Description
The aim of the CONTAMPUMP project proposed by a young team of researchers from the M.I.O. is to understand the biological mechanisms of the chemical, metallic and organic contamination at the base of marine food webs in plankton and in pelagic and benthic planktivores. Contaminants were selected from priority substances on the WFD and MSFD lists: trace metals, Hg, MMHg, PAHs, PCBs, pesticides. The project is organized in three thematic tasks: temporal WP1 (a temporal approach during 18 months in the urbanised Bay of Marseille (SOLEMIO station of the RNO SOMLIT network), spatial WP2 (a trans-Mediterranean north-south spatial approach in the western Mediterranean in targeted areas of scientific and economic interest, in connection with the Hippocampus campaign), and WP3 modelling (modelling the transfer of contaminants in the ecosystem of the Gulf of Lions from plankton to consumed ressources, using EwE Ecotracer module with a new software developed for multi-contaminant analyses). The aims of CONTAMPUMP are to answer the following questions: (I) does organism size influence the levels of contamination (bioaccumulation or biodilution)? (II) how does the trophic level influence the contaminant transfer in the planktonic food web (biomagnification or biodiminution)? (III) does food selection influence contaminant concentrations in various planktivorous species? (IV) what is the temporal variation of contaminant concentrations in relation to the plankton composition and the potential sources of contaminants (rivers, urban areas, STEP, port, industries)? (V) are the patterns of contamination of plankton different between contrasted areas? (VI) how does the transfer of contaminants occur from plankton to the fishery resources (trophic modelling)? The size and the variability of the composition of some biological targets require the development of new approaches for sampling and measurement methods, as well as close transdisciplinary work. The complementary skills in chemistry, biochemistry, biology and ecology of the young team will generate links and a scientific dynamic within the M.I.O. and enable answers to be found to these questions of major interest for the sustainable management of Mediterranean ecosystems.
