Potential Toxic Elements Distribution Based on Interplay between Pollutants and Biochemical Remediative Amendments
Abstract
The aim of this work is to measure in field experiment the distribution
of potential toxic elements PTE's Cu, Ni and Zn in sewaged soil after
application of chemical remediation technique represented by probentonite,
bioremediation technique as thiobacillus thiooxidant, Mycorrhyzal (AM) conidia,
and mixture of this treatments (PBC) applied before the plantation of Canola
(Brassica Napus, L.), Indian Mustard (Brassica juncea Czern.) and Black
nightshade (Solanum nigrum L) as a hyper accumulated plants. The obtained
results showed that phytoremediation technique applied individually increased
the readily available form after remediation arranged as canola> black
nightshade> Indian mustard, meanwhile the application of Probentonite with
phyto-accumulation plants increased the residual form in soil system. In the
case of bioremediation materials applied, data showed decreasing in both
readily and hardly available forms with margin increasing in moderately
available forms. The final conclusion of this work documented as the
application of PCB technique could be the best management practices in
minimizing Zn equivalent to the save level. Different mechanisms of the
remediation materials actions were discussed.
