In this study, the concentrations of Zn and Cr in downstream waters from Uzunçayır Dam (Tunceli, Turkey) were monitored during spring (March, April, May) and summer (June, July, August) season. Zinc and Cr concentrations in surface water samples were detected using the ICP-MS device. According to the data obtained the lowest Zn and Cr concentrations in the spring season were 65.43±3.2 μg/L in M...
In the present study, impact of different irrigation sources on metals (Cd, Pb, Zn, Cr, Cu, Ni and Fe) uptake by Tomato (Solanum lycopersicum), Onion (Allium cepa L.), Pepper (Capsicum annuum L.) and Beans (Phaseolus vulgaris L.) grown in Nevsehir Province were determined using ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy). Heavy metal concentrations in vegetables irrigated...
in the industrial area of elefsis, greece, aerosol samples from the atmosphere were collected using a stacked filter unit sampler, which separates the airborne particulate matter into coarse (pm2.5-10) and fine (pm2.5) size fractions. the samples collected during the period january 2005 to march 2006, were analyzed by anodic stripping voltammetry (asv) and inductively coupled plasma atomic emis...
Human saliva offers a unique noninvasive approach for populational study. Purposes of this study were to investigate the feasibility of using saliva manganese (Mn) concentration as a biomarker of Mn exposure among career welders and to study the variations of Mn, copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) in saliva as affected by the welding profession. Forty-nine male welders, of whom...
Through analysis of their chemical composition, human teeth may serve as retrospective bioindicators of preand postnatal nutrition and exposures to environmental pollutants. The research presented here explores the agreement of laser ablation ICP-MS and solution ICP-MS analyses aimed at capturing temporal changes in the trace element composition of enamel. Good agreement was found for LA-ICP-MS...
Zinc (Zn) is essential for all life forms, including humans. It is estimated that around two billion people are deficient in their Zn intake. Human dietary Zn intake relies heavily on plants, which in many developing countries consists mainly of cereals. The inner part of cereal grain, the endosperm, is the part that is eaten after milling but contains only a quarter of the total grain Zn. Here...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
the southeastern part of turkey is quite rich, fertile and mature in terms of hydrocarbonseepages. while the use of the related sources meet the energy demand, it damages the environment and humanhealth. in this study, several geochemical methods were applied to analyze the hydrocarbon sepage samplesobtained from seven towns in the province of adiyaman where is very close to the oil production ...
