Post-doctoral researcher in ecotoxicology W/M

The university of Bordeaux is a great dynamic and responsible university that cares about the well-being of its staff. Joining us means working in a privileged environment within a particularly diverse and open professional community, benefiting from welcome and inclusion schemes, training and internal mobility. It means participating in an academic, scientific and human adventure. It means committing to meeting the challenges of the 21st century.

Join the laboratory Oceanic and Continental Environments and Palaeoenvironments ( EPOC ) This laboratory is a Joint Research Unit under the joint supervision of the University of Bordeaux, CNRS, Bordeaux INP and the Ecole Pratique des Hautes Etudes. EPOC is a multidisciplinary UMR developing a strong and recognized expertise in ecotoxicology, ecology, biogeochemistry, environmental chemistry, sedimentology, paleoclimatology, coastal oceanography, marine geosciences.

As part of the NetImpact project, engaged by the National Research Agency, we are recruiting a Post-Doctoral researcher in ecotoxicology F/H whose research will focus on the evaluation of toxicity and characterization of effects of new biodegradable nets for marine mussel farming.

This project aims to study the environmental and health impacts related to the use of plastics in aquaculture, particularly protective nets used in the farming of marine mussels on bouchot, by focusing on bio-based alternatives - biodegradable, considered more sustainable and less harmful to ecosystems. It therefore aims to ensure that they do not pose additional risks to marine ecosystems or human health.

Your mission will aim to characterize and compare the effects of biosourced biodegradable plastic protective nets compared to conventional plastics, before and after aging in a UV chamber or immersion in a natural environment (mesocosm). Toxicity and induced effects will be characterized on the blue mussel Mytilus edulis at two developmental stages: embryo-larval and adult, using both phenotypic, biochemical and physiological analyses.

You will be supervised by Jérôme CACHOT.

Study of the toxicity of particles, additives and leachates from plastic nets on blue mussel embryos and larvae

• You expose them under controlled laboratory conditions
• You measure the effects on development, growth, and mobility

Study of ecotoxic effects and adaptive responses of adult mussels exposed to plastic nets

• You are exhibiting mussels in mesocosome (Lab. LOG, Littoral University of the Opal Coast)
• You carry out in situ measurements of the effects on survival, growth, and filtration activity
• You analyze biochemical responses (oxidative stress) and the content of proteins, lipids, and glycogen

Supervision of trainees for the study of the toxicity of particles, additives and leachates of plastic nets on bacteria and marine microalgae (standardized tests)

Analysis and evaluation of results

• You conduct a statistical analysis and interpret the results
• You contribute to the writing of scientific articles
• You present your results at scientific and public conferences

You will carry out missions in the field.

Holder of a PhD in in Environmental Sciences and more precisely in ecotoxicology and ecophysiology, you have developed knowledge in animal physiology.

• You are trained in animal testing and have already practiced on aquatic animals
• You have knowledge of statistics
• You are proficient in English in a multicultural work context (minimum B2 level)
