摘要:	Ryegrass (Lolium perenne) and alfalfa (Medicago sativa) were planted in pots to remediate pyrene contaminated quartz sand (as a control group), alluvial and red soils amended with and without compost. The pyrene degradation percentages in quartz sand, alluvial soil, and red soil amended with compost (5%, w/w) and planted with ryegrass and alfalfa for 90 d growth were 98-99% and 97-99%, respectively, while those of pyrene in the corresponding treatments amended without compost but planted with ryegrass and alfalfa were 91-96% and 58-89%, respectively. Further, those of pyrene in the respective treatments amended with and without compost but unplanted were 54-77% and 51-63%, respectively. Pyrene contents in both roots and aboveground parts of ryegrass and alfalfa after 90 d growth in quartz sand and the two soils amended with or without compost were trace amounts. Statistical analyses for the parameters of ryegrass planted in red and alluvial soils including the concentrations of total water-soluble volatile low molecular weight organic acids, microbial population, pyrene degradation percentage, and spiked pyrene concentration show significant correlations at 5% and mostly 1% probability levels, by the analysis of variance. It was thus suggested that the interactions among the consortia of plant root exudates, microorganisms, and amended compost in rhizosphere soils could facilitate bioavailability of pyrene and subsequently enhance its dissipation.
