Currently, perfluorooctanoic acid (PFOA) has no hygienic standards in the air of the working area and objects of the human environment in the Russian Federation. By the decision of the Stockholm Convention SC-9/12, PFOA, its salts and derivatives are included in Part I of Annex A of the Stockholm Convention on Persistent Organic Pollutants in 2019 (with exceptions for possible use). The Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade included PFOA, its salts and derivatives in the list of potential candidates for inclusion in Annex III of the Rotterdam Convention at the next meeting COP10 in 2021. The use of this chemical on the territory of the Russian Federation entails water and air pollution. Industrial emissions and waste water from fluoropolymer production, thermal use of materials and products containing polytetrafluoroethylene, biological and atmospheric degradation of fluorotelomer alcohols, waste water from treatment facilities are the sources of the release of PFOA into the environment. Analysis of international databases has showed that PFOA is standardized in the air of the working area in Germany, Japan, and Switzerland. In the countries of the European Union, as well as the USA and Canada, the issue of PFOA standardizing in drinking water is being now actively under discuss. Taking into account the high toxicity and hazard of the substance and the serious concern of the civil society of the Russian Federation, the Federal Service for Supervision of Consumer Rights Protection and Human Wellbeing requested the Russian Register of Potentially Hazardous Chemical and Biological Substances to develop MACs for perfluorooctanoic acid in the air of the working area and water as soon as possible. The MACs for PFOA have been proposed using risk analysis: 0,005 mg/m3, aerosol, hazard class 1 – in the air of the working area and 0,0002 mg/L, the limiting hazard indicator – sanitary-toxicological, hazard class 1 – in the water.

Introduction. The nutrition of the Nenets in the Arctic zone of Western Siberia is mainly based on traditional products (raw (thermally unprocessed) local fish and venison), which is the most important factor of survival in the Arctic. Storing up food products for an extended period is not relevant for the Nenets. Climate change and industrial development in the Arctic primarily affect the seasonality of consumption. Changing the calendar of fish and venison harvesting leads to greater use of imported and canned local food, increasing the length of the periods when local food completely disappears from the diet of the Nenets. Material and methods. During the expeditions to the national villages of the Yamal-Nenets Autonomous Okrug, cross-sectional screening studies were performed, in which 985 Nenets people took part. Nutritional analysis was conducted using the questionnaire method based on an album of portions and dishes. Retrospective information was collected on the seasonality of consumption of reindeer products and local fisheries (the length of the period when unserved fish and venison are available). Results. The consumption of reindeer and river fishery products is seasonal. The duration of the season of venison consumption was from 150±14.0 to 180±21.0, and raw fish - from 120±14.0 to 200±21.0 days. Despite the high level of consuming reindeer products per season, the average annual consumption of venison by Nenets in the Arctic zone of Western Siberia was 240 g/day/person that is less than in the central regions of the Russian Federation and industrially developed countries. In the studied area, the average annual consumption of fish (171.5 g/day/person) is three times higher than the average consumption in the Russian Federation. However, increased consumption of traditional food is typically only during the season of fishing or slaughtering reindeer. The average annual consumption reduced; during the off-season, the share of easily digestible carbohydrates in the diet increased. Conclusion. The creation of fish and venison stocks in villages and their year-round sale to the population is a necessary step in ensuring the food security of the Nenets people.

Article is devoted quality, production and use of prewilted silage as a best kind of ensilage forage. In a review the forage names are considered. According to the theory of operationalism in 60s years of last century there was introduced a term “haylage”, and in 2010 and 2014 in Belarus (СТБ 1223), and then in the Russian Federation (ГОСТ Р 55986) the term “prewilted silage”. In Germany the prewilted silage (“Spitzensilage”, “Topsilage”) is considerd as a main kind of forage for cows, yielding 10000 L milk pro year. Now the annual volume of prewilted silage production in the Russian Federation exceeds 10 million tons. In some books published last years the information on a chemical composition and nutritive value of prewilted silage produced in the Vologda region and Udmurtiya Republic is reported. Mainly the article is devoted analysis of these data, examples of different quality prewilted silage are given, progressive methods for preparation of a highly nourishing forage are recommended. Foreign and domestic prices on fodder analyses are pointed out. It is recommended to improve system of a forage quality evaluation and use in an animal feeding formula.

The review of soil types prevailing in Western Siberia of the Russian Federation is presented. The compositions and physical and mechanical properties of soils are analyzed. Special attention is paid to loess subsidence soils. The problem of obtaining a homogeneous cement-ground mixture is formulated and set. The technological scheme of production of cement-ground piles of foundations of buildings and structures by drilling-mixing method with mechanical activation is considered. Considers methods of strengthening the loess subsidence of soils. Methods for studying the properties of cement-based piles of foundations of buildings and structures are formulated. A multi-factor experiment was conducted to evaluate the parameters that affect the properties of cement-based piles. Based on the research results, conclusions and recommendations are formulated.

Recently, more and more people are paying attention to healthy lifestyle, including nutrition, giving preference to natural products. One of these products is honey. The chemical composition of honey is represented by a large number of nutrients: easily digestible carbohydrates, amino acids, enzymes, minerals, vitamins, organic acids, causing its nutritional, dietary¬, and medicinal properties. In the article, the authors analyzed the state of honey production in the country, reflected the share of imports in the market and the share of exports in production, the main factors affecting the honey market are investigated. Based on the results of studies of honey from different regions of the Russian Federation and the requirements of international legislation on product safety, the authors have developed proposals to improve the competitiveness of hive products, both in domestic and foreign markets.

The development of geothermal energy in combination with other renewable energy sources (the sun, the wind) will help to solve the problem of heat supply and electrification in near high-rise construction zones of the country, especially in sparsely populated parts, where centralized energy and heat supply is economically unacceptable, and will improve the ecological situation. The aim of the research is to analyze the geothermal resources of the main aquifers in Western Siberia and to develop recommendations for further study and use of heat and power resources of this territory. The article gives retrospective of state research programs and potential use of hydrothermal resources of administrative units geographically entering the territory under consideration. It is noted that by now such programs have been curtailed for various reasons, although there are examples of their successful and effective use in various fields of industry and agriculture. According to the decision of the Supreme Ecological Council of the State Duma Committee of the Russian Federation adopted in 2014 on the beginning of the development of federal targeted programs for the use of heat power water as a source of electricity and heat supply, the Ministry of Natural Resources and Ecology of the Russian Federation made proposals for further research and use of hydrothermal waters in Western Siberia. Implementation of the programs proposed by the authors, alongside with other positive aspects, will solve the problems of heat supply in remote territories and improve the environmental situation in the region.
