Analysis of Petroleum-Contaminated Soils, Treatment Using Selective Ornamental Plants

Sufyan Husham Al Samman


Pot-culture trials were completed to survey the phytoremediation capability of 14 elaborate plants in weathered petroleum-debased soil, which was gathered in the Oil Field, one of the greatest oil fields in Iraq, by looking at their effect on the corruption capability of aggregate petroleum hydrocarbons (TPHs) and its arrangement. Comes about indicated Gaillardia aristata, Echinacea purpurea, Fawn (Festuca arundinacea Schreb), Fire Phoenix (a consolidated F. arundinacea), and Medicago sativa L. could viably lessen TPHs and its creation in 10,000mg kg−1 TPH-sullied soil. Following a 30-day pot-culture analyze, the expulsion rates were 37.16%, 46.74%, 49.42%, 41.00%, and 37.93%, separately, essentially higher than that in the control (just 12.93%). Expulsion rates of TPH sythesis including immersed hydrocarbon, fragrant hydrocarbon, asphaltene, and polar compound achieved 39.41%, 38.47%, 45.11%, 42.92%, and 37.52%, individually, additionally higher than that in the control (just 6.90%). Advance, the aggregate biomass did not essentially diminish for all plants tried in 10,000mg kg−1 TPH-debased soil. Fourier change infrared spectroscopy affirmed the nearness of oil in the plant tissues. These outcomes proposed that the run of the mill fancy species including G. aristata, E. purpurea, Fawn, Fire Phoenix, and M. sativa can be embraced in phytoremediation of oil-contaminated soil.
