Research ArticleOpen accessIn the abstractChemical Contaminants and Toxicity of Ganga River Sediment from Up and Down Stream Area at KanpurK. R. Beg, S. AliThe objective of this study was the sediment quality assessment of Ganga River at Kanpur city where effluents from tannery industries are discharged. Sediment samples from upstream and downstream area were collected and analyzed for trace metals and toxicity bioassay. Among various trace metals examined Cr in downstream sediment was 30-fold higher than in upstream sediment and its concentration was … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,608 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMass Spectrometry/Mass Spectrometry Study on the Degradation of B-Aflatoxins in Maize with Aqueous Citric AcidA. Méndez-Albores, I. Nicolás-Vázquez, R. Miranda-Ruvalcaba, E. Moreno-MartÍnezDegradation of B-aflatoxins in maize by means of 1N aqueous citric acid was confirmed by the AFLATEST immunoaffinity column method, High Performance Liquid Chromatography (HPLC), tandem mass spectrometry (MS/MS) and computational information. The AFLATEST and HPLC assays showed that 96.7% degradation occurred in maize contaminated with 93 ng g-1 when treated with the aqueous citric acid. Two major products, produced … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 2 · 30 Jun 2008 · 8,054 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Engineer's Mathematical Approach to Designing an Emergency Room Decontamination Area for Weapons of Mass Destruction CasualtiesEldo E. Frezza, Erica Fletcher, Veronica Flores et al.This study will focus on the potential requirements for an emergency response facility in case of weapons of mass destruction casualties proposing mathematical models. A complete emergency room layout will be designed taking the following analyses and requirements into consideration: quality function development (QFD) and product layout; average number of patients in the system, average time in the system, average … …Journal of Social Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 8,433 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Mixing on the Biological Degradation of Toluene under Aerobic ConditionsAbdel E. Ghaly, D.G. Rushton, K. MartinellThe effectiveness of in-vessel bioremediation in reducing the concentration of toluene in contaminated soil under continuous and intermittent mixing conditions using invessel composting system. The results showed that there was a startup period (60 h) during which the average temperature rose from 21 to 32 and 40°C (and then remained constant) for the bioreactors with continuous and intermittent mixing, respectively. … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,503 accessesView PDF Cite
