General information

Reference : UMR7266-HELTHO-001
Workplace : LA ROCHELLE
Date of publication : Friday, October 1, 2021
Type of Contract : FTC Scientist
Contract Period : 12 months
Expected date of employment : 1 December 2021
Proportion of work : Full time
Remuneration : 2 000 €
Desired level of education : 5-year university degree
Experience required : 1 to 4 years


We are looking for an enthusiastic post-doctoral researcher to participate in a research program (1 year contract) conducted within the framework of the FEAMP PLASTIC LAB project of the LIENSs Laboratory. The FEAMP PLASTIC-LAB project consists of an experimental pilot phase making it possible to provide first innovative results on the behavior of aged and / or naïve plastics. The objectives will be to assess the degradability of shellfish plastics over time, to characterize the level of toxicity of shellfish plastics & develop an identity card, for each shellfish "aged" in the environment, aiming to identify and quantify the persistent organic pollutants vectorized on the surface of these plastics.


This project on macroplastics of shellfish origin found on the coasts of Pertuis Charentais (consequence of losses and stalling in production areas) proposes two experimental approaches. A first study will characterize the structure (fragility, breaks) of shellfish plastics over time and identify the degradation of plastics into microparticles over time (water and sediment analyzes).
Secondly, this work will seek to quantify & identify the persistent organic POP pollutants (phthalate additives, metals, pesticides, hydrocarbons, endocrine disruptors) present on the oyster plastics tested, potentially more toxic than the polymers themselves. Sampling and analysis campaigns will be set up (n = 9) in order to have a kinetics of vectorization of POPs on the surface of plastics, placed in accelerated aging.


We are looking for a highly motivated and creative post-doctoral researcher with proven abilities to solve scientific problems, critically discuss experimental results, and interact with scientists from different backgrounds ( biologists, modelers, biophysicists, computer scientists). Applicants should have practical skills in ecotoxicology and marine biology, with particular emphasis on the coastal environment; knowledge of polymers and micro / nanoplastics and knowledge of aquaculture and shellfish farming would be a plus. Strong expertise in data processing (Statistics on R software) is also required. Excellent writing skills are required (scientific articles and reports in English) and communication skills too.

Work Context

The working time of the position will be allocated 100% to the PLASTIC LAB project. The candidate will join the AMARE team (Responses of Marine Animals to Environmental Variability) of the LIENSs UMR7266 laboratory. The LIENSs laboratory is a mixed interdisciplinary research unit (UMRi 7266 La Rochelle University - CNRS). This laboratory puts interdisciplinarity at the service of the challenges of sustainable development in connection with the coast. The Plastic Lab project aims to better understand the behavior of oyster plastics over time. It will consist of using experimental devices from LIENSs in partnership with the LaSIE laboratory at La Rochelle University: the accelerated aging chamber to simulate the actions of the marine environment on the physico-chemical properties of plastics (UV radiation, salinity, temperature); the experimental littoral mesocosm to simulate tides and currents in order to simultaneously and reproducibly recreate the same coastal environment (simulation of wave and tidal action).

Constraints and risks

A large part of the experimental work will be carried out in the laboratory. Consequently, this project requires a perfect laboratory practices.
