Sources of Magnetic Particles from Air Pollution in Mountainous Area

Measurement of magnetic susceptibility topsoil represents a very useful tool for the detection atmospherically depositedmagnetic particles. The samples forest soils from Moravian-Silesian Beskydy Mountains (the Czech Republic) were used foridentification emissions sources particles with ordering. Magnetic was measured at bulk ofgrain size class under 2 mm.
