“…Figure 4 shows that the number of samples in which the total iron concentration does not exceed the MPC is very small, and an excess of 1-5 and 10-32 times is observed in 20 and 19 samples, respectively. Thus, the above data indicate a strong iron contamination of the total water bodies of the Leningrad region, which requires the development of special measures to improve their ecological state [6][7][8].…”

The authors of the article studied the rivers and lakes of the Leningrad region of the North-West region of the Russian Federation for the total iron content and analyzed the results obtained. This chemical indicator is being investigated due to the fact that it can have an adverse effect on the environment and human health. The main goal of the work was to analyze the most polluted water bodies of the Leningrad region in terms of excess of the maximum permissible concentration (MPC) for total iron and to develop a way to reduce its concentration. A colorimetric analysis method was used to obtain the data. Exceeding the maximum permissible concentration for total iron was found in more than 80% of samples. A detailed analysis of the three most polluted water bodies was carried out. The results obtained showed that the water bodies of the Leningrad region are heavily contaminated with common iron. In this regard, it is required to develop special measures to reduce its concentration. The authors suggest the use of gabion structure with a special filler for bank stabilization and reduction of the concentration of total iron to the most polluted rivers of the Leningrad region.

“…When filling a granite quarry at a maximum point of volume/height, an area of ~ 51 hectares is formed. After the biological reclamation stage, the obtained area can be used for forestry purposes as a nursery, or used as a forestry territory (restoration of the geoecological system in a particular region) [9][10][11][12][13][14][15][16].…”

The relevance of the problem under study is due on the one hand to the need to reclaim disturbed areas formed as a result of construction activities, on the other hand to the need to find useful use of demolition products of buildings and structures. The purpose of the work is to study the possibility of using multimodal logistics for the use of demolition products in the reclamation of disturbed areas, using the example of granite quarries. Geoecological, technological and economic forecasting of multimodal logistics of urban agglomeration demolition products will allow to develop the most optimal schemes of their useful use. As a result of research, mathematical models have been developed for predicting the formation of a transport and logistics chain for the removal of demolition products from objects. For the first time, a scheme has been developed for choosing a method of moving demolition products depending on the range of the burial place for making substantiating decisions on their removal in the process of designing measures for the reclamation of granite quarries from the point of view of geoecological and economic expediency. It is scientifically justified to use demolition products as fillers of spent granite quarries for temporary storage, partial or complete filling with subsequent reclamation of spent quarries. The materials of the article can be useful for the development of technological solutions for the reclamation of disturbed areas using demolition products of buildings and structures.

“…One of the effective and safe solutions for the neutralization of technogenic soils from heavy metal ions is associated with their conversion into difficult-to-dissolve substances, which are close in chemical composition and structure to safe natural minerals [6][7][8][9][10][11]. The main method for substantiating geoecological protective properties is a thermodynamic assessment of the reactions of interaction between ions of heavy metals and mineral geoantidotes, as well as an assessment of the product of solubility of substances formed during their interaction [12][13][14][15].…”

The need to protect technogenic soils from contamination with heavy metal ions determines the relevance of the topic under study. The aim of the work is to thermodynamically substantiate the ability of gypsum and magnesia stone to neutralize heavy metal ions. Such properties of gypsum and magnesia stone can be called geoecological protection, and the substances themselves can be called mineral geoantidotes. The main method for substantiating geoecological protection properties is a thermodynamic assessment of the reactions of interaction between ions of heavy metals and mineral geoantidotes, as well as an assessment of the solubility product of substances formed during their interaction. As a result of the research, the values of changes in the Gibbs energy during the interaction of mineral geoantidotes and heavy metal ions have been determined; it has been shown that possible products of interaction reactions can be minerals similar to natural ones. Calculations have shown the possibility of reactions occurring under non-standard conditions (1 to 40°C). The experiments carried out made it possible to determine the geoecological protective capacity of gypsum and magnesia stone in non-standard conditions and showed the absence of dependence of the geoecological protective capacity on the ambient temperature in the range from 1 to 40°C. The materials of the article can be useful for the development of technological solutions to reduce harmful pollution by ions of heavy metals of technogenic soils using gypsum and magnesia stone.
