Water quality, trace gas (SO₂, CO₂, and NO₂), particulate matter (PM 10 as well as PM2.5), and effluent emissions were quantified near cement and oil factories and nearby suburban areas within Delta Nigeria. Results display that ambient air particulate matter PM2.5 varies between 2.1 to 7.9 μg/m³ and VOC (0.013−8.53 μg/m³), while CO and CO₂ were 100% and 30% respectively not within regulatory limits, consequently leading to asthma, coughing, and difficulty breathing. Four out of nine sites investigated for noise effects were above WHO stipulated limits. While some parameters such as BOD and COD display critical levels for effluent scrutiny and conductivity, calcium, TDS, total hardness, DO (Dissolved oxygen) and total alkalinity were also above clean water specifications. Wastewater consists of spills and other water effects which produce pollutants such as soluble organic chemicals that deplete dissolved oxygen, anions, volatile materials, and other heavy metals. Based on age, the greatest impact (52%) was seen in ages varying from 0 to 16 while that of the age set 16 to 60 was 45%. Curbing of oil and cement particulate pollutants and requesting a buffer region between the cement and oil depots and neighborhoods, complemented with regulatory enforcement and persistent monitoring, should be a top precedence to the regulatory authority.

The magnitude of the identified impacts of the ongoing activities of tank farms on climate, air, water, soils, vegetation, waste management, socio-economic and health were rated and the results indicated that the facilities have minimal negative impacts on the recipient environment. Results display that SPM levels in the study range from 69.8–85.4 μg/m³ for PM₁₀, while CO and H₂S were both 100% not within regulatory limits, consequently leading to asthma, coughing and breathing difficulties. Besides, H₂S is corrosive gas, which is rapidly oxidized to sulphur dioxide (SO₂) in the atmosphere, whereas sulphur oxides have been observed to cause a wide variety of health and environmental impacts as they react with other substances in the atmosphere to form acid rain, then affect cardio respiratory system, causing respiratory irritation, broncho-constriction and several cardiovascular abnormalities. Based on age, the greatest impact (53%) was seen in ages varying from 0 to 16 while that of the age set 16 to 60 was 47%. Curb of oil and gas particulate pollutants and requesting a buffer region between the tank farms and neighborhood complemented with regulatory enforcement and persistent monitoring, should be top precedence for the regulatory authority.
