Preliminary study on Copper, Zinc and Iron concentration in soils from waste dumping site in Tanah Merah, Kelantan, Malaysia

Soil is a complex matrix and a major reservoir of contamination. It can bind many potential toxicelements such as heavy metals, and they can exist in various forms. The main objective was tocharacterize the soil sample in relation to heavy metal concentrations in the Tanah Merah wastedumping site. Soil samples were taken from three different locations around the waste dumping siteand determined by Atomic Absorption Spectrophotometry (AAS) for Cu, Fe and Zn determination.High concentrations of Fe (9.18 mg/L) as compared to Cu (0.53 mg/L), and Zn (0.49 mg/L) werefound in the soil samples but were lower than previous studies. However, early precautionaryactions need to be implemented since a higher volume of waste disposal in the future might causechanges in heavy metals intensity at the waste dumping site.
