Heavy metals have great significance due to their tendency to accumulate in the vital human organs over prolonged period of time. Injury to vegetation caused by heavy metals has been well recognised because of the many botanical and chemical investigations during the past century. The high concentration of heavy metals in the soil is reflected by higher concentration of metals in plants and consequently in animal and human bodies. The analysis of heavy metals in some gardening soils was carried out from soil samples at sites W (Wadata), X (Lower Benue), Y(Tionsha) and Z(Wurukum) using Atomic Absorption Spectrophotometer and the results obtained were in the following ranges Cd 0.001±0.0002 - 0.14±0.001mg/kg, Cu 0.01 ±0.05 - 0.15 ±0.0006 mg/kg, Pb 0.15 ±0.01 - 0.23 ±0.005 mg/kg and Ni 0.06 ±0.0009 - 0.10 ±0.009 mg/kg. The highest concentration of as was at Tionsha, while Cd, Cu, Pd and Ni was at Wadata, While the least was at Wurukum, Lower Benue and Tionsha respectively. As was found to be Below Detectable Limit (BDL) at Wadata and Lower Benue, Cu at Tionsha, Pd at Lower Benue and Tionsha and Ni also at Lower Benue and Tionsha. Generally, the result showed that the values were within the set standard for heavy metals in the soil.
