TLDR
In this paper, 12 organic compounds commonly found at hazardous waste sites were studied for uptake by hybrid poplar trees for phytoremediation, and the translocation and partitioning relationships based on compounds' octanol−water partitioning coefficients (log Kow) produced the best results.Abstract:
Twelve organic compounds commonly found at hazardous waste sites were studied for uptake by hybrid poplar trees. The vegetative uptake of many of these compounds has not previously been demonstrated for plant species being utilized for phytoremediation, such as hybrid poplar trees. Experiments were conducted hydroponically utilizing 14C-labeled compounds to ascertain translocation and fate. Predictive relationships for the translocation and partitioning to plant tissues were developed from the experimental data. Translocation and partitioning relationships based on compounds' octanol−water partitioning coefficients (log Kow) produced the best results, but the relationships did not allow for fully accurate prediction of each contaminant's fate. Translocation and subsequent transpiration of volatile organic compounds (VOCs) from the leaves to the atmosphere was shown to be a significant pathway. As full-scale phytoremediation systems are deliberated, the pathways investigated here should be considered in te...read more

Rhizosphere processes and management in plant-assisted bioremediation (phytoremediation) of soils.
TL;DR: Evaluation of the current literature suggests that pollutant bioavailability in the rhizosphere of phytoremediation crops is decisive for designing phytomediation technologies with improved, predictable remedial success.

Plant uptake of non ionic organic chemicals.
TL;DR: Although a number of predictive models exist using established relationships, these require further validation if they are to be considered sufficiently robust for the purposes of contaminated land risk assessment or for prediction of the global cycling of persistent organic pollutants.

Relationships between lipophilicity and root uptake and translocation of non-ionised chemicals by barley†
TL;DR: In this article, the uptake by roots from solution, and subsequent translocation to shoots in barley, of two series of non-ionised chemicals, O-methylcarbamoyloximes and substituted phenylureas, were measured, Uptake of the chemicals by roots was greater the more lipophilic the chemical, and fell to a lower limiting value for polar chemicals.

TL;DR: Poplar trees were found to be capable of taking up trichloroethylene (TCE) and degrading it to several known metabolic products: trich chloroethanol, trichchloroacetic acid, and dichloracetic acids as mentioned in this paper.
