摘要: The petroleum industry activities provide po- tential risks to the environment because they can con- taminate ecosystems with different organic compounds in production chain. Several accidents transport and handling of related products oc- curred urban areas harmful effects quality life economy. In 1990s, bioremediation phytoremediation technologies as economically feasible alternatives repair environmental damage were developed. this study, potential willows Salix rubens triandra evaluated regard soils contaminated petroleum-derived hydrocarbons (total hydrocar- bons polycyclic aromatic (PAHs)). PAHs quantified by extraction from plants using dichloromethane under ultrasonication. HPLC analysis was performed GC/MSD equipment. total present uncon- taminated soil sum animal/ vegetable oils greases mineral according Standard Methods 5520 (1997). two species S. resistant during project development. soil, which both planted,the hydro- carbons concentration reduced near 98 %. content remarkably well.
