Contamination of natural waters by metals constitutes a major threat to our environment.

Adequate environmental management requires rigorous risk assessment practices, which in turn require sound scientific tools and knowledge. Within this context, our research integrates biogeochemistry, physiology and toxicology into a comprehensive framework aimed at unravelling the processes controlling the interactions of metals with aquatic organisms, at the molecular, organismal and ecosystem levels.

This work is carried out on freshwater and marine organisms of diverse trophic levels (including phytoplankton, crustaceans and fish) in temperate and tropical (e.g. Brazil) regions.

Currently, we focus on three research themes:

  1. Characterizing metal speciation/bioavailability in natural waters
  2. Investigating the factors affecting metal bioaccumulation and toxicity
  3. Exploring metal biological fate

The characterization of the effects of environmental conditions (e.g. salinity, temperature, pH) on metal bioaccumulation and toxicity in aquatic organisms is one of our main research focus.
