THE ASSESSMENT OF TOLERANCE TO HEAVY METALS (Cd,Pb and Zn) AND THEIR ACCUMULATION IN THREE WEED SPECIES
Abstract
Phytoextraction is gaining great attention as an alternative technique for remediation of heavy metal contaminated soils. A greenhouse study was conducted to assess heavy metal (Cd, Pb, and Zn) accumulation in three weed species viz., Avena sterils, Isatis tinctoria and Xanthium strumarium. A range of phytoavailable Cd, Pb and Zn concentrations in soils was created by applications of five different levels of Cd (0
