Characterizing and quantifying the exposure of an agricultural area to pesticides as part of the “One Health” initiative
My name is Frédéric OUEDRAOGO. I am a geochemist. During my academic training (master and doctorate), I was interested in the behavior of chemical elements in the environment, in order to understand their ecotoxicity. My doctoral thesis focused on the behavior of copper (Bordeaux mixture) in the soils of vineyards.
I am recruited in the Resilience Team of the CEBC since December 2022 and administratively attached to the Epicene team of Inserm of Bordeaux. This recruitment is part of the « Santé du Territoire » program. The objective of the Resilience team is to actively participate in the transformation of a territory to make it more resilient to crises, which are expected to be more frequent. This territory is the Zone Atelier Plaine & Val de Sèvre (ZAPVS). The Epicene team is developing research on the links between exposure to environmental and occupational nuisances (pesticides in this case) and the occurrence of cancers. The project relies on a partner cohort made up of inhabitants, farmers and health personnel. Given the trans and multidisciplinary dimension of the project, I interact with many actors with diverse skills.
My work is mainly focused on the Agriculture-Environment-Health interfaces and focuses on the Pressure-Exposure-Impact chain of pesticides. It is more and more accepted that the notion of health must be global and complete. Global Health (or One Health) includes the health of humans, biodiversity and the environment. Indeed, a balance results from the interconnections between the health of these 3 entities of a socio-ecosystem. However, the use of pesticides as a result of agricultural intensification can affect this balance and harm the health of the socio-ecosystem. My role in the project is to characterize the “pressure-exposure” link (bioaccumulation, detoxification) and the “exposure-impact” link (dietary behaviors, cocktail effects) of pesticides in the villages of the ZAPVS selected for the study. Ultimately, all these activities should contribute to operationalize the concept of “One Health”.
My postdoctoral mission consists of: – Develop a list of the most frequently and abundantly found pesticides in the ZAPVS using the data bank built up over the years – Adapt or develop sampling protocols for the project – Participate in the collection of field samples (soil, water, insects, etc.) – Participate in the collection and the analysis of data from surveys or chemical assays – Participate in the coordination of activities with other project partners – Contribute to the scientific valorization (articles, conferences) and to the restitution of the final results of the project.
