“…Others, like cadmium and lead, have no known beneficial function and pose health risks even at low levels of exposure and uptake. The amount of exposure or uptake is obviously a key factor in assessing adverse health impacts, and defines the field of toxicology (Yerima et al 2019). However, the metal speciation is also a critical factor in determining toxicity.…”

The discharge of crude oil products to the environment (soil, water and air) has great negative impacts on the organisms living therein. Most of these effects are from heavy metals, total petroleum hydrocarbons (TPH), polyaromatic hydrocarbons (PAH) among others. This research adopts an extensive review of literatures such as conference papers, journal articles, internet sources, books to find out the amount of total metal concentrations and the total petroleum hydrocarbons (TPH) that are likely to be found on crude oil contaminated soil even after remediation or cleanup activities have been carried out. The driving force behind this research is the fact that the people living in most petroleum-contaminated areas such as the Niger Delta Region of Nigeria still experience some negative effects (such as health and agricultural effects) associated with the crude oil pollutants even after remediation. The study concludes that even though heavy metals were still present in the remediated soil, they are not bioavailable for plants uptake; hence their presence is negligible harmless. On the other hand, the total petroleum hydrocarbons (TPH) that remains after cleanup is still well above the background level. As such, it would impose negative impacts on the inhabitants of such areas. The study further recommends that more effective methods of remediation should be carried out, or a combination of more than one method should be adopted in other to obtain absolute cleanup of the polluted area..

Metal works process is one of the most important anthropogenic sources of heavy metal emissions into environment, consequently posing a risk to human health through inhalations, ingestion and dermal contact. This study assessed the total levels of Al, Si, Zn, Fe, Pb and Cd in soils around metal works, their potential risk to the environment and health. The study provides baseline of the determine analytes in the under review as well as the potential risk associated with them. Soil quality parameters reveals the soil pH 8.78±0.30 as strongly alkaline (8.50 – 9.00), organic matter content (2.15±0.42%) and effective cation exchange capacity (ECEC) (18.56 cmol/kg) been moderate. The heavy metals and metalloid levels were in the order: Fe (20647 mg/kg) > Al (3940.90 mg/kg) > Zn (373.03 mg/kg) > Pb (120.2 mg/kg) > Si (45.54 mg/kg) > Cd (6.37 mg/kg) respectively where the geo-accumulation indices of Zn (1.73), Pb (2.52) and Cd (5.27) showed moderate contamination with respect to zinc; moderate to strong contamination wit.h respect to lead and strong to extreme contamination with respect to cadmium. Similarly, contamination factor of Zn (4.97) reveals considerable contamination with zinc likewise the contamination factors of Pb (8.58) and Cd (57.9) implied very high contamination by Pb and Cd. Cancer Risk (CR) of Pb and Cd in adults were all greater than the value found for children in all respect either via ingestion, inhalation or dermal route of exposures. The CRderm of both Cd and Pb exceeded the carcinogenic risk limit of 1.0×10-4 hence indicates a lifetime cancer risk to both children and adults. Hence, the soil is recommended for cleanup in order to guaranty sound health and ecological sustainability with respect to the contaminants.
