Abstract The aim of this study was to evaluate the cytotoxic and genotoxic potential of the wastewater (WW), the effectiveness of the treatment used by the wastewater treatment plant (WWTP) with ...sequential batch reactors (SBR) technology, and whether its final treated effluent (FTE) can compromise the water quality of the river at the location where it is discharged. We focused our research on six examples. For analytical chemistry and Allium metaphase (M) test all six samples were collected. Of these, three are so-called biotechnological patterns (WW, WW after mechanical step treatment and FTE), and three are natural riverine environmental patterns. For the micronucleus (MN) test, fish specimens were collected from three sites in the river Kamniška Bistrica. The first two sites locations are up and down the FTE outlet. Results from these areas were compared to the third site (not polluted) reference site, the so-called natural control group. Complementary study with analytical chemistry and biological tests shows that the treatment effect SBR in the Domžale–Kamnik central WWTP carried effectively proved to be efficient for the removal of the cytogenotoxic substances in treated effluent and consequently in aquatic environment.
Nine archaeological bituminous potsherds from the Neolithic of Maliq and Kamnik (5000–4500 BCE) in Albania were geochemically compared for the first time to four natural asphalts from the famous ...present-day mine of Selenicë. The bitumen on potsherds originates from Selenicë, a unique source in Albania and the southern Balkans. Carbon isotopes on the asphaltene chromatographic fraction confirm that the bitumen on the potsherds came from Selenicë. Carbon and hydrogen isotopes on saturates, aromatics, NSO, and asphaltenes show changes that may be due to biodegradation-oxidation effects and also the occurrence of organic remains from the content of the vessels mixed with bitumens. Steranes, terpanes, and aromatics confirm the increased biodegradation of bitumen on potsherds when compared to natural asphalts references.
In the Kamnik-Savinja Alps (Slovenia), the Lower Serla Dolomite laterally passes into a succession of thin- to medium-bedded bituminous limestones of the Velika planina member. The finely laminated ...lower part of this member contains well-preserved actinopterygian fish and sauropterygian remains. The research aimed to determine the sedimentological and palaeoenvironmental characteristics of the depositional basin on the basis of three detailed sedimentological sections logged atop the Velika planina plateau. The Velika planina member is underlain by a whitish to light grey, thick bedded to massive dolomite with oncoids, stromatolites, and lumachellas deposited under peritidal to shallow subtidal conditions. The lower part of the Velika planina member consists of thin, often platy, finely laminated beds of bituminous mudstone. The Chondrites ichnofossil is very common; however, in some beds numerous lingulid brachiopods, bivalves, and crinoids were observed. Fossil vertebrates and crustaceans are relatively rare and confined to a few levels. Ammonoids are very rare. Subordinate beds of intraclastic-peloid wackestone to packstone, intraclastic-bioclastic grainstone, and bivalve floatstone occur. Slumps are common. Upwards, bedding gradually becomes thicker and bioturbation more common. Finally, stromatolites, birdseye fenestrae, and oncoids reappear. The entire succession is confined to the early to middle Anisian by the foraminifer Citaella dinarica (KOCHANSKY-DEVIDÉ & PANTIĆ). The absence of breccias at the base of the Velika planina member, the gradual transition upwards into shallow marine carbonates, as well as the presence of sauropterygians of the order Nothosauroidea suggest deposition in a relatively shallow basin. The finely laminated facies of the lower part of the member indicates a stratified water column, with oxygenated near-surface waters and hypoxic to anoxic conditions near the sea floor.
Horseshoe crabs are an archetypal chelicerate group with a fossil record extending back to Early Ordovician time. Although extensively studied, the group generally has a low diversity across the ...Phanerozoic Eonothem. Here, we expand the known diversity of true horseshoe crabs (Xiphosurida) by the description of a new taxon from the Middle Triassic Strelovec Formation of the Slovenian Alps. The mostly complete fossil is preserved as an external mould and assigned to the family Limulidae Zittel, 1881 as Sloveniolimulus rudkini, n. gen., n. sp. The use of landmark and semilandmark geometric morphometrics is explored to corroborate the systematic palaeontology and suggests that the new genus and species are valid. We also provide the first quantitative evidence for the extensive diversity of Triassic horseshoe crabs. We suggest that Triassic horseshoe crabs likely filled many ecological niches left vacant after the end-Permian extinction.
Članek obravnava metodološke probleme vrednotenja geodiverzitete na primeru Krajinskega parka Logarska dolina. V njem sta predstavljeni in primerjani dve delno avtomatizirani metodi vrednotenja: prva ...združuje prostorsko odvisnost števila geomorfoloških in hidroloških elementov geodiverzitete s podatki o hrapavosti površja, druga pa upošteva tudi litološko sestavo. Indeksi geodiverzitete so bili izračunani z velikostjo rastrskih kvadratov 50 × 50 m z namenom primerjav in ugotavljanja posplošitev na preučevanem območju. Ugotovljeno je bilo, da vključitev litoloških elementov ni smiselna, če je litologija v vrednotenje že vključena preko geomorfoloških elementov, če z množenjem le poveča vrednost območij z visokim indeksom hrapavosti ali če so si tipi litoloških enot glede na značilnosti podobni.
Caves are important markers of surface evolution, since they are, as a general rule, linked with ancient valley bottoms by their springs. However, caves can only be dated indirectly by means of the ...sediments they contain. If the sediment is older than common dating methods, one has to use multiple dating approaches in order to get meaningful results. U/Th dating, palaeomagnetic analysis of flowstone and sediment profiles, cosmogenic dating of quartz pebbles, and mammalian dating allowed a robust estimate of speleogenesis, sediment deposition, climatic change at the surface, and uplift history on the Periadriatic fault line during the Plio-Pleistocene. Our dates indicate that Snežna jama was formed in the (Upper) Miocene, received its sedimentary deposits during the Pliocene in a rather low-lying, hilly landscape, and became inactive due to uplift along the Periadriatic and Sava faults and climatic changes at the beginning of the Quaternary. Although it is only a single cave, the information contained within it makes it an important site of the Southern Alps.
•We present a comprehensive dating approach to sediments of a Slovenian cave.•We interpret the results in the light of climatic change and tectonic uplift.•We show that collaborative work on one single cave can yield results of broader interest.
Debris floods can cause large economic damage and endanger human lives. This paper presents an extreme May 2018 debris flood that occurred in northern Slovenia near the Krvavec ski resort and caused ...large economic damage. The debris flood was initiated by an extreme rainfall event with a return period of over 50 years. There were large differences in the measured rainfall amounts using different equipment. The estimated volume of the debris material during the event was 4000 m

for the Brezovški graben. In order to mitigate the risk due to future debris flood and debris flow events, a check is planned to be constructed. The part of the design process is presented in this paper. Additionally, RAMMS model was used to validate the empirical equations that were used in the process of the check dam stability design. The model was calibrated using information about the deposition area. Two adjacent torrents were modelled, and we were not able to find a common RAMMS parameter set that would yield adequate simulation performance in both cases.
