“…It is important to mentioned that these metals may be present in the oil itself or in the materials and products employed in the extraction, transportation, and processing of the oil (Wang, Liu, & Zhang, 2013a). The potential for exposure to these metals through soil, water, or air contamination may depend on the specific circumstances of the oil-polluted site and the activities occurring at the study site (Okonofua et al, 2023). For example, if the oil-polluted site is located near a residential area, the potential for exposure to these metals through air contamination may be higher than if the study location is located in a more remote area.…”

Crude oil pollution in the Niger Delta, perpetrated by both local communities and industrial actors, has brought about soil pollution with its consequent ecological, human health and food challenges. The purpose of this research was to examine the concentration and distribution of heavy metals in soil from communities contaminated by crude oil in Niger Delta, and to evaluate the potential health risks to residents from exposure to these contaminants. To achieve this, soil samples were collected from the Ihwrekreka community and analyzed for heavy metal content using inductively coupled plasma mass spectrometry (ICP-MS). The analytical results in mg/kg revealed a significant metals pollution level derived from the oil spill in the soil ranging from 4.85 -17,078 (Cu), 1.01 -16.1 (Cd), 0.22 -36.8 (Cr), 8.28 -40.9 (Ni), 7.51 -6474 (Pb), and 8.84 -12,851 (Zn) respectively. Most of the metals were above the permissible limits of World Health Organization, with Cu, Zn, and Pb as the most contaminating metals. Lead was found to be the main contributor to the hazard index (HI) values for both children and adults in the study area, with its concentration exceeding the permitted limits set by the WHO and the EC. The hazard index (HI) values of Pb, Cu, Zn, Cd, Ni, and Cr were significantly higher than 1. These findings suggest that the release of heavy metals from an oil-contaminated site may pose a risk to human health and the environment.

“…In many affected sites, the population and natural resources are exposed to continuous risks (Okonofua et al, 2023;Ukhurebor et al, 2021). Agricultural soils contaminated by hydrocarbons show problems in quality and cultivation production, which are due to the loss of beneficial microflora, as well as to the decrease of air and water availability and contaminant toxicity among other factors (Devi et al, 2022).…”

Objective: The purpose of the present study is to highlight the importance of assessing bioremediation and total petroleum hydrocarbon removal by bioaugmentation and biostimulation on the rhizosphere. Design/methodology/approach: An 89-day experiment was established with treatments considering plant (corn) establishment–crude petroleum (25,000 mg kg-1)–bacteria and hydrocarbonoclastic fungi–adding nitrogen and phosphorus to agricultural soil. At the end of the experiment, hydrocarbonoclastic fungal and bacterial populations and total petroleum hydrocarbon removal were assessed. Results: Both microbial groups increased in number and time. The treatment with 120 kg nitrogen ha-1 and 12.5 kg phosphorus ha-1 allowed the highest population (227 x 103 g-1 of colony forming units (CFU) of hydrocarbonoclastic bacteria). A total of 83% petroleum hydrocarbon removal was obtained as established in 89 days. Limitations on study/implications: The effectiveness of bioremediation can vary significantly in real environments due to factors, such as soil variability, climate. Findings/conclusions: The previous results highlight the importance of using these bioremediation techniques to eliminate hydrocarbons in contaminated agricultural soils.
