Plants can take up and accumulate most persistant chemicals such as PCBs and PAHs by roots. Some chemicals such as TNT, TCE, and most organic pesticides can be phytodegraded into polar metabolites, or assimilated to CO2 and water by some plants. On the other hand, more microorganisms in rhizosphere can enhance the degradation rate of organic contaminants in environment. The benefits and some issues on phytoremediation are also discussed.
植物可以通过根系吸收和积累大多数持久性化学物质,如多氯联苯和多环芳烃。一些化学物质,如三硝基甲苯、三氯乙烯和大多数有机农药,可以被植物降解为极性代谢物,或被一些植物同化为二氧化碳和水。另一方面,根际中更多的微生物可以提高环境中有机污染物的降解率。文中还讨论了植物修复的益处和一些问题。
