摘要

The integrated characteristics of urban soils included the assessment of heavy metal pollution linked to the determination of soil genotoxicity, which characterizes the soil capacity to affect the structural and functional state of the genetic apparatus of soil biota. Increased concentration of chromium caused by the high background level was found in soils of the city of Rostov-on-Don. A weak contamination of surface horizons with lead and arsenic was also noted. Maximum permissible concentration of zinc was locally exceeded, including deep soil horizons. It was found that there is no definite correlation between the total content of heavy metals, their mobile compounds, and the parameters of genotoxicity in the natural and anthropogenically transformed soils. It was concluded that soil genotoxicity characterizes the total mutagenic activity associated with the presence of a set of genotoxicants of different nature.
