About me

 

My research interests focus on the understanding of biogeochemical processes controlling the fate of pollutants, trace-metal speciation, and the identification of contamination sources using geochemical tracers (e.g., by stable isotope ratios). Currently, I am investigating the processes influencing the mobility and the transformations of mercury (Hg), lead (Pb) and cadmium (Cd) along land- to sea transects.

I am particularly interested in Hg biogeochemistry, primarily investigating (i) Hg species mobility, transformations and fluxes (i.e., quantification), (ii) the formation and degradation of methylated Hg species and, (iii) identification of sources of Hg pollution and pathways.

The occurrence of sulfur and iron species, natural organic matter (NOM, dissolved and particulate) and microbial communities strongly influence the interactions and further transformations of Hg species (e.g., biomagnification of methylmercury and its trophic transfer). Investigating the influence of those interactions, as well as the dynamics of transport on particulate-bound Hg is crucial to clarify transformations onsite and far from the Hg source of pollution. I have a special interest in investigating near-coastal environments, tropical and subtropical wetlands and, aquatic systems impacted by small-scale gold mining and other mining -and industrial- activities.
