Assessment of topsoil contamination near the Stanisław Siedlecki Polish Polar Station in Hornsund, Svalbard, using magnetic methods

Topsoil 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,...
