The aim of the study is to analyse the carbon isotope dynamics of freshwater tufa precipitated in karstic streams between the spring water and the first significant tufa barrage using field measurements, water chemistry, and carbon isotope analysis. A further aim was to examine the fossil tufa precipitations in recently active areas and their neighbourhood to determine their age using the 14C method. Based on the 3H content the water samples are relatively young (<10 y). To calibrate the calendar age of older tufas, dead carbon proportion (dcp) were determined in the recently formed freshwater tufas. The lowest dcp of the recent freshwater tufas was estimated at Sebesvíz (9.6±1.3%), the highest at Szalajka (16.4±2.4%) and a moderate value at Dobrica Spring (13.8±2.2%). Due to the rapid decrease in atmospheric 14C level we have to compensate the atmospheric 14C drop between the water infiltration time and the deposition time of fresh carbonates to compensate the bomb-effect. The oldest fossil tufa age (BC 6421-6096) was found at Sebesvíz located around 20 metres away from the riverbed, while the youngest fossil tufa ages (a few years/decades old) were found in the recently active area at all sites.}, year = {2023}, eissn = {2060-467X}, pages = {55-71}, orcid-numbers = {Kele, Sándor/0000-0002-8607-7636} } @article{MTMT:34040462, title = {Phytoremediation, recovery and toxic effects of ionic gadolinium using the free-floating plant Lemna gibba}, url = {https://m2.mtmt.hu/api/publication/34040462}, author = {Szabó, Sándor and Zavanyi, Györgyi and Koleszár, Gergő and del Castillo, Dahlia and Oláh, Viktor and Braun, Mihály}, doi = {10.1016/j.jhazmat.2023.131930}, journal-iso = {J HAZARD MATER}, journal = {JOURNAL OF HAZARDOUS MATERIALS}, volume = {458}, unique-id = {34040462}, issn = {0304-3894}, year = {2023}, eissn = {1873-3336}, orcid-numbers = {del Castillo, Dahlia/0000-0001-6445-7841; Oláh, Viktor/0000-0001-5410-5914} } @CONFERENCE{MTMT:33938841, title = {New evidence of Bronze Age glass trade: Blue glass beads from the Tumulus culture cemetery of Maklár (NE Hungary)}, url = {https://m2.mtmt.hu/api/publication/33938841}, author = {Mengyán, Ákos and Hrabák, Zita and Sztankovánszkiné Osváth, Zsófia and Bajnóczi, Bernadett and Braun, Mihály and Paja, László}, booktitle = {Scales of Social, Environmental & Cultural Change in Past Societies}, unique-id = {33938841}, year = {2023}, pages = {10-11}, orcid-numbers = {Mengyán, Ákos/0000-0002-8946-7023; Hrabák, Zita/0009-0002-8583-8808; Bajnóczi, Bernadett/0000-0003-0006-7611; Paja, László/0000-0002-0066-3838} } @article{MTMT:33892864, title = {The role of fire disturbances, human activities and climate change for long-term forest dynamics in upper-montane forests of the central Dinaric Alps}, url = {https://m2.mtmt.hu/api/publication/33892864}, author = {Cagliero, Eleonora and Paradis, Laure and Marchi, Niccolo and Lisztes-Szabó, Zsuzsa and Braun, Mihály and Hubay, Katalin and Sabatier, Pierre and Curovic, Milic and Spalevic, Velibor and Motta, Renzo and Lingua, Emanuele and Finsinger, Walter}, doi = {10.1177/09596836231163515}, journal-iso = {HOLOCENE}, journal = {HOLOCENE}, volume = {33}, unique-id = {33892864}, issn = {0959-6836}, abstract = {We present the first high-resolution Holocene pollen, plant-macrofossil, and charcoal records from the upper-montane zone in the central Dinaric Alps. Drawing on these new records from well-dated lacustrine sediments of Zminje Jezero (ca. 1500 m a.s.l.; Montenegro) and on independent chironomid-inferred summer temperatures, we explore long-term ecosystem responses to variations in climate, fire disturbances and land use, as well as legacy effects of past environmental changes. A mixed spruce-fir forest established in the upper-montane zone around 9500 cal BP, and Fagus sylvatica became co-dominant with the two conifers after 5000 cal BP. Prehistoric land-use pressure was overall remarkably low, but increased since 2000 cal BP and was highest after the Middle Ages. We found a significant positive relationship between biomass burning and summer temperature, indicating that fires were mostly climate driven. Picea abies was insensitive to summer temperature, biomass burning and human impact, which supports the view that spruce forests may not be significantly impacted by fire. In contrast, Abies alba and other disturbance-sensitive trees (Tilia, Ulmus, Fraxinus excelsior-type) show significant negative responses to land-use pressure and positive responses to summer temperature. This supports the notion that these species may be well-adapted to warmer-than present summer temperatures and that their populations declined in recent millennia due to land-use activities. Conversely, F. sylvatica was sensitive to summer temperatures but was promoted by low biomass burning, indicating that its expansion in the spruce-fir dominated forest was enhanced by the onset of cooler and possibly also moister climatic conditions as well as by fire disturbances.}, keywords = {Holocene; vegetation dynamics; Mountain forests; MONTENEGRO; Fire history; vegetation-fire interactions}, year = {2023}, eissn = {1477-0911}, pages = {827-841}, orcid-numbers = {Lisztes-Szabó, Zsuzsa/0000-0002-6322-8542; Sabatier, Pierre/0000-0002-9620-1514; Curovic, Milic/0000-0002-5033-758X; Finsinger, Walter/0000-0002-8297-0574} } @{MTMT:33746530, title = {A Szent Anna-kráter tavi-lápi fejlődéstörténete}, url = {https://m2.mtmt.hu/api/publication/33746530}, author = {Buczkó, Krisztina and Máthé, István and Jakab, Gusztáv and Tóth, Mónika and Braun, Mihály and Korponai, János and Ács, Éva and Karátson, Dávid and Magyari, Enikő Katalin}, booktitle = {A Kárpátok legfiatalabb tűzhányója, a Csomád.

They pass through wastewater treatment plants (WWTPs) unhindered escaping degradation. Although GBCAs are subjects of intensive research, we recognized that a quantitative approach to the mass balance of gadolinium, based on known input and output data, is missing. The administered amount of Gd as GBCAs, the number of out- and inpatients and the concentration of rare earth elements (REEs) in wastewater were monitored for 45 days in a medium sized city (ca. 203,000 inhabitants) with two MRI centres. An advection-dispersion type model was established to describe the transport of Gd in the wastewater system. The model calculates with patient locality, excretion kinetics of Gd and the yield of wastewater. The estimated and measured daily amount of anthropogenic gadolinium released to the WWTP were compared. GBCAs (Omniscan and Dotarem) were administered to 1008 patients representing a total of 700 ± 1 g Gd. The amount of total Gd entering the WWTP was 531 ± 2 g, of which the anthropogenic contribution (i.e. GBCAs) was 261 ± 6 g (49 ± 1 % of the total Gd) during the sampling campaign. Local residents and inpatients should fully release Gd in the city, but outpatients only partially. Overall, 37 ± 1 % of the total administered Gd was recovered in the wastewater, so the remaining 63 ± 1 % of administered Gd is expected to be dispensed outside of the sewer system.

This can provide novel findings in research on environmental change as phytoliths play an important role in the silicon biogeochemical cycle. In favorable environmental conditions, Picea abies [L.] H. Karst (Norway spruce) needles develop a phytolith layer consisting of more or less cubical or cuboid (blocky) phytoliths in their transfusion tissue that becomes continuous toward the apex of the needle. This can be studied in situ in fossil (subfossil) needles under a stereomicroscope. This study reports the blocky-type phytolith preservation in fossil spruce needles in sediment sections of the lake Černé jezero (Bohemian Forest, Czech Republic). The oldest needle containing phytoliths was 7.8 cal ka BP. Despite differences in the Energy Dispersive X-ray (EDX) spectra of different age phytoliths, the studied subfossil phytoliths did not lose their globular ultrastructure in the needle tissue, proving the stability of this phytolith morphotype. As the tissue of the needle fossils can preserve phytoliths in situ, further micro-analytical measurements will make these needles promising tools for paleoenvironmental reconstructions. The most favorable period for spruce phytolith formation for the studied region appears to be the period 6.0–4.5 cal ka BP, within the Holocene Climate Optimum period. In order to use these phytoliths as a terrestrial climate proxy, the next step is to refine their sensitivity to environmental changes.}, year = {2023}, eissn = {1477-0911}, pages = {471-477}, orcid-numbers = {Lisztes-Szabó, Zsuzsa/0000-0002-6322-8542; Csík, Attila/0000-0002-8173-9653; Kuneš, Petr/0000-0001-9605-8204} }
