SGER: Remediation of PAHs in the Rhizosphere of Tropical Plants

[224561]多环芳烃（PAHs）是一种普遍存在的污染物，具有生物积累和急性毒性。有些植物可以通过刺激根区（根际）微生物活性来促进多环芳烃的降解。在气候条件有利的热带地区，这种植物修复是一种有吸引力的过程。对热带植物根系分泌物促进多环芳烃降解的能力进行了筛选，并对其机制进行了研究。多环芳烃在土壤中的腐殖化和固存将作为一种可接受的低成本处理方法进行研究。

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.
