Functions and Toxicity of Nickel in Plants: Recent Advances and Future Prospects
Authors: Chen Cuiyun , Huang Dejun , Liu Jianquan 
Published: April 2009

AbstractNickel is an essential nutrient for plants. However, the amount of Ni required for normal growth of plants is very low. Hence, with the level of Ni pollution in the environment increasing, it is essential to understand the functional roles and toxic effects of Ni in plants. We briefly review advances in relevant research over the past 20 years. Based on the available data, two new indirect pathways of Ni toxicity in plants are proposed. These are (i) interference with other essential metal ions and (ii) induction of oxidative stress. Research should focus on these mechanisms at the protein and molecular levels. Further research should also be directed at plant species that are capable of accumulating Ni at high concentration, so‐called hyperaccumulators. Such species can provide model systems to study the mechanisms of Ni tolerance and can also be used for phytoremediation by removing nickel from polluted environment.
Stepwise Frontal Analysis to Derive Equilibrium Sorption Data for Copper and Aniline on Functionalized Sporopollenin
Authors: Gezici Orhan , Ayar Ahmet 
Published: April 2009

AbstractA dynamic method called stepwise frontal analysis (SFA) was used to derive equilibrium sorption data of copper and aniline on a carboxylated diaminoethane sporopollenin (CDAE‐S) solid phase. The derived data was modeled on the basis of some common adsorption isotherms, and the importance of Scatchard plot analysis in isotherm modeling was emphasized. In light of the applied isotherm models, the role of aminocarboxylic acid functionalities in the sorption of each chemical species was discussed in terms of specific and nonspecific binding.
Organochlorine Pesticides in Urban Air: Concentrations, Sources, Seasonal Trends and Correlation with Meteorological Parameters
Authors: Ozcan Senar , Aydin Mehmet Emin 
Published: April 2009

AbstractThe concentrations of organochlorine pesticides (OCPs) in both the gas and particulate phases of urban air samples were determined. The samples were collected between August 2006 and May 2007 at four different locations in Konya, Turkey. OCPs were analyzed by gas chromatography with micro electron capture detection (GC/μ‐ECD). The average total (gas + particulate) concentrations of OCPs were determined to be between 809 and 6309 pg/m3. The highest OCP levels were found in autumn. Total hexachlorocyclohexane (HCH, sum of α, β, γ, δ‐HCH), total DDT's (sum ofp,pi‐DDT,p,pi‐DDD andp,pi‐DDE) and endosulfan compounds (sum of endosulfan I, endosulfan II and endosulfan sulfate) were about 43, 25 and 17% of total OCPs, respectively. OCPs were predominantly detected in the particulate phase. Correlations were observed between OCP concentration and temperature, relative humidity, wind speed and Total Suspended Particulate, PM10, but the variation between meteorological parameters with OCP concentrations could not be explained completely. Despite banned/restricted use in Turkey, all the OCPs were found in urban air.p,pi‐DDT/p,pi‐DDE ratios were above 11 which is an indication of current use of DDT compounds. Therefore, it could be suggested that Konya is an actively contributing region to organochlorine pesticides pollutants in Turkey.
Preconcentration and Determination of Zinc and Lead Ions by a Combination of Cloud Point Extraction and Flame Atomic Absorption Spectrometry
Authors: Ghaedi M. , Tavallali H. , Shokrollahi A. , Zahedi M. , Niknam K. , Soylak M. 
Published: April 2009

AbstractThe phase‐separation phenomenon of non‐ionic surfactants occurring in aqueous solution was used for the extraction of lead(II) and zinc(II). After complexation with 3‐[(4‐bromophenyl) (1‐H‐inden‐3‐yl)methyl]‐1 H‐indene (BPIMI), the analytes were quantitatively extracted to a phase rich in Triton X‐114 after centrifugation. Methanol acidified with 1 mol/L HNO3 was added to the surfactant rich phase prior to its analysis by flame atomic absorption spectrometry (FAAS). The concentration of bis((1H‐benzo [d] imidazol‐2yl)ethyl)sulfane, Triton X‐114, pH and amount of surfactant were all optimized. Detection limits (3 SDb/m) of 2.5 and 1.6 ng/mL for Pb2+ and Zn2+ along with preconcentration factors of 30 and an enrichment factor of 32 and 48 for Pb2+ and Zn2+ ions were obtained, respectively. The proposed cloud point extraction was been successfully applied for the determination of these ions in real samples with complicated matrices such as food and soil samples, with high efficiency.
Statistical Optimization of Process Parameters for Cr (VI) Biosorption onto Mixed Cultures of Pseudomonas aeruginosa and Bacillus subtilis
Authors: Tarangini K. , Kumar Arvind , Satpathy G. R. , Sangal Vikas Kumar 
Published: April 2009

AbstractIn the present study, response surface methodology (RSM) was employed to investigate the effects of different operating conditions on the removal of hexavalent chromium (Cr (VI)) onto mixed cultures of Pseudomonas aeruginosa and Bacillus subtilis (MCOPAABS) using biosorption processes. Box‐Behnken design (BBD) was used for optimization of the biosorption process and to evaluate the effects and interactions of the process variables, i. e., biomass concentration, pH, temperature and contact time on the removal of Cr (VI). A synthetic aqueous solution with a Cr (VI) concentration of 10 mg/L was used in the experimental study as a fixed input variable. The optimum conditions for maximum uptake (1.44 mg/g) of Cr (VI) onto the biosorbent were established as 0.5 g/L biosorbent dosage, pH 2 for the aqueous solution, 32°C temperature and 23 min contact time.
Determination of Chromium, Cadmium and Manganese in Water and Fish Samples After Preconcentration Using Penicillium digitatum Immobilized on Pumice Stone
Authors: Baytak Sitki , Türker A. Rehber 
Published: April 2009

AbstractThis study presents a procedure for preconcentration of Cr(III), Cd(II) and Mn(II) from water and biological samples using Penicillium digitatum immobilized on pumice stone. Optimum conditions such as pH, flow rate were evaluated. The recoveries of Cr(III), Cd(II) and Mn(II) under optimum conditions were found to be 98 ± 2%, 100 ± 2%, and 97 ± 2%, respectively, at a 95% confidence level. Detection limits were 2.0, 1.6 and 1.5 ng/mL for Cr(III), Cd(II) and Mn(II), respectively. The proposed procedure was successfully applied for the determination of chromium, cadmium and manganese in dam water, spring water and fish (Carp) samples. The accuracy was evaluated through the analysis of the certified standard reference fish tissue samples (IAEA‐407) and spiked fish and water samples.
Organophosphorus Flame Retardants and Plasticizers in Rain and Snow from Middle Germany
Authors: Regnery Julia , Püttmann Wilhelm 
Published: April 2009

AbstractThe role of precipitation as an important source of, and entry pathway for, organophosphates (OPs) into the aquatic environment was investigated. Rainwater and snow samples (53 and 43, respectively) collected between November 2007 and April 2008 from urban and remote areas of middle Germany were analyzed for OPs by gas chromatography‐mass spectrometry (GC‐MS) after solid phase extraction (SPE). The analytes tris(2‐chloroethyl) phosphate (TCEP), tris(2‐chloro‐1‐methylethyl) phosphate (TCPP), tris(1,3‐dichloro‐2‐propyl) phosphate (TDCP), tris(2‐butoxyethyl) phosphate (TBEP), tri‐iso‐butyl phosphate (TiBP), and tri‐n‐butyl phosphate (TnBP) were detected in almost all rain and snow samples. TCPP was the most abundant chlorinated alkyl‐phosphate ester in urban rainwater, with concentrations ranging from 46 to 2659 ng L–1. In general, concentrations of OPs in urban rainwater were 3 to 4 times higher than those at background monitoring stations, e. g., Schmücke and Thuringian Forest. Variable concentrations of chlorinated flame retardants were found in precipitation, but their occurrence was not correlated with air temperature. The results of the study indicate that volatilization of OPs from objects protected by flame retardants, including vehicles and buildings, causes these compounds to reach the aquatic environment via washout from the atmosphere, despite their reported short atmospheric half‐lives (< 24 h).
TOGp regulates microtubule assembly and density during mitosis and contributes to chromosome directional instability
Authors: Cassimeris Lynne , Becker Bret , Carney Bruce 
Published: April 2009

AbstractTOGp, a member of the XMAP215 MAP family, is required for bipolar mitotic spindle assembly. To understand how TOGp contributes to spindle assembly, we examined microtubule dynamics after depleting TOGp by siRNA. Fluorescence recovery after photobleaching of GFP‐tubulin demonstrated that spindle microtubule turnover is slowed two‐fold in the absence of TOGp. Consistent with photobleaching results, microtubule regrowth after washout of the microtubule depolymerizing drug nocodazole was slower at the centrosomes and in the vicinity of mitotic chromatin in cells depleted of TOGp. The slower microtubule turnover is likely due to either nucleation or the transitions of dynamic instability because TOGp depletion did not effect the rate of plus end growth, measured by tracking EB1‐GFP at microtubule ends. In contrast, microtubule regrowth after nocodazole washout was unaffected by prior depletion of TACC3, a centrosomal protein that interacts with TOGp. Kinetochore fibers in both untreated and TOGp‐depleted cells were stable to incubation at 4°C or lysis in buffer containing calcium indicating that stable kinetochore‐microtubule attachments are formed in the absence of TOGp. Depletion of TOGp, but not TACC3, reduced kinetochore oscillations during prometaphase/metaphase. Defects in oscillations are not due simply to multipolarity or loss of centrosome focus in the TOGp‐depleted cells, since kinetochore oscillations appear normal in cells treated with the proteosome inhibitor MG132, which also results in multipolar spindles and centrosome fragmentation. We hypothesize that TOGp is required for chromosome motility as a downstream consequence of reduced microtubule dynamics and/or density. Cell Motil. Cytoskeleton 2009. © 2009 Wiley‐Liss, Inc.
