The aim of this study was to determine the chemical composition and antioxidant potential of the apricot pomace extract (АСЕ). The apricot pomace was extracted using ethanol (EtOH), silicone (D5) and a mixture of silicone and ethanol. The chemical constituents were analyzed by gas chromatography-mass spectrometry (GC-MS). The antioxidant capacity was evaluated using a variety of antioxidant assays (total antioxidant activity, reducing power and catalase activity). Quantum chemical descriptors such as the frontier orbital energies (E HOMO and E LUMO), the energy gap between E LUMO and E HOMO (ΔE), hardness, and electrophilicity index have been calculated and discussed.

The paper presents an analysis of the impact of the enterprise on the state of the soil layer. The impact was considered as a complex of separate physical and physico-chemical processes. To do this, we used the method of determining the cleaning efficiency indicators developed by the author, which is based on a simulation experiment. The algorithm for conducting a simulation experiment on a set of models was used, taking into account the established coefficients, and 10,000 of its implementations were carried out. As a result of using the simulation experiment, the values that allow judging the quality of geofiltration have been determined. The risk of contaminant penetration into groundwater through the soil layer was analyzed based on the Harrington desirability scale. The obtained results that contain the dependence of the probability of complete cleaning of the pollutant with depth. During the passage of the filtration flow at a depth of 2.5 m, the maximum probability of complete purification for copper is reached, equal to ����=0.6086.
