Phytoremediation for soil PAHs with several legumes and grasses were investigated using a greenhouse study. The results indicated that eight plant species had different roles in PAHs degradation and removal in soil after 90 days. The removal rates of alfalfa and perennial ryegrass were 48.4% and 46.8%, respectively, and the biodegradation efficiency of 3-ring PAHs was high than those of 4-ring, 5-ring and 6-ring PAHs. The plant species showed different capability in PAHs uptake, accumulation and translocation from soils. Bioconcentration factors (BCFs) of alfalfa and perennial ryegrass were 0.096 and 0.085, but their phytoextraction rates were only 0.017% and 0.013%, respectively. So alfalfa and perennial ryegrassthe have good rhizoremediation potential in PAH-contaminated soil.
