Chemical reactions and conditions of mineral formation at tailings storage facilities of the Russian Far East

Cassiterite-sulfide and polymetallic deposits of the Far Eastern Region (FER) were mined by both openpit and underground methods. This resulted in the emerging numerous mine workings and tailings storage facilities (TSFs) (abandoned without reclamation in latest decades) and the formation of mining technogenic mineralogical systems. Sulfide component of minerals in the mining technogenic system is subjected to hypergenic and technogenic processes (oxidation and hydrolysis reactions). As a result, highly concentrated technogenic solutions are formed, from which minerals of various classes precipitate. In this connection the purpose of this study was formulated as follows: to show the possibility of crystallization of technogenic minerals from micropore technogenic solutions. In achieving this goal the following tasks were solved: to demonstrate the possible reactions of oxidation and hydrolysis of technogenic minerals at the tailings storage facilities; to identify Eh-pH parameters of their precipitation from highly concentrated solutions; to determine their possible associations. The studies involved field observations and computations with the use of “Selector” software package. The study findings allow demonstrating possible chemical reactions and physico-chemical conditions of mineral formation for the following elements: Fe, Cu, Pb, Zn, Sb, Mg, Al, and Ca, including the following classes of minerals: oxides and hydroxides, sulfates, carbonates, arsenates and silicates. The paper presented for the first time the crystallization reactions of secondary minerals (37 ones) and their physico-chemical conditions. It was found that secondary minerals: jarosite, pitticite, siderite, tenorite, poznyakite, antlerite and ktenasite crystallize in the interval of positive temperatures, while scorodite, chalcantite, broshantite, cerussite, starkeyite, epsomite and rostite originate in cryogenic conditions (below 0 oC). All other minerals, the possibility of precipitation of which was shown in the paper, crystallized in the whole considered temperature interval, from −25 oС to +45 oС. Field studies and modeling data on formation of technogenic waters (solutions) and crystallization of secondary minerals on the surface of and inside tailings at the tailings storage facilities of the Far East showed high intensity of technogenic processes. Since the tailings storage facilities were not reclaimed, the process of environmental pollution, including the hydrosphere, would last for many decades.

The Russian Far East

Purpose of the study: The purpose of the article is to study the characteristics of the stigmatization process of modern youth in the Russian Far East. Special attention is paid to living conditions in the Russian Far East, noting that the majority of the population in the Far Eastern region and, above all, young people, are in a situation of social inequality and marginality in relation to the rest of Russians. Many young people associate their life strategies with leaving the territory of the Far East of Russia. Methodology: At the first stage of the study, the method of participant observation was used, which provided primary information about the impact of stigma on the self-identification of young people. At the empirical level of research, such sociological methods as document analysis, sociological surveys in the form of questioning and interviewing were applied. A sociological survey was conducted as a pilot study of the problems of stigmatization among high school and university students of the cities of Khabarovsk and Komsomolsk-on-Amur. Main findings of this article: Stigma is manifested in its own way in different times and in different communities, it is historically and socioculturally specific. Territorial stigma possesses signs of ambivalence, on the one hand, it has a negative effect on the socialization and self-identification process of young people in the Russian Far East, but on the other hand, it can act as an incentive for young people to make an active and conscious choice of their life strategy. Applications of this study: The findings can be used in the implementation of youth policy in the Far Eastern Federal District by state and local authorities in order to prevent the outflow of young people from the region. The main results of the study can be useful for use in the educational process in such disciplines as sociology, political science, regional studies, as well as for the further study of the problems of social stigmatization. Novelty/Originality of this study: The novelty and significance of the study lie in the fact that in Russian sociology practically no attention is paid to the problems of territorial stigmatization. The theoretical conclusions were obtained on the basis of the original sociological research conducted by the authors of the article in the cities of the Far Eastern region of Russia. The results provided new knowledge of both territorial stigmatization and social stigmatization in general. The novelty of the conducted study lies in the actualization of the problem of social stigmatization of Russian youth living in the Far Eastern region remote from the center of Russia.

The article is devoted to the issues related to the study of the process of identification and professional self-organization of public relations specialists in the Far-Eastern region of Russia. This process is studied from the point of view of defining the group identity, group norms, and the activities of professional communities. The empirical basis of analysis was the results of an expert survey of public relations specialists in the Far-Eastern federal district. The authors identify the current professional PR communities of the Russian Far East, identify the motives of their members for more active participation in the communities life. There is an independent association of representatives of professional group due to the grassroots activity «spontaneous self-organization» and the presence of experience in consolidating PR specialists in a specific field (state) with an external actor. It is concluded that today there is a willingness of the self-organized PR community to participate in solving the socially significant issues for the region, the development of inter-sector partnership, as a result of formation of trusting attitude of population to the decisions taken in the region.

The article is devoted to the introduction of the term ‘Jōmon’ into Russian archaeological literature, its understanding, and the contribution of Russian scholars to Jōmon studies starting from the late 20th century. The recognition of the term and its use had some peculiarities which were caused not only by the language barrier and political events in the far eastern region, but mostly by the specifics of the archaeological investigations in the Russian Far East and the priority of research focused first on the Ainu origin, and then on the Palaeolithic rather on the nature of the Neolithic. The rise of the interest in Jōmon grew in the late 1960s and early 1970s with the discoveries of initial pottery with Final Pleistocene dates in Japan and Russia (Lower and Middle Amur Region). During the 1980s and 1990s this trend was realized in a series of publications, international conferences, and the first joint Russian-Japanese archaeological projects. The current stage is illustrated by the institualization of several research centres of Jōmon studies in Russia (Novosibirsk, Vladivostok), by a high level of international cooperation, and by a wide range of research topics, including chronological, technological, ritual and other aspects of the Jōmon period.

The aim. The problem of accumulation of organochlorine compounds (OCPs) in the human body is relevant, because these substances have potential teratogenic, carcinogenic, hormonal, neurological and immunological properties. Thus, the purpose of the work is to identify trace organochlorine compounds (α, β, γhexachlorocyclohexane (HCH), dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethane, dichlorodiphenyldichlorethylene (DDE)) in the blood and urine of the residents of the south of the Russian Far East. Methods. The urine and blood of residents of the south of the Russian Far Eastern region were examined by gas chromatographymass spectrometry to study the content of OCPs trace concentrations. Results: α and γisomers of hexachlorocyclohexane (HCH), dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichlorethylene (DDE) were detected in the urine. Only βHCH in the blood was detected. Conclusions. The spectrum of basic OCPs in the urine indicates the possibility of its excretion by the body; however, the detection in the blood of only βHCH indicates a longer retention of the latter as the most stable isomer. A comparative evaluation of the obtained results with the data of other authors showed that the detected concentrations of cholesterol in the blood of residents of the Far East were lower than in typical agricultural countries and were found in no more than 30 % of the sample.

The Russian Far East

Eutheia Stephens, 1830 is distributed in Holarctic and Neotropical regions, with a majority of species known to occur in the Palaearctic. Recent studies focused on the Russian Far East, China, Taiwan and Japan yielded many new species (Hoshina 2007; Jałoszyński 2004, 2008a, 2008b, 2010a, 2010b, 2013; Kurbatov 1990, 1991). Central and South Asia are very poorly studied, as these areas include several countries whose geopolitical situation makes field studies difficult. Besides two Himalayan species of Eutheia discovered in Nepal (Franz 1974, 1985), the scydmaenine fauna of the vast area comprising Afghanistan, Pakistan and some of the former Soviet republics is very poorly known. Southern areas of this region (mostly India) are better studied, but as Eutheia prefers temperate climate and even in the Neotropics and in Taiwan can be found only in high mountains (Jałoszyński 2008b, 2011), it is not very likely to find this genus far south of the mountain arc formed by the Himalayas, Karakoram and Hindu Kush. Pakistan, with its potentially species-rich, forested sub-Himalayan region with a subtropical highland climate, is exceptionally poorly studied, with only four species of Scydmaeninae recorded: Scydmoraphes gartneri (Franz, 1979), Scydmoraphes hastipes Vít, 1999, Stenichnus fallax Vít, 1999 (all Glandulariini), Scydmaenus minangkabauensis C. Blattný, 1926 and Scydmaenus ravalpindii Franz, 1970 (Scydmaenini). However, some of these species remain problematic. The identity of Pakistani material of Sc. minangkabauensis remains unclear, as this species was described from Sumatra, and recorded from Vietnam, southern China, Java, Sri Lanka, Nepal and Pakistan (e.g., Franz 1982). Such a broad distribution seems unlikely, especially that many species of Scydmaenus share very uniform appearance and their aedeagi were often studied and illustrated by Franz just in any possible view, depending on how they solidified in euparal, without making any attempt to obtain repeatable preparations. Stenichnus fallax, in turn, is very likely a junior synonym of Stenichnus rothangensis (Franz, 1981), a species redescribed by Jałoszyński (2015) and known to occur in the Indian state of Himachal Pradesh, not far from the type locality of St. fallax.
