Tracing origin of food using stable isotopes of light and heavier elements
This dissertation examines two main topics. The first topic is focused on the potential of strontium (Sr) isotope analysis to characterise milk and truffles as selected food commodities, traditionally important for Slovenia. The 87Sr/86Sr ratio for determining the provenance of bovine milk and truffles originating from different regions of Slovenia …
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 …
Overall measurement uncertainty assessment of the k0-based neutron activation analysis
Neutron activation analysis (NAA) is an analytical method used for determination of the elemental mass fractions in different samples. It is based on the measurement of characteristic radiation, usually γ-rays, emitted from radionuclides formed through the process of neutron irradiation of the target element. The k0-NAA method is an NAA …
