Research ArticleOpen accessIn the abstractGlomalin Production and Microbial Activity in Soils Impacted by Gypsum Mining in a Brazilian Semiarid AreaAdalia Cavalcanti do Espírito Santo Mergulhao, Helio Almeida Burity, Fabio Sérgio Barbosa da Silva et al.Problem statement: Mining activities involve the removal of the vegetal cover and the soil organic layer, causing a severe environmental impact. In Northeast Brazil, 40% of the world’s crude gypsum is found in a semiarid area, making this region responsible for 95% of the gypsum demand in the national market. Although economically important, this activity is harmful to the environment. … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 11 Nov 2010 · 9,023 accessesView PDFCite
Research ArticleOpen accessIn the abstractMountain Sheep: An Environmental Epidemiological Survey of Variation in Metal Exposure and Physiological Biomarkers Following Mine DevelopmentLawrence K. Duffy, Michael W. Oehler, R. Terry Bowyer, Vernon C. BleichProblem Statement: Anthropogenic activities, such as mining and industrial operations, are a major environmental source of metal exposure for wildlife. Quantitative data regarding biochemical effects of exposure to mineral extraction on mountain sheep, Ovis canadensis, are limited, although their habitats are becoming increasingly affected by expanded resource development. Decisions relating to environmental protection and wildlife conservation should be based on … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,654 accessesView PDFCite

Research ArticleOpen accessIn the abstractSimulation Model for Feasibility Studies on Bioremediation of Uranium Mill Tailings using Hyper Accumulator Chrysopogon zizanioidesH. Shanmugasundaram, Sathesh Kumar Annamalai, Kantha Deivi Arunachalam et al.Contamination of environment by uranium is expected in places where mining of uranium ore and processing, nuclear testing and reactor operations when the control measures are not effective. The daughter radionuclides of the ores, chemical additives and residual uranium are the maincomponents of processed waste from uranium industries. The bioremediation of contaminated areas using plant species or group of the … …American Journal of Environmental Sciences, Vol. 12, Issue 6 · 11 Dec 2016 · 8,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Classification Techniques on Fused Optical and SAR Images for Shoreline Extraction: A Case Study at Northeast Coast of Peninsular MalaysiaSyaifulnizam Abd Manaf, Norwati Mustapha, Md Nasir Sulaiman et al.Shoreline is a very important element to identify exact boundary at the coastal areas of a country. However, in order to identify land-water boundary for a large region using traditional ground survey technique is very time consuming. Alternatively, shoreline can be extracted by using satellite images that minimizes the mapping errors. The trend of extracting shoreline has been shifted from … …Journal of Computer Science, Vol. 12, Issue 8 · 27 Oct 2016 · 7,708 accessesView PDFCite
