Research ArticleOpen accessAll words, across the recordPublic Perception of Local Communities towards the Sustainable Management of Laguna Lake, PhilippinesGlenn L. Sia Su, Julio CervantesCommon failures in resolving multiple use conflicts are attributed to the inability of institutions to recognize and incorporate people's perceptions towards the resource. This study aims to determine the local communities' perceptions and factors influencing their perceptions towards Laguna Lake and its sustainable management. Copies of a self-administered questionnaire were distributed to systematically selected householders situated near and far from … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,256 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordTreatment of Wastewater by Natural Lagoon for its Reuse in IrrigationM. Driche, D. Abdessemed, G. NezzalThe process of natural lagoon consists in purifying the waste water by simple flow of the effluent in not very deep ponds where proliferate bacteria, algae and other living organisms, under a surrounding air and in the presence of a solar radiation. For this study, which is spread out over 3 years (2004-2006) and which still continues, we chose the … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,181 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSulfur Dioxide (SO2) Accumulation in Soil and Plant's Leaves around an Oil Refinery: A Case Study from Saudi ArabiaM. O. Al-Jahdali, A. S. Bin BisherThe accumulative levels of SO2 in soil and plant's leaves around an oil refinery were monitored. Four different sites around the refinery area were chosen; west, south east, north east and the northern side. The refinery southern side was not accessible. In addition to the soil samples, leaves samples of the dominant plants species Myoporum pictum were randomly collected from … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,790 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 recordThe Effects of North America Free Trade Agreement on Mexican Environmental Policy (1994-2004)Ningu J. Kenneth, Jorge Torres Jácome, Sonia E.S. Gomez, Pérez ÁvilesThe scope of this study was to analyze the implementation of the environmental policy and the way Mexico has integrated the environmental aspects into a North America Free Trade Agreement (NAFTA). We are aware of the fact that many environmental costs do not necessarily reflect the environmental damage. Environmental costs are often defined by determining either the willingness of the … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 6,357 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMathematical Modelling of Pollutants’ Dispersion in Soil I. Case Study of Copper DispersionV. Viman, L. M. Cozmuta, A. M. Cozmuta et al.The study presents a mathematical modelling of copper dispersion in soil. The samples have been collected from the same points of the sampling network, from surface and depth in 2001 and only to surface in 2002 and analyzed using the ICP-AES method. The extrapolation of the experimental results led to the dispersion curves of the copper concentrations both at surface … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,477 accessesView PDF Cite
