Abstract: A geophysical survey conducted in the remote forest glade, located in the IzeryMountains (SWPoland), revealed the existence of an anthropogenic layer of historical glasswastes dumped in this area during the activity of a glass factory in the 18th and 19th centuries and domestic wastes dumped during the second part of the 20th century. The aim of the study was assessment of potential ecological risk related to the release of potentially toxic elements to the soil, groundwater and surfacewaters. The assessmentwas done on the base of classical geochemical analysis supported by calculation of environmental indices as well as on mobility of elements (leaching test and BCR sequential extraction). As an innovative aspect in the geostatistical interpretation of the data, somemagnetic parameters (magnetic susceptibility-χ, χ/Fe ratio)were also used. It allowed for a better understanding of the relationship of PTEs with various forms of iron. The BCR sequential extraction found that among the PTEs, only Zn (up to 43%)was in a potentially mobile fraction probably occurring in ionic form, associatedwith iron oxides only by surface adsorption forces. The leaching has shown a slight increase in Zn and Cu content in the surfacewaters; however, itwas not considered to be a real ecological threat because the pHof thewastematerial and soil cover is N6.0 and the scenario of a radical decrease in pH is rather unrealistic. The other PTEs were associated with more stable E2, E3 and E4 fractions. Zinc, similar to Ni, Co and Cu inwaste samples,was highly correlatedwithmagnetic parameters (χ and χ/Fe). Itmeans that a considerable part of these metalswas associatedwith ferrimagnetic iron oxides, although they can also occur in the form of inclusions in aluminosilicates and enclosed in glassy phases.
