Sequential Extraction of Cu, Cd, Pb and Zn from Soil Around Industrial Waste Dump Sites in Kaduna Environ using Simple and Sequential Procudures

Abstract

The presence of heavy metals in soil around industrial wastes dump sites restricts their use for agricultural purpose. This study attempts to extract Cu, Cd, Pb and Zn from soils around some selected industrial wastes dump sites in Kaduna. Four dump sites were identified namely Kudenda, Kakuri, Gonigora and Dirkaniya. Some agronomic parameters necessary to characterize a soil were determined. The simple sequential procedure was use for the extraction. It was confirmed from the study that the metal content of these metals did not exceed the limit by European standard.

Keywords: Cu, Cd, Pb, and Zn, extraction, dump sites.
