摘要：

It is known that plant rhizospheres can enhance the dissipation of polycyclic aromatic hydrocarbons (PAHs), but the mechanisms involved are not fully understood. The contribution of root symbiotic micro-organisms such as arbuscular mycorrhizal (AM) fungi is not known. GC-R IS was used to investigate the fate of anthracene in the rhizosphere of ryegrass in a spiked soil with or without inoculation with AM fungi. GC-MS allowed us to identify and quantify an oxidation product of anthracene (anthraquinone) in soil. Oxidation of anthracene to anthraquinone was greater in planted than non-planted pots. The concentration of anthraquinone was lower in the mycorrhizal than non-mycorrhizal planted soil. (C) 2001 Elsevier Science Ltd. All rights reserved.
