dc.abstract.enTopsoil contamination near the Stanisław Siedlecki Polish Polar Station (PPS), Hornsund, Svalbard, has been assessed using magnetic methods supplemented by chemical analyses and microscopic observations. Analysis of magnetic parameters has enabled to evaluate the concentration, magnetic mineralogy, and grain-size distribution of anthropogenic magnetic particles. Heavy-metal contamination near the PPS originates primarily from local sources. Anthropogenic spherical, magnetite-like particles were found near the station, whereas uncontaminated topsoil is devoid of such particles. Magnetic studies indicate that magnetite and goethite are the primary magnetic phases, with magnetite levels being higher in polluted area. Magnetic fraction of contaminated topsoil includes a mixture of single-domain and multi-domain grains, while uncontaminated topsoil contains smaller grains. Results show a clear correspondence between Pollution Load Index and magnetic susceptibility anomalies, and that the areal extent of PPS impact on the environment has not expanded significantly since 2004 (although a new contamination source, the scrap yard, is now present). A comparison of magnetic susceptibility measurements with metal analyses indicates that magnetic methods can be used as a rapid, inexpensive, non-invasive, and sensitive tool for the evaluation of topsoil contamination.
