Comparison of sediments in the Blue Flag Adriatic marinas in 15 years period
Zagreb, Croatia

Dr.sc. Jasmina Obhođaš was born on December 12, 1974. She has been working at the Ruđer Bošković Institute (RBI), Zagreb, Croatia, at the Experimental Physics Department since 2001. She established Laboratory for Nuclear Analytical Methods with her group in 2009. Her research specializations are atomic and nuclear techniques development, neutron activation, trace element analysis, x-ray fluorescence analysis, and data analysis. In last 10 years, the main scientific achievements of her team have been: (i) development of fast neutron activation method for inspection of ship containers; (ii) development of neutron sensor for underwater in-situ chemical characterization; (iii) development of an underwater remotely operated vehicle (ROV) to carry the neutron and additional sensors for chemical analysis and positioning; and (iv) «Atlas of sediments: Croatia’s coastal region and islands». More than 700 surface sediment samples have been collected, analyzed on K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Br, Rb, Sr, Y, and Pb by using EDXRF and results have been presented in the Atlas. The Atlas also discusses the origin of elements, their natural distributions, and anthropogenic contribution as well as their influence on public health. The Atlas aims to provide high quality, multi-purpose environmental baseline data for the Eastern Adriatic, but also the global community dedicated to the sustainable development.

Currently, she is the Lead Project Coordinator of the IAEA project “Enhancing Coastal Management in the Mediterranean, the Black Sea, the Caspian Sea, and the Aral Sea by Using Nuclear Analytical Techniques” (2018-2023). The project aims to collect sediment cores in closed and semi-closed EU seas to evaluate recent historical temperature variations and the fate of carbon in sediments, thus enabling carbon storage assessment and evaluation of positive and negative synergies between pollution loading and the potential of sediments to sequester carbon. By the recognition of spatial patterns and temporal trends in pollutant levels and isotope ratios in environmental archives such are sediments, the future predictions of changes in marine processes and adaptation measures may be proposed.
