Research ArticleOpen accessIn the abstractBONE MEAL AS ALTERNATIVE TREATMENT FOR ACIDIC AND METAL CONTAMINATED ACID MINE DRAINAGE WATER EFFLUENT: LAB SCALECarolyn Payus, Olga David, Moh Pak YanThe typical methods of treatment for acidic and metal contaminated water effluent such as the Acid Mine Drainage (AMD) will always focus on either civil engineering methods, such as disposal, excavation, drainage and encapsulation or process based technologies such as effluent washing and treatment. These techniques are not environmental friendly, costly and unsustainable, thus environmental damaging. Nowadays, there is a … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 3 Mar 2014 · 7,981 accessesView PDFCite

CholewaUnderstanding the dynamic of metals in soil and plantsis essential for ecosystem management and risks assessment of environmental pollution and sustainability.The main objective of the present study is to determine the mobility of Ni, Cu, Fe, Mg and Zn in soil and their translocation in D. cespitosa plants in a mining region in Northern Ontario.The total amount of Cu, Ni, … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 15 Jan 2014 · 8,682 accessesView PDFCite
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 · 7,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metal Uptake and Translocation by Dipterocarpus verrucosus from Sewage Sludge Contaminated SoilKeeren Sundara Rajoo, Arifin Abdu, Daljit Karam Singh et al.Sewage sludge or biosolids is the solid waste that has been left after wastewater is treated in a domestic wastewater treatment facility. The most common way of sludge disposal is to dispose it on the land, sea or air (incineration). However, these methods are not environment-friendly, costly and time consuming that requires expertise and knowledge. An ideal way to manage … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 10 Jul 2013 · 7,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosorption of Ternary Cadmium, Nickel and Cobalt Ions from Aqueous Solution onto Saccharomyces cerevisiae Cells: Batch and Column StudiesMaedeh Galedar, Habibollah YounesiThe aim of this study was to remove cadmium, nickel and cobalt ions from aqueous solutions using yeast, Saccharomyces cerevisiae, pre-treated with ethanol. The cells are immobilized using polysulfone in both batch and continuous systems. To optimize the adsorption capacity of the yeast biomass, a batch system was used to investigate the effects of initial pH, initial biomass dose and … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 7,954 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegumming of Raw Silk Fabric with Help of Marine Extracellular ProteaseDas Sumana, Mathummal Sudarshan, Ashoke Ranjan Thakur, Shaon RayChaudhuriProtease secreting microbe was isolated and characterized on the basis of their morphological, biochemical, physiological and 16S rDNA based molecular properties. The extracellular protease was quantified and characterized. Protease was used for different time (4, 8, 12 and 24 h) at different temperature (RT and 37°C) for optimization of the degumming process for raw silk fabric with enzyme dosage (0.2-1 … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,504 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbolishing Toxicity of Copper by Some Environmental Factors Using Green Alga Chlorella vulgarisAdel A. Fathi, Mohamed M. Azooz, Mohamed A. Al-FredanA variety of environmental factors are known to modify the toxicity of heavy metals on algae. This study was undertaken to examine the impact of some inorganic and organic complexes on the toxicity of copper using the isolated algal species (Chlorella vulgaris). The data illustrate that the amount of available forms of copper (copper free ions) gradually decreased with increasing … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 2 Jan 2013 · 6,764 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.
