The C-BASS project aims at acquiring advanced knowledge on the interactive impacts of chemical contaminants and increased temperature on a model species of high ecological relevance and economic importance, the European sea bass (Dicentrarchus labrax). Marine ecosystems are foreseen to be impacted by global warming as a consequence of climate change and by the ever-increasing number of persistent and bioaccumulative contaminants such as per- and polyfluoroalkyl substances (PFASs). Together, these stressors challenge marine organisms and may be detrimental to their growth and development.

C-BASS objectives are to answer: (1) how temperature increase could influence the toxicokinetics of PFASs (assimilation rates and efficiencies, metabolisation), and (2) how these combined stressors impact the physiological functions (i.e. the gonadotropic and thyrotropic axis) of a temperate climate fish.

Laboratory exposures of sea bass early-life stages under a temperature scenario projected by IPCC for 2100 will be implemented, with dietary contamination of an environmentally-relevant mixture of PFASs.

C-BASS will provide knowledge and tools for a better anticipation and understanding of the coming Global Change and serve as a reference for future studies in marine exposomics and ecotoxicology, in particular in the context of the UN Ocean Decade.

C-BASS research activities are closely linked to the SEAwise project.
