“…The use of the microbial remediation technique along with the introduction of biosurfactants and/or biochar appears to be an effective remediation strategy (Gaur et al, 2021). The WDPT tests performed on different biochars have shown that their addition to soil contaminated with crude oil may be a reasonable approach to reducing soil hydrophobicity (Ebrahimzadeh Omran et al, 2020).…”

This paper shows the changes in water sorptivity (S w ) and hydrophobicity following soil contamination with petroleum hydrocarbons (PHs) under different soil moistures.Laboratory experiments were carried out to verify that contamination with PHs reduces S w , thus affecting the infiltrability, which in practice influences the field water capacity and the availability of water for plants. Soil water repellency (SWR) was estimated by the repellency index (R) and water drop penetration time (WDPT).The increase in PHs contamination contributed to SWR and caused a significant decrease in S w . With the decrease in moisture, the water sorptivity of the soil increased, reaching its maximum at 0.12-0.15 cm 3 cm À3 , which was the threshold value in the case of the analysed soil, and then decreased drastically. The R index and the WDPT revealed a similar trend, inversely related to the level of soil contamination with PHs. The increase in SWR and the accompanying decrease in S w made the soil less resistant to drought. The total amount of water available to plants in the control soil was 19.04%, whereas contamination with PHs equal to 100 g kg À1 caused a decrease to 6.36%. The almost threefold decrease in the total amount of water has a fundamental influence on increasing the risk of soil drought. The results obtained indicated that the interrelationship presented between the level of contamination with PHs, water sorptivity, SWR and soil moisture are the keys to predicting the environmental effects of contamination with PHs. The obtained results indicate that the undertaken remediation measures aimed at restoring the hydrological function of the soil system should be preceded by an assessment of soil hydrophobicity.

“…The rapid growth in industrial, agricultural, and municipal activities, together with the unprecedented global population growth rate, has led to a high demand for petroleum production (Singha and Pandey, 2021). Global demand for petroleum products is expected to reach 100.90 million barrels per day (Gaur et al, 2021). Petroleum industrial activities, such as drilling, exploration, storage, transportation, processing, and refining, are major sources of petroleum hydrocarbon spillage, which leads to terrestrial oil pollution that generally contains hydrophobic compounds (Chettri et al, 2021).…”

“…This, in turn, adversely affects seed germination and alters the physicochemical, biochemical, and indigenous microbial diversity properties of the soil (Nassar and Said, 2021). Soil particles coated with hydrophobic films of highmolecular-weight PHC components lose their ability to absorb and retain moisture, which leads to a considerable loss of water conductivity and capacity (Gaur et al, 2021). As a result, the upper contaminated layers dry out, and the cleaner lower layers suffer from excessive moisture, leading to correct air and water conditions and anaerobic processes.…”

Petroleum hydrocarbons (PHCs) are key energy sources for several industries and daily life. Soil contamination from oily PHC spills is commonly detected in cities and industrial facilities where crude oil is used. The release of PHC pollutants into the environment, whether accidentally from petroleum industries or human activities, has become a leading source of soil pollution. Consequently, the mineralization of PHC-polluted sites has become a central issue worldwide. Although bioremediation is imperative for environmental safety and management, several approaches have been developed for PHC bioremediation. However, much remains to be explored in this regard. This review explores bioremediation of PHC-contaminated soil and provides a comprehensive examination of the principles, degradation mechanisms, and recent advancements in the field. Several microbial species have been used to study the bioremediation of PHCs, emphasizing the pivotal roles of diverse microbial communities. Aspergillus spp., Proteobacteria, and Firmicutes groups of microorganisms were the most efficient in remediating PHC-contaminated soil. The fundamental concepts behind the bioremediation of PHC and the complex mechanisms that govern degradation were elucidated. Limiting factors in the bioremediation process and recent innovations propelling the field were also discussed. Therefore, understanding the degradation pathway, ensuring complete degradation of contaminants, and flexible legislation for the proper use of genetically engineered microbes can make bioremediation more sustainable and cost-effective.

“…It is well known that oil refinery effluents contain polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds, phenols (C 6 H 6 O), and heavy metals that can cause genotoxic effects in living organisms [2][3][4]. Therefore, it is necessary to integrate different physicochemical and biological technologies to mitigate their effects on the environment, complying with the water quality parameters established in environmental regulations [5].…”

In the present work, treatability studies were carried out with oil refinery wastewater (effluent from the secondary treatment) using electrooxidation (EO) process employing two mixed oxide anodes: SnO2‐RuO2‐IrO2|Ti and IrO2‐Ta2O5|Ti. Both electrodes’ performance were compared by their capacity to generate active chlorine in a synthetic solution and organic matter mineralization of a sample with an average phenol concentration of 100 mg L‐1. Prior to degradation experiments, surface analysis, and linear sweep voltammetry tests were performed. SnO2‐RuO2‐IrO2|Ti anode yielded higher active chlorine, reaching an average concentration of 340 mg L‐1 at 90 min of electrolysis and 25 mA cm‐2. On the other hand, IrO2‐Ta2O5|Ti anode only generated an average concentration of 200 mg L‐1 at 90 min and 40 mA cm‐2. Regarding the degradation experiments, SnO2‐RuO2‐IrO2|Ti anode showed the highest dissolved organic carbon (DOC) removal, ranging from 26% to 40%. In addition, through a three‐dimensional excitation‐emission matrix (3DEEM) fluorescence analysis, it was possible to elucidate the degradation of phenol and some possible polycyclic aromatic hydrocarbons present in the effluent. The results suggested that 65‐90% of the hydrocarbons and phenol present in the effluent were degraded with the SnO2‐RuO2‐IrO2|Ti anode applying 25 mA cm‐2 within the first 30 min of electrolysis, reaching almost 99% degradation at 90 min. The EO process using SnO2‐RuO2‐IrO2|Ti can be an alternative for tertiary treatment of oil refinery wastewater for degradation and mineralization of the remaining organic matter of secondary effluents (biological processes) via active chlorine species.This article is protected by copyright.
