Emerging organic compounds in European groundwater
B. Lopez, A. Togola, M. E. van Vliet, L. Rosenqvist, Nina Mali, A. Kuczyńska, Anja Koroša, J. Grima-Olmedo, E. J. Crane, D. J. Lapworth, S. Y. Bunting

Abstract: In Europe, emerging organic compounds (EOCs) in groundwater is a growing research area. Prioritisationfor monitoring EOCs in Europe was formalised in 2019 through the development of thefirst voluntarygroundwater watch list (GWWL). Despite this, groundwater occurrence data in the peer reviewedliterature for Europe has not been reviewed to date. Questions surrounding the effect, toxicity, move-ment in the subsurface and unsaturated zone make the process of regulating EOC use difficult. The aim inEurope is to develop a unified strategy for the classification, and prioritisation of EOCs to be monitored ingroundwater. This paper compiles evidence from the recent published studies from across Europe, since2012, when the last major literature global review of EOCs in groundwater took place. A total of 39studies were identified for review based on specific selection criteria (geography, publication date,sample size>10, inclusion of EOCs data). Data on specific compounds, and associated meta-data, arecompiled and reviewed. The two most frequently detected EOCs, carbamazepine and caffeine, occurredin groundwater at concentrations of up to 2.3 and 14.8mg/L, respectively.

UNEXUP: robot-based exploration technology for underground flooded mines
Norbert Zajzon, Balázs Bodó, Luís Lopes, Gorazd Žibret, Márcio Tameirão Pinto

Abstract: UNEXUP is a direct continuation of the UNEXMIN project. In UNEXMIN efforts were made towards the design, development and testing of a robotic exploration technology for underground flooded mines, with navigational and geoscientific instruments. In UNEXUP the main goal is to raise commercial interest and improve the system's hardware, software and capabilities. The UX-1 NEO, to be developed and tested in 2020, will address the limitations detected during UNEXMIN field missions, and will meet the needs and requirements from mining companies, geological surveys and other potential customers. In addition, a new robot will be built and added to the system, to be ready in 2021, which will open further mineral exploration possibilities.

ROBOMINERS - Developing a bio-inspired modular robot-miner for difficult to access mineral deposits
Luís Lopes, Balázs Bodó, Claudio Rossi, Stephen Henley, Gorazd Žibret, Alicja Kot-Niewiadomska, Vitor Correia, 2020

Abstract: Within the ROBOMINERS project an innovative technology for the future exploitation of small and difficult to access mineral deposits is being studied. The project has two main objectives. First, the development of a bioinspired reconfigurable robotic miner prototype, able to navigate, explore and mine selectively with a certain degree of autonomy. The robot-miner will be able to work under different conditions, making the exploitation of many mineral deposits economically feasible, while reducing social and environmental impacts associated with conventional mining methods. The second objective is the creation of a vision of a new mining ecosystem, its function, parts, research roadmaps and visions for years 2030 and 2050, including creation of novel ideas from other sectors, particularly robotics. The robotic ecosystem concept will be tested in representative sites across Europe with simulations, showcasing the different mining environments and conditions where it can be applied.

Towards a holistic approach to the geochemistry of solid inorganicparticles in the urban environment
Martin Gaberšek, Mateja Gosar, 2021

Abstract: Airborne particulate matter (PM) has a major impact on the biogeochemical cycles of chemical elements in theurban environment. Anthropogenic-derived PM emissions are the cause of some of the most severe environmen-tal and health problems. The presented study aims to improve our knowledge of PM dynamics by introducing amulti-media, multi-analytical and multi-elemental holistic approach to geochemical studies of inorganic PM inthe urban environment. The importance of the holistic approach is highlighted and its application in a casestudy of Maribor (Slovenia) is presented. The chemical composition and individual particulate characteristicsof street, attic and household dust were determined and compared with the characteristics of airborne PM,and PM deposited in snow, together with the chemical composition of the soil. We found that the mineralogicaland chemical composition and the individual solid particle characteristics of the studied media differ consider-ably. Nevertheless, minerals of geogenic origin are present in all media. The highest levels of potentially toxic el-ements (PTEs) in all media, except household dust, are typical for industrial areas. Street dust primarily reflectsthe influence of winter road maintenance and industrial activities, while characteristics of household dust arepredominantly influenced by indoor activities and properties of dwellings. The comparison of the chemical com-position of attic and street dust indicates that emissions of As, Cd, Pb, S and Zn were higher in the past. The char-acterisation of airborne PM and PM deposited in snow is essential for the identification of the mostrecentsourcesof PTE-bearing particles. Several industrial sources and the fate of some particle types in the environment havebeen determined based on thefindings of the SEM/EDS analyses. This study confirms that various environmentalmedia are carriers of diverse geochemical information and highlights the importance of a holistic approach ingeochemistry of PM in urban areas.

GPR survey to reveal a possible tectonic tilt of the Brežice Sava River Terrace in the Krško Basin
Marjana Zajc, Marijan Poljak, Andrej Gosar, 2021

Abstract: It has been supposed that the Brežice Sava River Terrace (BSRT) is tectonically disturbed near the town of Brežice and tilted to the north. To confirm this tectonically induced tilt in a quantitative sense, low-frequency Ground Penetration Radar (GPR) was applied. A total of eight GPR profiles were recorded across the BSRT providing information of the lower boundary of the terrace, which consists of loose to poorly cemented Quaternary gravel, while its Tertiary basement consists of poorly cemented carbonaceous silt (marl). The premise of the study was the assumption that this lithological boundary could be detected by the GPR method. In addition to the upper surface of the BSRT being tilted to the north by 0.18°, GPR profiles also showed a 0.04° difference in the tilt between the upper surface of the terrace and its lower boundary with the basement, which we assigned to the sin-sedimentary tilt. Upon this information, a cumulative tectonically induced dip of the BSRT lower boundary was defined at 0.22°.

Nov primerek ribe Protriacanthus gortanii D'Erasmo, 1946 (Protriacanthidae, Tetraodontiformes) iz zgornjekrednih plasti pri Komnu (Slovenija)
Matija Križnar, 2015

Abstract: Okolica Komna na Tržaško-komenski planoti je že dve stoletji znano najdišče krednih vretenčarjev. Med njimi prevladujejo ribe kostnice, ki so posebej pogoste v Komenskem apnencu Povirske formacije. Iz ploščastih apnencev prihaja nova najdba primerka majhne ribe Protriacanthus gortanii, ki je bila prvič opisana ravno iz teh plasti. Riba ima značilno morfologijo z močnimi bodicami plavutnic na hrbtni in trebušni strani. Najdba predstavlja verjetno že deveti raziskani primerek iz stratigrafsko dobro opredeljenega najdišča na Tržaškokomenski planoti.
