Research ArticleOpen accessEvery word in the titleDetermination of Sediment Profile for 210Pb, Pb, U and Th from Sultan Abu Bakar Dam Due to Soil Erosion from Highland Agriculture Area, Cameron Highlands, MalaysiaZaini Hamzah, Seh Datul Riduan, Ahmad SaatProblem statement: Sultan Abu Bakar Dam in Cameron Highlands act as a catchment’s to accumulate all eroded soil carried by the run off flow through Bertam River, the main river that passes through the highland agriculture area. All suspended solid that carried out by the river contain various kind of hazard potential to the environment. U, Th and Pb are … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 12 Jul 2011 · 7,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractRadiological Risks Assessment of Ogun State Drinking WaterJustina Ada Achuka, Usikalu Mojisola Rachael, Oyeyemi Kehinde DavidThe presence of radionuclides in water constitute health risk to man. The consumption of such water increases the likelihood of incurring cancer. Analysis will enhance the detection of significant radionuclides causing harm to the populace and stimulate remediation. This inferred the radioactivity measurements of twenty (20) well water samples from three industrial cities of Ogun State using Hyper Pure Germanium … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 18 May 2017 · 7,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Diatom Stratigraphy of Rawapening Lake, Implying Eutrophication HistoryTri Retnaningsih Soeprobowati, Suwarno Hadisusanto, Peter Gell, Atun ZawadskiProblem statement: The use of diatoms to reconstruct past ecological conditions in lakes is well established. Diatoms are microscopic algae that forms siliceous frustules which allow them to preserve well in sediments. Rawapening Lake is one of 15 Indonesian lakes identified as 2010-2014 National Priority Lakes. Naturally, Rawapening is a tectono-volcanic lake. In the early 1900s, the sole outlet of … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 15 Jun 2012 · 7,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractForest Fires and Resuspension of Radionuclides into the AtmosphereFernando P. Carvalho, Joao M. Oliveira, Margarida MaltaProblem statement: Forest fires are especially frequent around the Mediterranean Sea basin in the summer period and might be able to release naturally-occurring and man-made radionuclides from plant biomass and inject them into the atmosphere. The impact of this radioactivity on populations was not investigated before. Approach: Radionuclide analysis was performed in plants, in smoke from plant burning and in … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 14 Jan 2012 · 7,352 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecent Sedimentation Rate and Sediment Ages Determination of Kemaman-Chukai Mangrove Forest, Terengganu, MalaysiaB.Y. Kamaruzzaman, M.C. OngTwo 20 cm sediment cores were collected with a D-section corer in the Kemaman-Chukai mangrove forest and analyzed for 210Pbex (excess 210Pb) in order to understand the sedimentation pattern. The activities of 210Pb along with the 208Po tracer were measured by Alpha Spectrometry on a silicon surface barrier detector connected to a multi channel analyzer. Sedimentation rates were determined applying … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 9,303 accessesView PDFCite
