Biosorption of Cadmium Ions from Aqueous Solution Onto Non‐living Lichen Ramalina fraxinea Biomass
Authors: Tay Turgay , Candan Mehmet , Erdem Murat , Çimen Yasemin , Türk Hayrettin 
Published: March 2009

AbstractLiving lichens are known to accumulate metals across their surface. In this study, the biosorption of cadmium ions (Cd2+) by the lichen Ramalina fraxinea was investigated in aqueous solution in a batch system with respect to pH, contact time, temperature, initial cadmium ion concentration and size of biomass. The adsorption data appear to fit both the Langmuir and Freundlich adsorption models. The maximum adsorption capacity of the lichen R. fraxinea was found to be 7.00 mg/g at pH 6. The kinetic data were analyzed using the pseudo‐first‐order and pseudo‐second‐order equations. Kinetic parameters such as rate constants, equilibrium adsorption capacities and correlation coefficients for each kinetic model were calculated and discussed. The adsorption process of cadmium ions onto the R. fraxinea biomass fitted well the pseudo‐second‐order kinetic model. It appears that R. fraxinea adsorbs cadmium ions moderately compared to some biosorbents.
Turbidity Removal from Wastewaters of Natural Stone Processing by Coagulation/Flocculation Methods
Authors: Ersoy Bahri , Tosun Ismail , Günay Ahmet , Dikmen Sedef 
Published: March 2009

AbstractThe effectiveness of coagulation (at pH values of 6, 7.5, and 9), flocculation (at pH 9), and coagulation plus flocculation (at pH 9) on turbidity removal from natural stone (travertine) processing wastewaters (NSPW) were examined by applying classical sedimentation tests. FeCl3·6 H2O, AlCl3, and Al2(SO4)3·16 H2O were used as coagulants and a polyacrylamide based anionic polymer was used as the flocculant. In this way, it was found that the coagulation method alone was not sufficient to purify NSPW, whereas flocculation and coagulation plus flocculation methods provided superior purification. Among the coagulants used, AlCl3 gave the best result in terms of turbidity removal by coagulation from NSPW at pH 6 and 9, whereas the turbidity removal performances of the three coagulants were almost identical at pH 7.5. In addition, relatively low pH (i. e., pH 6) improved the purification performance of all coagulants. During coagulation of NSPW at pH 6, a charge neutralization mechanism played a decisive role in turbidity removal. However, in neutral (pH 7.5) and slightly basic (pH 9) media, a sweep coagulation mechanism was predominant. For flocculation of NSPW, the basic mechanism comprised of polymer bridging.
The Potential of Eleocharis acicularis for Phytoremediation: Case Study at an Abandoned Mine Site
Authors: Hoang Ha Nguyen Thi , Sakakibara Masayuki , Sano Sakae , Hori Rie S. , Sera Koichiro 
Published: March 2009

AbstractPhytoremediation, a plant‐based and cost‐effective technology for the cleanup of contaminated soil and water, is receiving increasing attention. In this study, the aquatic macrophyte Eleocharis acicularis was examined for its ability to take up multiple heavy metals and its potential application for phytoremediation at an abandoned mining area in Hokkaido, Japan. Elemental concentrations were measured in samples of E. acicularis, water, and soil collected from areas of mine tailing and drainage. The results reveal that Pb, Fe, Cr, Cu, Ni, and Mn accumulation in the plants increased over the course of the experiment, exceeding their initial concentrations by factors of 930, 430, 60, 25, 10, and 6, respectively. The highest concentrations of Fe, Pb, Zn, Mn, Cr, Cu, and Ni within the plants were 59500, 1120, 964, 388, 265, 235, and 47.4 mg/kg dry wt., respectively, for plants growing in mine drainage after 11 months of the experiment. These results indicate that E. acicularis is a hyperaccumulator of Pb. We also found high Si concentrations in E. acicularis (2.08%). It is likely that heavy metals exist in opal‐A within cells of the plant. The bioconcentration factors (BCF: ratio of metal concentration in the plant shoots to that in the soil) obtained for Cr, Cu, Zn, Ni, Mn, and Pb were 3.27, 1.65, 1.29, 1.26, 1.11, and 0.82, respectively. The existence of heavy metals as sulphides is thought to have restricted the metal‐uptake efficiency of E. acicularis at the mine site. The results of this study indicate that E. acicularis shows great potential in the phytoremediation of mine tailing and drainage rich in heavy metals.

AbstractBACKGROUND:Children who receive high‐dose radiotherapy to the hypothalamic‐pituitary (H‐P) axis may be at risk for both early and late puberty. To the authors' knowledge, data regarding the risk of altered timing of menarche after higher dose radiotherapy (RT), as used in the treatment of central nervous system (CNS) tumors, are limited.METHODS:The authors evaluated 235 female survivors of CNS tumors, diagnosed between 1970 and 1986, and >1000 sibling controls who were participants in the Childhood Cancer Survivor Study, and provided self‐reported data concerning age at menarche.RESULTS:Survivors of CNS tumors were more likely to have onset of menarche before age 10 years compared with their siblings (11.9% vs 1.0%) (odds ratio [OR], 14.1; 95% confidence interval [95% CI], 7.0‐30.9). Of the 138 survivors who received RT to the H‐P axis, 20 (14.5%) had onset of menarche before age 10 years, compared with 4.3% of those who did not receive RT (OR, 3.8; 95% CI, 1.2‐16.5). Age ≤4 years at the time of diagnosis was associated with an increased risk (OR, 4.0; 95% CI, 1.7‐10.0) of early menarche. In addition, survivors of CNS tumors were more likely than siblings to have onset of menarche after age 16 years (10.6% vs 1.9%) (OR, 6.6; 95% CI, 3.4‐11.4). Doses of RT to the H‐P axis >50 gray OR, 9.0; 95% CI, 2.3‐59.5) and spinal RT conferred an increased risk of late menarche, as did older age (>10 years) at the time of diagnosis (OR, 3.0; 95% CI, 1.3‐7.0).CONCLUSIONS:Survivors of CNS tumors are at a significantly increased risk of both early and late menarche associated with RT exposure and age at treatment.

Pattern of long‐term sensorimotor recovery following intrastriatal and ‐accumbens DA micrografts in a rat model of Parkinson's disease

Published: March 2009

AbstractThe functional restorative capacity of fetal dopaminergic (DA) transplants is governed by a number of critical parameters including graft location, survival of DA neurons, and transplantation technique. In addition, there is an ongoing controversy whether “too much” or “too little” survival of DA neurons is responsible for the incomplete functional recovery observed in some transplanted Parkinson's disease (PD) patients. Here we investigated two implantation sites, the nucleus accumbens (NAc) and the caudate‐putamen unit (CPU), and two different graft distributions within the CPU, i.e., two 0.75 μL deposits (CPU‐2) versus six 0.25 μL deposits (CPU‐6) in a rat model of PD. Grafts were derived from E14 rat ventral mesencephalon and the long‐term functional outcome was evaluated with a wide range of complex‐sensorimotor behavioral tests. The data show that forelimb stepping, balancing behavior, and skilled forelimb reaching behavior was more restored in CPU‐6‐grafted animals as compared to CPU‐2 animals, although the number surviving dopaminergic neurons and dopamine release were similar in the two groups. Furthermore, a correlation analysis revealed a number of inverse relationships between the rate of DA neuron survival and sensorimotor performances, e.g., for skilled forelimb use. DA grafts placed into the NAc induced a partial recovery in drug‐induced rotation tests but failed to restore any of the other sensorimotor behaviors tested. Taken together, these data have important implications both for a better understanding of the complex functional graft–host interactions as well as for the further optimization of clinical neural transplantation strategies in neurodegenerative diseases.
