RESEARCH FIELDS

• Chemistry of aquatic systems (micro-environments), including surface and ground waters, marine surface microlayer and sediments: circulation, chemical behavior, impact on ecosystems and distribution of metals, nutrients and organic pollutants, qualitative characteristics.
• Study of natural systems of particular interest, such as river estuaries, wetlands, lagoons etc, investigation of coastal eutrophication and its impact.
• Study of biogeochemical cycles and metal speciation, nutrients and other substances in aquatic systems
• Environmental impact of anthropogenic activities in the natural environment, phenomena of marine pollution with emphasis on coastal systems.
• Ecotoxicological studies in aquatic ecosystems, bioaccumulation studies in various marine organisms – bioindicators and study of the impact of chemical compounds on the food chain.
• Study of metal speciation in natural systems and foodstuffs, responsible for biological activity and impact. Toxicological study of trace elements in biological fluids.
• Chemistry of the atmospheric environment and indoor spaces, determination of various pollutants in aerosols.
• Magnetic properties of particulate matter and sediments.
• Applications of environmental geochemistry with emphasis on magnetic characterization, behavior and distribution of principal elements and trace metals in soil systems.
• Study of interactions in the rock – water system with emphasis on chromium speciation.
• Environmental management of aquatic and marine ecosystems (use and exploitation of research results), contribution to the establishment of environmental policy and legislation.
• Environmental education with emphasis on sustainable development.
