Pasvik valley and Sør-Varanger (Nikel and Zapolyarny fallout)
Finnmark, Norway
Soils
- Type
- Soil
Boreal forest exposed for more than 70 years to emissions from the Russian smelters. Sites 4 and 5 (Svanvik) near the smelter, north-east transect to Karpdalen (site 15) downwind, site 6 the farthest to the north-west. Snow and PM10 from January-March 2015, soils, mosses and bedrock from August 2015. Coordinates of Svanvik (site 5).
δ60Ni in ‰ (per mil) Values of the same system
Standard : NIST SRM 986
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| 1.68 ± 0.04 ‰ | 1.65 / 1.71 ‰ | 2 | topsoil (most contaminated layer) Mean and standard deviation recalculated from 2 values. Sites 4 and 5, the most contaminated: clearly heavier than the smelter materials, which the authors attribute to preferential uptake of light nickel by plants and microorganisms in these organic-rich soils. | Šillerová et al.

| 0.79 / 1.12 ‰ | snow, lichens and topsoils Range of most snow, lichen and soil samples, which overlaps the smelter materials; all environmental and bedrock samples: -0.01 to +1.71 ‰. | Šillerová et al. (2017), Stable isotope tracing of Ni and Cu pollution in North-East Norw… | ||
| 0.22 / 0.49 ‰ | bedrock (whole rock) Bedrock, lighter than the surface samples: soil nickel comes mainly from the smelters. | Šillerová et al. (2017), Stable isotope tracing of Ni and Cu pollution in North-East Norw… | ||
| −0.05 / 0.79 ‰ | 4 | PM10 PM10 from Svanvik and Karpdalen, January and March 2015: each filter covers one month and depends on the prevailing wind. | Šillerová et al. (2017), Stable isotope tracing of Ni and Cu pollution in North-East Norw… |

| −1.25 ± 0.24 ‰ | −1.49 / −1.02 ‰ | 3 | topsoil (most contaminated layer) Mean and standard deviation recalculated from 3 values. Sites 4, 5 and 15, those accumulating most copper: the closest to the smelter materials. | Šillerová et al. (2017), Stable isotope tracing of Ni and Cu pollution in North-East Norw… |
| −3.94 ± 0.3 ‰ | 1 | topsoil (most contaminated layer) Site 6, the farthest: close to the bedrock. | Šillerová et al. (2017), Stable isotope tracing of Ni and Cu pollution in North-East Norw… | |
| −3.52 / −3.04 ‰ | bedrock (whole rock) Bedrock, the lightest copper of the study. | Šillerová et al. (2017), Stable isotope tracing of Ni and Cu pollution in North-East Norw… | ||
| −3.05 / −2.42 ‰ | 4 | PM10 PM10, between the smelter materials and the bedrock. | Šillerová et al. (2017), Stable isotope tracing of Ni and Cu pollution in North-East Norw… | |
| −0.35 / −0.06 ‰ | lichens Lichens (Hypogymnia physodes), the heaviest copper: biogeochemical fractionation rather than a distinct source according to the authors. | Šillerová et al. (2017), Stable isotope tracing of Ni and Cu pollution in North-East Norw… | ||
