Impact of Kara-Keche lignite mining on the Kara-Keche River water composition and properties = Влияние разработки Кара-Кечинского буроугольного месторождения на состав и свойства вод реки Кара-Кече

Kanatbek KOCOBAYEV | Nurzat TOTUBAYEVA | Nurzat ŞAYKİYEVA

On the evidence of the earlier research findings, as well as the full-scale and lab-scale test data of 2019–2020, this article describes the ecological situation at Kara-Keche lignite field being developed by five mining companies in the Jumgal district of the Naryn Region in the Kyrgyz Republic. It is found that the field development proceeds with insufficient adherence to legal documents and has a considerable adverse influence on the environment and water bodies. Many large-volume refuse dumps have no isolation from natural water bodies, which ends with acute pollution of the latter. Contam ...Daha fazlası

Sorption characteristics of zeolite and bentonite natural adsorbents modified complex

Zarlık MAYMEKOV

The main objective of our study is to obtain a complex compound from natural adsorbents to purify wastewater with simultaneous sorption of chemical and microbiological substances contained therein, which contribute to disinfection and softening of water, increasing the degree of treated water saturation with calcium, magnesium salts and trace elements, while not requiring the use of sophisticated equipment. The technical result is to create a complex of adsorbents with the sorbing ability of chemical and microbiological pollution, disinfecting and softening water, enriching it with calcium ion ...Daha fazlası

Mining- Associated environmental problems in the Kyrgyz Republic = Геоэкологические проблемы, связанные с деятельностью горнодобывающих предприятий Кыргызской Республики

Kanatbek KOCOBAYEV | Nurzat TOTUBAYEVA

Рассмотрены актуальные геоэкологические проблемы, связанные с деятельностью горнодобывающих предприятий Кыргызской Республики. Авторами сделан вывод, что почти все горнодобывающие предприятия оказывают опасное экологическое воздействие на окружающую среду. Необходимо уделять пристальное внимание не только хвостохранилищам, но и отвалам пустых пород, так как они могут иметь громадные объемы и служить опасными источниками химического загрязнения вод в течение длительного времени после закрытия предприятий. - Ключевые слова: Кыргызская Республика, горнодобывающие предприятия, геоэкологические пр ...Daha fazlası

Removal of arsenic in groundwater from western Anatolia, Turkey using an electrocoagulation reactor with different types of iron anodes

Mehmet KOBYA | Mustafa DOLAZ

Electrocoagulation (EC) is a significantly efficient method for As removal from waters and received considerable attention recently. In this study, the natural groundwater (GW) samples containing As concentrations of GW-1: 538.8 mu g L-1, GW-2: 1132.1 mu g L-1, and GW-3: 52, 000 mu g L-1 were obtained from different provinces and treated by EC process using different iron anodes (plate, ball, and scrap). To achieve drinking water As standard (10 mu g L-1), the operational time, applied current, and As removal optimization for all anode types were studied. At applied current of 0.025 A, the As ...Daha fazlası

RECOVERING OF INDIGO DYE FROM DENIM WASTEWATER WITH H2O2 IN THE PRESENCE OF KI CATALYST

Mustafa DOLAZ

Today, the textile industry, which is rapidly developing and growing in proportion to the human population, poses serious environmental and health problems in terms of waste. In the world, indigo dyes are widely used in the manufacturing of jeans fabrics especially in textile factories producing cotton fabrics. The overall objective of the present study is to recover indigo dye which is referred to as the pollutant released into the wastewater and to assess the removal of color via oxidation. For this purpose, denim wastewater containing solid particles and small size cotton fibers was filtere ...Daha fazlası

A case study performed in Kucukcekmece Lagoon channel/Istanbul, Turkey: how the heavy metal contamination and the seasonal variations on phytoplankton composition influence water quality

İbrahim İlker ÖZYİĞİT

In this work, the experiments related to seasonal variations of phytoplankton composition and heavy metal contamination along with some water quality parameters were carried out throughout the channel, serving as a waterway between Lake Kucukcekmece and the Sea of Marmara. Considered as a Class B wetland, the lake has been stayed within the metropolitan area of Istanbul overtime. The samples from the surface water were taken monthly by using Nansen bottles at 5 sampling sites through the period of March-November. After experimental procedures, a total of 46 taxa were recorded belonging to Baci ...Daha fazlası

A Comparison of Various Ecological Indexes for Environmental Assessment of Vulnerable Mountain Ecosystems

Nurzat TOTUBAYEVA | Kanatbek KOCOBAYEV | Gülbübü KURMANBEKOVA | Ciyde TOKPAEVA

The aim of this work was to compare various ecological indexes to assess the state of urbanized ecosystems of the Issyk-Kul region in the Kyrgyz Republic. Soil samples were analyzed for Pb, Zn, Fe, Cu and Cd using AAS. Heavy metal contamination status was assessed using indexes for enrichment factor, geo accumulation, contamination factor, degree of contamination, pollution load, potential ecological risk and integrated risk using the Triad approach. Results show marked variations of heavy metal concentrations within the study area. The concentrations of heavy metals in soils of Issyk-Kul had ...Daha fazlası

RK PROBABILISTIC HYDROGEOLOGICAL MAP

Kanatbek KOCOBAYEV

Hydrogeological maps are currently one of the most important elements of the image of the hydrogeological situation in both regional and local representation. In accordance with the existing instructions, they are compiled on the basis of t opographic, geological and tectonic maps of various scales based on the results of hydrogeological surveys and reflect the boundaries of the distribution of aquifers and complexes, confined, as a rule, to geological-stratigraphic and tectonic formations and their real manifestations on the ground (sources, wells, drilling wells). In addition to the General ...Daha fazlası
