Abstract

The purpose of this study was to investigate the levels of heavy metals in four different soils from agricultural areas namely Cameron Highlands (Pahang), Sepang (Selangor), Bangi (Selangor) and FELDA Chini (Pahang). The soil samples were subjected to a four-step sequential extraction procedure designed to establish the speciation, mobility, availability and the origin of the heavy metals such as lead, cadmium, chromium, cuprum, zinc, iron and manganese. The four fractions corresponding to the selected extractants were termed easily leachable and ion exchange (ELFE), acid reduction (RA), organic oxidation (OO) and resistant (RR) fractions. Generally, most of the metals studied were significantly associated with the RR fraction, followed by the organic oxidation and RA fractions indicating the lithogenic origin and strongly bound metals in the soils. The least average partitioning patterns in ELFE in most sites indicated low heavy metal mobility and availability to plants. Among the metals studied, the availability of Pb, Cd, Zn and Fe was highest in the Sepang soils whereas that of Cr, Cu and Mn was highest in the Cameron Highlands soil. The anthropogenic input of these metals in soils might be due to the application of fertilizers and pesticides in the vegetable farming areas.
