Hana Šillerová et al. recently published a paper focused on the use of Ni and Cu isotopes for tracing contamination sources in the environment. Various environmental samples (snow, soil, lichens, PM10) were collected in north-east Norway to identify the smelter-derived particles and stable isotope fractionation. Based metal isotope fingerprinting, the whole area is enriched in heavy Ni and Cu isotopes highlighting the impact of the smelting activity.
