Abstract
Soils in areas of mining operation are used in cultivating crops in Kwara State. This makes it imperative to monitor the concentrations of toxic heavy metals in the soil. The concentrations of Mn, Fe, Cu, and Zn at 10m intervals from the centre of marble quarry were determined up to 110m distance. Values of extractable Mn varied from 1.73 to 10.8, Fe 6.0 to 19.8, Cu 0.55 to 2.8 and Zn from 0.03 to 0.66 mg/kg. The values are suitable for crop production. Keywords: mining, soil, toxic, heavy metals, marble, quarry.
