Increase of impervious surfaces in urban area followed with increases in runoff volume and peak flow, leads to increase in urban storm water pollution. The polluted runoff has many adverse impacts on human life and environment. For that reason, the aim of this study was to investigate the efficiency of nano iron oxide coated sand with and without magnetic field in treatment of urban runoff. In ...

production of high quality with high shelf life of apple fruits, is of great importance. present study investigates the effects of ammonium nitrate and iron on quality and antioxidant properties of apple fruit cultivar gala in a randomized complete block design. foliar application of iron chelate in three levels (0, 5 and 10 mg/l) and soil nutrition of ammonium nitrate in three levels as strip ...

Gleptoferron, a sterile aqueous colloidal solution of beta-ferric oxyhydroxide and dextran glucoheptonic acid, was compared with iron dextran for the prevention of Fe deficiency anemia in young pigs. Using 26 litters, pigs (within each litter) were randomly allotted to one of three treatments: 1) control (no Fe), 2) iron dextran (200 mg) and 3) gleptoferron (200 mg). Blood was collected at 0, 1...

iron (in zero-valent and oxide forms) is used to remove numerous organic and inorganic contaminants in environment. however, there are few reports, especially in nano scale, on the remediation of heavy metals contaminated soils using zero-valent iron in the literature. in this study, the effect of iron on the availability of heavy metals was evaluated in a calcareous soil spiked with cadmium, z...

Desferrioxamine, widely used for the treatment of iron overload in Cooley's anaemia, binds iron so tightly that it should quantitatively remove iron from transferrin. Studies conducted in vivo and in vitro, however, have failed to demonstrate significant depletion of transferrin-bound iron by a stoichiometric excess of desferrioxamine. However, low molecular weight chelating agents, capable of ...

Oxidation of cyclooctene was studied in presence aqueous hydrogen peroxide (30%, v/v) over nano iron oxide. The catalyst prepared by microemulsion method and characterized using various techniques including XRD, TEM and BET techniques for evaluating phase, structure and morphology and surface area. In this study, we investigated the effects of varying the catalyst content, reaction temperature,...

Iron promotes DNA damage by catalyzing hydroxyl radical formation. We examined the effect of chromatin structure on DNA susceptibility to oxidant damage. Oxygen radicals generated by H2O2, ascorbate and iron-ADP (1:2 ratio of Fe2+:ADP) extensively and randomly fragmented protein-free DNA, with double-strand breaks demonstrable even at 1 microM iron. In contrast, polynucleosomes from chicken ery...
