Phytoremediation of Agricultural Land Polluted with Heavy Metals in Wadi-Alsamin- Hebron.
Land Research Center Presented By: Murad Alhousani
Project Title: Soil Pollution Treatment in Wadi AlsaminHebron Area Implemented By: Land Research Center. Supervised By: Berziet University Dr. Jamil Harb Funded By: GEF /SGP/UNDP (Ref.No. PAL10 _ 71645)
LRC Profile: Palestinian NGO, Non - Profit established in 1986 as part of Arab Studies Society. Programs: 1. Human Right Program . 2. Natural Resource Management Program. 3. Researches & Studies Program .
WW stream pass through: 18 Palestinian communities
Wastewater Stream Length: 44 km Width: 10 â€“ 20 m Affect: 6,846 Agricultural Dun.
Wastewater Stream Sources: 1. Palestinian Domestic Wastewater 2. Palestinian Industrial Wastewater 3. Wastewater from Israeli Settlements
Wastewater stream daily discharge 13,000 m3
Research Objectives To evaluate the pollution level by heavy metals in the polluted soil. To investigate the extent of plant efficiency in remediation of the polluted soil in the study area.
Material & Method
Methodology 1.Field Survey. Including â€œ Soil Analysisâ€?. 2.Selection of Local Phytoremediation Plants. 3.Experimental Design. 4.Measurements of Heavy Metals. 5.Data Analysis.
1. Field Survey, Including “ Soil Analysis” • • • •
Interviews with Stakeholders. Determination of Targeted areas. Soil Sampling. Measurements of Heavy Metals Content.
2. Selection of Local Phytoremediation Plants • Corn and Tobacco were selected according to : • Literature review • Local Varieties
3. Experimental Design
Experimental Design â€“ Ex. Of Field Plot
4.Measurements of Heavy Metals “Soil & Plant”
5. Data Analysis
1. Heavy metals content in Soil (mg/kg) 10 – 50
300 – 1000

Conclusion • Corn plant is more efficient for extraction of Cr, and Ni metals, whereas the tobacco plant is better for Mn metals. • This study clearly confirm that cultivation of soil exposed to untreated wastewater effluent lead to bioaccumulation of toxic metals in edible crops. • Further studies are still necessary for improving phytoremediation of polluted soil.
