Abstract
Human activity is a notable component of environmental pollution. Soil samples were collected from soils in three different workshops within the Rumuolumeni/Akpor axis of Obio/Akpor Local Government area of Rivers State. The soil samples were treated to laboratory conditions and finally digested using a combination of acids. The final productof the digestion was analyzed for heavy metals using atomic absorption spectrophotometer (AAS) to determine their concentrations. The results of the heavy metals showed a variation of 842.30±10.68-1324.69±31.26 mg/kg for iron (Fe), 9.33±2.10-13.70±4.53 mg/kg for lead (Pb), 10.70±2.64-16.35±3.81 mg/Kg for copper (Cu), 0.74±0.00-1.43±0.02 mg/kg for cadmium (Cd), 9.11±1.96-19.20±5.38 mg/kg for chromium (Cr), 2.69±1.01-4.65±1.13 mg/kg for nickel (Ni) and 1.31±0.07-2.42±0.21 mg/kg for arsenic (As). The result further revealed that the most abundant metal in the workshop soils was Fe > Cr > Cu > Pb > Ni > As > Cd. Contamination factor evaluation showed that all the metals in the stations were at the level of contamination except Fe in all the stations which was uncontaminated in all stations and Cd with Ni that are at level of pollution with Cd and Ni at the some of the stations and As in all the stations. Enrichment factor evaluation of the soils from the stations revealed that the soils were enriched by all the metals through human influence. The ecological risk assessment of the heavy metals in the soils showed their levels are at low ecological risk to the environment except the values of Cd obtained at Elioparanwo and Chinwota stations.
