Ika Paul-Pont, CNRS Bronze medal 2019

With her colleagues from the PANORAMA team, and especially Arnaud HUVET, Ifremer researcher at LEMAR, their work on micro and nano-plastics is among the most cited in our laboratory.

Visit her page on Google Scholar.

See here her personnal page on our site to access her current projects, and click here to read her interview ‘in French) in IUEM’s letter of April 2019.

In 2018 her work was the subject of an article in Sciences-Ouest (in French also), in a special report on microplastics :

GDR “Polymers and Oceans”

GDR-plolymeres et Ocean

The environmental issues related to the presence of plastics are now unanimously recognized. The national (governments) and international (European Union, United Nations) institutions have taken action to better understand the consequences of the presence of these plastic debris in the environment and to try to reduce their releases

The mission of the GDR “Polymers and Oceans”, recently created under the aegis of the CNRS, is to federate the French scientific community (composed by chemists, physicists, biologists, ecologists, ecotoxicologists, oceanographers, economists and sociologists) working on the fate of plastics in the environment to support the emergence of multi-scale and new interdisciplinary research.

The main objectives of this GDR are:

  • to define the main scientific questions and methodological obstacles around this topic;
  • to structure very diverse scientific communities and facilitate the establishment of scientific and technical collaborations between disciplinary fields to support multidisciplinary approaches that are essential to meet the challenges of this topic;
  • to promote collaboration between academic research and industrial research/innovation in relation to competitiveness clusters (e.g. Brittany-Atlantic and Mediterranean MER Poles, IAR) and learned societies (e.g. SFP, SCF, GFP) ;
  • play an active role in the implementation of new experimental protocols to assess the fate of polymers in the aquatic environment ;
  • create an information exchange platform offering an open window to respond to the many requests from economic actors, the media, NGOs and politicians and influence institutional prospects ;
  • participate in the dissemination of scientific knowledge acquired through the organization of an annual national conference and thematic schools.

Ika Paul-Pont and Arnaud Huvet are involved in the scientific council of this GDR.

Responses to emerging pollutants and multi-stress

, ,

LEMAR has a strong research potential in ecotoxicology, within the Brest area, in the framework of collaborations supported with CEDRE and ANSES, and at the national level, with its active participation in the Network in Aquatic Ecotoxicology, and its animation of the GDR PHYCOTOX. We will therefore clearly develop our approaches in ecotoxicology, considering the impact on marine organisms of emerging pollutants (micro and nano plastics), toxic micro-algae, but also the effects of diffuse pollution and multi-stress (chemical stress , thermal, hypoxic) on natural populations in coastal areas. Our approach aims to integrate the new “omics” approaches into ecotoxicology, with the bioenergetics and fitness of organisms. We thus fully subscribe to the exploration of the response of populations to multi-stress, within the conceptual framework of “energy-limited stress tolerance”. (Sokolova et al 2012, 2013). Other works at the interface between ecology, fishery resources and health are developing through the study of the accumulation of heavy metals in organisms.
