    Geofractionation of heavy metals and application of indices for pollution prediction in paddy field soil of Tumpat, Malaysia
    (Springer, 2013) Ai Yin Sow; Ahmad Ismail; Syaizwan Zahmir Zulkifli
    The present study investigates the concentration of Pb, Cd, Ni, Zn, and Cu in the paddy field soils collected from Tumpat, Kelantan. Soil samples were treated with sequential extraction to distinguish the anthropogenic and lithogenic origin of Pb, Cd, Ni, Zn, and Cu. ELFE and oxidizable-organic fractions were detected as the lowest accumulation of Pb, Cd, Ni, Zn, and Cu. Therefore, all the heavy metals examined were concentrated, particularly in resistant fraction, indicating that those heavy metals occurred and accumulated in an unavailable form.
