英文摘要
0224561 Alvarez Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous pollutants that can bioaccumulate and can be acutely toxic. Some plants can enhance the degradation of PAHs by stimulating microbiological activity in the root zone (rhizosphere) of plants.This phytoremediation is an attractive process where climatic conditions are favorable as in the tropics. Root exudates from tropical plants will be screened for their ability to enhance PAH degradation and the mechanism of enhancement studied. The humification and sequestration of PAHs into soil will be examined as an acceptable low-cost treatment.
