    Soil magnetometry has proved to be a helpful auxiliary method for outlining potentially contaminated areas. Magnetic susceptibility of topsoils may reflect concentration of atmospherically deposited anthropogenic iron oxides, which often coexist with harmful substances, such as heavy metals. Magnetic mapping of topsoils yields unambiguous results in areas with high concentration of pollutants and soils developed on iron-poor geologic basement. In this chapter we review the approach and results of magnetic mapping in a relatively clean area, characterized by rather complex topography. Surface measurements of magnetic susceptibility were carried out after previous examination of its vertical distribution in topsoils and complex laboratory measurements of other magnetic parameters as well as scanning electron microscopy observations.
