Research ArticleOpen accessIn the abstractInfluence of Oil Contamination on Geotechnical Properties of Basaltic Residual SoilZulfahmi Ali Rahman, Umar Hamzah, Mohd. Raihan Taha et al.Problem statement: Oil contamination due to accidental spillage or leakage brings hefty damage to the environments. It percolates steadily into subsurface environments and contaminates the soil and water system. Hydrocarbon contamination has not just affected the quality of the soil but will also alter the physical properties of oil-contaminated soil. Approach: This study presented the geotechnical properties of oil-contaminated soils … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 10,271 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Potassium and Calcium Hydroxide, Compost and Humic Acid from Sago (Metroxylon sagu) WasteC. P. Auldry, O. H. Ahmed, A.M. Nik Muhamad et al.Problem statement: Agriculture waste such as Sago Waste (SW) has a potential to cause pollution when the waste is discarded into rivers. In order to add value to SW, a study was conducted to produce potassium and calcium hydroxide, compost and Humic Acid (HA) from SW. Approach: The SW was air-dried and some grinded. The grinded SW was incinerated at … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of Metals (Pb and Cu) Contamination in Bottom Sediment from South China Sea Coastal Waters, MalaysiaM. C. Ong, B. Y. KamaruzzamanProblem statement: The accumulation of metal contaminants in sediments can pose serious environmental problems to the surrounding areas. Trace metal contamination in sediment could affect the water quality and the bio-assimilation and bioaccumulation of metals in aquatic organisms, resulting in potential long-term implications on human health and ecosystem. Approach: About 154 bottom sediment samples were collected using Smith McIntyre in … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,995 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 · 9,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Management of Effluents from Small Piggery Farms in MexicoJ.L. de Victorica-Almeida, M. Galván-García, R. Ayala-RuizIn Mexico, pig farming is the third most important livestock activity due to its contribution to the total meat production. However, it is estimated that around 38% of pig farms dispose their wastewaters without any treatment directly into the nation’s water bodies, which in turn has a severe impact in the environment. One reason for not treating is the high … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,369 accessesView PDFCite
Research ArticleOpen accessIn the abstractOlive Wastewaters' Impact on Oued Boufekrane in Meknes-TafilaletMajdouline Larif, Abdelmajid Soulaymani, Mohammed Hnach, Azzedine ElmidaouiProblem statement: Water quality of river Boufekrane is subject to heavy pollution exerted by population growth and industrial activity, including the OMW from the olive industry in which the presence of polyphenols and toxic effect dominant character may generate a higher organic pollution. Approach: Our objective is to "study the impact of OMW by analyzing the physicochemical parameters on seven … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 20 Apr 2012 · 7,519 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Lead in Soil along the Highways of KosovaAlbert Maxhuni, Fatmir Faiku, Musaj Pacarizi et al.Problem statement: During recent several decades soil was polluted more and more serious by heavy metals because of mining, smelting, irrigating with sewerage and some other human activities. These heavy metals may adversely affect soil ecology, agricultural production or product quality and ground water quality and will ultimately harm to health of mankind by food chain. Approach: We had analyzed … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 6 Jan 2012 · 7,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractFish Spoilage Mechanisms and Preservation Techniques: ReviewA. E. Ghaly, D. Dave, S. Budge, M. S. BrooksProblem statement: Spoilage of food products is due to chemical, enzymatic or microbial activities One-fourth of the world’s food supply and 30% of landed fish are lost through microbial activity alone. With the ever growing world population and the need to store and transport the food from one place to another where it is needed, food preservation becomes necessary in … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 59,853 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemical Characteristics of Compost and Humic Acid from Sago Waste (Metroxylon sagu)Auldry Chaddy Petrus, Osumanu Haruna Ahmed, Ab Majid Nik Muhamad et al.Problem statement: Agriculture waste such as Sago Waste (SW) has a potential to cause pollution either on land or in water. In order to reduce this problem, a study was conducted to investigate the effect of three different treatments on the chemical characteristics of compost and humic acid from SW. Approach: The study had three treatments which were: T1: SW … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 8,092 accessesView PDFCite
