Research ArticleOpen accessPhrase in the titleModeling the Evolution of Nitrate Pollution of Groundwater in the Plain of Western Middle CheliffNessrine Belmiloud, Naïma BettaharGroundwater constitute a potential source of drinking water supply and should, consequently, benefit from the necessary protection against the various forms of pollutions, particularly those diffuse of agricultural origin. The plain of Western Middle Cheliff which contains an important resource in groundwater supplying the whole population of the province of Chlef and contributing to the satisfaction of the need for … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 12 Jan 2016 · 7,141 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGroundwater Dynamics and Quality Assessment in an Agricultural AreaStefano Lo Russo, Adriano Fiorucci, Bartolomeo VignaProblem statement: The analysis of the relationships among the different hydrogeological Units and the assessment of groundwater quality are fundamental to adopt suitable territorial planning measures aimed to reduce the potential groundwater pollution especially in agricultural regions. In this study, the characteristics of groundwater dynamics and the assessment of its quality in the Cuneo Plain (NW Italy) were examined. Approach: … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 29 Sep 2011 · 7,367 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPotential Air and Groundwater Pollution from Continuous High Land Application of Cheese WheyA.E. Ghaly, D.G. Rushton, N.S. MahmoudExperiments were performed, using eighteen 280 cm deep soil columns with 20 cm inside diameter, to determine the relative amounts of nitrogenous compounds leached and volatilized from soils receiving high application rates of cheese whey during two seasons. Three soils (loamy sand, sandy loam and sandy clay loam) and two cheese whey application rates (560 and 840 kg-N ha-1), that … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,277 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation of Nitrate and Phosphate Removing Bacteria from Various Environmental SitesS. DebRoy, S. Das, S. Ghosh et al.Problem statement: Nitrate and phosphate are two major pollutants due to anthropogenic activity like excessive use of fertilizers in agriculture. Their contamination has emerged as a global problem and its potential threat is marked on the environmental sustainance as well as on the public health. Approach: The objective of the current study is to isolate efficient nitrate and phosphate removing … …OnLine Journal of Biological Sciences, Vol. 12, Issue 2 · 29 Jun 2012 · 9,348 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Abattoir and Saw-Mill Effluents on Water Quality of Upper Ogun River (Abeokuta)A. O. Adeogun, A. V. Chukwuka, O. R. IborProblem statement: The unregulated discharge of contaminants from point sources into inland freshwater aquatic systems and the resultant deterioration of water quality are largely undocumented in developing countries like Nigeria especially with respect to the role of seasonal factors on the recovery capacity of aquatic systems. Approach: The aim of this study was to assess the impact of abattoir and … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 6 Jan 2012 · 8,634 accessesView PDFCite
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 abstractAssessment of Pollution Hazards of Shallow Well Water in Abeokuta and Environs, Southwest, NigeriaE. O. Orebiyi, J. A. Awomeso, O. A. Idowu et al.Problem statement: Pollution of well water, either from point or non-point sources, has become a thing of health concern both in urban and rural areas. Approach: This study aim at assessing the pollution hazards of groundwater resource by sampling some shallow wells from urban and peri-urban area of Abeokuta.

Research ArticleOpen accessIn the abstractControlling Ammonia Volatilization by Mixing Urea with Humic Acid, Fulvic Acid, Triple Superphosphate and Muriate of PotashShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Inefficient use of inorganic fertilizer such as urea is caused by substantial losses of ammonia when urea is surface-applied. Ammonia losses can be controlled by adding acidic material such as TSP, HA or FA. In order to reduce ammonia loss and retain soil exchangeable ammonium and available nitrate as well as producing complete organic based fertilizer, this study … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 9,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mixing Urea with Humic Acid and Acid Sulphate Soil on Ammonia Loss, Exchangeable Ammonium and Available NitrateMohd Taufik Mohd Yusuff, Osumanu Haruna Ahmed, Nik Muhamad Ab MajidProblem statement: Ammonia loss due to rapid hydrolysis of urea in soil following surface application can be substantial. Ammonia loss in agriculture is estimated to be 1 to 60%. This laboratory study compared the effect of three different urea-humic acid-acid sulphate soil mixtures on NH3 loss and soil ammonium and nitrate contents, with loss from surface applied urea without additives … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 8,906 accessesView PDFCite
