Abstract Ferrimagnetic minerals of anthropogenic origin derived from fossil-fuel combustion, appear not only in industrial areas but also in topsoils of areas remote from the main sources of pollution. Mineral magnetic studies of fly ashes emitted by power plants burning hard and brown coal and of soil profiles from some Polish national parks in different regions were carried out. Magnetic parameters of topsoils from national parks are quite similar to those in flyashes. Structure, shape, and magnetic granulometry of the magnetic particles in the fly ashes and in the magnetically enhanced uppermost organic soil horizons point to a common origin. This fact as well as the ability of ferrimagnetic minerals to be transported within dusts or aerosols suggest that ferrimagnetic particles of anthropogenic origin can be responsible also for magnetic enhancement in soils of areas remote from the main sources of their emission. Industrialdust deposition can be easily traced in these areas using magnetic methods, which are very sensitive, fast, and cheap. They can, and should, be used in the future as one of the routine methods of soil monitoring.
