Living in the city is affected by numerous factors, the action of which can cause harm to the human health. One of them is a noise pollution of the living environment by road transport. On the streets with intense traffic, noise levels often exceed the permissible values for the living environment. Various measures can be applied to reduce noise in residential areas, which will promote the extension of the period of active human activity, improve living conditions and increase in life expectancy. One of the most effective noise protection measures (especially in multi-storey buildings) is the use of windows with high soundproofing. There were conducted the studies of noise pollution of residential areas in Dnipro (Dnipropetrovsk). Experimental investigations were performed according to standard methods using modern acoustic measuring instruments. When obtaining data and processing the results there were used a special computer program to build noise maps in 3D (developed in Prydniprovska State Academy of Civil Engineering and Architecture) and methods of mathematical statistics. As a result of the research, a nomograph was constructed to determine the category of windows on different facades for different floors of the building. The nomograph enables to reasonably and quickly decide on the need to use windows with high soundproofing.

The article presents the results of assessing the degree of negative impact of the enterprise LLC Collective fishery "Tihiy okean" on the atmospheric air. The enterprise releases 33 pollutants into the atmosphere. Substances of the first hazard class include: dimethylamine, benzo/a/pyrene. Substances of the second hazard class include: manganese and its compounds, sulfuric acid, hydrogen sulfide, gaseous fluorides, poorly soluble fluorides, phenol, formaldehyde. All other substances belong to 3–4 hazard classes, or are not assigned to any. The work takes into account 23 sources of air pollution at the enterprise, operating at the time of the inventory of them: including 9 — organized, fourteen — unorganized. In order to analyze the compliance of indicators with hygienic standards for the quality of the surface layer of air, according to the content of 23 pollutants in it, was carried out using a unified program — UPRZA Ecolog ver. 3.0. assessment of the magnitude of surface concentrations of these impurities at the border of the sanitary protection zone of the enterprise. The results of the calculations indicate the observance of hygienic standards of atmospheric air quality, taking into account background atmospheric pollution for 23 substances emitted by the sources of the enterprise LLC "Cf" Tihiy okean. Consequently, emission limits are proposed at the level of existing emissions. The development of air protection measures is not required, but it is recommended to use the most environmentally friendly equipment currently available. The purpose of the work is to assess the degree of negative impact of the enterprise LLC Collective fishery "Tihiy okean" on the atmospheric air, determination of the level of air pollution by the enterprise.

Владивостокский государственный университет экономики и сервиса Владивосток. Россия Влияние отвалов металлургического производства на состояние атмосферного воздухаРост производства непосредственно связан с количеством и опасностью образуемых им отходов. При этом общей тенденцией остается следующая закономерность: чем больше образуется отходов, тем они менее опасны. Однако накопленные за десятилетия отходы до сих пор представляют серьезную опасность не только в локальных масштабах. Одним из показателей опасности элементов, входящих в состав отходов, является их индекс технофильности. В данной работе проводится оценка воздействия шлаковых отвалов металлургического производства на состояние атмосферного воздуха в регионе с учетом технофильности элементов, входящих в состав шлака. Цель данного исследования состоит в оценке воздействия шлаковых отвалов металлургического производства на состояние атмосферного воздуха в регионе с учетом технофильности элементов, входящих в состав шлака. Предметом исследования является воздействие шлаковых отвалов на состояние атмосферного воздуха в регионе с учетом технофильности элементов, входящих в состав шлака. Проведенный анализ показал, что элементы, входящие в состав шлаков металлургического производства (производство ферросплавов), обладают относительно невысоким индексом технофильности. Тем не менее, накопление достаточно большого количества отходов, которые постоянно подвергаются процессам выветривания, может представлять собой угрозу не только в локальных масштабах, особенно за счет образования мельчайших аэрозолей, способных распространяться на десятки-тысячи километров. Проведенный расчет интенсивности пыления свидетельствует о величине около 280 г/с, и это только при статическом хранении отходов. В составе такой пыли содержится значительное количество тяжёлых металлов, представляющих значительную угрозу для окружающей среды, а, следовательно, и здоровья населения.Ключевые слова и словосочетания: шлак; окружающая среда; отвалы; металлургическое производство; пыление; тяжелые металлы.Макарова Вера Николаевнаканд. техн. наук, доцент кафедры туризма и экологии;

In the process of interaction of the man with the habitat he is an integral part of the natural environment. To assess the anthropogenic impact upon the environment, living bioindicators are used which have several advantages over chemical methods of environmental assessment. They can respond even to any minor changes and enable to avoid the use of expensive and labor-intensive physical and chemical methods for measuring biological parameters. The assessment of a degree of soil contamination using bioindication, in places of oil products storage and active contamination from motor transport (central city), enables to determine a soil toxicity. Environmental toxicity can be determined by a level of response of the test object used. Reliability of results is confirmed by environmental statistical methods or biometrics. In this study, we obtained data that, taking into account the geographical location of the sampling point, the results demonstrated both a low toxicity of the soil and a stimulating effect of man-made environmental factors upon its state.

The relevance of the topic of the work lies in the consideration of one of the most promising methods of gentle nature management — ecological tourism. Special attention is paid to the state nature reserve "Bureinsky", namely to the assessment of anthropogenic factors that can lead to a decrease in the number of visitors to the reserve. The article describes in detail the technique of "estimation of current capacity" and its practical application on the territory of the ecological trail "At the Sources of Burea" in the State Nature Reserve "Bureinsky". An important sphere of activity in the sustainable development of the state and the development of ecological tourism is the provision and preservation, restoration of the environment in the process of recreational use and minimization of possible negative consequences. The use of this technique allows you to regulate the level of negative anthropogenic impact on the natural environment and create optimal conditions for visiting the reserve in a short time without resorting to the involvement of outside specialists. The article offers a list of the most significant factors of anthropogenic impact, taking into account their weight in the impact on natural territories, based on which the number of visitors to the route under consideration was calculated. The scientific novelty of the study consists in the correction of the method of calculating the recreational capacity to prevent the degradation of the natural environment of hard-to-reach protected natural territories, which will allow the development of ecological tourism in hard-to-reach protected natural territories in the context of sustainable development. The authors consider possible prospects for the development of ecological tourism in the reserve and offer options for the distribution of the flow of tourists, which can contribute to the sustainable development of modern society, in which future generations will inherit from us the world around us with parts of the earth's surface without any changes. The purpose of this article is to calculate the maximum permissible recreational capacity of the trail "At the Sources of Burea" on the territory of the State Nature Reserve "Bureinsky".
