摘要
A method for remediating soil which is contaminated by an individual or a mixture of Cd and Pb with a hyperaccumulator Emilia sonchifolia L. includes steps of: planting seeds or seedlings of Emilia sonchifolia L. in soil which is contaminated by an individual or a mixture of Cd and Pb; watering regularly to maintain the soil moist; after Emilia sonchifolia L. flowers or completely matures, removing all of or an aboveground part of the plant from a contaminated spot of the soil and disposing the removed plant properly; repeating the above steps until a Cd and Pb content of the soil fall within an environmental security standard. Besides being adaptable and widely available, the Emilia sonchifolia L. is both a Cd hyperaccumulator and a Pb hyperaccumulator by respectively satisfying four indexes of the Cd hyperaccumulator and the Pb hyperaccumulator.
