It is mandatory and important to understand source, flux, distribution and fate of anthropogenic persistent pollutants (POPs) to assess contamination and solutions. Ecotoxicology of legacy, emergent and new POPs is an efficient and essential tool to investigate polar, temperate and tropical ecosystems. Research projects are focused on predators (fish like shark, tuna, swordfish; reptiles as sea turtle; seabirds; marine mammals) and their trophic webs. Special attention is devoted to non‐destructive/nonlethal sampling methods, specially for protected species or in protected areas.
The studied chemicals include legacy, emergent and new POPs as listed by the Stockholm Convention (http://chm.pops.int/Convention/ThePOPs/tabid/673/Default.aspx ).

In this context, the main aims of the research team are:

  • POP levels, their distribution in the body tissues, their patterns of accumulation from tissue to upper levels of an ecosystem;
  • POP transfer between abiotic (air, water, sediment) and biotic compartments (trophic webs) and between trophic levels;
  • assessment of toxic risk (method of TEF, TEQ) in marine trophic webs, using key‐species to evaluate the health status of populations and ecosystems;
  • assessment of the risk for human consumptions in the case of edible and commercial species (e.g. tuna, swordfish, shark, etc) through the calculation of the weekly tolerable intake (TWI) and estimated daily intake (EDI);
  • role of nanoparticles in the POP accumulation in marine organisms (Trojan effect);
  • ecology of marine Antarctic vertebrates (penguins, stercorarids).
