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
Research ArticleOpen accessIn the abstractReducing the Environmental Impact of Olive Mill WastewaterAwni Khatib, Fathi Aqra, Nader Yaghi et al.Problem Statement: A research was needed to monitor the environmental impact of olive mill wastewater (OMW): production and relative production of olive mill waste. This was achieved by collecting data from 92 local olive mills in order to study the olive production yield, water consumption in olive washing and in oil recovery, wastewater generation relative to olive processed and oil … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Typical Case Study: Solid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanThe current environmental concerns have forced developed and developing countries to reduce air, water and land pollution for sustainable growth. Solid refinery waste is cocktail of hydrocarbons, water, heavy metal and fine solids and is substantial in quantity. The principal processes of waste management focus mainly on waste source reduction, reusing, recycling, composting, incineration with or without energy recovery, fuel … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 9,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Factors Affecting Environmental Behavior of Urban Residents: A Case Study in Tehran City- IranKhalil Kalantari, Hossein Shabanali Fami, Ali Asadi, H. Movahed MohammadiEnvironmental problems such as air and water pollution, urban garbage and climate changes in urban areas are the results of human behavior. Only change in human behavior can reduce these environmental problems. Thus studying attitude and behavior of people is a precondition to change this situation. So the main objective of this study was to find out individual and social … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating Soil Contamination with Kriging Interpolation MethodFatima Zohra Benmostefa LarguecheThe main objective of this study was to investigate whether Kriging is a useful tool to estimate the spatial distribution of ground pollutants in contaminated land. The second objective of this work was a more practical one. It consists on the identification of areas that should be subjected to remedial actions and also on deciding which contaminant needs to be … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 8,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociation of Landscape Metrics to Surface Water Biology in the Savannah River BasinMaliha S. Nash, Deborah J. Chaloud, Susan E. FransonSurface water quality for the Savannah River basin was assessed using water biology and landscape metrics. Two multivariate analyses, partial least square and canonical correlation, were used to describe how the structural variation in landscape metrics may affect surface water biology and to define the key landscape variable(s) that contribute the most to variation in surface water quality. The results … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractClimate Change and its Implications to National SecurityMamunur Rashid, Joy Jacqueline Pereir, Rawshan Ara Begum et al.Problem statement: Climate change is increasingly one of the most serious national security threats which will have significant impacts on natural and coastal resources, ecosystem, human health and settlements, thereby affecting human wellbeing. At the same time, it is likely to influence of large scale human migration, economic and social depression over scarce natural resources and political systems necessary involve … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 8,071 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIntegrated Modeling Framework for Highway Traffic Pollution Estimation and DispersionShu Yang, Yao-Jan Wu, John WoolschlagerAir quality is of great concern to the public. Airborne pollutants, such as carbon monoxide (CO), carbon dioxide (CO2) and Particulate Matter (PM), negatively impact people’s living conditions. In particular, vehicular exhaust is a major source of these pollutants. Extensive previous research has contributed to modeling traffic pollutant emission. Popular approaches include computational simulation-based methods, which have been dominant in … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 13 May 2016 · 7,434 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparison of Air Quality in Kuwait Urban and Industrial AreasHamad B Matar, Talal Almutairi, Nayef Z. Al-MutairiThis paper describes the research carried out to investigate air quality in Kuwait. It examined the results of several years of pollutants data provided by Kuwait Environment Public Authority. The data were obtained from a number of fix monitoring stations. The results of the time series analysis have shown that monitored exposures vary substantially and are unique to the location … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 8 Apr 2020 · 7,976 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBaseline Concentrations of 11 Elements as a Function of Land uses in Surface Soils of the Katangese Copperbelt Area (D.R. Congo)Martin T. Mpinda, Tresor N. Kisimba, Theodore M. Mwamba et al.The Katangese Copperbelt Area (KCA) located south-eastern of D.R. Congo presents high concentration of Metal Trace Elements (MTE) due to a rich natural geochemical background and intense mining activities. However, the lack of data on specific baseline concentrations makes it difficult to assess and monitor the environmental quality of soils in the region. In this study, 11 MTE were measured … …American Journal of Environmental Sciences, Vol. 17, Issue 6 · 3 Jan 2022 · 7,126 accessesView PDFCite
