“…Due to financial limitations, ex situ treatment cannot be used on the vast amount of contaminated land in the Niger Delta region; as a result, cost-effective sustainable remediation technologies, such as solarization and phytoremediation supplemented with biosurfactant, are needed. Phytoremediation is applicable to both organic and inorganic contaminants and is considered a sustainable remediation option with the added advantage of utilizing microorganisms to increase the rate of remediation (Futughe et al, 2020 ; Gabriele et al, 2021 ). The environmental friendliness, biodegradability, reduced toxicity and cost-effectiveness of biosurfactants, make them sustainable compared to their chemically synthesized counterparts (Rahman et al, 2003 ; Das and Mukherjee, 2008 ; Souza et al, 2014 ).…”

Hydrocarbon-contaminated land has been a significant issue throughout Nigeria’s Niger Delta since the discovery of crude oil in 1956. This paper proposes a novel and sustainable technique involving soil solarization, phytoremediation and biosurfactant to treat polycyclic aromatic hydrocarbon (PAH) contamination. The treatment effect on PAH reduction, plant growth, rhizosphere microorganisms and their enzymatic activities was evaluated. Twenty-eight days of solarization was carried out before the introduction of Chromolaena odorata seedlings for an 84-day phytoremediation period using a 4 × 4 (vegetated) and 2 × 4 (non-vegetated) cell microcosms to simulate the Niger Delta’s subtropical conditions. Soil solarization resulted in significant PAH reduction (p ≤ 0.01) of phenanthrene, fluoranthene and benzo(a)pyrene with means reduction of 60.0%, 38.7% and 36.1% compared to their non-solarized counterparts with 18.0%, 18.0% and 18.8% at 95% CI (32.7, 51.3), (15.4, 26.1) and (8.0, 26.6), respectively. In post-solarization, all solarized and vegetated treatment groups significantly reduced (p ≤ 0.01) PAHs compared to their respective counterparts, while biosurfactant contribution in this combination was negligible (p ≥ 0.05). The growth parameters of C. odorata, total soil/rhizosphere heterotrophic microorganisms and their enzymatic activities of dehydrogenase and urease increased in all solarized treatments indicating essential biochemical processes. The novel and successful integration of soil solarization and phytoremediation using indigenous C. odorata as a combined technique to treat even the most recalcitrant form of hydrocarbons (PAHs) brings up new opportunities for a sustainable method of cleaning up contaminated land in Nigeria's oil-rich Niger Delta.

“…They are the most abundant and diverse especially in contaminated site (Chikere & Ekwuabu, 2014). Most of bacterial species reported so far for their PAHs degradation ability are members of Proteobacteria, Actinobacteria, and Firmicutes (Cerniglia, 1993;Peng et al, 2008;Gabriele et al, 2021). Analysis of residual oil extract showed a significant reduction in concentration of various PAH compounds (Table III).…”

“…Although the interaction is plant specific, the rate of PAHs degradation was reported to increase in rhizosphere of different plant species compared to bulk soil as observed by Li et al (2021) using Echinacea purpurea and Festuca sp. The work of Gabriele et al (2021) have shown that removal of pyrene from soil was better achieved by plantbacteria synergism than plant-fungi interaction or phytoextraction. In addition to bacterial degradation, there are speculations that extracellular enzymes secreted by plant in the rhizosphere could play an important role for the degradation of PAHs like pyrene (Agarwal et al, 2020).…”

Petroleum hydrocarbons are among the major driving forces of advancement in the last Century. Some of the hydrocarbons especially polycyclic aromatics are however of health and environmental significance, due to their recalcitrance and persistence leading to adverse effects on health and ecosystem stability. A number of treatment technologies have been used to cleanup hydrocarbon contaminants and the use of phytoremediation technology have recently been described as promising. In this study, phytoremediation of weathered crude oil contaminated soil was carried out in a microcosm using Pennisetumpurpureum for 60 days. Pristine soil samples were collected and mixed with weathered petroleum contaminated soil to achieve 5%, 25%, 35% and 50% w/w contamination levels. Bacterial species in the rhizosphere were isolated and identified and residual oil was extracted and analyzed using GC-MS. Results showed that there was high bacterial population in rhizosphere (5.0×105 cfu/g to 6.4×105 cfu/g) than non-rhizosphere soil (2.4 ×105 cfu/g to 4.0×105 cfu/g); and Bacillus spp. (64.71%) were observed to be predominant in the rhizosphere followed by Micrococcus spp. (17.65%), Pseudomonas aeruginosa (5.88%), Klebsiella pneumoniae (5.88%) and Flavobacterium sp. (5.88%). Hydrocarbon concentration in the rhizosphere was reduced by 82.5%, 60.5%, 58.0% and 48.8% respectively. Complex polycyclic aromatic hydrocarbon compounds detected in the control using GC-MS were significantly reduced or completely degraded. Polycyclic aromatic hydrocarbons such as anthracene, naphthalene, fluorene, benzo (a) anthracene, pyrene and chrysene were significantly reduced at a rate ranging between 13.33% and 97.54%. Based on the rate of PAHs reduction observed in this study, it was evident that P. purpureumsupports cleanup of persistent hydrocarbon contaminants in soil environment. The use of this plant in large scale petroleum hydrocarbon cleanup under field conditions should be investigated.

“…However PYR is not classified as cancerogenic for humans by International Agency Research on Cancer (IARC), literature data showed that as a result of certain processes it could be transformed into cancerogenic compounds (e.g. benzo(a)pyrene) [26][27][28]. Liu et al [29] revealed that the concentration of PAHs in the surface drinking water reached 407 ngL -1 and the four-ring contaminants including PYR were dominant both in water and sediments.…”

Due to the so-called road run-off, many various contaminants including Bisphenol A (BPA) and Pyrene (PYR) could enter the environment and retention basins. It was also suggested in the literature that their removal by using conventional treatment methods could be problematic, and modern techniques should be developed. In this study, the first attempt to remove BPA and PYR by using ultrasonication as a single process and with UV irradiation assistance was performed. The results showed that after 30 min of sonication, the degradation rate of BPA reached 92% while PYR was completely removed, however, after 1 min of the treatment degradation rate of BPA was significantly higher than PYR. In the study effect of pulsed ultrasound was also evaluated and it was found that its effectiveness in micropollutants removal could be higher than ultrasonication in continuous mode. Research revealed that the maximum removal rate of BPA and PYR was obtained during the ultrasonication process combined with UV irradiation-30 min of treatment resulted in 95% of BPA degradation. However, toxicity assessment showed that with an increase in the treatment time, an increase of toxic effects occurs. This phenomenon might be related to degradation of by-products formation which were identified in the study.
