This study determined the concentration of five heavy metals zinc (Zn), iron (Fe), manganese
(Mn), chromium (Cr), and cadmium (Cd) in soil and woody plants species (Azadiractha
indica, Mangifera indica, Andropogon gayanus, Uvarea chamae and Gmelina arborea) at
NIGERCEM, Nigeria. Soil samples were collected at 40, 80, 120, 160 and 500 m sampling
positions. The highest soil concentrations of Zn (212.40 mg/kg), Fe (186.30 mg/kg), and Mn
(68.10 mg/kg) in soil were obtained at 40m while Cd (3.02 and 2.96 mg/kg) and Cr (26.0 …
Abstract
This study determined the concentration of five heavy metals zinc (Zn), iron (Fe), manganese (Mn), chromium (Cr), and cadmium (Cd) in soil and woody plants species (Azadiractha indica, Mangifera indica, Andropogon gayanus, Uvarea chamae and Gmelina arborea) at NIGERCEM, Nigeria. Soil samples were collected at 40, 80, 120, 160 and 500 m sampling positions. The highest soil concentrations of Zn (212.40 mg/kg), Fe (186.30 mg/kg), and Mn (68.10 mg/kg) in soil were obtained at 40m while Cd (3.02 and 2.96 mg/kg) and Cr (26.0 and24. 68 mg/kg) concentrations in soil was statistically equal (P> 0.05) at 40 and 80 m. In plants, the highest concentrations of Zn (18.48 mg/kg) and Fe (33.61 mg/kg) were observed in Andropogon gayanus; Cd (0.13 mg/kg) was in Mangifera indica; while Cr (2.152 mg/kg) and Mn (7.27 mg/kg) was in Azadiractha indica. The concentrations of heavy metals in soil and plants were below toxicity level except for Cd in soil. There were significantly positive correlations between heavy metals in soils and plants.
