1- Background and issue of the heavy metal contamination in soils (Environmental contamination)
2- Background and literature review of using Zero Valent Iron (ZVI) to tread soil contaminated with Heavy Metals (Soil remediation Problem statement and justification)
3- Uptake and accumulation of contaminants by plants after remediation
4- Preliminary bioavailability test of mixed contaminated soil on plants (Effects of contamination on root and shoot length)
5- Plant selection based on a review of the literature on bioavailability test ( For example (Panicum virgatum (switchgrass), Lolium perenne (ryegrass), Avena sativa (oat), Medicago sativa (alfalfa), Brassica juncea (Indian mustard), Helianthus annuus (sunflower) and Festuca arundinacea) were selected because of their tolerance and contaminant removal.
