TL;DR: In this article, the decontamination of perchlorate-contaminated water by woody plants was investigated in sand and hydroponic bioreactors, and two phytoprocesses were identified as important in the remediation of per-chlorate contaminated water: uptake and phytodegradation of per chlorate in the tree branches and leaves and rhizodegradation.

TL;DR: In this article, data obtained from batch kinetics sorption experiments for naphthalene and diuron using two organoclays in aqueous and methanol−water systems were analyzed with a first-order one-site mass transfer model (OSMTM) to obtain kinetic parameters.

TL;DR: The faster dechlorination rate of PCE observed with dithionite-reduced Fe-poor montmorillonite than similarly reduced iron-rich ferruginous smectite suggests that the use of dithionsite barriers for in-situ treatment of chlorinated solvent plumes should not be limited to aquifers with Fe-rich sediments.

TL;DR: Four phytoprocesses were found to be important in the removal of the probe HOCs from water by aquatic and terrestrial plants, namely, rapid sequestration by partitioning to the lipophilic plant cuticles; phytoreduction to less halogenated metabolites; phytooxidation to haloethanols, haloacetic acids, and unidentified metabolites; and assimilation into the plant tissues as nonphytotoxic products.

TL;DR: In this article, the authors show that methyl bromide is reactively removed from air by the foliage of all 9 herbaceous, 18 deciduous, and 12 coniferous plants in a process that appears enzymatic.
