“…During the last four decades, the migration and surface discharge of deep‐mantle volatiles has been verified in many crustal segments, including western‐central Europe (e.g., Brauer et al., 2013; Carreira et al., 2009; Mamyrin & Tolstikhin, 1984; Minissale, 2000). New efforts are currently undertaken to extend such studies in central‐eastern Europe, in the attempt to (a) understand natural degassing in active tectonic regions (e.g., Etiope et al., 2003, 2004; Frunzeti, 2013; Ionescu et al., 2017; Italiano et al., 2017; Kis et al., 2017; Sarbu et al., 2018; Vaselli et al., 2002), (b) investigate the possible presence of magma at depth below “quiescent” volcanoes (e.g., Kis et al., 2019), and (c) assess the role of fluids in seismogenetic processes (e.g., Baciu et al., 2007; Bräuer et al., 2004, 2005, 2008). Large‐scale outgassing of mantle‐derived fluids has been recognized in different European volcanic regions that last erupted thousands of years ago (e.g., Eger rift, Czech Republic; Eifel, Germany; Carpathians, Romania; Pannonian basin; Aeschbach‐Hertig et al., 1996; Ballentine et al., 1991; Bräuer et al., 2013, 2016; Kis et al., 2017, 2019; Palcsu et al., 2014; Sherwood Lollar et al., 1997; Szöcs et al., 2013).…”

“…11,500–9090 cal yr BP), decreasing water depth and Sphagnum -indicated decreasing pH could be the most relevant environmental changes that may have affected chironomid assemblage change, and led to unusual inferred temperature values in this section of the record. This interpretation is also supported by the fact that diffuse CO 2 emissions continue from the crater at present (Frunzeti and Baciu, 2012). We cannot exclude that the Early Holocene acidic environment was linked to intensified CO 2 upwellings that, via dissolution, contributed to acidification of the lake.…”

Limnological changes and chironomid-inferred summer air temperature from the Late Pleniglacial to the Early Holocene in the East Carpathians

Here we provide the first chironomid record and associated summer air-temperature (TVII) reconstruction between ca. 16,800–9100 cal yr BP from Lake Saint Anne (SZA), situated in the Eastern Carpathians. SZA was formed by the youngest volcanic eruption of Ciomadul volcano at ca. 29,600 cal yr BP. Our main goals in this study are to test whether warming after Heinrich event 1 (H1; ca. 16,200 cal yr BP) had similar amplitude to the late glacial warming, while Younger Dryas (YD) summers remained relatively warm in this region of Europe. We found the most remarkable chironomid assemblage change with a TVII increase of ~3.5–3.8°C at ca. 16,350 cal yr BP at SZA, followed by another slight TVII increase of ~0.8–1.0°C at ca. 14,450 cal yr BP. Only very minor temperature variations were recorded between 14,450 cal yr BP and 11,700 cal yr BP, with an unexpected TVII decrease in the Early Holocene. Variations in water depth together with increasing analogue problems and paludification from ca. 14,200 cal yr BP onwards may have influenced the reliability of our paleotemperature record obtained from SZA. In addition, Sphagnum-indicated decreasing pH, and hence decreasing nutrient level, likely overrode the effect of summer air-temperature changes during the Early Holocene, and this may explain the bias in the chironomid-inferred summer air-temperature reconstruction in the Early Holocene section.

“…The best available techniques are focused on issues relating to the environment associated with the intensive rearing of poultry and swine and the priority are the emissions of ammonia (NH 3 ), also emissions of N and P in soil and water (groundwater or surface) (Proorocu, 2008). as landfills, soil, volcanoes and the method is widely described in the literature (Padron et al, 2008;Frunzeti and Baciu, 2012). The authors applied this method for the solid manure as a new and easy possibility to measure the GHG emissions from livestock.…”

Animal manure is an important source of anthropogenic GHG (greenhouse gas): methane (CH 4 ), nitrous oxide (N 2 O) and carbon dioxide (CO 2 ). The livestock contributes with 37% of global CH 4 emission. The sources of GHG (CO 2 and CH 4 ) are the liquid manure or slurry storage and the compact solid manure. Measurement systems of GHG emission are important for the selection of the appropriate technology. By using the closed chamber method for soil, landfills, volcanoes etc., the present study evaluates the estimation of total emissions of methane and carbon dioxide from an experimental farm in Cluj County, Romania. The investigated area covered with sheep solid manure was about 579 m 2 and ~5 cm thick, for cattle was about 12 m 2 and 5 m thick and for swine was about 1.5 m 5 and 0.5 m thick. The total methane emission measured for sheep manure was 0.83 t CH 4 /year and for cattle manure was 0.185 t CH 4 / year. The total carbon dioxide emission measured for sheep manure was 61.3 t CO 2 /year and for cattle manure was 4.7 t CO 2 /year. The measurement for pigs manure was high and this could be due to the freshness of the manure. The estimated emissions showed that a considerable amount of CH 4 and CO 2 is produced also by an experimental farm and an appropriate management of manure is important for reducing greenhouse gas. In this respect, we believe that the future solution for a green economy is to use manure in biogas plants.
