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.

0224561阿尔瓦雷斯多环芳烃(PAHs)是一种普遍存在的污染物，可在生物中积累，并可能具有剧毒。一些植物可以通过刺激植物根区(根际)的微生物活动来促进多环芳烃的降解。这种植物修复过程在气候条件有利的地方是一个诱人的过程，比如在热带地区。将对热带植物的根分泌物进行筛选，以确定其促进多环芳烃降解的能力，并研究其促进机制。多环芳烃在土壤中的腐殖化和封存将作为一种可接受的低成本处理方法进行研究。
