Translocation of metals in pea plants grown on various amendment of electroplating industrial sludge.

A pot-culture experiment was conducted to observe the effects of acidic sludge addition to the soils on bioavailability and uptake of heavy metals in different parts of pea plant as well as its influence on the growth of that plant. It is observed from our result the abundances of total and bio-available heavy metals in sludge vary as follows: Fe>Mn>Cr>Ni>Cu>Pb>Zn>Cd and Fe>Ni>Mn>Cr>Cu>Zn>Pb>Cd. Sludge applications increased both the total metals, DTPA-extractable metals and total N in the soils.
