|
The plant extraction known as Phytoextraction is based on the principle of extracting pollutants from polluted soil by a group of plants and collecting them in the form of components (compounds or groups) above the surface of the earth. This study showed when growing juncea Brassica in soil contaminated with lead, it was found that it accumulates a percentage mg / kg 500 Pb according to the dry weight principle while sunflower (Helianthus annus) and corn (Zea mays) can grow in soils containing 16000 mg / kg of lead without any toxic effect according to Vanli (2007) Chehregani vd. (2009) an accumulation of mg / kg 611 Pb was determined in the area of plant roots and mg / kg384 Pb per plant within a short period of time of 3 weeks in soil contaminated with lead, while Hemidesmus indicus was excessive with lead and the rate of accumulation was for Salix cathayana Lithocarpus dealbatus, Sambucus chinensis, Rhododendron decorum 0.23, 0.14, 0.33, and 0.11 respectively. These plants were identified as cumulative plants of pb and Brassica campestris, Brassica Juncea, Dhatura innoxia, Ipomoea carnea, Phragmytes karka, 20 plants were cultivated after application. 50,100, and 200 mg / kg, in a study by Ghosh ve Sink (2005), it was found that in applying Cd 200 mg / kg there was no significant growth of plants while in applying 100mg / kg of Cd, it was found that Brassica Juncea in dry weight accumulates Cd. By (81,9) mg / kg.
