Soil samples from abattoirs in five major cities in Delta State, Nigeria, were analyzed to assess the effect of abattoir activities on the surrounding environment. The pH values ranged from 5.60 to 8.30 with mean value of 7.17±0.78 indicating that the soils were slightly acidic to slightly alkaline while the mean value for control sites was 5.66±1.21 indicating moderate acidity. Total organic carbon and total nitrogen had the mean values of 2.51±1.57 and 0.137±0.075 respectively showing presence of biodegradable and compostable materials. Cation exchange capacity had the mean value of 9.42±2.84 CmolKg-1 suggesting the soil moderate nutrient retention capacity. The heavy metals had the mean values of (mgKg-1) 17.87±5.96 for Fe, 3.65±2.92 for Cu, 0.08±0.02 for Cr, 0.20±0.19 for Pb and 2.87±1.49 for Mn. These values were significantly higher than those obtained for the control sites. The pollution level assessment of the heavy metals showed that the activities of abattoirs have moderate pollutional impact on the surrounding environment.
