“…Pollution of the environment by crude oil and oil products is a global problem 1,2 . Once in the soil, these components can be absorbed, concentrated and involved in trophic chains [3][4][5] . Cleaning the environment of petroleum hydrocarbons is not only an important environmental measure, but also contributes to improving the human environment 6,7 .…”

Pollution of the environment by crude oil and oil products (represented by various types of compounds, mainly aliphatic, mono- and polyaromatic hydrocarbons) poses a global problem. The strain Pseudomonas veronii 7–41 can grow on medium-chain n-alkanes (C8–C12) and polycyclic aromatic hydrocarbons such as naphthalene. We performed a genetic analysis and physiological/biochemical characterization of strain 7–41 cultivated in a mineral medium with decane, naphthalene or a mixture of the hydrocarbons. The genes responsible for the degradation of alkanes and PAHs are on the IncP-7 conjugative plasmid and are organized into the alk and nah operons typical of pseudomonads. A natural plasmid carrying functional operons for the degradation of two different classes of hydrocarbons was first described. In monosubstrate systems, 28.4% and 68.8% of decane and naphthalene, respectively, were biodegraded by the late stationary growth phase. In a bisubstrate system, these parameters were 25.4% and 20.8% by the end of the exponential growth phase. Then the biodegradation stopped, and the bacterial culture started dying due to the accumulation of salicylate (naphthalene-degradation metabolite), which is toxic in high concentrations. The activity of the salicylate oxidation enzymes was below the detection limit. These results indicate that the presence of decane and a high concentration of salicylate lead to impairment of hydrocarbon degradation by the strain.

“…It is well documented that hydrocarbons with lower molecular weight are more susceptible to dissolution due to their high solubility and lower hydrophobicity compared to higher molecular weight hydrocarbons (reviewed by Wang et al 2021). In addition, PAHs with logK ow values between 3.7 and 4.8 are more likely to partition into the aqueous phase compared to other higher molecular weight PAHs (Yang et al 2020;Owens et al 2021). The more water soluble PAHs include the NAP, PHEN, DBT and FLU groups, and amongst these groups, the NAP group has the lowest logK ow and highest solubility values.…”

Shoreline oiling poses a risk to coastal ecosystems and resources. Understanding the natural attenuation potential and impact of different sediment types is important for choosing appropriate intervention strategies and priority areas following a spill. Simulated IFO-40 oil spills on artificial beach mesocosms were carried out using different sediment types: sandy beach and sandy tidal flat, under low energy tidal cycles over a 5-day period. Chemical and biological analysis of leachate and sediment was conducted to understand the movement of oil through these mesocosms. Rapid oil movement from the oil slick to the surface sediment layer was observed in the sandy beach enclosures, while slower oil movement was observed in the sandy tidal flat enclosures. Increased hydrocarbon dissolution was observed in the sandy beach enclosures, marked by higher concentrations of low molecular weight n-Alkanes (C12 − 15) and naphthalenes (C0 − 3) in sandy beach leachate compared to sandy tidal flat samples. Despite the increase in hydrocarbons, there were no major shifts in microbial communities observed in the leachate and sediment compartments for either sediment type. Both prokaryote and microeukaryote communities differed between the two sediment types, with little overlap between dominant sequences. Our results indicate that limited oil penetration occurs within sandy tidal flat shorelines resulting in oil accumulation suggesting that sorbent or vacuuming could be used as emergency response to minimize the environmental and ecological impacts of spilled oil.

“…The corresponding treatment measures are also difficult, and artificial in situ soil remediation is not only expensive, but also may bring secondary pollution [1] .Natural attenuation refers to the process of reducing the concentration and total amount of pollutants in soil or groundwater, and the toxicity and mobility of pollutants under the involvement of multiple effects (e.g., dilution, volatilization, biochemical effects, etc.) [2] ,which has been widely used to assess the feasibility of treatment and remediation programs and the cost-effectiveness of remediation programs, as a technology relying on the full capacity of natural purification [3] .For this reason a large number of studies have focused on assessing the natural attenuation capacity and exploring the main factors influencing the rate of natural attenuation. In the past, there is a scarcity of studies on the natural attenuation process of petroleum contaminants in soils, and the mechanisms by which the natural degradation process of petroleum contaminants in soil systems is affected by the intrinsic characteristics of the site are not well defined.…”

Oil spills in soil can form source areas of contamination that are ecologically hazardous in the long term. The natural process by which the concentration, toxicity and mobility of petroleum contaminants in soil decrease under the combined effects of biochemistry and other aspects without human interference is called natural attenuation. This paper provides a systematic review of the natural attenuation characteristics of petroleum contaminants in soil and its research tools, focusing on the typical biogeochemical and hydrogeological characteristics of the site, and describes the influence of both on the natural attenuation process of contaminants in soil and its mechanism. It also clarifies the influence of petroleum properties, sediment types, organic matter changes, photo-oxidation reactions and microorganisms on the natural attenuation of the source area, and summarises the relevant indicators that can characterise the natural attenuation of petroleum contamination in the source area; at the same time, it outlines the various types of prediction methods of natural attenuation processes, and points out the focus and difficulties of the multidisciplinary fusion of the research directions and the multi-data drive, and finally puts forward a proposal for the study of natural attenuation of petroleum in soils. Finally, the research on the natural attenuation of soil oil pollution source area is proposed. Overall, due to the complexity of organic matter, mineral and microbial components, and the inhomogeneity of hydrogeological conditions, the study of the influence of the intrinsic properties of the site on the natural attenuation of pollutants needs to be further strengthened, and this paper focuses on the identification of the spatial and temporal dynamics of the natural attenuation of pollutants, and the deepening of the understanding of the interaction mechanisms between typical biogeochemical and hydrogeological conditions of the site and the pollutants.
