Evidence for simultaneous abiotic-biotic oxidations in a microbial-Fenton's system
Article Abstract:
In situ bioremediation has been effective in eliminating petroleum hydrocarbons and other reduced contaminants under aerobic conditions, and is used as a treatment for contaminated groundwater and soil. An investigation was conducted on the conditions that support the simultaneous activity of the heterotrophic aerobic bacterial metabolism and the hydroxyl radicals by using tetrachloroethene and oxalate. Results showed that in the presence of hydroxyl radicals, heterotrophic bacterial metabolism may occur.

Reactivity of Pb(II) at the Mn(III,IV) (oxyhydr)oxide-water interface
Article Abstract:
Remediation strategies which target reducing the solubility and toxicity of lead (Pb(II)) are being developed because of environmental worries over Pb(II) contamination in aquatic settings, soils and sediments. This study used kinetic, thermodynamic and spectroscopic investigations to evaluate the reactivity of lead (Pb(II)) on naturally occurring manganese (Mn(III,IV)) (oxyhydr)oxide minerals. The results from the study have a major impact on Pn partitioning in soil environments containing solid-phase Mn(III,IV) (oxyhdr)oxides.

Predicting the wettability of quartz surfaces exposed to dense nonaqueous phase liquids
Article Abstract:
The efficacy of using remediation to lower subsurface contamination by dense nonaqueous phase liquids (DNAPLs) is dependent on its distribution in the porous medium. This study used a model incorporating electrostatic and van der Waals forces to predict the wetting behavior of multiple systems containing a quartz surface, water and a DNAPL.
