Abstract

The increasing heavy metal pollution in the sugarcane soil along the Huanjiang River was caused by leakage and spills from Pb and Zn tailing dams during a flood event.A 12-month experiment was conducted in the farmland with contaminated soil to evaluate the potential of sugarcane for remediation of soil contaminated with As, Pb, Cd, Cu, and Zn. Total and available heavy metal concentrations in the contaminated soils were analyzed before and after the phytoremediation application. The heavy metal concentration with phytoremediation was reduced compared with no sugarcane treatments. Elements showed low mobility, which was related to their total concentration in soil. Cu and Zn exhibited the greatest potential for release and thus for transporting to non-contaminated areas. The situation of Pb and Cd was intermediate. Heavy metal concentrations in the sugarcane juice were all below the maximum for contaminants in food, but that in bagasse met the maximum of standard. Sugarcane phytoremediation reduced the trace element availability and the risk of entry into the food chain. This technique is cheaper than other methods and proved to be a successful and reliable technique for remediation of large-scale trace element-contaminated soil with minimum maintenance.
