“…It may be difficult to predict rates and extents of chemical degradation at contaminated sites based on laboratory studies. One possible step toward resolving this difficulty appeared in a study by Ferro et al (1999), that compared the degradation of creosote-contaminated soil in greenhouse studies to field studies using perennial ryegrass. Significant degradation of PCP, fluoranthene, pyrene, chrysene, and benzo(k)fluoranthene occurred in greenhouse studies.…”

“…The authors normalized the data by transforming the detected concentrations of each contaminant into ratios of the measured contaminant over the concentration of the sum of recalcitrant PAHs (benzo(b)fluoranthene, benzo(a)pyrene, benzo(g,h,i)fluoranthene, and indeno(1,2,3-cd)pyrene). The calculation of ratios using a composite denominator could reduce spatial variability of field-contaminated soil and possibly enable the monitoring of degradation in the field (Ferro et al, 1999).…”

A phytotoxicity bioassay was used to select plant species for phytoremediation that were able to germinate and grow in petroleum-contaminated soil from an industrial site in Canada. Perennial ryegrass (Lolium perenne var. "Affinity") and alfalfa (Medicago sativa L.) were more successful at germination and root growth than were little bluestem (Schizachyrum scoparium) and crown vetch (Coronilla varia). The phytotoxicity assay provides a rapid, efficient mechanism of prescreening potential plant species and eliminating those not able to germinate and establish in soil conditions present at the contaminated site. This bioassay can potentially reduce the number of pot or greenhouse degradation studies that need to be conducted before plant species can be chosen for petroleum phytoremediation.

“…Reilley et al (1996) demonstrated that pyrene degradation rates increased in rhizosphere soil. Roots provide additional carbon to the soil for metabolism and also provide increasing oxygen availability through root channels (Ferro et al, 1999). Loehr and Webster (1996) used land-farming for contaminated soil treatment from a creosote wood treatment site for 18 months, followed by establishment of a warm season grass after two growing seasons In the plots with grass, an additional 81% reduction in total polyaromatic hydrocarbon concentration was reported.…”

“…Phytoremediation, the use of plants to degrade or remove contaminants, has been shown to be effective for petroleum (Reilley et al, 1996;Ferro et al, 1999;Liste et al, 1999;Lalande et al, 2003). Root exudates may provide a source of carbon and energy for microbes, stimulating metabolism and/or co-metabolism of contaminants.…”

Petroleum contamination poses a significant threat to environmental ecosystems worldwide. Phytoremediation can be used to enhance degradation of petroleum contaminants in soil. However, selection of plants for phytoremediation has proven to be complicated. This research examines the heritability of the alfalfa cultivar Riley for phytoremediation based on parental total petroleum hydrocarbon (TPH) degradation after twelve months of growth. Traits other than degradation potential, such as root and shoot yield, height, and maturity, were examined for use as selection traits. Riley showed moderate to low heritability that suggests the possibility of breeding for phytoremediation efficiency. In addition, root and shoot yield were found to correlate to TPH degradation. Crosses in which the female parent was typically associated with low TPH dissipation yielded progeny that were high efficiency TPH degraders.

“…[9−14] Soil vegetated with perennial ryegrass resulted in significantly lower PAHs and pentachlorophenol concentrations when compared to unvegetated soil. [15] This may be due to enhanced aeration of the soil layer, higher moisture content of rhizosphere soil, increased microbial activity near the root, and the presence of organic acids and other root exudates. [16,17] It has been demonstrated that easily degradable organic matter in the rhizosphere reduced the amount of pyrene removed from soil.…”

Biodegradation of organic contaminants in soil may be enhanced by the presence of vegetation. Evaluating the effect of soil depth on phytoremediation efficiency may provide researchers and regulators with a clearer understanding of contaminant clean-up. A column study with polycyclic aromatic hydrocarbons (PAHs) and diesel-contaminated soil was conducted over a 147-day period of switchgrass (Panicum virgatum) growth. Analysis of the contaminants and plant biomass was conducted along with microbial enumeration at three soil depths in 49-day intervals. Remediation proceeded rapidly near the surface of the soil (0-20 cm) for both vegetated and unvegetated columns, but the effect of vegetation relative to an unvegetated control only was significant in the lower soil depths. Contaminant dissipation in the 20-40 and 40-60 cm layers was not significantly different between vegetated and unvegetated soil.
