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.
