    Notes: Abstract Terrestrial moss and humus (the O-horizon) are often used separately for determining and monitoring airborne heavy metal pollution. Here, we directly compare the results of analyses of moss and humus samples taken at a density of one site per 300 km2 in a 12 000 km2 area (45 samples) around the nickel smelter in Nikel, the nickel ore roasting plant in Zapoljarnij, both in Russia, and the iron ore mine and mill near Kirkenes in Norway. The samples were air dried, digested in conc. HNO3 and analysed for more than 30 elements by ICP-MS and ICP-AES at the laboratory of the Geological Survey of Finland (GTK). For most elements, observed levels and variations are considerably greater in soil than in moss. The main contaminants, Ni and Cu, reach equally high median levels in the moss and soil, but maximum values are far higher in soil. Both media show comparable regional distribution patterns for the heavy metals, but not for sulphur. Cu and Ni can be used to delineate the limits of contamination in the survey area. Both media show the same picture, with a generally very steep gradient from east to west and background levels being reached 30–50 km from the nickel smelter. When moss is used, Cu/Ni, Cu/S and Ni/S ratios can be used to separate input from the smelting and roasting processes in Russia. Both media are well suited to use separately to detect airborne pollution in this heavily contaminated area. The moss data are generally easier to interpret, but moss is not available at the most polluted sites. Levels for many elements other than Cu and Ni are close to the detection levels in moss samples, but not in humus samples. Information gathered from both media thus complement each other in a regional multi-element survey.

    Ecogeochemical investigation, Kola peninsula: Sulphur and trace element content in snow (1995)
    Springer

    Notes: Abstract The Central Kola Expedition and the Geological Surveys of Norway and Finland have undertaken a multi-media investigation of eight catchments situated in Russia (Zapoljarniy, Monchegorsk, Kirovsk, Kurka), Norway (Skjellbekken) and Finland (Kirakka, Naruska, Pallas) to determine the environmental impact of local industrial pollution. Results of analysis of snow samples collected in March/April 1994 are presented for both filtered meltwater and filter residues. Many heavy metals (As, Cd, Co, Cr, Cu, Mo, Ni, Pb, V and Zn), as well as S, Al and Fe, are unusually enriched in both phases in the Russian catchments, primarily in Monchegorsk and/or Zapoljamiy. Typically, some elements are found mostly in the meltwater phase (e.g. Na, S, Sr, Zn), others in the filter residues (e.g. Cr, Fe, Mo, Ni). Cu and Ni are well correlated, both in meltwater and in filter residue, and the ratio of Cu to Ni can be useful in identifying pollution sources. Snow is a well-suited medium for fingerprinting environmental pollution sources. Estimates of deposition from snow meltwater only, will be seriously underestimated for many elements.
