This study was carried out to evaluate the water quality of selected dam lakes as well as their suitability for agricultural *** dams were selected for water sampling and samples were collected monthly,including during the irrigation season for a period of one year from March to september *** samples were analyzed for temperature,pH,physicochemical parameters such as temperature,pH value,salinity(EC),anions(CO_(3),HCO_(3),CI,sO_(4),P,NO_(3)),cations(Na,K,Ca,Mg,B,NH_(4))and heavy *** irrigation suitability assessment was made using various indices such as sAR(sodium adsorption rate),TDs(total dissolved solids),Na%(sodium percentage),RsC(residual sodium bicarbonate),MAR(magnesium adsorption rate),kr(Kelly ratio),and PI(permeability index).The temperature values of the water samples varied between 5.8℃-25.1℃,pH and EC values changed between 7.51 and 8.46,282,and 1400μs/cm *** water samples were evaluated as C_(2)s_(1) and C_(3)s_(1) irrigation water *** heavy metal contents of the water samples were determined below the limit *** dams were found suitable for irrigation in terms of EC(salinity),sAR(sodium adsorption rate),TDs(total dissolved solids),Na%(sodium percentage),RsC(residual sodium bicarbonate),MAR(magnesium adsorption rate),and kr(Kelly ratio).Water samples were determined as the second class of PI(permeability index).Güllübağdam was not found suitable as irrigation water in terms of EC,Na%,RsC,and kr *** a result,it specifically points to the restrictions on the use of water from the Güllübağdam for irrigation purposes.

Fluid Inclusion studies and Geochemistry of Rare Earth Elements of Hydrothermal Fluorites from Pohrenk,Kirsehir,Central Turkey

引用

Acta Geologica sinica(English Edition) 2001年第1期75卷 59-65页

作者： sükrü KOC Ali RECBER Geology Department Ankara UniversityAnkara 06100Turkey General Directorate of Mineral Research and Exploration Ankara

Fluorite mineralization occurs along fractures and cracks of Middle Eocene and Pliocene limestones and marls in the north and northeast of the P?hrenk region (?i?ekdagi, Kirsehir). Tb/Ca – Tb/La and Y/Ho ratios were obtained from REE contents of fluorites which have revealed that mineralization is of hydrothermal type. Negative Ce anomalies and positive Eu anomalies reflect that hydrothermal solutions once had high oxygen fugacity. Fluid inclusion studies indicate that homogenization temperatures of mineralization varied between 90°C and 200°C, and hydrothermal solutions are composed of NaCl + KCl + MgCl2 + H2O. In addition, salinity measurements show that hydrothermal solutions were mixed with meteoric or rock formation water. Geologic setting, REE geochemistry and fluid inclusion studies suggest that mineralization was deposited from a solution generated by mixing of magmatic and meteoric water under epithermal conditions.

In their research article in Nature in March 2023,Fabio Zani and colleagues reported that high concentrations of the zero-calorie artificial sweetener sucralose affected the proliferation and differentiation of T cells toward interferon-γ-producing subsets,with no effect observed for B cells and myeloid cells.1 The publication has raised high hopes in the lay press on a widely available cure for patients suffering from autoimmune diseases.

Geochemistry of Kestelek Colemanite Deposit, Bursa, Turkey

引用

Journal of Earth science 2017年第1期28卷 63-77页

作者： sükrü Koc Ozge Kavrazh ismail Kocak Faculty of Department of Geological Engineering Ankara University Ankara 06100 Turkey Graduate school of Natural and Applied sciences Ankara University Ankara 06100 Turkey Department of Geological Engineering Bozok University Yozgat 66100 Turkey

The Kestelek borate deposit has been the subject of geological and mineralogical research over the last decades, but major and trace element geochemistry of this deposit was first investigated in the present study. A total of 22 samples collected from surface exposures and different depths of deposit in boreholes（e.g., lower, middle and upper） comprise the material of this study. Major, trace and REE element analyses of samples were conducted with ICP-Ms and ICP-Es methods. The Kestelek borate deposit of Miocene age was formed in playa lakes in an intermountain closed basin which was developed in volcanically and seismically active areas associated with growth faults and grabens affected the whole Anatolia at the beginning of Paleogene. Only colemanite was found as the borate mineral accompanied in lesser amount by calcite, aragonite, smectite, illite, chlorite, corrensite, heulandite and quartz. In colemanite samples, all major elements, except for Ca, show depletion trends with respect to average of earth crust and andesite. For the trace elements, Li, Cs, sb, As, sr and se are characterized by significantly high concentrations. Evaluation of element concentrations and geochemical characteristics reveal that As, Cs, sb and Li are of detrital origin, se together with B and Ca are of non-detrital and sr is indicative of both detrital and non-detrital origin. REE distributions indicate that at least two different depositional regimes prevail in the environment. Corrensite, a clay mineral forming in lake waters, is derived from volcanism. Negative Ce and positive Eu anomalies are indicative of contribution from hydrothermal solutions and fluids.

Pentachlorophenol degradation by Pseudomonas stutzeri CL7 in the secondary sludge of pulp and paper mill

引用

Journal of Environmental sciences 2010年第10期22卷 1608-1612页

作者： santosh kr.Karn s.K.Chakrabarty M.s.Reddy Department of Biotechnology Thapar University Thapar Centre for Industrial Research and Development

A pentachlorophenol （PCP） mineralizing bacterium was isolated from the secondary sludge of pulp and paper mill and identified as Pseudomonas stutzeri strain CL7. This isolate used PCP as its sole source of carbon and energy and was capable of degrading this compound as indicated by stoichiometric release of chloride and biomass formation. P. stutzeri （CL7） was able to mineralize a high concentration of PCP （600 mg/L） than any previously reported Pseudomonad with PCP as sole carbon source. As the concentration of PCP increased from 50 to 600 mg/L, the reduction in the cell growth was observed and the PCP degradation was more than 90% in all studied concentrations. This isolate was able to remove 66.8% of PCP from the secondary sludge of pulp and paper mill when supplemented with 100 mg/L of PCP and grown for two weeks. This study showed that the removal efficiency of PCP by CL7 was found to be very effective and can be used in PCP remediation of pulp paper mill waste in the environment.
