Abstract
Remediation of toxic metals. including Pb and other pollutants has been an important research subject for environmental studies. In a complete controlled growth chamber we prepared different Pb treatments and pH values. Four turfgrass species were used in order to study the potential role of species that may play an important role for environmental remediation of contaminated soils, and possible mechanisms of Pb translocation from root to shoot system using kinetic studies.
Results revealed that. after 14 days most of Pb accumulated more in root than shoot. Increasing pH value for one unit particularly at high rate of Pb show that, mean values of the ratio rooVshoot system reached to almost 12 times. Results also indicate that increasing Pb concentration, gradually increased Pb content in both (oat and Shoot. It was noticed that Spartina Patens (D) species, showed higher content of Pb as compared with other Species. Oata showed that increasing Pb concentration up to 500 ppm led to increase the dry matter for both Centipede grass and Buffalo grass. The obtained results also show that rate constant values of ~ were affected by plant species and part of plants as well. Rate of the translocation of Pb from root to shoot parts Showed that increasing pH values from 4.5 to 6.5 led to increase the translocation of Pb from root to shoot.
Our results emphasize that turfgrass can accumulate substantial amounts of Pb and thus could be a major component of such a green liver particularly in urban and Sub urban regions.
