A method based on reversed-phase high performance liquid chromatographic separation in combination with spectrophotometric detection was developed for the determination of trace amounts of vanadium(V) as its ternary complex with 2-(8-quinolylazo)-4,5-diphenylimidazole (QAI) and hydrogen peroxide. Spectral and chromatographic behaviors of the ternary complex were investigated. The complex was formed in weekly acidic medium (pH 2.5-4.0) and separated on a Cosmosil 5C8-MS column with 58% (m/m) aqueous acetonitrile mobile phase containing 5.0 × 10-3 mol kg-1 acetate buffer (pH 3.5), 1.0 × 10-4 mol kg-1 tetrabutylammonium bromide and 1.0 × 10-3 mol kg-1 ethylenediaminetetraacetic acid and detected at 595 nm. The calibration curve was linear up to 35 ng for vanadium(V) in 25.0 mL of test solution at 0.001 absorbance unit full scale. The detection limit was 2 pg for vanadium(V) with 100 L injection. The method showed good accuracy, selectivity and sensitivity for the determination of vanadium(V) in environmental samples.

β-cypermethrin (β-CP) is one of the most frequently and widely used kind of insecticides. Increasing use of β-CP has posed potential adverse effects on the environment; therefore, it is critically necessary to develop remediation strategies to remove β-CP from the environment. In this study, bioremediation efficiency of β-CP contaminated soils was assessed based on the results of laboratory experiment. The selected bacterium Achromobacter sp. strain P-01 was used to degrade β-CP and its major metabolite 3-phenoxybenzoic acid (3-PBA) in different soils. Studies on bioremediation in sterilized soil showed that strain P-01 exhibited efficient degradation of β-CP and 3-PBA (both 50 mg·kg-1) with a rate constant of 0.1857 and 0.1084 day-1, respectively. The degradation process followed the first-order kinetics and the half-life (T1/2) for β-CP and 3-PBA was 3.7 and 6.4 days, respectively. Studies on bioremediation in non-sterilized soil showed that degradation rates were 90.4% and 70.6% for β-CP and 3-PBA within 10 days after strain P-01 introduction, which was characterized by a constant of 0.3334 and 0.1341 day-1, respectively. Comparing with the control without inoculum, T1/2 for β-CP and 3-PBA reduced by 21.6-154.8 days. These results indicated that strain P-01 may have potential for use in bioremediation of β-CP contaminated environment.
β-氯氰菊酯(β-CP)是一种使用最频繁、应用最广泛的杀虫剂。越来越多地使用β-CP对环境造成了潜在的不利影响;因此，迫切需要开发修复策略来去除环境中的β-CP。本研究在室内试验的基础上，对β-CP污染土壤的生物修复效果进行了评价。选用无色杆菌P-01菌株降解不同土壤中β-CP及其主要代谢物3-苯氧苯甲酸(3-PBA)。无菌土壤生物修复研究表明，菌株P-01对β-CP和3-PBA(均为50 mg·kg-1)具有较好的降解效果，降解速率分别为0.1857和0.1084 d -1。降解过程符合一级动力学，β-CP和3-PBA的半衰期(T1/2)分别为3.7和6.4 d。对未灭菌土壤的生物修复研究表明，菌株P-01引入后10 d内，β-CP和3-PBA的降解率分别为90.4%和70.6%，降解常数分别为0.3334和0.1341 d -1。与未接种的对照相比，β-CP和3-PBA的T1/2缩短了21.6 ~ 154.8 d。这些结果表明，菌株P-01可能在β-CP污染环境的生物修复中具有潜在的应用价值。

Carbon isotopes in loess through S0 to S11 at Luochuan section in Shanxi province, China were studied. The curve of δ13C compares well to that of the oxygen isotope in deep sea sediments from Deep Sea Drilling Project Site 607 drill hole. There is a negative peak of δ13C within S5 paleosol where the content of δ13C is -16.6150/00, shows that the climatic of that period is optimum, and the vegetation is likely forest. Compared with the pollen analysis, we conclude that the vegetation type of palesol S0,S1,S4,S8,S9, whose δ13C content is -5.85--10.000/00, is forest-grass. The d13C content of paleosol S2, S3, S6, S7 is -8.72~-6.950/00, and their vegetation is grass. The loess layer L1, L2, L5, L6, L8, L9 represent the severe cold-dry glacial period with the δ13C content of -3.7- -2.270/00, and their vegetation belongs to steppe-desert. The research of paleo-vegetation type is significant to anti-soil erosion in the loess plateau of China.

Adsorption model, dynamic mechanism and adsorption thermodynamic property of the version resin are discussed in this study. The results shows that Freundlich equation can favorably associate with the adsorption of fluoride ion on the D401 version resin. The adsorption process of fluorine for modified is carried out according to Freundlich adsorption model. The adsorption process is control by internal diffusion. The defluoridation material has good capability of defluoridation and the adsorption process is exothermal chemical adsorption. So rising temperature will go against the adsorption.

Bentonite has the advantages of strong hygroscopicity, expansibility, adsorptivity and adhesivity. It can ameliorate and reclaim soils. This research focused on the oil contaminated soils amendment by bentonite. The oil contaminated soils were characterized with different techniques and compared with the background soils to evaluate its contaminating level. The results indicated that the soils were heavily contaminated with oil and its ventilation, porosity and bioaccessibility were greatly affected. The addition of bentonite could affect the physical-chemical properties of soils and the possible mechanisms were discussed. It was demonstrated that bentonite addition could improve the soils water conservation, the air ventilation in soil and the sticky particles percentage. However, the pH increased a little by adding bentonite. The addition of bentonite could enhance the oil degradation.

The 2011 Sendai Earthquake has hit the north-east of Japan triggering a destructive tsunami that has caused extensive damage. A fast and effective post-disaster assessment is highly imperative for the recovery of this region. This study modeled the tsunami-affected areas of coastal Fukushima Prefecture using Landsat-7 ETM+ data and terrain analysis. The result shows that most of the coastal areas were significantly affected by the tsunami. The low-lying plains along the coast are particularly vulnerable to the tsunami.

For creating surrogate model of the groundwater numerical simulation model of Jinquan Industrial Park in Inner Mongolia, the application of Monte Carlo sampling method and Latin Hypercube Sampling method in pumping test design is studied. Firstly make sure the pumping load of each pumping wells obeys uniform distribution, then generate Monte Carlo samples and Latin Hypercube samples according to their own methods. Analyses these two results comparing with each other, it suggests that in small sample size, Monte Carlo sampling method has a low sampling efficiency, low coverage of the sampling value to population and needs a large amount of calculation, while Latin Hypercube Sampling method relatively improves the sampling efficiency, coverage of the sampling value to population, and reduce the workload. Latin Hypercube Sampling method has better practicability in this job.

Due to the climate change, human activities and other factors, there are some inter-annual or inner-annual alterations happened in the hydrological series. Many important works had been affected severely, such as the planning and designation of hydraulic engineering, the sustainable utilization and optimal allocation of water resources etc. However, the studies about the features of inner-annual hydrologic elements distribution are mainly focused on the analysis of the inhomogeneity, with the disadvantage of unintuition and the poor comparability of the indicators from the view of methods that used nowadays, few of the studies considering the alteration of the inhomogeneity happened or not under the changing environment. Therefore, the Gini Coefficient with the advantage of well description of inhomogeneity is used to set up the analysis method of hydrological alteration of the inner-annual distribution. In this method, the series of homogeneity of inner-annual hydrological elements distribution will be calculated first of all, then the Hydrological Alteration Diagnosis System is used to analyze whether the alteration is happened in the series or not, finally, the mean difference method will be employed to analyze the attributions if the alteration is existing. At the end of this study, with the monthly runoff data from the year of 1954 to 2005 of Longchuan Station at Dongjiang River, the alterational characteristics of inner-annual runoff distribution is calculated and the attribution analysis is conducted in succession. The results show that: at the year of 1973, the increasing jump alteration happened in the series of inner-annual runoff distribution, which means the tendency of inner-annual runoff distribution becomes equalization. About 60% of the alteration is induced by the human activities, especially the construction and operation of Fengshuba Reservoir, and the factor of climate change only accounts for about 40%.

About 60% of the alteration is induced by the human activities, especially the construction and operation of Fengshuba Reservoir, and the factor of climate change only accounts for about 40%.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75850860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
