A new Ni(II) Complex with N, N, N', N'-tetrakis( benzimidazol-2-yl-methyl )-1, 2-ethanediamine (EDTB) was synthesized and was characterized by using X-ray diffraction method. The crystallographic parameters are as follow: C38H46N10O11SCl2Ni, Mr=980.52, triclinic, a=10.568(4)Å, b=12.078(5) Å, c = 18.868(7) Å, α = 73.700(7)°, β= 77.081(7)°, γ= 84.500(7)°, V=2251.6(15) Å3, Dc=1.446 Mg/m3, Z=2, F(000)=1020, μ=0.664 mm-1, space group is P1̅ .The distortion have taken place between the structure of free ligand EDTB and that in the nickel complex, which caused the complex to be unstable in crystal form. But the holding of aromatic ring packing and hydrogen bonds in the crystal kept the stability of crystal. Based on the crystal data, the quantum chemistry calculation was performed. Both the crystal structure and the computational results show that the nickel complex presents certain biological activity of eliminating superoxide anion radical (O2-·), and this conclusion is proved by the activity data pl50=4.26 of the complex C38H46N10O11SCl2Ni, so it can be called the model complex of nickel-containing superoxide dismutase(MSOD) and has a certain antioxygenic property. On the other hand, nickel is a harmful metal which occurs widely in the wastewater and contaminated soils, and can be transferred through the food chains. The addition of EDTB and the formation of the above complex just can play a role of chemical immobilization of nickel in environmental medium such as water and soils.

The adsorption capability of peat after pretreatment and the degrading characteristics of immobilized BTEX degrading bacteria on the removal of BTEX were evaluated. Results show that: the adsorption of BTEX by peat could reach balance in 20min. The pseudo second-order equation fitted perfectly the adsorption kinetics curve of peat towards BTEX. The adsorption data obtained were well described by the Freundlich adsorption model. The results indicate that the maximum adsorption capacity was (mg·g-1): (benzene) 0.836, (toluene) 0.890, (ethylbenzene) 1.590, (xylene) 1.814. Peat was also used to immobilize the BTEX-degrading bacteria via adsorption method. The adsorption rate of BTEX on peat could reach 76% after 2 days. The removal rate of BTEX by immobilized bacteria was higher than suspended bacteria, which could reach about 90% over a wide range of concentrations (20-80mg·g-1).

Several studies estimating the function of salsolinol (1 methyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline), a dopamine-derived endogenously synthesized compound, have revealed its involvement in the pathogenesis of neurodegenerative diseases such as Parkinson's disease (PD). Moreover, a number of investigations propose that N-methylated derivates of salsolinol, N-methyl-salsolinol and its metabolite products are also involved in etiopathogenesis of PD. The human brain has a higher concentration of (R) enantiomer of salsolinol than (S)enantiomer, suggesting its enzymatic biosynthesis. Recent studies in our lab have shown salsolinol synthesized from dopamine and acetaldehyde by a novel enzyme called salsolinol synthase. In current investigations, the brains of male Sprague Dawley rats were used for crude extract isolation and HPLC-electrochemical detection (ECD) was used for the activity assay of this putative enzyme. Our results show the enzyme activity of salsolinol synthase to be maximum at 80°C and at pH of 7. The results also showed that amount of Salsolinol synthesized by salsolinol synthase is directly proportional to the amount of substrates dopamine (DA) and acetaldehyde (Ach) at 37°C. Its isoelectric point was 8.0 determined with Off-gel. Further characterization of this putative enzyme is under process which will highlight more profound knowledge about this putative enzyme and hence, will help elucidate the pathogenesis of Parkinson's like diseases and will provide a strong basis for treatment of such neurodegenerative diseases.

Abstract-The catalyst of Fe2O3/Al2O3 was prepared by homogeneous precipitation method using AlCl3·6H2O, FeO3-6H2O and CO(NH2)2 as material, characterized by X-ray diffraction (XRD). In the presence of Fe2O3/Al2O3, the microwave induced oxidation process (MIOP) was conducted for the treatment of synthetic methyl orange wastewater. The factors influencing color removal of methyl orange were investigated and the results showed that: under a given condition (catalyst dosage 2g/L, microwave power 900W, irradiation time 5 min, without adjusted to pH), the color removal efficiency of methyl orange (containing 20mg/L) approached 93.2%. The kinetics results show that the process of treatment accords to first order reaction .It provides an effective technology for the color removal of dye wastewater.

Arsanilic acid is a normal used feed additive in animal breeding. Almost no studies have concerned its effect on the enzymatic activities in earthworms. In present study, we investigated the activities of three important enzymes in cytochrome P450 system: benzoxy- resorufin-O -dealkylase (BROD), Pentoxyresorufin -O- dealkylase (PROD), Methoxyresorufin-O -deethylase (MROD) in earthworm Eisenia andrei exposed to arsanilic acid. 5 different concentration groups of arsanilic acid were designed to simulate the process that arsanilic acid was discharged into soil with animal manure. BROD, PROD, MROD activities in worms were respectively measured in different time after exposure. The results showed that all the three enzymes in worms were inhibited by arsanilic acid. The inhibition extents were BROD>;PROD>; MROD. It also showed time or dose dependent is some treatments. As a conclusion, the three enzymes might be used as biomarker of arsanilic acid contamination in soils.

The surface water quality for the Liu River within the boundaries of Zhangwu was evaluated using single factor pollution index, single factor water quality identification index and comprehensive water quality identification index. Permanganate index (CODMn), ammonium nitrogen(NH4-N), dissolved oxygen (DO), 5-days biochemical oxygen demand (BOD5), petroleum and chemical oxygen demand(COD) from 2001 to 2009 were selected for analysis. All the parameters showed temporal variations. CODMn of 2007 and COD of 2004 during low water period, BOD5 of 2006 during level period, CODMn of 2006 and BOD5 of 2005 and 2006 during high flow period were inferior to the standard for surface water (GB3838-2002, Grade IV).The comprehensive water quality were up to the standard (GB3838-2002, Grade IV). Oxygen-demanding organic matters were the main sources of the contamination, which came from agricultural non-point pollution and domestic sewage, garbage pollution and poultry and animal aqua-culture pollution. In order to improve the quality of river water environment, intensified efforts are required to prevent and control water pollution.
