| The paper presents environmental monitoring system for surface atmospheric air in the vicinity of the Rooppur NPP in Bangladesh. A monitoring programme was developed. There were selected 3 observation points. Monitoring objects (atmospheric air and precipitation), a list of observed parameters, observation regulations, as well as investigation methods, were identified. The controlled indicators included the radionuclide composition of surface air and precipitations, involving natural (40K, 226Ra, 232Th) and artificial radionuclides (54Mn, 60Co 90Sr, 137Cs), the content of heavy metals (HM) (Сd, Ni, Pd, As, Hg, Co, Cr, Mn, Cu, Zn, Al, Fe), the gas composition of the air and the level of dust. The investigations were carried out in 2014–2017 before and at the construction stage of NPP considering the climatic characteristics of the region during different seasons. The results of monitoring studies showed the influence of the NPP construction on changes in the content of HM and dust in the surface air and the absence of an increase in the content of radionuclides. The concentration of Pb and Cd after the start of the NPP construction began to exceed current standards by 1.6–2.3 times, due to the operation of the equipment and dust formation. The specific activity of radionuclides in the air was very low. The influence of climate on the dust content in the air during the year was also noted. The values varied from the minimum in the monsoon period (June-September) to the maximum in the dry period (December). Analysis of the gas composition of the air revealed the presence of H2 S (average content 0.12 mg/m3 ), as well as CO (0.57 mg/m3 ) and NO2 (0.39 mg/m3 ). The detected concentrations excepting single measurements of hydrogen sulfide are quite low and do not pose a risk to human health. | ||||

| The article presents the results of monitoring of two plain reservoirs located in the Vyatka-Kama Pre-Urals, according to remote sensing data and field observations. The reservoirs are located in the Kirov region, have similar morphological parameters, the same origin, but differ in the level of anthropogenic load. According to the satellite images taken from the Sentinel-2 satellite (A, B) in the period from May to September 2015–2020, the normalized relative algoindex (NDAI) was calculated. This index allows you to detect accumulations of phytoplankton in reservoirs. The NDAI values do not depend on atmospheric interference and the influence of the reflection spectrum of the water itself. The index images are built in the QGIS software product, version 3.20. The results obtained are compared with the data of field observations on reservoirs. The NDAI values in the water area of the Omutninsky reservoir during the observation period varied from 0.36 to 0.80, in the water area of the Chernokholunitsky reservoir from 0.32 to 0.84. Intensive algae bloom in the studied reservoirs was observed in August 2016 and July 2020. In the areas of water areas where intense algae blooming was noted, the following species prevailed in the phytoplankton samples: Anabaena lemmermannii P.G. Richter, A. spiroides Klebahn, A. planctonica Brunnthaler, Aphanizomenon flos-aquae Ralfs ex Bornet & Flahault. The optical density of water in this case was from 0.150 and higher (the length of the optical path of the cuvette is 10 mm, λ = 615 nm), and the NDAI values were more than 0.55. | ||||

||||
| The results of long-term restoration of vegetation on the dumps of a spent gold mining in the Kozhim River basin (Circumpolar Urals) are presented. 25 years after the finishing of gold mining, only an small part of the industrial territories open groupings and unclosed plant communities are formed. Significant areas of dumps remained practically lifeless. Biodiversity increases over time up to 212 species for vascular plants and up to 27 species for bryophytes. The composition of plant groups and phytocenoses is characterized by significant variability. This is due not only to unfavorable environmental conditions, but also to the random introduction of seeds. Primary successions during the observation period did not occur according to the zonal type, although the appearance of the emerging vegetation was determined by species of natural flora. | ||||

| The relevance of preserving the genetic resources of the animal and plant world necessitates the search for biologically active substances for the preservation of reproductive cells. Under conditions of hypothermic storage, the osmosis of the extracellular environment, stabilization of membranes and the structure of the cytoskeleton of cells can be provided by various sugars. Xylotrophic Basidiomycete Hericium erinaceus (Bull .: Fr.) Pers. is a source of polysaccharides with high biological activity. Residues of galactose, glucose, arabinose, mannose, fucose, rhamnose, xylose (in order of decreasing % content) were identified in the carbohydrate chains of the polysaccharide fraction (PP) of H. erinaceus BP 16. The effect of PP of different concentrations on the freezing of water in an aqueous solution of glycerin, as well as on the viability of spermatozoa of Holstein bulls under hypothermic (+ 4 °C) storage conditions, on the intensity of LPO processes and antioxidant activity, on the ability of gametes for progressive movement, on sperm resistance to hypoosmotic stress. In connection with the search for new effective components for preserving solutions, the data obtained in this work indicate the prospect of using the PP of H. erinaceus as a component to slow down the rate of ice crystallization in cell suspensions during freezing and as an antioxidant regulator of the functional usefulness of gametes during cooling | ||||

| The dynamics of fires in the middle taiga subzone in the northeast of the European part of Russia in the Holocene are presented. Peat soils (Histosols) on the territory of the Komi Republic have been investigated. Dendrochronological studies and assessment of the content of macroscopic charcoal particles in peat were carried out at the sites. Radiocarbon dating values were obtained, which allowed us to build models of the rate of vertical growth of peat deposits and identify time intervals with frequent fires. In the course of the work, it was revealed that the studied middle taiga landscapes of the Komi Republic (Mezensko-Vychegodskaya Plain, Severnye Uvaly, foothills of the Northern Urals) have a similar history of paleofires. The paper shows that the maximum content of macroscopic charcoal particles is observed in the lower peat horizons dating from the Boreal and Atlantic periods of the Holocene (10,200 to 4,500 years ago). The Subboreal period is characterized by a significantly lower number of forest fires compared to the Atlantic and Sub-Atlantic periods. The upper peat horizons, dating from the end of the Sub-Atlantic period, contain information about the increase in the frequency of fires at present time. Regularity has been revealed according to which during the warm periods of the Holocene, stable forms of carbon as a result of frequent fires were accumulated significantly more than during the cold periods. | ||||

| The analysis of the existing system of surface water monitoring in Russia is carried out. The methodological and practical problems that arise when monitoring the surface water bodies of the country are identified. It is noted that in order to improve the monitoring system of water bodies in Russia, first of all, it is necessary to update existing monitoring programs, more widely use modern equipment, methods of remote sensing of the Earth and information technologies. The list of indicators to be assessed when monitoring water bodies should be compiled in accordance with the environmental characteristics and the nature of the use of the water body, taking into account new types of pollutants entering water ecosystems, the transformation of substances in the reservoir, the probability of secondary water pollution by biogenic elements and toxic substances as a result of diffusion from pore solutions of bottom sediments. The current issue is the regulation of the impact of various substances on the state of aquatic ecosystems. Possible solutions to this issue are the development of regional standards for assessing the state of water bodies, the transition from a hazard-based approach to a risk-based approach to normalizing the impact on water bodies. | ||||

| The overview the results of a full-scale inventory and long-term monitoring observations of the occurrence and abundance of butterflies in Specially Protected Natural Areas of the Komi Republic is presented in this paper. It has been established that the republican network of protected areas includes habitats of 115 representatives of the superfamily (about 86% of the composition of the regional fauna). It is concluded that most of the protected areas of the Komi Republic of federal and republican significance a fully performing the function of preserving species diversity, the landscape-zonal structure of the fauna and the spatial-typological structure of the Lepidoptera population of the Papilionoidea superfamily in the northeast of the Russian Plain and in the northern regions of the Ural Mountains. The IUCN assessment of the risk of extinction the Lepidoptera suggests that the network of protected areas of the Komi Republic plays a crucial role in the conservation of the gene pool of species included in the regional Red Book. To meet these challenges, it is necessary to organize monitoring observations of the state of populations the rare species and the dynamics of species diversity the butterflies in support protected areas and in key habitats. | ||||

| The article analyses opportunities for enhancing resource and environmental efficiency of modern electroplating processes. These parameters highly depend on metal and water use efficiency. Water is consumed primarily for washing details after the plating. Authors analyse reasons for changing water intensity of electroplating processes and opportunities for reducing water consumption while implementing Best Available Techniques (BAT). Data on solution carry-over published in the research literature, norms and standards are compared. Various periods of the technology development and environmental regulation are considered (1939 to date). Specific water consumption grows since 1970s which is caused both by the increase of concentrations of main components of technological solutions and by the introduction of GOST 9.047-75 standard. The standard sets an elevated solution carry-over value: if in 1959–1968, this value varied between 0.055 and 0.073 L/m2 , in 1972 the new value was set at 0.2 L/m2 . Authors assume that this decision was caused by the environmental regulation requirements which became more stringent at that time. Increased solution carry-over norms allowed using water to dilute wastewater and thereby to reduce concentrations of contaminants. The average solution carry-over value is 0.065 L/m2 , while the most probable values vary between 0.04 and 0.08 L/m2 and may be considered as environmentally and resource sound when setting BAT requirements for designing electroplating processes. For the two-stage washing process, parameter (qK1/2) is calculated. This parameter characterises the specific washing water volume. Annual water consumption in the electroplating processes is assessed. The consumption calculated based on existing norms, varies from 3.4 to 6.2 mln m3 per year; it is 2.5 times higher than the consumption reported in the research articles. | ||||

| The biodiversity of underground habitats is of considerable interest from different standpoints, but information on the biota of the caves is incomplete and fragmentary. In this regard, the identification of different factors that influence the richness of species of various organisms, including cyanobacteria and algae, is important. 166 different samples, which were collected in 2007-2012 from 14 karst caves of natural origin, located in various climatic zones of Russia, were investigated. 121 species and intraspecific taxa of cyanobacteria and algae belonging to five phyla (Cyanobacteria, Bacillariophyta, Ochrophyta, Chlorophyta, Streptophyta) were identified in the studied caves. Based on the obtained material, the influence of some abiotic factors (the stage of karst speleogenesis, the length of the cave, and the area of the entrance, the underlying rocks and the surface climate) on the biodiversity of cyanobacteria and algae was analyzed using statistical methods. The speleogenesis stage (the influence of the factor is 118.419, p < 0.05) most effect on the species richness of cyanobacteria and algae in the studied caves that directly related to the level of water. Also the underlying rocks (the influence of the factor is 34.665, p < 0.05) and the length of the cave (the influence of the factor is 20.288, p < 0.05) effect on the biodiversity of cyanobacteria and algae in these caves. It was revealed that the relationship between the total number of species of cyanobacteria and algae and the various stages of speleogenesis is statistically significant (p < 0.05), and the species richness of these organisms decreases from the corridor-grotto stage to the corridor-grotto-chamber stage. The number of species of Cyanobacteria and Bacillariophyta also decreased statistically significantly (p < 0.05) in the stages of karst speleogenesis: corridor-grotto, corridor-grotto-lake, corridor-grotto-chamber. | ||||

| The multifunctional biopreparation (MB) containing bacterial cells of Bacillus subtilis 26D (ARRIAM 128), Bacillus thuringiensis ssp. thuringiensis (VKPM B–5689) and Bacillus thuringiensis ssp. kurstaki (VKPM B–6066) for increasing crop yields and protect them from pests and diseases was developed. Assessment of protective and growth-stimulating properties of MB in the field revealed that two-time treatment of spring wheat plants Vatan variety with the 2 kg/ha MB allowed obtaining the maximum increase of harvest. It amounted to 0.48 t/ha of grain in comparison with the control (water treatment). The efficiency of MB application for protection of wheat against aphids was 100%. The use of a single and double concentration of mixture of biofungicide Phytosporin–М (B. subtilis 26D, 2×109 CFU/g, 1 kg/ha and 2 kg/ha) and bioinsecticide Bitoxybacillin (1 kg/ha and 2 kg/ha) did not allow to obtain an effect equal to MB influence. The developed ecological safety microbiological consortium was recommended as the basis of biopreparation with multifunctional activity | ||||
