The Environmental Geochemistry Unit carries out researches mainly focused on the abundance, distribution and behaviour of trace elements in the surface environment. The researches concern several environmental matrices such as soil, stream sediment, surface water and groundwater, particulate matter, vegetable and animal organisms, as well as foods.
- Trace elements in the soil-biosphere system: behaviour of trace elements in soil formation; mobility and availability of trace elements in soil and their transfer to biosphere in both uncontaminated and contaminated sites.
- Heavy element contamination: abundance, distribution and behaviour of heavy elements in air, soil, surface water and groundwater, vegetable and animal organisms in urban, industrial, mining and agricultural sites; assessment of air and soil quality using particulate matter and bioindicators such as lichens, earthworms and isopods.
- Water chemistry: chemistry of stream waters and groundwater (major ions and trace elements); influence of human activities on the concentration and distribution of inorganic contaminants in surface waters and groundwater.
- Food chemistry and traceability: inorganic chemical composition of foods such as honey, grapes and wines (macro and micronutrients and non-essential trace elements); relationships between the geochemistry of vineyard soils and the chemical composition of grapes and wines; use of trace elements as geochemical tracers of the geographical origin of foods.
- Geochemical mapping: use of soil and stream sediment based geochemical maps to define the relationships between the distribution of trace elements in the surface environment and the geolithological features of territory, and to locate geochemical anomalies and contaminated areas.
