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 ...Более

Cadmium-induced physiological and genotoxic alterations in Bryophyllum daigremontianum

Zeki SEVEROĞLU

When evaluating the negative impacts of heavy metals in the environment, plants can be used as biological indicators in assessing damage done by bio-accumulation of heavy metals. For detecting the genotoxic effects of heavy metals, the RAPD-PCR technique is applied in plants. In this study, Blyophyllum daigremontianum was used as a bio-indicator for Cadmium (Cd) pollution. B. daigremontianum plantlets were obtained from bulbiliferous spurs. They were grown singly in standard pots and each of the experimental groups of 5 replicates were watered daily with Hoagland solution (20 ml) containing 0, ...Более

Ecological Assessment of Technogenically Disturbed Soils of the Mountain Ecosystems of Kyrgyz Republic Based on the TRIAD Method

Nurzat TOTUBAYEVA | Kanatbek KOCOBAYEV | Aygül USUBALİYEVA | Ciyde TOKPAEVA

Comprehensive studies of soil contamination were performed in the area of settlement Kichi-Kemin (Kyrgyz Republic). Soils of the Kyrgyz Republic are exposed to waste (tailings) of many industrial enterprises of the mining industry not far from the village of A k-Tuz, located 145 km from the capital of Kyrgyz Republic, Bishkek, at an altitude of 2300 m above sea level. It is noted that 4.17 million tons of radioactive waste from one of the enterprises were once disposed of at four tailings in the Kichi-Kemin Valley. The main waste elements are radioactive thorium, heavy metals such as cadmium, ...Более

СТЕПЕНЬ АККУМУЛЯЦИИ ТЯЖЕЛЫХ МЕТАЛЛОВ В НЕКОТОРЫХ ВИДАХ МАКРОМИЦЕТОВ КЫРГЫЗСТАНА

Nazgül İMANBERDİYEVA

В статье представлены результаты работы по выявлению содержания тяжелых металлов в некоторых видах макромицетов, произрастающих на территории г. Бишкека, в различных по уровню техногенного загрязнения участках. Тяжелые металлы оказывают повреждающее действие на разных структурных уровнях организма и трудно выводятся, поэтому актуальной проблемой является поиск эффективных энтеросорбентов, способных снизить их аккумуляцию в организме человека. Такими свойствами обладают сорбенты из природных продуктов, среди которых особое место занимает полисахарид хитин, благодаря таким его уникальным свойств ...Более

Оценка безопасности рыб, обитающих в водоемах Кыргызской Республики

Aygül USUBALİYEVA

В работе приведены результаты исследования содержания тяжелых металлов (Cu, Pb, Cd, Hg) в мышечной ткани, кожице и костях рыб серебряного карася (Carassius auratus gibelio) и сазана (Cyprinus carpio), обитающих в водоемах Чуйской области и употребляемых в пищу. Выявлено, что концентрация тяжелых металлов в рыбах различается в зависимости от вида рыб из разных водоемов. Результаты анализа показали, что ртуть накапливается, как правило, в больших концентрациях в мышцах рыб (0,083 мкг/г), чем в кожице и костях (0,002 мкг/г). Также обнаружено максимальное содержание свинца в костях рыбы карась 1,0 ...Более

Assessment on phytoplankton composition and heavy metal pollution in a drinking water resource: Lake Terkos (Istanbul, Turkey)

İbrahim İlker ÖZYİĞİT

n this study, the level of water pollution in Lake Terkos, one of the important drinking water resources of Istanbul Metropolitan, was examined by determining the phytoplankton distribution, some physicochemical parameters, nutrients and heavy metal concentrations. For this purpose, samples were collected from eight sampling stations in March and September from the surface water. 34 taxa, from 8 divisions were categorized as Bacillariophyta (17), Charophyta (2), Chlorophyta (5), Cryptophyta (1), Cyanobacteria (5), Euglenozoa (2), Miozoa (1) and Ochrophyta (1). The habitat of blue-green algae A ...Более

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 ...Более

Using the Turkish Red Pine Tree to Monitor Heavy Metal Pollution

İbrahim İlker ÖZYİĞİT

Turkish red pine is an evergreen tree species widely distributed in the Aegean and Mediterranean regions in Turkey. In the present work, the heavy metal pollution level in Istanbul was investigated using Turkish red pine as a biomonitor. For determining heavy metal concentrations (Cd, Co, Cr, Mn, Ni and Pb) in leaf (unwashed and washed) and bark samples of Turkish red pine and its co-located soil samples we used ICP-OES. Additionally, particulate matter profiles of the research areas were investigated. The samples were collected from 5 different localities: 4 from the Bosporus region (Yildiz G ...Более
