Abstract:
This project assessed the heavy metals and total petroleum hydrocarbon content of soil from farm near petrol filling station in Effurun, Delta State. This research was conducted to determine the concentration of heavy metals (Lead, Cadmium, Manganese, Nickel) and total petroleum hydrocarbon as well as pollution levels. Approximately 300g of composite soil samples was collected at a depth 0cm - 20cm based on proximity to the grid points. Findings revealed that farms around petrol filling stations where moderately polluted with manganese and petroleum hydrocarbon posing effects of soil degradation and potential harm to groundwater, affecting ecosystems and human health. Also, farms were unpolluted with chromium and nickel. While these values may not immediately pose significant threats based on common environmental standards, the accumulation of heavy metals and petroleum hydrocarbons in soil can have long-term implications, especially as it regards Lead. Continuous exposure to even low levels of heavy metals and TPH can degrade soil quality, disrupt plant growth, and pose a risk to groundwater through leaching. In conclusion, heavy metals and Total Petroleum Hydrocarbon (TPH) levels of soil near petrol filling stations are moderately polluted. Statistical analysis showed that concentration levels are similar across all farms.
