Learning outcomes
The student will aquire knowledge of the factros controlling the
dispersion of chemical elements in the surface environment and in
different environmental matrices (soil, sediment, water, gases).
the student knows the how to conduct sampling and analysis and is
able to describe and interpret geochemical data. in particular the
student will be able to: plan and execute sampling of different
environmental matrices; elaborate and present the data, using
statistical and cartographic tools; suggest solution to remediate
contaminated situations.
Course contents
Recall of some geochemical principles, with attention to low temperature geochemistry (weathering processe, redox state of the environment, properties of solid particles). Sampling strategy. suitable matrices in enviromentally-oriented geochemical studies. Atmosphere, Hydrosphere (rain, surface water, groundwater). Solid matrices (soils, stream sediments, alluvial sediments, lacustrine sediments). Biological matrices (vegetation, animals). availability and bioavailability: selective and sequential chemical extraction. Data handling: geochemical anomaly definition and identification. Natural background: definition and estimation. Geochemical barrier: definition, types and examples. Systematic geochemistry: description of the properties and geochemical charatcters of some environmentally important chemical elements (As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb, PGE, Se, Sb, Sb, Tl, U, Zn). Interaction with the biosphere: dose-response relation in toxicological studies.
