Mapping of actual concentrations of mobile forms of copper in soils of the northern industrial complex of Volgograd

This paper presents an analysis of the results of a study of the actual concentrations of mobile forms of copper in the soil cover of the northern industrial hub of Volgograd within the assumed zone of influence of local sources of anthropogenic impact. As objects of influence on the components of the environment, the following were selected: a ferrous metallurgyenterprise (JSC “VMK “Krasny Oktyabr”) and a multidisciplinary enterprise (JSC “FNPC “Titan-Barricades”) of Volgograd, characterized by the specifics of the location relative to the functional zoning of the city. Sampling was carried out in 2017-2021 at control points at a distance of 0-4.5 km from the enterprises. During the same period, laboratory studies were carried out using the precision method of atomic absorption spectrometry. A map of the results of monitoring the content of mobile forms of copper in the soil cover in the study area is presented. The identified zone of influence of enterprises, taking into account the presence of additional sources of contamination of the soil cover and the MPC of cuprum, instead of its background concentrations, extends 3-3.5 km from the border of the metallurgical enterprise in the form of elongated areas of increased concentrations. It is noted that there are two pronounced foci of pollution located to the west of the operating SPC of the enterprise, as well as a focus of pollution located outside the boundaries of the sanitary protection zones of JSC “VMK “Krasny Oktyabr” and JSC “FNPC “Titan-Barricades”, in the intersection zone of the 2nd longitudinal highway and General Vatutin Street. The data obtained confirm the expediency of organizing regular monitoring of the soil cover in the city as one of the areas of environmental quality assessment.
