Phytoattenuation of lead-contaminated agricultural land using Miscanthus floridulus—an in situ case study

AbstractPhytoremediation is the most environmental friendly and economical technology for restoring agricultural land contaminated by heavy metals. However, it is a slow process, requiring hundreds to thousands of years to reduce pollutant level to meet soil environmental quality standards for highly contaminated soils. Such a long period makes the practice of phytoremediation nearly impossible without economic revenue from crop production. Miscanthus floridulus (M. floridulus) is characterized by its high dry matter yield and strong vitality. This case study planted M. floridulus on fallow land that was contaminated by 6,000 mg/kg of lead to investigate the feasibility of phytoremediation. The case study results show that lead accumulated primarily in the roots of the M. floridulus. After one year of growing, the average lead content in the roots and shoots was 806.7 and 50.3 mg/kg, respectively. M. floridulus was effective for the phytostabilization of lead-contaminated soil and was a lead-tolerant plan...
