Research ArticleOpen accessIn the abstractBiological Activity of Methyl tert-butyl Ether in Relation to Soil Microorganisms has a Negative Environmental ImpactGholam H.S. BonjarFuel oxygenates are added to gasoline to enhance combustion efficiency of automobiles and reduce air pollution. Methyl tert-butyl ether (MTBE) is the most commonly used oxygenate because of its low cost, high-octane level and ease of blending with gasoline. However, due to its water solubility, high mobility and low biodegradability it leaches in soil subsurface at the speed of groundwater. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,661 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordComparison of Microbial and Heavy Metal Contents in Soils and Roots under Mangrove Forest Stands with Different Levels of Pollution in the Niger River Delta, NigeriaAroloye Ofo NumbereOil and gas exploration in the Niger Delta, has resulted to increased heavy metal contamination. It is thus postulated that increased heavy metal will lead to decreased microbial content in soil and root. To test this hypothesis ten replicates each of soil and root samples were collected from already established sites. Samples were sent to the laboratory for analyses of … …American Journal of Applied Sciences, Vol. 15, Issue 2 · 25 Jun 2017 · 8,177 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBioremediation of Petroleum Hydrocarbon-Polluted Mangrove Swamps Using Nutrient Formula Produced From Water Hyacint (Eicchornia crassipes)Frank Anayo Orji, Abiye Anthony Ibiene, Phillip O. OkerentugbaLaboratory-scale studies were carried out using a nutrient formula produced from Eicchornia crassipes plant to achieve bioremediation of crude oil impacted mangrove soil. In a 70 day study, the culturable heterotrophic bacterial population of the Eichhornia crassipes recipe increased from 6.26×105 Cfu/g to 2.69×107 Cfu/g. The control set-up had its total culturable bacterial count increased from 5.76×105 Cfu/g to 1.24×106 … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,643 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPetroleum Hydrocarbon Pollution of Mangrove Swamps: The Promises of Remediation by Enhanced Natural AttenuationF. A. Orji, A. A. Ibiene, O. C. UgboguProblem statement: The Remediation by Enhanced Natural Attenuation (RENA) is currently being used as a cleanup technology in polluted environments in the Niger Delta and other parts of the globe. The effectiveness of RENA as a remediation technology in the most recent time has been challenged by few authorities. The deleterious effects of pollutants on the environment have led to … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 12 May 2012 · 8,225 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordTotal SO2 Emissions from Power Stations and Evaluation of their Impact in Kuwait Using a Gaussian Plume Dispersion ModelA.A. Ramadan, M. Al-Sudairawi, S. Alhajraf, A.R. KhanIn Kuwait, most of the power stations use fuel oil as the prime source of energy. The sulphur content (S%) of the fuel used as well as other factors have a direct impact on the ground level concentration of sulphur dioxide (SO2) released by power stations into the atmosphere. The SO2 ground level concentration has to meet the environmental standards … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 6,850 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordReduction of Ammonia Volatilization through Mixing Urea with Humic and Fulvic Acids isolated from Palm Oil Mill Effluent SludgeShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization from surface-applied urea may be substantial but it is possible to control it by mixing urea with acidic substances such as Humic Acids (HA) and Fulvic Acids (FA). The objective of this study was to compare the effects of urea-HA, urea-FA, urea-acidified (HA+FA) mixtures on ammonia loss, soil pH, soil exchangeable ammonium and available nitrate accumulation … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,350 accessesView PDF Cite
