Systems of environmental management of industrial production and soil-ecological monitoring of impact zones Communication 1. Soil fertility and pollution by heavy metals

The impact zone of a plant that produces phosphorus-containing mineral fertilizers falls into a circle with a radius of no more than 9 km from the object (the upper bound of the estimate). Soils of this territory can be subjected to complex pollution and contain cadmium, lead, strontium and phosphorus in concentrations significantly higher than the conventional (local) and regional background. The location of two foci of complex pollution (out of 42 trial plots) in which the content of total forms of cadmium and lead exceeds the current standards (ODC, MPC) in the upper soil layer (0-10 cm) is established on the territory of the study. At an equal level of anthropogenic load, different types of soils show an unequal ability to accumulate gross and mobile forms of potential soil pollutants. The possibility of formation of a geochemical barrier due to a change in the reaction of the environment has been identified, which corrects the possible impact of hazardous pollutants. When assessing the state of the soil cover and predicting the dynamics of its changes, it is necessary to take into account the effect of emissions from neighboring factories of the production cluster.
