Research ArticleOpen accessIn the abstractAssessment of the Water Quality Index of Otamiri and Oramiriukwa RiversA.N. Amadi, P.I. Olasehinde, E.A. Okosun, J. YisaProblem statement: The impact of anthropogenic activities on Otamiri and Oramiriukwa Rivers as a result of the increasing rate of urbanization in Owerri, Nigeria is of a great concern due to the fact that water from these rivers is the source of water distributed for public use. These rivers are of particular importance in the study of surface water pollution … …Physics International, Vol. 1, Issue 2 · 31 Dec 2010 · 8,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrocarbon Biodegrading Potentials of a Proteus vulgaris Strain Isolated from Fish SamplesPatience O. Olajide, L. B. OgbeifunA Proteus vulgaris bacterium SR-1 was isolated from a freshly killed fish sample collected close to the point of crude oil spill in the Niger Delta region, Nigeria. Problem statement: The application of native bacterial species in bioremediation processes has long been desired, because they would be cost effective and efficient in terms of acclimation time. The ability to isolate … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 8,277 accessesView PDFCite

Research ArticleOpen accessIn the abstractAnalytical Studies on Water Quality Index of River LandzuJ. Yisa, T. JimohProblem statement: River Landzu is of particular importance in the study of surface water pollution because effluents from cottage industries, municipal sewage, agricultural and urban run-off are discharged into it bringing about considerable change in the water quality. Approach: This study aimed at using the application of Water Quality Index (WQI) in evaluating the quality of River Landzu for public … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 11,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Optimization of Fermentation Conditions for Cellulase Production from Palm Oil Mill EffluentJamal I. Daoud, Md. Zahangir AlamProblem statement: Palm oil mill effluent discharged by the oil palm industries is considered as the mixed of high polluted effluent which is abundant (about 20 million tonnes year-1) and its effect contributes to the serious environmental problems through the pollution of water bodies. Approach: The aim of this study was to identify the potential of low cost substrate such … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 8,192 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccumulation of Heavy Metals in Tilapia Fish (Oreochromis niloticus) from Al-Khadoud Spring, Al-Hassa, Saudi ArabiaMohammed A. Al-KahtaniProblem statement: Al-Khadoud Spring is one of the largest spring in Al-Hassa governorate (Saudi Arabia). Due to the extended domestic activities and urbanization as well as the continuous industrial and agricultural growth of the region, spring water quality is potentially changing. Approach: This study was conducted to measure toxic heavy metal concentrations in water and fish samples along the spring … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 11,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review: Potentiality of Zooplankton as BioindicatorZannatul Ferdous, A. K.M MuktadirProblem statement: This review tended to summarize some recent research on zooplankton as bioindicator in India and some other countries of the world.
