Review ArticleOpen accessIn the abstractAnalysis of Benzo[a]Pyrene Contamination from an Long-Term Contaminated SoilSvetlana Sushkova, Tatiana Minkina, Abdulmalik Batukaev et al.Analysis of benzo[a]pyrene contamination from an aged contaminated chernozemic, meadow-chernozemic and alluvial soils under the effect of aerotechnogenic emissions from the Novocherkassk regional power plant have been revealed on the basis of annual monitoring studies from 2008 to 2012. A new ecologically clean highly-effective express-method of subcritical water extraction has been developed for determination of benzo[a]pyrene from soils of the … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 16 Nov 2015 · 7,873 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Nickel and Zinc by Residual SoilsNur ’Aishah Zarime, W. Y. Wan Zuhairi, Sivarama KrishnaSoil has long been utilized as low cost liner material to prevent contamination from leachate to groundwater media. To find a suitable soil material for this purpose is a great challenge. This study describes the potential use of residual soil to functions as engineered clay liner for waste disposal landfill in Malaysia. Three types of residual soils were investigated namely … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 5 Dec 2014 · 7,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparing the Fertility of Soils under Khaya ivorensis Plantation and Regenerated Degraded Secondary ForestsYetti Heryati, Arifin Abdu, Mohd Noor Mahat et al.Problem statement: It is widely accepted that conversion of natural forest to other land use types leads to deterioration of soil fertility and increased soil compaction which consequently become degraded secondary forests. Degraded secondary forest or forestland is indicated by low in soil fertility and organic matter due to imbalance input and output from original vegetation. Forest plantation through planting … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Buddha Images and Conservation and Adherence to Cultural Values in NortheastAthikan Suksri, Souneth Phothisane, Sastra Laoakka et al.Problem statement: This study is caused by the problem of conservation of the Buddha images to exist in the original condition and by the problem of transference and adherence to indigenous knowledge of local craftsmen. At present there have not yet been systematic and wide conservation and adherence to the Buddha images. Other causes are such as incorrect techniques of … …Journal of Social Sciences, Vol. 6, Issue 3 · 30 Sep 2010 · 7,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelected Soil Morphological, Mineralogical and Sesquioxide Properties of Rehabilitated and Secondary ForestsB. T. Saga, O. H. Ahmed, A. S. Jamaluddin et al.Problem statement: The tropical rain forests in Southeast Asia have been characterized by several researchers. However empirical data on soil characteristics under degraded forest land in tropical rain forest and rehabilitated program are limited. A study was conducted to evaluate the soil morphology, mineralogical and sesquioxide properties of a rehabilitated degraded forest land (19 years after it was planted with … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,022 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Vegetative Induced Deformation in an Unsaturated SoilNazri Bn Ali, Mu’azu Mohammed AbdullahiProblem statement: Tree root water-uptake increases soil strength by increasing the soil matric suction due to pore pressure dissipation in a soil mass, inducing increases in vertical total stress or water extraction, the effective stress to which the soil strata is subjected to may also increase. This causes volume change which might be detrimental to geotechnical structures and shallow foundation. … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,139 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment on the Effect of Formulative Materials on the Viability and Efficacy of Serratia marcescens-a Biocontrol Agent Against Fusarium oxysporum F. sp. cubense race 4A. S. Y. Ting, M. T. Fang, C. S. TeeProblem statement: Application of biocontrol agents to the field in pre-existing free-cell forms often results in poor cell viability which subsequently affects their efficacy in suppressing pathogen development. There is therefore a need to bioformulate these biocontrol agents not just to enhance their field potential, but for easy storage, delivery and application as well. Approach: In this study, the bioformulations … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Organoclay from Sodium Montmorillonite and Fatty Hydroxamic AcidsWisam H. Hoidy, Mansor B. Ahmad, Emad A. Jaffar Al Mulla, Nor Azowa Bt IbrahimProblem statement: Sodium Montmorillonite (Na-MMT) has been modified via cation exchange reaction using Fatty Hydroxamic Acids (FHAs) synthesized from palm oil as a surfactant to produce organoclay which is used to prepare polymer nanocomposites. Approach: Basal spacing, functional groups identification and thermal stability of this Organo-Montmorillonite (OMMT) were characterized using X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy and Thermogravimetric … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 9,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Different Ages of a Rehabilitated Forest on Selected Physico-chemical PropertiesRajeswari A.P. Murugayah, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: This research was important because of still lack of information about rehabilitated tropical forest age effect on infiltration rate. The objectives of this study were to determine the influence of age of forest on soil water infiltration rate and to evaluate the influence of forest age on the relationship between water infiltration rate, soil organic matter and soil … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metal Mobility in Polluted Soils: Effect of Different TreatmentsMarta Susana Zubillaga, Emiliano Bressan, Raúl Silvio LavadoThe effects of biosolid compost and phytoremediation applied on the leaching of cadmium, copper, lead and zinc, through the different horizons of a superficially polluted soil were determined. The soil was from the Province of Buenos Aires, Argentina. It was contaminated with cadmium copper, lead and zinc. Leaching columns were used with three different horizons: A: 0.12 m A horizon, … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,136 accessesView PDFCite
