Tracing mercury in the wider Idrija region using stable isotopes
Mercury, a toxic element, known for its physical and chemical properties, spreads throughout the environment and is found in various ecosystems, including water, air, soil, and biological systems. The natural mercury cycle begins beneath the earth's crust, where it rises to the surface and is released into the air through …
Metrology of mercury measurements in the air
Atmospheric mercury (Hg) plays an important role in the biogeochemical Hg cycle. Hg species in the atmosphere are present in very low concentrations. While gaseous elemental mercury (GEM) is relatively inert, gaseous oxidized (GOM) and particulate-bound (PBM) mercury are highly reactive. These characteristics of atmospheric Hg species make the speciation …
Authenticity and traceability of food and food flavourings using a stable isotope approach
Food fraud or economically motivated adulteration has been an issue throughout history. Even today, it remains a significant and growing problem, driven by globalisation, economic opportunity and the low probability and severity of punishment. Fraud is a concern for food producers, consumers, regulatory agencies and scientific organisations, and food fraud …
CO2 dynamics in a river system: mass balance, hydrological, geochemical and biochemical impacts
A 3-year systematic investigation (2007–2010) of water chemistry using conventional and stable isotope tracers helped us delineate hydro-biogeochemical processes in the karstic Krka River watershed. By mineralogical and stable isotopic examination of tufa deposits and combining the results with water chemistry, we were able to evaluate the suitability of tufa …
