Abstract

Phytoremediation is an alternative to other technologies for the clean up of petroleum contaminated soil. Ten vegetatively propagated cultivars of bermudagrass were examined for their potential to reduced oil sludge contaminated in soil and select the most efficient cultivar. Soil was mixed with different rates of oil sludge (0, 10, 20, 30, and 40% (w/w) to obtain 0, 2, 4, 6, and 8% total petroleum hydrocarbons (TPHs). Ten cultivars of bermudagrass were planted in pots filled with respected mixtures of soil and sludge. Shoot and root weights and percent reduction in the contamination level were measured after six months. Shoot weight reduced as contamination level increased. The root weight increased up to 6% TPHs level. As contamination level increased, the percent reduction in contamination increased. Reduction was 37.7, 41.0, 35.0, 34.0, 45.0, 41.3, 34.5, 41.3, 34.5, 41.3, 55.0, and 43.6% under Tifdwarf, Tifgreen, Tifway, ISF1, ISF2, JP1, JP2, and Midlawn, 3200W18-4 and 3200W19-9 at the highest contamination level 3200W18-4 was the most effective cultivar followed by ISF2, 3200W19-9, JPI, and Midlawn, respectively. The results suggested that bermudagrass is an efficient species for phytoremediation of petroleum contaminated ...Continue Reading
