Research ArticleOpen accessIn the abstractIn-Vivo Evaluation of Hexavalent Chromium Induced DNA Damage by Alkaline Comet Assay and Oxidative Stress in Catla catlaKantha Deivi Arunachalam, Sathesh Kumar Annamalai, Jaya Krishna KuruvaIn the present study, the acute toxicity of Chromium in fingerlings of Catla catla, an Indian major carp, was evaluated with renewal bioassay method. In vivo studies were designed to assess the extent of Micronucleus Assay, Comet Assay under the exposure of common heavy-metal compounds, namely, Chromium Nitrate, using Catla catla (2n = 20), as a test model. The laboratory … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 15 Jan 2014 · 7,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Chromium(VI) on Serum Iron and Removal of its Toxicity by Combining Deferasirox and Deferiprone Chelators in RatsS. Jamil A. Fatemi, Marzieh Iranmanesh, Faezeh Dahooee BaloochThe present research is aimed to characterize the potential efficiency of two chelators after chromium(VI) administration for 60 days following two doses of 15 and 30 mg kg-1 chromium(VI) per body weight daily to male rats. However, the hypothesis that the two chelators might be more efficient as combined therapy than as single therapy in removing chromium(VI) from bood serum … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 4 · 30 Oct 2013 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibiotic Resistance and Chromium Reduction Pattern Among ActinomycetesPreeti Jain, Alina Amatullah, Samiul Alam Rajib, Hasan Mahmud RezaActinomycetes, one of the most important groups of microbes, exhibit many interesting activities such as degradation and transformation of organic and metal substrates together with production of antibiotics. With these bioactivities, actinomycetes would play an important role in the webs of the marine environment. The present study was designed to evaluate the antibiotic resistance pattern, antibiotic producing potential and chromium … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 8,905 accessesView PDFCite
Research ArticleOpen accessIn the abstractHexavalent Chromium Removal by Litchi chinensis Sonn PeelIsmael Acosta-Rodriguez, Rigoberto Martinez-Perez, Juan F. Cardenas-Gonzalez et al.Problem statement: We studied the Chromium (VI) removal capacity in aqueous solution by the litchi peel. Approach: We use the diphenylcarbazide method to evaluate the metal concentration. Results: The highest biosorption of the metal (50 mg L-1) occurs within 6 min, at pH of 1 and 28°C. According to temperature, the highest removal was observed at 40 and 50°C, in … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 1 · 1 Mar 2012 · 8,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Orthosiphon stamineus B. for Phytoremediation of Heavy Metals in Soils Amended with Sewage SludgeArifin Abdu, Najihah Aderis, Hazandy Abdul-Hamid et al.Problem statement: Phytoremediation is a biological treatment where plants are used to remove pollutants from the environment to make them harmless. A study was conducted in a greenhouse at the Faculty of Forestry, Universiti Putra Malaysia on the potential of Orthosiphon stamineus B. planted in sewage sludge for heavy metals uptake. The objective of this study was to evaluate the … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 8,769 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeochemical Distribution of Trace Metals and Assessment of Anthropogenic Pollution in Sediments of Old Nakagawa River, Tokyo, JapanH.M. Zakir, Naotatsu Shikazono, Kazuo OtomoThe geochemical distributions of cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb) and zinc (Zn) were examined in sediments collected from Old Nakagawa River (NR), Tokyo, Japan. A widely used 5-step sequential extraction procedure was employed for the fractionation of the metals and the concentrations were measured in the liquid extracts by inductively coupled plasma mass spectrometry (ICP-MS). The association … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Effect of a Dumpsite to Groundwater Quality in Payatas, PhilippinesGlenn L. Sia SuThe study assessed and compared the groundwater quality of 14 selected wells continuously used in the with (Payatas) and without dumpsite (Holy Spirit) areas at the Payatas estate, Philippines. Water quality monitoring and analyses of the bio-physico-chemical variables (pH, Total Suspended Solids (TSS), Total Dissolved Solids (TDS), total coliform, conductivity, salinity, nitrate-nitrogen, sulfate, color, total chromium, total lead and total … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 9,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosorption of Cr(III) by Microalgae and Macroalgae: Equilibrium of the ProcessIzabela Michalak, Agnieszka Zielinska, Katarzyna Chojnacka, Jan MatulaEquilibrium experiments of chromium(III) biosorption by microalga (Spirulina sp.) and macroalga (Pithophora varia) were investigated in this paper. Influence of the following process parameters was studied: pH, biomass concentration and temperature. The equilibrium of the process was described with Langmuir equation. The model parameters were determined at various process conditions. The best operation conditions for the process were selected: pH … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Chromium Sorption on Biomass Fungi from Aqueous SolutionLouhab Krim, Sahmoune Nacer, Goma BilangoThe kinetics of chromium ions sorption from aqueous solution on fungi biomass have been investigated in a batch system. The experimental data were analysed based on an intraparticle diffusion equation and a pseudo-second-order mechanism, in order to predict the constant rate of sorption and the equilibrium capacity with the effect of initial chromium ions concentration, temperature and initial solution pH. … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 7,418 accessesView PDFCite
