摘要
多环芳香烃(PAHs),三硝基甲苯(TNT)和有机农药等有机物残留在土壤,水体和大气中,造成了严重的环境污染。应用植物清除这些有机污染物是治理环境污染的一项有效途径。在此,介绍了清除各类有机污染物的植物种类,作用机制,效益评估及其研究进展,并讨论了植物修复面临的挑战和应用前景。
Many organic pollutants including trichloroethylene （TCE）, polycyclic aromatic hydrocarbons （PAHs）, 2,4,6-trinitrotoluene （TNT） and pesticides resided in the soil, water and air, resulting in the large environment pollution. Phytoremediation of organic pollutants has been recognized as a low-cost and highly efficient approach for cleaning up environmental contamination. In present paper, we focus on describing the important aspects of the phytoremediation such as plant species, acting mechanisms, efficiency evaluation and recent achievements. Furthermore, we also discuss the challenge and perspective of the phytoremediation of organic pollutants.
