People

• Biogeochemical cycling of trace metals in the soil-plant-water system
• Source, speciation and mobility of heavy metals organic pollutants in soils and sediments
• Non traditional stable isotopes (e.g. Cu, Zn) as tracers for biogeochemical cycling and anthropogenic contamination
• Biogeochemical processes in small inland water bodies on the transition of the aquatic-terrestrial domains
