Abstract<\/strong><\/h4>

It is essential to characterise the planktonic compartment in its entirety in order to understand its organisation, how it functions and its influence on the trophic transfer of contaminants. This study was carried out in the Bay of Toulon, a model of anthropised ecosystems, and was based on two distinct approaches carried out in parallel. The first involved characterising the structure and dynamics of the planktonic continuum. The second studied its trophic organisation and its influence on THg transfers. The originality of this study lies in the detailed taxonomic characterisation of the planktonic material collected by horizontal net lines and separated into size classes. The use of PFTs enabled us to propose a functional organisation of the planktonic compartment and to gain a better understanding of the mechanisms involved in Hg transfers. The integration of THg into planktonic food webs was mainly due to adsorption phenomena at the surface of the smallest fractions made up of phytoplankton PFTs; whereas for the largest fractions, made up of zooplankton PFTs, Hg transfers seemed to depend more on trophic relationships and feeding strategies specific to the PFTs.<\/p>
