| Abstract: | A need for rapid and inexpensive (proxy) methods of outlining areas exposed to increased pollution by atmospheric particulates
of industrial origin caused scientists in various fields to use and validate different non-traditional (or non-chemical) techniques.
Among them, soil magnetometry seems to be a suitable tool, at least in some cases. This method is based on the knowledge that
ferrimagnetic particles, namely magnetite, are produced from pyrite during combustion of fossil fuel. Besides the combustion
processes, magnetic particles can also originate from road traffic, for example, or can be included in various waste-water
outlets. Magnetite, Fe3O4, ranks among the main ferrimagnetic minerals and its identification in various ecosystems can contribute to fast and simple
outlining of areas and sites exposed to higher pollution impact. Here the method of magnetic mapping of anthropogenic pollution
will be introduced using a review of our recent case studies on different ecosystems in the Czech Republic and Germany.
