Immobilization of Heavy Metals in Contaminated Soil using Calcium Phosphate Amendment and Phosphate-solubilizing Fungi (Penicillium sp) in Benin City, Edo state, Nigeria
Abstract:Soil is a limited resource that is continually contaminated by the presence of heavy metals as a result of human activities. This study used a combination of calcium phosphate amendment and phosphate-solubilizing fungi to immobilize heavy metals in polluted soil. Bovine bones were collected at an Abattoir Market in Aduwawa, Benin City, Nigeria with coordinates 6°22’6.24” N and 5°41’0.24” E and calcined to extract calcium-phosphate (hydroxyapatite), serial dilution and plating on Pikovskaya medium were utilized… Show more
