“…The PAH content in maize shoots was not detected and translocation of ash-PAHs found in roots to the shoots remained unconfirmed. This was in line with the study by Gao et al (2011) who indicated that the spiked PAHs are accumulated in roots rather than transported through the xylem flow to the shoots. In this study, the PAH removal of ash origin from soil by maize roots was negligible in a range between 0.02-0.04% (Table 3).…”

Phytoremediation using maize (Zea mays L.) assisted by the compost or vermicompost amendments was the most appropriate strategy for bioremediation of soil contaminated by polycyclic aromatic hydrocarbons (PAHs) derived from biomass fly ash. Higher removal of low molecular weight PAHs than medium and high molecular weight PAHs within the same treatment were observed. The total PAH content in planted soil with compost or vermicompost was decreased in a range between 62.9–64.9%. There were no significant differences (P < 0.05) between the compost and vermicompost amendments on the total removal of ash-PAHs. The content of PAH derived by ash did not have adverse effect on maize cultivation and biomass yield. The contribution of PAH reduction by maize roots on the soil total PAH removal was negligible. Therefore, maize significantly boosted the PAH removal in soil. The harvested maize shoots did not represent any environmental risk.

“…Therefore, it appears that the effects of mycorrhizal fungi colonization of plants in contaminated soil are positive. Plants colonized by mycorrhizal fungi not only exhibit increased plant survival, but also resistance to toxic pollutants (Gao et al 2011).…”

The purpose of this study was to investigate the effect of phytoremediation on soils contaminated with heavy crude oil using plants infected by mycorrhizal fungi. Five plant species, Vetiveria zizanioides, Bidens pilosa, Chloris barbata, Eleusine indica, and Imperata cylindrica, infected with the species of mycorrhizal fungi Glomus mosseae, were selected for this study. The degradation of total petroleum hydrocarbons in soils and several physiological parameters of plants such as shoot length and biomass were analyzed. Out of the 5 plant species tested, only V. zizanioides, B. pilosa, and E. indica could take up the G. mosseae. Out of these three, V. zizanioides showed the greatest growth (biomass) in soils with 100,000 mg kg -1 total petroleum hydrocarbons. In addition, B. pilosa infected with G. mosseae was found to be able to increase degradation by 9 % under an initial total petroleum hydrocarbons concentration of 30,000 mg kg -1 in soils after 64 days. We conclude that plants infected with mycorrhizal fungi can enhance the phytoremediation efficiency of soils contaminated with high concentrations of heavy oil.

“…Phenanthrene and pyrene in plant samples were extracted and analyzed according to the procedure described by Gao et al (2011). Briefly, 0.5 g plant samples were extracted by ultrasonication for 1 h in a 1:1 (v/v) solution of acetone and hexane.…”

“…Cadmium is relatively mobile in soil and is readily taken up by plants through membrane transporters for essential nutrients, such as Fe, Zn and Ca (Zheng et al, 2011). In contrast, plant uptake of hydrophobic organic chemicals, such as PAHs, could be described as partitioning between the soil aqueous solution and plant roots, with translocation of PAHs from root to shoot being highly restricted (Gao et al, 2011).…”
