Summary: Pollution of the environment by crude oil and oil products poses a global problem. The strain Pseudomonas veronii 7-41 can degrade medium-chain n-alkanes and polycyclic aromatic hydrocarbons. A natural plasmid carrying operons for the degradation of two different classes of hydrocarbons was identified. The strain showed different degradation abilities in single-substrate and double-substrate systems.

Summary: With the ongoing warming of the Arctic Ocean and reduction of sea ice cover, the risk of oil spills and the impact of oil biodegradation in the Arctic are increasing. However, this topic is currently poorly understood. A study conducted in the 1980s revisited two oil spill sites in the Canadian High Arctic and found that residual oil remains present after almost four decades. The presence of residual oil significantly affects microbial communities in sediments, with implications for biodegradation in the short Arctic summers.

Summary: The effects of suspended particles (SP) and dispersants on marine oil snow (MOS) formation were investigated through laboratory experiments. The results showed that a concentration of 0.2 g/L SP was more suitable for MOS formation in crude oil and diesel oil. The addition of dispersants stimulated MOS formation, but the effects differed between crude oil and diesel oil.

Summary: Understanding the immediate impacts of oil spills is crucial for predicting their long-term consequences on the marine environment. This study investigated the early signals of crude oil in seawater and plankton after a major oil spill in the Red Sea. The findings revealed significant incorporation of oil carbon into the dissolved organic carbon pool, alterations in UV absorption, elevated oil fluorescence emissions, changes in the carbon isotope composition of the seawater, enrichment of specific bacterial genera, and the presence of oil pollutants in zooplankton tissues. These early signs highlight the importance of predicting the long-term impacts of marine oil spills.

Summary: This study found that blue mussels exposed to diluted bitumen experienced significant negative effects at the cellular, physiological, and reproductive levels, especially in offspring. Despite lower bioaccumulation of total PAHs, diluted bitumen showed higher toxicity compared to conventional crude oil, causing evident negative transgenerational effects on unexposed F1 generation.

Summary: This study investigates the impact of photooxidation on the environmental fate and effects of spilled oil. Through a simulated experiment, involving the generation of oil slicks and exposure to sunlight for 8 days, the researchers characterized the molecular composition of seawater underneath irradiated and non-irradiated oil slicks. The results show that photooxidation leads to the production of hydrocarbons with oxygen-and sulfur-containing by-products, but the overall ecotoxicity potential remains limited.

Summary: The Arctic presents unique challenges for oil spill research due to extreme conditions. The Baffin Island Oil Spill (BIOS) project revisited sites nearly 40 years later to gather long-term monitoring data. The samples collected showed potentially toxic levels of PAHs, indicating the continued hazard posed by the weathered crude oil residues.

Summary: The COVID-19 pandemic and the oil spill have had significant impacts on Brazil's marine ecology and economy due to government inaction, social inequality, and inadequate research on tropical ecosystems. It is crucial to analyze the short- and long-term effects of the pandemic and oil spill on the recovery of the economy and coastal ecosystems.

Summary: By fabricating ferrimagnetic sponges with hydrophobic porous channels, it is possible to remotely heat heavy crude oil, reducing its viscosity and increasing the flow rate into the pores. When equipped with a self-priming pump, continuous recovery of viscous crude oil can be achieved via remote magnetic heating.

Summary: The study evaluated the effects of ISB residue on Northern shrimp larvae, showing no significant acute or sublethal effects of ISB residue but significant larval mortality in high concentrations of crude oil. This suggests that ISB could mitigate acute impacts of spilled oil on shrimp larvae.

Summary: Negative ion electrospray Orbitrap mass spectrometry was utilized to analyze the impact of conventional crude oil on freshwater samples. Findings revealed that while concentrations of polycyclic aromatic hydrocarbons decreased over time, levels of total organic carbon and oxidized species increased, with O2 and O3 species showing the highest abundance.

Summary: In this study, we investigated the response of indigenous microbial community in Jiaozhou Bay to crude oil and dispersant treatment. The results showed that dispersant treatment was more advantageous for certain microbial species and had stronger effects on the structure and degradation functions of the microbial community compared to crude oil.

Summary: Crude oils are complex mixtures containing toxic compounds. After oil spills, the composition of crude oil changes, affecting its toxicity. This study investigated the changes in composition and toxicity of crude oil through various weathering processes. The results showed that weathering significantly reduced the overall amount of crude oil but increased its toxicity.

Summary: This study found that dispersants and biosurfactants can significantly reduce the interfacial surface tension between water and oil within 24 hours, promoting an increase in the abundance of hydrocarbon-degrading bacteria and the rate of hydrocarbon biodegradation. Some dispersants or biosurfactants can selectively enhance specific bacterial genera, particularly rhamnolipid which shows compatibility with the Pseudomonas genus.

Summary: The study introduces techniques for detecting induction time and develops a modified power-law relation between nucleation rate and supersaturation to show how Reynolds number (Re) can regulate nucleation kinetics. Increasing Re enhances mass and heat transfer processes, therefore increasing permeate flux. The interfacial supersaturation set by the increase in flux modifies the supersaturation rate at induction for crystals formed in the bulk solution, providing evidence that it is the supersaturation level within the boundary layer that controls primary nucleation. The formation of scaling is found to depend more on the interfacial diffusion coefficient and activation energy for nucleation.

Summary: Coagulant dosing can help remove trace organics, such as pharmaceuticals, plasticisers, and flame retardants, in wastewater effluents along with achieving low phosphorus concentrations. However, the behavior of trace organics in coagulation processes is not well understood due to complex interactions between these compounds, coagulants, and dissolved organic matter (DOM). This study evaluated the coagulation removal of twenty-four compounds, including PFAS and brominated flame retardants, using two coagulants (alum, ferric chloride) and five DOM surrogates with different characteristics. The addition of humic acid as a complexing agent can enhance the removal of hydrophobic trace substances, including certain long-chain PFAS and brominated flame retardants.

Summary: The article critically reviews and compares various low-carbon remediation methods and finds that bioremediation and phytoremediation are effective technologies for the remediation of oil-contaminated sites in the Niger Delta region. The proposed framework considers multiple goals, such as effective remediation and limited greenhouse gas emissions, while benefiting local communities socially and economically. Policy and regulatory support, stakeholder capacity building, research and development investment, and collaboration are necessary for sustainable remediation practices and environmental sustainability in the region.
