ASSESSING SOIL PHYSICOCHEMICAL TRAITS AND HEAVY METAL LEVELS NEAR KADUNA METROPOLIS INDUSTRIES

Abstract:

The global issue of environmental contamination by heavy metals continues to rise, emphasizing the need for ongoing soil monitoring around industrial areas. This study focuses on the physical, chemical, and heavy metal concentration analysis of soil in the proximity of selected industries within Kaduna metropolis. The mean values for pH, electrical conductivity, % organic matter, % sand, % clay, and % silt were found to be 7.16±0.35, 362.60±10.7 µS/cm, 2.92±0.50, 76.50±0.81, 17.79±5.51, and 6.13±1.65, respectively. The average concentrations of the investigated heavy metals ranged between 26.89±0.36 µg/g and 77.18±0.40 µg/g for Pb, 29.25±0.7 µg/g and 44.20±0.35 µg/g for Cr, not detected (ND) to 1.5±0.02 µg/g for Cd, 134.63±1.10 µg/g to 217.96±0.16 µg/g for Zn, 9.58±0.7 µg/g to 74.45±0.20 µg/g for Cu, 92.14±0.20 µg/g to 200.8±0.31 µg/g for Mn, and 1185.80±4.66 µg/g to 2488.00±2.37 µg/g for Fe, respectively. The textile industry’s vicinity exhibited the highest Cr concentration among the sampling areas, while Fe concentration surpassed that of other elements significantly. Notably, Cd was undetected in certain soil samples. Metal concentrations followed the order CdASSESSING SOIL PHYSICOCHEMICAL TRAITS AND HEAVY METAL LEVELS NEAR KADUNA METROPOLIS INDUSTRIES.
