Abstract
Phytoremediation of polycyclic aromatic hydrocarbons (PAHs) is inconsistent and the microbial mechanisms involved are unclear. We evaluated the effect of annual ryegrass (Lolium multiflorum Lam.) and P availability on the degradation of pyrene (600mg kg-1 dry soil) in the top 7.5-cm of a Cecil sandy loam (fine, kaolinitic, thermic Typic Kanhapludults) over a 10-month experiment under field conditions in Clemson, SC. Changes associated with the soil microbial community were also evaluated. Plastic canopies were installed to prevent leaching and raindrop dispersion of pyrene. Treatment factors were pyrene, vegetation, and available P levels in a complete factorial experiment with four replications. The soil was adjusted to an average of 42 or 66 kg extractable Pha-1.
