Anthropogenic activities, especially industrial processes,
give rise to harmful emissions containing various magnetic
minerals occurring in different amounts. These emissions
are absorbed by the soil, sediments and plants through the
atmosphere and runoff processes, and then change the circulation
and existing conditions of the magnetic materials,
therefore these special magnetic characteristics of the modern
environment are all marked by human activities. The
structure, type, concentration and particle size of these
magnetic particles differ from those of the primary and
secondary magnetic minerals occurring in the environment
[1–7]. Moreover, magnetic particles are associated with
elevated metal concentrations [8–14], especially Cu, Pb and
