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-MS was used to investigate the fate of anthracene in the rhizosphere of ryegrass in a spiked soil with or without inoculation with...
We demonstrate that the ion probe technique of time of flight-secondary ion mass spectrometry (ToF-SIMS) is capable of identifying purified organic compounds in situ and could augment GC-MS analysis on small geological samples. ToF-SIMS has been applied to a number of purified organic compounds including polycyclic aromatic hydrocarbons, nitrogen-containing heterocyclics, n-alkanes and isoprenoids...
