Abstract
Typha angustifolia L. was planted in situ at Ex-Mamut copper mine at Ranau, Sabah. The planting area receives continuous water flow from the mine pit. The growth and the accumulation of heavy metals in T. angustifolia as well as its anatomical were examined to study the potential of T. angustifolia as phytoremediation in acid mine drainage (AMD). The concentrations of heavy metals in three replicates of plant roots, stems and leaves were determined at 0, 60, 90 and 120 days after planting. The samples of plant tissue analysed by Inductively-Coupled Plasma Emission Spectrometry showed that the highest concentration of iron (15.33 mg/g) was in the root tissues at Day 120 followed by leaves (0.23 mg/g) and stems (0.21 mg/g). The translocation factor values of heavy metals were less than 1, which indicated that the translocation of heavy metals from roots to stem and leaves was not effective. The plant roots were necrosis and the leaves were chlorosis, but the new shoots were grown out at the end of experiment. The analysis of the root surfaces by Scanning Electron Microscope-Energy Dispersive X-ray spectrometry showed that the highest percentage of heavy metal was iron (23.8wt%). A light microscopic study showed the distortion of cell shape in the root. A Transmission Electron Microscope study showed that some granules were deposited around root cell walls. The result shows that T. angustifolia can survive in acidic environments such as at Mamut mine and has characteristics of an excluder species. The results obtained from this research can be used to maximize the potential of T. angustifolia for phytoremediation at Ex-Mamut copper mine.
