This study involves the determination of metal concentration in air, water and soil samples at some selected flow stations in Delta State Nigeria. This is to ascertain the level of pollution of the environment by the companies located in the areas. Soil, air and water samples were collected in triplicate for a period of three months. The metals were analyzed by Atomic Absorption Spectrophotometer (AAS) after digestion and extraction. Results of water analysis showed mean copper in the ranged of 0.14±0.03, 0.03±0.02, 0.35±0.00 and 0.23±0.07 mg/L while zinc ranged from 0.06±0.02, 0.11±0.04, 0.29±0.16 and 2.52±0.97 mg/L for PPL, WRPC, AFS and TPS respectively. Cadmium was 0.06±0.01 and 0.05±0.05 mg/L at WRPC and AFS. Mean concentration of lead in soil ranged from 1.09±0.05, 0.95±0.21, 1.69±0.23 and 0.3±0.06 mg/kg; cadmium ranged from 5.26±0.53, 20.45±1.84, 67.48±11.35 and 0.36±0.15 mg/kg; zinc ranged from 38.26±28.50, 116.41±6.71, 682.33±44.82 and 200.44±20.67 mg/kg while copper ranged from 306.17±6.66, 39.64±8.37, 361.60±30.06 and 163.33±9.55 mg/kg for PPL, AFS, WRPC and TPS respectively. Results of air analysis showed of concentrations of lead to ranged from 0.05 – 0.11 µg/kg, cadmium 0.50 – 1.89 µg/kg, zinc 0.05-1.15 µg/kg and copper 0.17 – 0.55 µg/kg. The results of the analysis found the water to be most polluted followed by the soil while the air was the least. The results obtained from the study found some locations polluted while other slightly polluted. The pollution was therefore attributed to the nature of activities carried out at the various locations. It was therefore recommended that humans should consider the consequences for our actions and work to improve air, water and soil quality for future generation
