The course provides a basic preparation for the understanding of the main geochemical and biogeochemical processes underlying the mechanisms of partition of the chemical elements in natural materials.
Students acquire knowledge to manage geochemical and biogeochemical data (R and Matlab software) in a correct way, validate their correctness for an analytical point of view and to construct conceptual models able to describe the investigated phenomena (natural or anthropic) in a critical way.
Students acquire the skills to evaluate and quantify the behaviur of chemical elements in different natural frameworks with the final aim to understand the partition processes among different geological matrices and natural reservoirs.
