The Ljubljansko polje aquifer, which is the main supply of drinking water for local population in Ljubljana, Slovenia highly vulnerable to anthropogenic pollution. In this study, geochemistry major constituents including nitrate concentrations and dual isotopes were used ascertain spatial distribution processes sources groundwater from seven wells at three different supplies: Kleče, Hrastje Jarški prod. Ca2+-Mg2+-HCO3- type approaching equilibrium with respect dolomite are moderately...
The microalgae Spirulina may be a popular dietary supplement rich in essential nutrients and vitamins, but oversight of the industry, general, remains limited, increasing incidents adulteration, misbranding, undeclared ingredients together with misleading claims create potential risks. In response, this study characterized elemental, amino acid fatty content commercially available supplements Slovenia using EDXRF, ICP-MS GC-MS compared results their nutritional declaration. gathered data...
This study investigates consumer preference and acceptance of three meat alternatives—plant-based, lab-grown, insect-based—as sustainable choices to meet the demands a growing population evolving food systems. Insights were gathered from European consumers regarding their perceptions consumption patterns using mixed-methods approach. The approach employed questionnaire followed by focus group discussions conducted in Slovenia UK understand motivations barriers behind responses. chosen as...
Coupled measurements of nitrate (NO3−), nitrogen (N), and oxygen (O) isotopic composition (δ15NNO3 δ18ONO3) were used to investigate the sources processes N cycling, while microbial source tracking (MST) method was identify microbiological pollution in surface water Sava River Basin (SRB) autumn 2014 2015 during high low discharge. Atmospheric deposition or nitrate-containing fertilizers found not be significant riverine SRB. The ranges isotope values suggest that NO3− SRB derives from soil...
The gastronomic relevance and price of truffles are related mainly to its unique aroma. In this study, we explore the impact that different volatile compounds have on aroma quality fresh using gas chromatography-mass spectrometry (GC-MS). Four hundred sixty ascocarps nine truffle species (Tuber aestivum, Tuber magnatum, melanosporum, mesentericum, brumale, excavatum, rufum, indicum macrosporum) harvested in 2018/19 2019/2020 from 11 countries (Slovenia, Croatia, Bosnia Herzegovina,...
The authenticity and geographical origin of wines produced in Slovenia were investigated by a combination IRMS SNIF-NMR methods. A total 102 grape samples selected carefully collected three different wine-growing regions 1996, 1997, 1998. stable isotope data evaluated using principal component analysis (PCA) linear discriminant (LDA). isotopic ratios to discriminate between coastal continental are the deuterium/hydrogen ratio methylene site ethanol molecule (D/H)II δ13C values; including...
The authenticity of vegetable oils consumed in Slovenia and Croatia was investigated by carbon isotope analysis the individual fatty acids use gas chromatography-combustion-isotope ratio mass spectrometry (GC/C/IRMS), through bulk oil. from samples olive, pumpkin, sunflower, maize, rape, soybean, sesame were separated alkaline hydrolysis derivatized to methyl esters for chemical characterization capillary chromatography/mass (GC/MS) prior isotopic analysis. Enrichment heavy ((13)C) oil are...
Calcite and dolomite solubilities in open weathering environments are proportional to p CO 2 inversely temperature, solubility is progressively greater than calcite below 25°C. The continent‐scale budget reveals the significance of Northern Hemisphere (NH) globally integrated riverine fluxes Ca 2+ , Mg HCO 3 − . NH contributes 70% global flux while only 54% discharge. We present results a comparative hydrogeochemical study carbonate mineral equilibria two carbonate‐rich river basins. Surface...
Isotope parameters (δ13Choney, δ13Cprotein, δ15N) were determined for 271 honey samples of 7 types (black locust, multifloral, lime, chestnut, forest, spruce, and fir honeys) from 4 natural geographical regions Slovenia. Carbon nitrogen stable isotope ratios measured to elucidate the applicability this method in identification botanical origin adulteration. Only 2.2% adulterated according internal standard carbon ratio analysis method. Botanical did not have any major influence on profiles;...
