    In this paper we present and discuss factors that influence significantly the reliability of magnetic proxy mapping of anthropogenic pollution of soils. Quantification of these factors in contaminated soils is explained. Importance of individual factors is assessed on the basis of in situ measurements and laboratory experiments. As a result, we propose criteria necessary for reliable assessment of soil contamination due to atmospheric deposition of pollutants using soil magnetometry: a) low lithogenic effect on topsoil magnetic values, b) insignificant contribution of ferrimagnetic particles of pedogenic origin in the topsoil layers, c) migration rate of anthropogenic particles must be estimated in soils with high porosity.
