Effectiveness of Calcined Calcium Carbide Waste (CCCW) in Mitigating the Leachability of Lead and Cadmium from Contaminated Soil from Evbareke Spare Parts Market Benin City Edo State Nigeria

Heavy metal contamination of soil can present dangers besides threats to humans as well the ecosystem via uninterrupted intake or interaction with contaminated and food chain. The purpose this research is examine effectiveness calcined calcium carbide waste (CCCW) in mitigating leachability lead cadmium ions from Evbareke spare parts market Benin City, Edo State Nigeria. Contaminated samples were collected using quadrant sampling method at depth 0-15cm auger. was obtained a panel beating workshop dumpsite. dried constant weight an oven 105oC. 50g (CCW) crushed mortar obtain powdered form. X-ray diffraction analysis for CCCW revealed that it made up predominantly portlandite (47%), calcite fraction (23.0%), dolomite (12.7%), coesite (8.6%), muscovite (4.5%) lime (4.0%), corroborated by FTIR analysis. SEM possess rough surface pore varied size irregular shape. petroleum hydrocarbons, saline low C.E.C. texture loamy-sand. As amount amended increase soil, releasable reduced. stabilized hence reducing availability soil. optimum amender immobilize ion 4% w/w ≥2% ion. effectively mitigated
