Composition of the magnetic phase of soils on the territory of the protected area “Chernyaevsky Forest“ (Perm)

Abstract

The territories of industrial cities are objects of active human influence on various natural processes. One of the most acute problems of the present time is the contamination of soils with heavy metals (HM). The main carrier phase of TM in urban soils is technogenic magnetic particles. A common group of particles of technogenic origin are magnetic spherules. The origin of magnetic spherules is associated with the work of industrial enterprises of metallurgical profile, thermal power plants and motor transport. The study of the morphology and composition of the magnetic phase of the soil allows us to identify the sources of pollution. According to the results of magnetic susceptibility, the content of heavy metals and magnetic particles in soils, the level of contamination and their ability to resist it are evaluated. Forest soils are the most sensitive to pollution. Therefore, the study of the composition and properties of magnetic spherules as potential environmental pollutants in Perm is relevant. The composition and properties of magnetic spherules of forest soils in Perm remain poorly understood.
