The aim of the proposed project entitled "Transport and Chemodynamics of Trace Elements in Freshwater and Coastal Sedimentary Systems" (TRACESS) is to increase our understanding of the biogeochemical cycles that are important for freshwater and coastal sedimentary systems in karstic areas, using specific groups of elements i.e. anthropogenic and bioactive (Cd, Co, Cr, Cu, Mn, Ni, V, Zn), rare earth elements (REE), redox sensitive elements, toxic elements and compounds (organotin compounds) which were chosen to represent different biogeochemical environments where a suite of geochemical processes can be traced. Sideline research will involve balneochemical investigations of peloid producing environments in pristine and anthropogenically impacted locations along the eastern Adriatic coast.
