Assessment of heavy metals uptake and translocation in Acacia mangium for phytoremediation of sewage sludge contaminated soil

Nik M. Majid, . and M.M. Islam, . and Lydia Mathew, . (2011) Assessment of heavy metals uptake and translocation in Acacia mangium for phytoremediation of sewage sludge contaminated soil. [Proceedings Paper]

An experiment was conducted to evaluate the potential of Acacia mangium as a phytoremediator to absorb heavy metals from sewage sludge contaminated soils. Acacia mangium seedlings were planted on six different growth media were: 100 soil 80 soil20 sludge 60 soil40 sludge 40 soil60 sludge 20 soil80 sludge and 100 sludge. The highest growth performance such as height basal diameter and number of leaves was found in 40 soil60 sludge. Cadmium and lead were highly concentrated in the stems while chromium and copper in the roots. A. mangium seems to have a high potential to absorb much amounts of Cd Pb Cr and Cu in the leaves stems and roots. A. mangium was able to tolerate and accumulate high concentrations of heavy metals. The roots of A. mangium were found to be suitable for the absorption of heavy metals in contaminated soils. Therefore this species can be a good efficient phtyoremediator for sewage sludge contaminated soil.

The highest growth performance such as height basal diameter and number of leaves was found in 40 soil60 sludge. Cadmium and lead were highly concentrated in the stems while chromium and copper in the roots.

The roots of A. mangium were found to be suitable for the absorption of heavy metals in contaminated soils. Therefore this species can be a good efficient phtyoremediator for sewage sludge contaminated soil.
