Research ArticleOpen accessIn the abstractPreliminary Tests Concerning Zero-Valent Iron Efficiency in Inorganic Pollutants RemediationSilvia Fiore, Maria Chiara ZanettiProblem statement: This study was aimed to a preliminary evaluation of the applicability of granular Zero-Valent Iron (ZVI) to the on site remediation of groundwater polluted by inorganic contaminants by means of a Permeable Reactive Barrier (PRB). A particular interest was devoted to groundwater impacted by Acid Mine Drainage (AMD) that was caused by the oxidation of metal sulphide minerals … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,790 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhenanthrene Contaminated Soil Biotreatment Using Slurry Phase BioreactorM. Arbabi, M. Sadeghi, Ch. AnyakoraProblem Statement: Polycyclic Aromatic Hydrocarbons (PAHs) are suspected toxins that accumulate in soils and sediments due to their insolubility in water and lack of volatility. Slurry-phase biological treatment is one of the innovative technologies that involve the controlled treatment of excavated soil in a bioreactor. Due to highly soil contamination from petroleum compounds in crude oil extraction and also oil … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,762 accessesView PDFCite
