Main mechanism and affecting factors of phytoremediation of organic contaminated soil

Abstract

Abstract: In this paper, the main mechanisms of phytoremediation of organic contaminated soil, such as adsorption and degradation in rhizosphere, plant uptake, and transformation, and phytoremediation model were illuminated in detail, and their affecting factors, including properties of pollutants, plant species, soil properties, coexisted pollutants, and climate conditions were analyzed.The main topics that need further research were prospected, e.g., deepening the mechanism of phytoremediation, consummating phytoremediation models, approaching on the mechanism and appliance of microbe associated phytoremediation systems, building efficient surfactants enhancing phytoremediation systems, and strengthening the research on phytoremediation of combined organic pollution.

Key words: Phytoremediation, Soil, Organic pollutants
