| Abstract | ||
| The present study was conducted in the field of medicinal plants belong to College of Agriculture / University of Basra in the growing season 2013 - 2014 to find out the efficiency of phytoremediation using Indian mustard Brassica juncea (L.) Czern in soil contaminated with lead to identify the range of plant tolerance to toxicity and its efficiency to absorb lead.Four concentrations of lead were used in the experiment 0, 100, 200 and 300 mg.kg-1 . Effect of lead on vegetative growth characteristics of Indian mustard was noticed where plant height , leaf area , dry weight of shoots and roots and total chlorophyll were affected , but the plant expressed resistance to the toxicity.The results show accumulation of lead by plant where treatment with concentration 300 mg.kg-1 Pb was significantly higher where accumulation was 750.2 mg.kg-1, while the highest efficiency of phytoermediation for contaminated soil with lead was 27% at a concentration of 100 mg.kg-1. The highest value of bioconcentration factor (BCF) was at concentration of 100 mg.kg-1 where it reached 5.1 as well as the translocation factor (TF) at the same treatment reached 1.3. | ||
