Pengambilan Logam Berat oleh Terung Pipit (Solanum torvum) dalam Tanih Ultrabes di Kuala Pilah, Negeri Sembilan

This study was carried out at an ultrabasic area, Selaru and Felda Rokan Barat, Kuala Pilah, Negeri Sembilan. Eighteen samples of plant and its substrates were collected for determination of heavy metal contents such as Ni, Co, Cr, Mn and Fe in soils and plants. The plants were separated into different portion such as root, stem and leaf and extracted for their heavy metal content by wet digestion method whereas the soils heavy metal available and resistant content were extracted by sequential extraction. Heavy metals content in soil and plant extract was determined using Flame Atomic Absorption Spectrophotometer. The result showed that total content of heavy metals for Ni, Cr, Co, Mn and Fe was at 84.13 - 740.36 mg/kg, 23.51 - 135.53 mg/kg, 188.23 - 848.92 mg/kg, 245.00 - 545.33 mg/kg and 1176.77 - 1243.90 mg/kg, respectively. Bio-available heavy metals content in soil is at 0.09-6.32 mg/kg for Ni, 0-0.51 mg/kg for Co, 0 mg/kg for Cr, 7.78-21.07 mg/kg for Mn and 2.23-4.47 mg/kg for Fe. Based on BAC, Mn and Fe were detected to have a high concentration in plant parts compared to other heavy metals
