This paper presents studies on the possibility of utilization of technogenic waste from the metallurgical industry by the method of complex processing in order to reduce the anthropogenic load on the environment of the region with the example of the zinc silicate-magnetite-carbon system. The selected sample of clinker dump from welting was subjected to chemical and scanning electron microscopic analyses and thermodynamic modeling. Thermodynamic studies were carried out in the temperature range 1600–2200 K and pressure p = 0.1 MPa, modeling the process of electric melting of clinker from welting in an arc furnace using the software application Astra 4 developed at the Bauman Moscow State Technical University (Moscow, Russian Federation). As a result of the thermodynamic modeling, the optimal temperature range was established, which was 1800–1900 K. Thermodynamic studies established that it is possible to drive away zinc from the system under study by 99–100% in the entire temperature range under study. The maximum degree of silicon extraction (α_Si) in the alloy is up to 69.44% at T = 1900 K, and the degree of iron extraction (α_Fe) in the alloy is up to 99.996%. In particular, it was determined and proved that clinker waste from welting can act as a secondary technogenic raw material when it is processed as a mono mixture to produce iron silicides with a silicon content of 18 to 28%.

Today, one of the important tasks that is set before environmental monitoring is to continuously obtain the necessary data on the state of the environment through the use of remote sensing techniques. It should be noted that remote sensing (hereinafter – RS) is used in the technogenic environment of mankind, which directly creates unfavorable conditions, increasing the statistics of the origin of various types of carcinogenic risks. The growing consumption of electric energy leads to the construction and commissioning of new energy facilities, as well as to the construction of high-voltage power lines in the residential environment. An important task in this direction is the establishment of sanitary protection zones, taking into account environmental restrictions, which is aimed at reducing social tension among the population located in the zone of active exposure to the electromagnetic field. Given that low-frequency energy objects, like other man-made objects, are characterized by dynamic characteristics and require constant monitoring of the course of changes in continuous processes, which directly affects the change in the intensity of the electromagnetic field. In turn, the modern information platform allows you to simultaneously conduct environmental surveys to identify carcinogenic risks in the selected area at a specific time by entering the necessary data, which are the main factors in setting the maximum permissible conditions. The development of digital maps based on Arc GIS application programs has a simulation characteristic and allows you to visually assess the dynamics of environmental changes with different variations.

Low-intensity light (LL; 100 µmol m–2 s–1PPFD) effects on growth and biochemical parameters indicative of acclimation were investigated on 21-day-old broccoli seedlings. LL stress reduces the biomass and thickness of the leaf. However, the leaf area was considerably increased. Nevertheless, LL stress noticeably increased the quantity of chloroplast. However, the length and width of stomata were reduced markedly. LL stress led to an increase in the chlorophyll level and reduced the content of anthocyanin and flavonoids. The composition of carotenoids and chloroplast membrane lipids of leaves was significantly altered by LL stress. LL stress-induced responses were closely associated with the generation of superoxide anion and hydrogen peroxide. Concomitantly, lipoxygenase activity was significantly elevated in the leaf tissue, leading to the accumulation of malondialdehyde, indicating oxidation of membrane lipids. The activities of catalase and superoxide dismutase were prominently reduced by ca. 2.11- and 1.6-fold, respectively, by LL stress. However, there was a remarkable induction in the activities of peroxidase and glutathione reductase by ca. 31.5 and 40.8%, respectively, which was influenced by LL stress. Although, no manifest effect in the activities of monodehydroascorbate reductase and dehydroascorbate reductase was noticed in LL stress and control grown leaves. Furthermore, LL stress distinctly decreases the level of ascorbate and dehydroascorbate, whereas the level of the glutathione pool (glutathione and oxidized glutathione) is markedly increased. Our results concluded that the elevated level of reactive oxygen species (ROS)-induced oxidative stress was responsible for the inhibition of growth under LL stress. The stimulated antioxidants did not effectively reverse the LL stress-induced ROS generationin leaves. The changes that occurred in the membrane lipids are possibly the consequence of modifications in the physiology of plants to endure function of the thylakoid membrane to keep physiological functions dynamic to tolerate LL stress environments. The results hypothesize that broccoli growing under shady conditions might not provide a better adaptation for plants.
