Phytoremediation is an effective method to remediate soil contaminated with organic pollutants in soil, mainly through plant absorption, rhizospheric-enzyme-stimulated degradation and microbial degradation. This paper discussed in brief the notion of phytoremediation, reviewed mechanisms of the phytoremediation, and findings in the research on using plants to remediate soil contaminated with pesticides, organochlorine compound, polycyclic aromatic hydrocarbons and others organic pollutants and their application, and looked into future of the study for focal points.
