“…Among TPH, long-chain aliphatic hydrocarbons are a group of very recalcitrant compounds that reduce the availability of nutrients in soils, significantly increase water content, and immobilize hydrophobic complexes, thus indirectly affecting the soil’s ecological role ( Devatha et al, 2019 ). Soil pollution also affects food security, both by reducing the agricultural production of the soil (as a consequence of plant metabolism impairing and microbial biomass harming) and by making crops unsafe for consumption ( Kiamarsi et al, 2020 ). Hence, detoxification of TPH-contaminated soils has long been a worldwide challenge and has been addressed in various ways in recent years.…”

The contamination of soil with total petroleum hydrocarbons (TPH) may result in dramatic consequences and needs great attention, as soil rehabilitation would need more effort from a sustainability perspective. However, there is still no known general method since the remediation technology is strictly site-specific. Adaptive biological system dynamics can play a key role in understanding and addressing the potential of situ-specific biological combinations for soil pollutants removal. The potential worst-case of TPH contamination reflects soil affected by heavy industrial activities, such as oil refineries. Therefore, the experimental trial was conducted on a 2,000 m2 area from a contaminated site located in northern Italy. We evaluated the remediation potential over time (270 days) assessing (i) the phytoremediation efficiency of two species of Poaceae (Festuca arundinacea Schreb. and Dactylis glomerata L.) and two species of Fabaceae (Medicago sativa L. and Lotus corniculatus L.) and (ii) the role of the indigenous bacteria flora and endo-mycorrhizae consortium addition in plant growth promotion. We also induced resistance to contamination stress in a field experiment. Thirty-three indigenous bacteria selected from the contaminated soils showed marked plant growth promotion. Moreover, functional metagenomics confirmed the metabolic capability of hydrocarbon-degrading microorganisms living in the polluted soil. Our data showed that soil enzymatic activities increased with hydrocarbon degradation rate after 60 days. Both Poaceae and Fabaceae resulted in remarkable remediation potential. Stress markers and antioxidant activity indicated that the selected plant species generally need some time to adapt to TPH stress. In conclusion, our evaluation implied both the rhizosphere effects and functional features of the plant and suggested that plants should (i) have marked tolerance to specific contaminants, (ii) be characterized by an extensive root system, and (iii) be susceptible to arbuscular mycorrhizal fungi (AMF) infection.

“…Six (6) Rhizobia were isolated from legumes; however, R. leguminosarum BIHIB1217 and R. leguminosarum N871 were the most efficient in breaking down crude oil in soils. A controlled greenhouse experiment revealed that Vetiveria zizanioides could be used in the bioremediation of contaminated soils (Kiamarsi et al 2020 ), with the researchers recommending further research to determine its applicability in the field. Other plants such as Cyperus brevifolius , Mirabilis jalapa L., Tectona grandis , Gmelina arborea , Sebastiania commersoniana , corn ( Zea mays ), and soybean ( Glycine max ) are some of the plants that have been documented to clean up the crude oil-polluted environment (Issoufi et al 2006 ; Agbogidi et al 2007 ; Peng et al 2009 ; Ramos et al 2009 ; Basumatary et al 2012 ).…”

Crude oil exploration in Africa: socio-economic implications, environmental impacts, and mitigation strategies

Crude oil exploration is a source of significant revenue in Africa via trade and investment since its discovery in the mid-19th Century. Crude oil has bolstered the continent’s economy and improved the wellbeing of the citizenry. Historically, Africa has suffered from conflicts due to uneven redistribution of crude oil revenue and severe environmental pollution. Advancements in geophysical survey techniques, such as magnetic and gravity methods, to seismic methods, have made the commercial exploration of crude oil possible for some other countries in Africa apart from Nigeria, Angola, Algeria, Libya, and Egypt. The occurrence of organic-rich, oil-prone Type I, II, and mixed II/III kerogens in sedimentary basins and entrapment within reservoir rocks with intrinsic petrophysical properties are majorly responsible for the large deposits of hydrocarbon in Africa. The unethical practices by some multinational oil corporations have resulted in social movements against them by host communities and human rights groups. The unscrupulous diversion of public funds, award of oil blocks, and production rights to certain individuals have impaired economic growth in Africa. The over-dependence on crude oil revenues has caused the economic recession in oil-producing countries due to plummeting oil prices and global pandemic. Most host communities of crude oil deposits suffer from a lack of infrastructure, arable soils, clean water, and their functioning capabilities are violated by crude oil exploratory activities, without adequate compensations and remedial actions taken by oil companies and the government. Thus, this review examines crude oil exploration in Africa and provides insight into the environmental and socio-economic implications of crude oil exploration in Africa. Furthermore, this report highlights some recommendations that may ensure ethical and sustainable practices toward minimizing negative impacts and improving the quality of life in affected communities.

“…Among the above, which mechanism becomes prevalent in a particular situation would depend on the soil properties, type of plant species used, and the characteristics of the contaminant (Newman and Reynolds 2004). In the case of TPH-contaminated soils, rhizoremediation is widely accepted as an effective mechanism for TPH removal, and it can result in a complete mineralization of pollutants (Correa-García et al 2018;Kamath et al 2004a;Kiamarsi et al 2020;Thijs et al 2016). The highly hydrophobic nature of TPH and its possible sorption limit the ability of microorganisms to access the contaminants.…”

Highlights • Recalcitrant fractions of petroleum hydrocarbon (TPH) cometabolized for remediation • Biostimulation provides propitious environment for degraders in the rhizosphere • Bioaugmentation can supplement the catabolic activities of rhizosphere communities • Effective rhizoremediation requires the modulation of plant-microbial associations • Rhizoremediation of TPH-contaminated sites is a risk-based phytomanagement strategy
