Abstract :
This study was carried out at an ultrabasic area, Selaru (S1 S2) dan Felda Rokan Barat (S3), Kuala Pilah, Negeri Sembilan. Eighteen samples of plant and their substrates were collected from study area. The purpose of this study was to determine heavy metal such as Ni, Cr, Mn, Co, Fe and Zn contents in soils and different parts of the plant, such as leaf, stem, root and fruit. Biologal Absorption Coefficient (BAC) of the plant was obtained by calculation. Heavy metals content in the plant were extracted by digestion method whereas in soil the heavy metals were extracted by sequential extraction. Heavy metals content in soil and plant extract was determined using Flame Atomic Absorption Spectrophotometer. It was found that heavy metal concentrations in soil substrate for mengkudu (Morinda citrifolia) were high for Fe followed by Cr, Ni, Mn, Zn and Co with average concentration of 1208.5, 583.4, 352.4, 352.4, 70.7 and 53.6 mg.kg-1, respectively. Available Mn and Zn concentrations were higher than the other heavy metals in term of percentage. Fe and Mn were dominant in all parts of plants however in terms of BAC average, Co showed the highest enrichment value in all parts of the plants.
