- MakaleAçık Erişim2013Scopus SJRQ4Adsorption of the 2,2-Dichlorovinylphosphate on Raw and Modified Bentonites
Yönten, Vahap; Kubilay, Senol
This study aims to investigate the adsorption of the 2,2-dichlorovinylphosphate (DDVP) on raw and modified bentonite via high pressure liquid chromatography and infrared spectroscopy. The modified bentonites were prepared by adding HNO3 and Na2CO3. The Freundlich adsorption isotherm defines 2,2-dichlorovinylphosphate adsorption in aqueous and aqueous ethanol solutions through raw and modified bentonite. Variables such as temperature, time and pH were observed on 2,2-dichlorovinylphosphate adsorption. Then the capacity for maximum 2,2-dichlorovinylphosphate adsorption was measured on modified bentonite with HNO3 under the conditions of pH 3 and 40 degrees C. The modified bentonite with Na2CO3 clay used in experimental work played a major role on the adsorption of 2,2-dichlorovinylphosphate; thus modified bentonite with Na2CO3 is considered to possess better characteristics than modified bentonite with HNO3 and raw bentonite. The Freundlich isotherms of modified bentonite with Na2CO3 in aqueous-ethanol solution were found to be better than isotherms of aqueous solution for a much better 2,2-dichlorovinylphosphate adsorption.

Demir, V.; Bin-Shafique, S.
Batch studies indicated that low cost native materials such as loam soil, juniper mulch, hardwood mulch, pine mulch and sawdust performed efficiently as media in bioretention cell for removal of copper and lead from stormwater runoff. Juniper mulch performed best in batch studies was used in column studies. Column studies suggested that the presence of phosphate has a pronounced effect on metal immobilization. This is due to the formation of metal phosphates that have extremely low solubility. The remaining metals were adsorbed on bioretention media of the bioretention cell. Breakthrough adsorption and desorption curves for lead and copper were measured in presence and absence of phosphate immobilization. Copper reached a breakthrough curve in around 20 days and lead in 30 days. Column studies showed that in all samples addition of phosphate also decreased the leaching of lead and copper back to aqueous solution consistent with lead and copper immobilization.

In the present study, tensile bond strength between on acrylic resin and a soft liner, molloplast B, was studied. To enhance the bonding capacity between these materials, acrylic resin surface was modified using ethyl methacrylate, iso-butyl methacrylate or tert-butyl methacrylate monomers. The monomers were applied onto the surfaces of methacrylate components for 60, 120 or 180 s and the bond strength values were obtained. The values were statistically compared. Changes on the modified surfaces were investigated by fourier transform infared spectroscopy with attenuated total reflectance (FTIR-ATR). The highest bond strength value was obtained from 120 s treatments with ethyl methacrylate and the lowest value was obtained from 60 s treatments with iso-butyl methacrylate. These high alkyl monomers also had secondary interactions on the acrylic surfaces, evidenced by FTIR-ATR.

This study is aimed to determine the bioaccumulation of copper and zinc in hemolymph of freshwater crayfish (Astacus leptodactylus) fed with zebra mussel (Dreissena polymorpha) collected from Keban Dam Lake. This is the first study on bioaccumulation of Cu and Zn in hemolymph of males and females of A. leptodactylus. The average concentrations of Cu and Zn in the hemolymph samples were found out as 0.54 and 35.07 ppm respectively for male and 0.42 and 15.59 ppm respectively for female control freshwater crayfish. The levels of Zn in the hemolymph of both male and female ones among control and diet groups were statistically significant (P < 0.05). The Cu levels among control and diet groups in female ones were statistically significant (P < 0.05) but not in the male ones (P > 0.05). The results of current study revealed that feed treatment with boiling was not effective at the levels of metal bioaccumulation in hemolymph. It was observed that this metal bioaccumulation is more related with sex differences.

Ince, Muharrem; Yaman, Mehmet
The concentrations and varieties of benzo[a]pyrene were determined in Turkish foodstuffs including grilled meat and chicken samples by high performance liquid chromatography-mass spectrometry (HPLC-MS). The parameters that are thought to affect the response in the HPLC-MS analysis were optimized. The optimized conditions were found to be 0.75 mL min(-1) for flow rate of mobile phase, 45 mu L for injection volume, 55 degrees C for column temperature and 140 V for fragmentor potential. The optimized method was applied for the determination of benzo[a]pyrene concentrations in grilled meat and chicken foods. The obtained concentrations were found in the range of 2.7-8.3 mu g kg(-1) for the normal grilled meat and chicken samples and 72-138 mu g kg(-1) for over-grilled samples. The results showed that the concentrations of benzo[a]pyrene were significantly dependent on the kind of meat and the cooking time and source. The limits of detection and quantitation were found to be 0.7 and 2.33 mu g L-1, respectively.

Yildirim, N. C.; Danabas, D.; Ergin, C.
The potential utility of biomarkers for monitoring both environmental quality and the health of organisms inhabiting polluted ecosystems has received increasing attention during the recent years. In this study. it was aimed to investigate the possible effect of pollution on biochemical parameters of Capoeta trutta captured in two environments with different levels of pollution in Munzur River, Tunceli, Turkey. One of them, hereby named reference site, there is no sewage discharge. Other side is denominated as polluted site is characterized by discharge of domestic sewage. Levels of amylase, alkaline phosphatase, lactate dehydrogenase, high-density lipoprotein cholesterol, cholesterol, albumin, total protein, direct bilirubin, total bilirubin, gamma-glutamyl tranferase, aspartate aminotransferase, alanine aminotransferase, urea, creatinine, glucose, triglycerides and uric acid were checked in blood samples. Plasma biochemical changes showed significantly differences between reference and polluted sites in alkaline phosphatase, lactate dehydrogenase, high-density lipoprotein cholesterol, cholesterol, alanine aminotransferase and glucose values. These results indicate that both domestic waste water and agricultural activities can alter the serum biochemical contents of Copeata trutta fish in Munzur River. Continuous production of pollutants resulting in impaired ability to respond to different environment stress factors and diseases. Present groups of researchers suggest that pollution levels should be monitored regularly.

The aim of this study is to evaluate the protective effect of pomegranate seed extract on cisplatin-induced oxidative stress in rabbits testes. Rabbits were divided into three groups; (i) being control group, (ii) cisplatin group and (iii) cisplatin + pomegranate seed extract group. The level of malondialdehyde and glutathione, the activity of catalase, glutathione peroxidase, were measured in testes tissue of rabbits. Malondialdehyde levels were increased depending on cisplatin. In the case of cisplatin + pomegranate seed extract, malondialdehyde levels were found to be lower than cisplatin group (p < 0.05). In cisplatin group, catalase, glutathione peroxidase activity and glutathione levels were decreased when compared to control but in cisplatin + pomegranate seed extract group, catalase, glutathione peroxidase activity and glutathione levels were found higher than cisplatin group (p < 0.05). The pomegranate seed extract supplementation may play a protective role or decrease the side effects of cisplatin-induced testes toxicity from cancer medicines.

Bayril, T.; Cimen, M.; Tekelioglu, O.
This research was aimed to investigate the biochemical flavour-parameters of milk by machine milking in early lactation period. In the experiment, milk samples from 50 Holstein cows were used. Cows were fed high-energy concentrate diet (140 g crude protein and 10.3 metabolizable energy MJ/d). The data was collected from DIMES Company during July month. The milk fat rates were lower (p < 0.05) for cows in first and second weeks than last week. Cows were shown to be more sensitive to milk fat syndrome for first and second weeks. A decrease in milk fat percentage for summer period (2.3-2.6 %) can directly lead to taste loss. There were statistically no significant differences between the weeks for milk acidity (sH and pH) values during July. The milk acidity values (sH and pH) during July were tolerable for desired taste and favourable for consumer preference.
