Environmental assessment of soil pollution by heavy metals within the boundaries of roadside areas

Abstract

The work is devoted to the environmental assessment of degree of soil pollution with heavy metals on land plots, located within the boundaries of roadside territories. The study area is characterized by uneven anthropogenic load on different sections of the road. The article examines the indicator of lands ecological state, taking into account heavy metals content, their toxicity, excess of background level. As a result of the research, it was revealed that the excess of the MPC was recorded for two elements of the 1st hazard class - lead and zinc. Thus, the 5-meter zone belongs to the category of very strong pollution (2 MPC for lead, 1 MPC for zinc, and the zone from 25 to 50 m is slightly contaminated). This algorithm can be used for an integral and ecological-economic assessment of soils of land plots, located within the boundaries of roadside territories.
