A review on phytoremediation of organic contaminants

Abstract

Abstract: 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.

Key words: Organic contaminants, Plant uptake, Ecotoxicology, Phytoremediation, root system distribution, straw amendment, water stress, straw amendment approach
