Effects of French Bean,Soybean and Mung Bean on Super-accumulation of Heavy Metals

ZHANG Zhu-qing,TAN De-jun (College of Chemistry and Environmental Engineering,Yangtze University,Jinzhou,Hubei 434023,China)  
Three crops,french bean,soybean and mung bean,were tested by the blasto-filtration method and pot experiments to study their effects on the absorption and accumulation of Zn,Cd and Cu.The results showed that the blasto-filtration method could significantly reduce Zn,Cd and Cu concentration in water within 144 h under the test condition and 100mg/L of Zn,Cd and Cu could be decreased to 62.45mg/L,73.98mg/L and 73.4mg/L,to 6.35mg/L,7.25mg/L and 7.45mg/L and 4.5mg/L,3.48mg/L and 4.675mg/L by french bean,soybean and mung bean respectively.The results of the pot experiment showed that french bean,soybean and mung bean all were of the accumulation effect on heavy metals in soils and the BAR of French bean for Zn accumulation and soybean for Cu accumulation was over 1,which indicates that french bean and soybean were of the super-accumulation trend.
