PRINCIPLES AND METHODS OF DIAGNOSTIC AND MONITORING OF HEAVY METALS IN THE SOIL OF URBANIZED AREAS

The necessity of improving the monitoring of heavy metal contamination of the soils of urbanized areas using a complex of chemical-analytical and biodiagnostic methods is substantiated. It has been proven that for the soils of urban landscapes it is not enough to assess the level of pollution only by the excess of the content of heavy metals, and it is necessary to supplement the methods of chemical and analytical research with biodiagnostic methods, in particular, phytotoxicity data.
