Ecology and Environmental Aspects of “Makmalzoloto” Gold Mining Area in Kyrgyzstan

Nazgül İMANBERDİYEVA

This investigation enlightens the original data on the ecological situation of Makmal Valley and neighboring villages Makmal and Chetbulak Toguz-Toro in “Makmalzoloto” gold mining area in Kyrgyzstan. The study was undertaken to put forward the possibilities for preservation of rich biodiversity and ecological state in these villages. The area is under pressure from the activities of gold extraction. Even today environmental pollution and high levels of radiation are observed. The extraction activity has seriously damaged and produced a negative impact on pastures, livestock, as well as biodive ...Более

Assessment of Some Nutrient Contents and Heavy Metal Accumulation in Some Wild Edible Mushrooms in Türkiye

Ali ASLAN

In this study, it was aimed to identify mushrooms gathered from two different regions and localities of Türkiye and to determine their heavy metal and nutrient contents. Four of the mushrooms (Coprinus comatus (O.F. Müll.) Pers, Cantharellus cibarius Fr., Pleurotus ostreatus (Jacq.) P. Kumm. and Lactarius glyciosmus (Fr.) Fr.) from nearby settlements, while the others (Hydnum repandum L., Pleurotus eryngii (DC.) Quél and Lactarius delicious (L.) Gray)) were collected from rural areas. All species have known and consume by local peoples. All identified species were given along with their trophi ...Более

Assessment of Cd-induced genotoxic damage in Urtica pilulifera L. using RAPD-PCR analysis

İlhan DOĞAN

Plants can be used as biological indicators in assessing the damage done by bioaccumulation of heavy metals and their negative impact on the environment. In the present research, Roman nettle (Urtica pilulifera L.) was employed as a bioindicator for cadmium (Cd) pollution. The comparisons between unexposed and exposed plant samples revealed inhibition of the root growth (∼25.96% and ∼45.92% after treatment with 100 and 200 µmol/L Cd concentrations, respectively), reduction in the total soluble protein quantities (∼53.92% and ∼66.29% after treatment with 100 and 200 µmol/L Cd concentrations, re ...Более

Trace metal levels in edible wild fungi

Zeki SEVEROĞLU

Metal levels (cadmium, cobalt, chromium, copper, iron, nickel, lead and zinc) of seventeen different edible wild fungi species (Agaricus campestris, Calocybe gambosa, Coprinus comatus, Hericium coralloides, Hydnum repandum, H. repandum var. rufescens, Lactarius deliciosus, L. salminocolor, Macrolepiota procera, Pleurotus ostreatus, P. ostreatus var. columbinus, Ramaria aurea, R. stricta, Rhizopogon luteolus, Sparassis crispa, Suillus bovinus, Tricholoma terreum) growing in Bolu-Turkey were measured by inductively coupled plasma optical emission spectrocopy. The obtained data were analyzed with ...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

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

Lemna minor, a hyperaccumulator shows elevated levels of Cd accumulation and genomic template stability in binary application of Cd and Ni: a physiological and genetic approach

İbrahim İlker ÖZYİĞİT

In this study, to determine whether having potential to be used as hyperaccumulator for Cd and Ni, numerous experiments were designed for conducting assessments for physiological and genotoxic changes along with defining possible alterations on mineral nutrient status of Lemna minor L. by applying Cd-Ni binary treatments (0, 100, 200 and 400 mu M). Our study revealed that there were increases in the concentrations of B, Cr, Fe, K, Mg, and Mn whereas decreases were noticed in the concentrations of Na and Zn and the levels of Ca were inversely proportional to Cd-Ni applications showing tendency ...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

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

Phytoremediation using genetically engineered plants to remove metals: a review

İbrahim İlker ÖZYİĞİT | Hasan CAN

Contamination by heavy metals including As, Cd, Co, Cu, Fe, Hg, Mn, Ni and Zn in agricultural fields is a global safety issue. Indeed, excessive accumulations of metals have detrimental effects on life by altering cell components such as lipids, proteins, enzymes and DNA. Phytoremediation appears as a solution to remove metals from contaminated sites, yet metal uptake is usually low in most common plants. Therefore, genetically engineered plants have been designed for higher efficiency of metal accumulation. Here, we review metal phytoremediation by genetically engineered plants with focus on ...Более
