Accumulation of Cu, Cd, Cr, Mn and Pb from artificially contaminated soil by Bacopa Monnieri

摘要: The metal accumulation potential of Bacopa monnieri L. was assessed under simulated laboratory conditions. This study carried out in mixed metals (Cu, Cd, Pb, Cr, Mn) condition and repeated exposures artificial contaminated soil. growing shoots were planted garden subsoil containing 3, 16, 32, 64, 160 μM each the above metals. After 8 weeks, plants refeeded to three times higher concentrations than initially used assess maximum accumulating by root shoot concentration duration dependent. considerably fine showed following order : Mn > Cr Cu Cd Pb. high tolerance as no visible phytotoxic symptom produced after weeks. However, a result combined toxicity, chlorophyll content reduced 62% 12 highest lethal plant at 16 In view their tolerance, B. may be considered for amelioration industrially-polluted wetlands experiencing regular flushing wastewaters.
