686. The onset of Pliocene – Early Pleistocene fluvial aggradation in the Southeastern Alpine Foreland (Velenje Basin, Slovenia) and its paleoenvironmental implicationsEva Mencin Gale, Petra Jamšek Rupnik, Naki Akçar, Marcus Christl, Christof Vockenhuber, Flavio S. Anselmetti, Andrej Šmuc, 2024, original scientific article Abstract: In this study, we focused on the Pliocene–Early Pleistocene fluvial terraces in the Velenje Basin andreconstructed the morphostratigraphy, sedimentary depositional environment, provenance and age of the graveldeposits using geomorphological, sedimentological, petrographic and chronological analyses. Geomorphologicalmapping revealed the presence of two main river‐terrace groups. The terraces in the older terrace group are severelydegraded and preserved only as remnants capping high ground, while in contrast the younger group is betterpreserved. Detailed lithofacies analyses of four selected stratigraphic sections of the older terrace group show that thegravel was deposited in a meandering and wandering environment. The gravel consists of metamorphic, igneous,volcaniclastic, clastic and carbonate lithologies derived from the north, east and west from the Paka Rivercatchments. To determine the timing of deposition, we performed isochron‐burial dating using cosmogenic 26Al and10 Be. Our new age constraints date the deposition of the older terrace group to 2.7 ± 0.3 Ma. Establishing theaggradation and incision model of the Velenje Basin documents pronounced regional tectonic uplift during thePliocene–Early Pleistocene, which led to incision and the subsequent formation of a terrace staircase.

690. Report on economic justification of the project : LIFE Stop CyanoBloomMaja Zupančič Justin, Gorazd Lakovič, Tinkara Rozina, Bojan Sedmak, Marko Gerl, 2017, final research report Abstract: The Annexe 17 of the Final Report of the project LIFE Stop CyanoBloom, presenting the “Report on economic justification of the project” is composed of 14 chapters. The first part of the report gives a general overview of the cyanobacteria and their blooms, and species and toxicity of cyanobacterial toxins. With a literature review, economic consequences of cyanobacterial blooms on human health, commercial fishery, tourism and recreation, and lake monitoring and management have been evaluated. The chapter on phytoplankton and bacterioplankton monitoring options presents the importance of the phytoplankton for the lake ecology and evaluation of the water quality status. Traditional phytoplankton monitoring approaches are compared to the new monitoring options applied in the project. The chapter in-lake cyanobacterial control options give a broad review of available in-lake rehabilitation and remediation options, which can be compared with the electrochemical oxidation technique presented in the following chapter and applied in the project. According to the results obtained during the pilot testing activities, a cost evaluation of the approach has been performed and presented in the report. The last chapter gathers open issues and proposals for the further work in this field.
Keywords: cyanobacteria, cyanotoxins, health risk
