low-dose herbicide nicosulfuron on soil microbial diversity and functioning

2013

Today's conventinal agriculture still relies on the general use of pesticides. Even thought this guarantees production capabilities it also causes environmental pollution having impact on non-targeted organisms. Agricultural practices have been recognized by "The European Soil Framework Directive" as a major threat for soil biodiversity. However, without taking into consideration. recent methodological advances in microbiology, pesticide regulation at EU level relying solely on simple C and N mineralization tè-sts•. ln order to cope with this ECOFUN­-MICROBIODIV project .aim to develop and evaluate tools to estimate the impact of herbicide nicosulfuron on the function and population dynamic…

Ecotoxicological impact of pesticides on natural microbial communities responsible for pesticide biodegradation in river sediments

2014

International audience; The general use of pesticides in various crops allows ensuring the quality of the crop production but has environmental impact, pesticide residues being often found in water resources, notably river in the agrosystems. As a result of repeated exposure to pesticides microorganisms can adapt to their degradation being responsible for enhanced degradation, an environmental friendly process diminishing the persistence of pesticide residues in the environment. This process can occur in the soil but also in the sediment of the river regularly exposed to pesticide contamination. To our best knowledge the ecotoxicological impact of multiple pesticides contamination on the de…

Développement d’indicateurs microbiens pour l’évaluation de l’impact des pesticides sur des fonctions écosystémiques terrestres et aquatiques

2014

Les dernières évolutions réglementaires incitent les agriculteurs à diminuer le recours aux pesticides mais les pratiques agricoles en dépendent encore largement. Les conséquences environnementales de l’application de pesticides sont constatées par la détérioration de la qualité des masses d’eau. L’impact de la contamination des agrosystèmes par des résidus chimiques sur les fonctions remplies par la biodiversité reste peu décrit. Le projet IMPEC vise à développer des méthodes pour évaluer l’impact produit par des pesticides sur les communautés microbiennes terrestres et aquatiques ainsi que sur les fonctions écosystémiques qu’elles assurent.

Freshwater sediment pesticide biodegradation potential as an ecological indicator of microbial recovery following a decrease in chronic pesticide exp…

International audience; Water resources and aquatic ecosystems are an essential concern of any policy for sustainable development. In the context of the European Water Framework Directive, which aims to achieve good chemical and ecological status of waters, the herbicide diuron was banned in France in December 2008. In lotic ecosystems, benthic microbial assemblages are considered as useful potential indicators of ecological status because they integrate the effects of multiple anthropogenic disturbances and have strong capacities to adapt to novel environmental conditions. Field studies have thus revealed that in situ diuron exposure can induce microbial adaptation leading to an increase i…
