Research ArticleOpen accessIn the abstractRecovery of Lead(II) from Aqueous Solutions by Zea mays Tassel BiosorptionCaliphs M. Zvinowanda, Jonathan O. Okonkwo, Nana M. Agyei et al.Problem statement: Major adsorbent materials used in heavy metal ion removal from polluted aqueous streams are expensive and difficult to regenerate. In this study, the possibility of using Zea mays tassel, as an alternative low cost biosorbent material to remediate heavy metal pollution was investigated. Lead (II) was used because of its wide application in industrial products and well documented … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 8,465 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuitability Evaluation of Groundwater for Irrigation, Drinking and Industrial PurposesM. A. Hakim, A. S. Juraimi, M. Begum et al.Problem statement: Groundwater is an important source of freshwater for agricultural, drinking and domestic uses in many regions of the world including Bangladesh. Demand of groundwater has been increasing day by day for irrigation by bringing more area under cultivation. As a drinking water the bottled water market currently has an average annual growth rate of 7.4% between 2002 and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 8,644 accessesView PDFCite
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 · 7,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Soil Solution Chemicals after Tannery Effluents DisposalCélia A. Surita, Thomas Gloaguen, Célia R. Montes, Carlos T.S. DiasKnowledge about soil solution chemicals is important for assessing their mobility, availability, migration to groundwater and toxicity to plants. The objective of this study was to apply factor analysis to data obtained on soil solution chemicals during a one-year monitoring program in a controlled experiment with tannery effluents disposed on the soil surface, to extract information on their relationship and … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,772 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordWater Characteristics Assessment, Bioaccumulation and Health Risk Evaluation of Possible Ingestion of Toxic and Essential Metals in Chromidotilapia guntheri Sourced from Ada River, West AfricaTunde Ohiokhioya Thaddeus Imoobe, Eugene Iragboghie Okhakhu, Osikemekha Anthony AnaniThe water ecosystem has been acclaimed to be polluted with various chemicals that may pose possible risks to the biota therein and affect the end consumers who ingest them via the food chain system. This study evaluates the water characteristics, bioaccumulation and non-carcinogenic risk potentials in the ingestion of toxic metals like (Cu, Fe, Zn, Mn and Pb) in Chromidotilapia … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 18 Mar 2024 · 4,772 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExpression of Metallothionein-Like Protein 2B Gene Induced by Different Concentrations of Copper in White Spruce (Picea glauca)Megan McKergow, Kabwe NkongoloThe alterations to the expressions of metal transporter genes can induce metal ion uptake to maintain cell homeostasis when metal concentrations are low. Metallothioneins (MTs) are a class of low molecular mass (4-8 kDa), cysteine (Cys)-rich proteins that can bind metals via the thiol groups of their Cys residues. Studies on MT gene expressions in higher plants, such as conifers, … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 25 Dec 2022 · 5,118 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect 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
