C.K. YAP AND I. MUHAMMAD TAUFIK

Abstract

This study determined the concentrations of Cd, Cu, Pb, Ni, Fe and Zn in the four geochemical fractions on the dusts collected from 6 residential sites in Malaysia. The results indicated that a clear elevation of Ni and Cd concentration in which > 87% for Cd and > 96% for Ni were contributed by non-resistant fraction of the dusts, indicating high extractability and mobilization of these metals that could potentially cause toxicological risks to the inhabitants of the residential area.
