“…This portrayed that the petroleum had negative consequences on the simulated aquatic ecosystem. A similar trend was reported by Ogeleka et al (2017), as a result of oil spills in Niger Delta waters. The TPH concentration of the contaminated water was higher than the maximum approved limit (10 mg/L) by the Nigeria Department of Petroleum Resources (DPR) for water bodies.…”

Environmental degradation resulting from petroleum spills had become a major menace in most petroleum rich regions of the world. The remediation potential of individual green materials and their combinations were quantified in this study. Stimulated petroleum spill water was remediated with water lettuce, activated charcoal, rice husks and their combinations, within an experimental period of 40 days. The total petroleum hydrocarbons (TPH) value of the contaminated water and remediated contaminated water was determined in accordance with American Public Health Association’s (APHA) approved procedures. Findings of this study depicted that the amendments used were able to reduce the TPH concentration of the contaminated water; with activated charcoal tending to have higher remediation efficiency than rice husk. The results revealed that the TPH concentration of the contaminated water treated with only water lettuce, declined from 3897 to 1296 mg/L; while the TPH value of contaminated water treated with water lettuce and activated charcoal (C2 and C3), dropped from 3897 to 535 mg/L and 382.33 mg/L respectively, depending on the charcoal quantity employed. It was also observed that the TPH of the contaminated water treated with water lettuce and rice husk (C4 and C5), dropped from 3897 to 864 mg/L and 680 mg/L respectively, depending on the quantity of rice husks used for the bioremediation program. Additionally, the study’s findings revealed that the TPH of the contaminated water remediated with the combination of water lettuce, charcoal, rice husk and cassava starch (C6 and C7) declined from 3897 to 392 mg/L and 223 mg/L respectively. The study’s findings had depicted that agricultural waste materials can be harnessed to remediate petroleum spill sites, and the remediation efficiency can be optimized through combined remediation methods/materials.

“…For example, Ogeleka et al. (2017) studied the present situation in Warri riverine areas of Ubeji and Jeddo, where an oil spill occurred and remediation was not carried out for over a year. The authors reported that the total petroleum hydrocarbons (TPH) in the sediment was >1000 ppm in Jeddo and > 48 ppm in Ubeji which exceeds the 10 ppm allowable limits set by the DPR, while the total PAHs was 0.012 ppm in Ubeji and 0.026 ppm in Jeddo.…”

Crude oil is the major source of income to the Nigerian economy, which accounts for about 70% of government revenue and more than 83% of the country's total export earnings. Crude oil spills are frequent events in Nigeria and in the past 50 years, it is estimated that 10-13 million tons of oil have been spilled into the environment and more than 77% of it have not been recovered. The spills are caused by sabotage, oil exploration activities, equipment failure, pipeline corrosion, and tanker accidents. In most cases, simple and cheap remediation methods are employed which do not adequately consider the complexity of the different polluted media. This study reviewed the different remediation technologies for polluted water, soil, and sediment media that are appropriate for the local Nigerian environmental conditions. The characteristics of the Nigerian crude oil have been discussed, and the basic factors to be considered in cleaning crude oil contamination were explored. Both full-scale and pilot-scale case studies were reviewed. Biostimulation was identified to have a high potential for cleaning polluted sediments in the Niger Delta, while ex-situ trenching and treatment are recommended for groundwater treatment and bioremediation is recommended for contaminated soils. The limitations of the methods/techniques are discussed, and the future technological prospects are highlighted in this review.

“…The vast area of mangrove swamps and arable land in Nigeria has been devastated due to soil spillage, causing serious environ-mental insecurity (Aniefiok et al, 2018). The environmental hazards associated with oil pollution are dependent on the concentration and volume of oil spilled, the biochemical and physical properties of the soil/water, the presence of natural remediating agent(s), and the prevailing environmental conditions (Ogeleka et al, 2017;Akpomrere and Uguru, 2020a;Akpoghelie et al, 2021).…”

This study was embarked upon to ascertain the effectiveness of using physical and biological remediation procedures to amend the impact of oil pollution on soil engineering properties. Soil contaminated with crude oil at a mix ratio of 20:1 (percentage by weight), was remediated with charcoal (C2), charcoal + seaweed extract + groundnut plant (C3), and charcoal + wood ash + groundnut plant (C4). During the procedure, the soil’s total petroleum hydrocarbon (TPH) level was determined through American Public Health Association (APHA) approved procedures; while the geotechnical (maximum dry density “MDD”, optimal moisture content “OMC, and California bearing ratio “CBR”) and electrical properties (electrical conductivity “EC”, dielectric constant “ɛʹ, and electrical resistivity “ρ”) were measured in accordance with American Society for Testing and Materials (ASTM) and Institute of Electrical and Electronics Engineers (IEEE) approved procedures. The results depicted that the TPH, ɛʹ and ρ-values of the contaminated soil samples declined by 56.71%, 82.01% and 72.80%; 31.65%, 36.85% and 19.92%; and 56.32%, 62.03% and 60.27%, respectively in the C2, C3 and C4 samples after the remediation program; while the soil EC increased by 103.45%, 145.68% and 135.34% in the C2, C3 and C4 samples, respectively. Likewise, the C2, C3 and C4 samples CBR, MDD and OMC values increased by 29.49%, 34.75% and 50.30%; 7.87%, 11.02% and 4.72; and 12.02%, 28.01% and 40.38%, respectively at the end of the experimental period. These findings portrayed that hybridized remediation therapies are better remediating techniques in remediating contaminated soils; hence sustaining the integrity of the soils’ geotechnical and electrical properties.
