Heavy Metal Release Potential of Selected Dumpsite Waste Streams: Geochemical Evidence and Assessment of Soil Pollution Indices

Bassey U. Udo, Ndifreke I. Udosen, Pamela B. Dominic & Sekerema U. Silas · Asian Journal of Applied Chemistry Research · 2026

The release of potentially harmful metals from waste materials into soil represents a significant pathway for soil contamination. This study quantitatively examined the release potential of metals (Cd, Cr, Ni, Pb, and V) from diverse waste streams at predetermined depths (0–20 cm...
