“…Petroleum is a complex mixture, containing significant amount of saturated alkanes, alkynes, alkenes, napthenes, highly toxic polycyclic aromatic hydrocarbons, and some heavy metals [3]. Petroleum compounds are toxic to all forms of life, and have adverse effect on the soil's physical characteristics and biochemical properties [4]. Petroleum hydrocarbon contamination has become a critical environmental issue due to its immobilization and accumulation [5][6]; and is now seriously affecting the safety of ecosystems and human health [4; 7].…”

This study was carried out to investigate the effect of compost manure and organic soap on hydrocarbon degradation in petroleum products contaminated soil. 10 kg of top soil collected at a depth of 0-20 cm, air dried and sieved, were poured into plastic containers. The soil samples were was pounded with 1 L of spent engine oil, 1 L of kerosene, 1 L of petrol and 1 L of diesel daily for five days. The containers were placed under natural environmental conditions for three weeks to enable full acclimatization of the petroleum products with the soil. A completely randomized design comprising T1 (Polluted soil without treatment ‘control’); T2 (10 kg contaminated soil + 500 g organic soap); T3 (10 kg contaminated soil + 500 g compost manure); and T4 (10 kg contaminated soil + 500 g compost manure + 500 g organic soap) was used for this study. Some physical characteristics (soil porosity and specific gravity) and Total Hydrocarbon Content (THC) of the soil samples were tested for, after the full acclimatization of the soil samples, and at the end of the 10 week experimental period, in accordance with standard methods. Results of the study showed that addition of the compost manure and organic soap the contaminated soil samples significantly (p ≤0.05) degraded the THC, and improved the soil physical characteristics. The result showed that the combination of compost manure and organic soap gave the best remediation result (from 957.21 mg/kg to 154.36 mg/kg), followed by organic soap (from 957.21mg/kg to 203.61 mg/kg), and then compost manure (from 957.21 mg/kg to 262.03 mg/kg). At the end of the experimental period, vegetative growth was observed in the treated soil samples; whereas, in the control soil samples vegetative growth was absent. Results obtained from this study have shown that amending petroleum products contaminated soils with compost manure and organic soap will enhance remediation of petroleum products contaminated sites.

“…Okra (Abelmoschus esculentus) are good accumulators of contaminants (Akpan & Usuah, 2014). In addition, studies by Akpokodje and Uguru (2019) reported the degradation of petroleum hydrocarbons from 964.35 to 104 mg kg −1 by okra plants.…”

BackgroundBiochar can enhance phytoremediation in petroleum hydrocarbon polluted soils, making it an intriguing soil amendment option for remediating polluted soil. Biochar can improve the fertility of depleted soils through a range of mechanisms. This study can contribute valuable insights into the origin of biochar and enhance our understanding of the efficacy of different biochar types in remediating petroleum hydrocarbon polluted soils.AimsTo assess the efficacy of different biochar types and plant growth in remediating petroleum hydrocarbon polluted soils.MethodsA field experiment was conducted at the automobile workshop (commonly called mechanic village) from July to October 2021, using a randomized complete block design. The land was sectioned into designated plots with three replicates. Maize stalk biochar (MSB) and nipa palm biochar (NPB) were treated differently in each plot at a rate of 20 t ha−1. Plots containing no biochar were used as controls. Initial and final soil analyses were conducted.ResultsPreliminary soil assessments revealed higher values of soil bulk density (1.51 g cm−3), moisture content (35.02%), organic carbon (41.01 g kg−1), cation exchange capacity (13.27 cmol kg−1), total petroleum hydrocarbon content (PHCt) (775.83 mg kg−1), cadmium (Cd) (5.41 mg kg−1), chromium (Cr) (25 mg kg−1), lead (Pb) (33.51 mg kg−1), and zinc (Zn) (0.91 mg kg−1) in the polluted soil than in the unpolluted counterpart. The polluted soil displayed lower hydraulic conductivity (Ks) (1.17 cm h−1), available phosphorus (69.46 mg kg−1), manganese (Mn) (6.38 mg kg−1) and iron (Fe) (4.18 mg kg−1) contents than the unpolluted soil. The PHCt, Cd, and Cr were significantly decreased following the application of biochar. NPB recorded the lowest petroleum hydrocarbon (19%), lead (37%), manganese (57%), and zinc (69%) contents, whereas MSB had the lowest cadmium (50%) and chromium (27%) contents when compared with the control. Between heavy metal accumulations in the leaves and fruits, a greater accumulation of Cd, Cr, and Pb was found in the leaves, whereas Ni accumulation was found in the fruits. The highest Cd (47.0 mg kg−1) and Ni (8.3 mg kg−1) accumulations in the leaves were recorded in NPB treated plots. Similarly, Cd (5.3 mg kg−1), Cr (3.7 mg kg−1), Pb (21.6 mg kg−1), and Ni (23.4 mg kg−1) accumulation in the fruits recorded the highest values in the NPB treated plots. The NPB plants were the tallest compared with the other treatments. In addition, NPB plants had the widest leaf area compared with other treatments.ConclusionThe results indicated that the amendment of NPB may be suitable for the phytoremediation of soils polluted with petroleum hydrocarbons.

“…Globally, petroleum production is on the increase, despite its widely some of their negative consequences on the ecosystems (Akpomrere and Uguru, 2020a). Petroleum production has three major sections; the exploration and production, the refining and marketing section, and the infrastructure/transportation section (Walls, 2010;Akpokodje et al, 2019a).…”

“…Environmental pollution resulting from oil spills cannot be ignored or disregarded; as one of these environmental impacts is the alterations in the soils' engineering properties and behavior. It has been reported (Elisha, 2012;Al-Obaidy et al, 2019) that oil has the capability of increasing the petroleum hydrocarbons and toxic metals concentrations in the soil; thus causing significant modification to the soils' chemical, mechanical, physical and biological properties (Puri, 2000;Chang et al, 2014;Akpokodje et al, 2019a).…”

Environmental pollution caused by crude oil spills had increased recently in Nigeria, due to increase in crude oil production and the activities of crude oil thieves. This review work was embarked upon to evaluate the impacts of crude oil petroleum products spills on the geotechnical properties of different soils found in Nigeria. The review tried to provide a summary on the influence of crude oil on the Atterberg limits, compaction, permeability, angle of internal friction, cohesion, and consolidation properties of soil samples. Findings from this review revealed that the geotechnical characteristics of soils can be remarkably altered by crude oil and petroleum products impaction. Most of the literatures reviewed indicated a reduction in the Atterberg limits, the compression index (Cc) and the permeability of the soils, as the volume of crude oil in the soils increased. The literature review depicted that the rate, at which the soils’ geotechnical properties were altered, was a factor of the oil volume contained inside the soils and the impacted soil biochemical properties.
