Abstract. The study assessed the concentration of heavy metals in soil and plants around a quarry site in Southwestern Nigeria. Sample plots were established in a systematic method along a line transect at increasing distance of 1, 50, 100, 150, 200, 250 and 300 m from the quarry processing plant.
The impact of previous operations on the environment was assessed by determining heavy metal contents of soil (topsoil, 0-15 cm and subsoil,15-30 cm) and plant samples taken at 0, 10, 15, 30, 60, 120 and 200 m from an abandoned granite quarry and compared to samples from a control (baseline) location. Fe was the most abundant element in the
