The method of laser induced fluorescence (LIF) and a small-sized laser spectrometer are designed to monitor of the dissolved oil products pollution of underwater areas and to assess the impact of pollution on the phytoplankton community state. The excitation technique of the sea water LIF was experimentally tested to simultaneously measure the concentration of chlorophyll A, the specific reproduction of dissolved organic matter by phytoplankton cells, and the concentration of oil products dissolved in sea water. It has been experimentally shown that to implement this technique, it is necessary to carry out the excitation of the LIF by two wavelength radiation. To measure the concentration of chlorophyll A and the specific reproduction of dissolved organic matter (DOM), it is necessary to use excitation by radiation in the green region of the spectrum (532 nm in this work). To measure the concentration of dissolved petroleum products in sea water, it is necessary to use UV radiation (278 nm in this work). The results of tests of the spectrometer under laboratory conditions on sea water samples containing phytoplankton cells and solutions of petroleum products are described. The results of the work create a methodological and software-hardware basis for carrying out the mission of ecological monitoring of underwater areas with the simultaneous solution of the problem of detecting oil pollution and assessing its impact on the phytoplankton community.","PeriodicalId":190056,"journal":{"name":"RUDN Journal of Ecology and Life Safety","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121473098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current state of the urban environment was assessed by a set of morphostructural, physico-chemical and toxicological indicators of tree plantations (pine, larch, birch) and gray forest soils - the main habitat-forming components. For the first time on the basis of the obtained data and assessment of ecosystem functions of soil cover and tree plantations the results of studies on purification of atmospheric air and preservation of phyto-pedocenoses in the urban environment are presented. The study of biogeochemical redistribution of flows of aerotechnogenic pollutants in urban forests revealed the degree of manifestation of the most important ecosystem function of the soil cover - the ability to accumulate and detoxify man-made pollutants and the function of woody plants - the ability to clean atmospheric air by accumulating toxicants in the needles and leaves.

In addition, it is important for the preservation of all unique ecosystem of the protected area. The decrease in the level of lakes during the 20th century, combined with their pollution, repeatedly led to their eutrophication and fish kill. The aim of the work was to establish the relationship the water level in the Kosinsky lakes (during the observation period) the amount of precipitation and economic activities related to drainage. The null hypothesis: the reason for the modern swallowing of the Svyatoe Lake is not so much climate change as anthropogenic activity. The article presents data on fluctuations in the level of lake-type water bodies in the Kosino-Ukhtomsky district of Moscow, for the period 1924-2021, and an assessment of the impact of them modern anthropogenic processes. The work is based on the results of both the authors’ own field research (geodetic survey in the Kosnsky Three Lakes area in 2006-2021) and archival data from the Kosinskaya biological station and other organizations. It shown that the changing level of the Holy Lake in the last decade cannot explained only by meteorological phenomena (precipitation). The significant role of hydrotechnical measures in regulating the level of lakes Beloe and Chernoye has confirmed.","PeriodicalId":190056,"journal":{"name":"RUDN Journal of Ecology and Life Safety","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134256774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is necessary to pay a special attention on the first soil salination of arid regions, as arid climate leads to the active salt accumulation in the upper rooting soil horizons and gives rise to withdrawal of large land areas from economic turnover. The purpose of the this work is defining of the watersoluble salts specific features in soils of the river Volga delta upper level natural boundaries under the influence of natural factors. Botanic natural sanctuary “Svinoroiny meadow (Meshkovsky)” was chosen as a research object, associated with the new Caspian coastal plain within distribution of the river Volga delta Baer knoll landscape. Water extract ions analysis and soil solution toxicity calculation on the area were carried out from 1979 till 2020. It was revealed that dynamics direction of salination types are defined by the ascent of water predominanceon over descending on the area in the conditions of the territory exudative water regime. Salination increase to a great extent depends on the great volumes of spring-summer floods and appropriate ground water level rise, area desalination is defined by atmospheric precipitations quantity.","PeriodicalId":190056,"journal":{"name":"RUDN Journal of Ecology and Life Safety","volume":"726 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113982207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We estimated the water budget of a Ramsar site, La Tembladera wetland, for a two-year period (2018-2019) by using the water balance method. The evapotranspiration was calculated using the Thornthwaite method and the runoff was estimated using the Curve Number method. The proposed water balance model showed that the major inflows to the wetland were the San Agustín and Bellavista canals, and Estero Pinto, about 92.9% (2018) and 90.5% (2019) of the total inflows. The runoff and wastewater flows represented the minor inflows. The runoff was 0.003% in 2018 and 0.004% in 2019, whereas the wastewater volume accounted for 0.05% of all inflows in both years. The actual evapotranspiration was the major outflow in both years, being 67.1% (2018) and 73.6% (2019) of the total outflows. On the other hand, the irrigation canal was the minor outflow, 32.9% in 2018 and 26.4% in 2019. Therefore, La Tembladera wetland hydrology is mostly linked to the canals system and climate conditions, precipitation and actual evapotranspiration. Our findings could be the basis for further research and developing plans in order to rationally manage and protect this wetland of international importance.","PeriodicalId":190056,"journal":{"name":"RUDN Journal of Ecology and Life Safety","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130010931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
