The work is devoted to solving the problem of radon mapping of the Taman peninsula as a problem of interaction between the region’s ecosystems and population. An express method of calculating the radon volumetric activity for decay energy of secondary products designed and implemented. Data of the 3-year's field investigations allowed us to plot the map of distribution of radon volumetric activity in the coastal zone of the Azov and Black seas of the Taman Peninsula, as well as over its surface. Some potentially dangerous territory identified. Average values of radon volumetric activity determined in the zones of tectonic disturbances and for the main territory of the Taman.

AbstractThe weathering phenomena resulting from the growth of six foliose and crustose lichens (Parmelia subrudecta, Xanthoria ectaneoides, Parmelia conspersa, Aspicilia radiosa, Caloplaca sp. and Ochrolechia parella) on three mafic rocks have been studied. The bioweathering results in more or less extensive fragmentation and corrosion of the mineral surfaces immediately beneath the lichen thalli and in the formation, in the thallus or at the rock-lichen interface, of secondary products. The significant amounts of whewellite found in all interfaces, and the bipiramids of weddellite detected at the serpentine rock-Ochrolechia parella interface, suggest that the oxalic acid secreted by the mycobiont is the chemical substance principally involved. The capacity of the lichens to alter their rock substrata does not appear to be related to their thallus morphology.

Abstract The title compounds la-3c were prepared by stereoselective reduction of the respective dibromides. Pyrolysis gave allylic bromides (8, 9, 11) as primary and dienes (10, 12) as secondary products. Product ratios were independent of the stereochemistry of the starting materials. No differences of the rearrangement rates of the stereoisomers were observed in gas phase reactions of the derivatives of bicyclo[6.1.0]- and bicyclo[8.1.0]alkanes. With the larger bicyclo[10.1.0] derivatives, however, distinct differences in the thermal stability of cis-trans-isomers4c/5c or 2c/3c were found in condensed phase.

ABSTRACTMany countries have recognized vitrification as the suitable solidification method for conditioning high level radioactive waste before they are isolated from biosphere in geologic disposal. This paper studies the leaching behavior of a simulated HLW-glass (90Nd/10) under low oxygen repository condition during 1.5 years. The leaching results showed that the glass was corroded less under low oxygen condition than under ambient atmosphere. XRD analyses showed some little diffraction peak appeared on the leached glass surface at 150°C. At the same time, no diffraction peak appeared on the leached glass surface at 90°C. The secondary products formed on the surface of the leached glass contained mainly Si, Al, Ca and Fe.

In a number of industrialized regions of the Russian Federation, even when using efficient high technologies in the manufacturing industry under the current linear economic model, especially in the context of pandemic (COVID-19) fails to implement the sustainable development goals in all of its ecological and economic requirements. This paper analyzes models and approaches to the implementation of the concept of renewable production and consumption in conditions of maximum use of resources, including those obtained by processing various types of waste. According to the analyzed one of the models, namely the circulation economic model, resources after consumption in the form of manufactured products and the resulting waste, suitable for processing into production resources, in the form of secondary. Within the framework of rational interaction of the industrially developed regions (Moscow and Kaluga), an experimental confirmation of the efficiency of waste processing of various types is given, by building an Ecotechnopark, implemented within the framework of public-private partnership, and obtaining secondary products. In the proposed circular economic model, resources after consumption in the form of production products are returned to production after processing. In addition, a possible indicator was identified and implemented that allows integrating traditional economic indicators into the "Green" gross national product (GNP), which is the sum of the natural capital of the region and its nominal GNP and is linked to the state of the ecosystem. Recommendations and conclusions on the performed studies are made.

The features of maintaining large-capacity waste from oil and gas fields that are suitable for recycling into secondary products are considered. A step-by-step system for selecting and justifying a waste is proposed taking into account the development of the deposit, its natural and manmade features, as well as the selected stages of operation. Pieces of technological schemes of waste preparation are given, as well as the design of the waste preparation complex for disposal constructed at one of the largest oil fields of the Samara region.
