Summary: The study on the effects of exposure to chemical dispersants and crude oil on zebrafish embryos reveals that chemically enhanced water-accommodated fractions (CEWAF) exposure results in more severe developmental delays and higher frequencies of teratogenic effects, indicating that ocular impairment serves as a more sensitive biomarker.

Summary: This study investigated the regulatory role of the GPR120 signaling pathway in LC-PUFA biosynthesis in rabbitfish. The results showed that GPR120 agonists treatment led to lower DHA content and mRNA levels of key genes involved in LC-PUFA biosynthesis. Transcriptome analysis and signaling chemical treatments confirmed the involvement of the ERK1-Srebp1c signaling pathway. These findings reveal a novel regulatory mechanism in vertebrates for LC-PUFA biosynthesis.

Summary: Polycyclic aromatic hydrocarbons from crude oil can negatively impact the health of fish. However, the effects of dysbiosis in fish gut microbial communities and its influence on fish toxic response following exposure have been poorly characterized in marine species. This study used metagenomic and metatranscriptomic sequencing to analyze the microbial communities in juvenile Atlantic cod exposed to dispersed crude oil. The results showed significant changes in microbial composition and function, as well as altered pathways related to energy, biosynthesis, and cellular structure. The study also found common pathways between fish transcriptomic profiling and microbial functional annotations, suggesting the importance of gut microbial communities in fish response to oil exposure.

Summary: The study investigated the properties of an oil spill dispersant composed of Tween 80 and surface-active ionic liquid, as well as its dispersing effectiveness in simulated seawater. A synergistic interaction was observed between the two components, leading to improved dispersal efficiency at specific ratios.

Summary: The health status of Sciaenops ocellatus was studied by exposing the fish to different concentrations of light crude oil and conducting qualitative and quantitative histopathological analysis. The results showed that the exposed fish developed severe histological damage in the liver and kidney, which was strongly associated with crude oil compounds.

Summary: Volatile compounds associated with unpleasant smells in rabbit fish tissues were studied using SPME-GC-MS. The study demonstrated that PUFA oxidation, particularly ARA oxidation initiated by LOX, is responsible for the unpleasant smell in this herbivorous species.

Summary: This study presents a novel solar-heating superhydrophobic sorbent system with carbon dots and commercial porous sponge, which exhibits excellent oil-absorption capacity and rate. Under one-sun irradiation, the system can absorb a large amount of crude oil at a significantly faster rate compared to sorbents fabricated by dip-coating methods.

Summary: The use of dispersants in cold water environments affects microbial communities and their degradation capacities, particularly in the presence of PAHs. The microbial community shows adaptability to the presence of PAHs and dispersants, with specific bacteria taxa potentially involved in PAHs degradation. Dispersants shape microbial community dynamics by stimulating potential dispersant-degrading taxa.

Summary: This article expands the current knowledge of interfacial phenomena related to chemical dispersants application in oil spills, focusing on a representative Brazilian crude oil. By evaluating the dispersion effectiveness of different oil samples under various conditions, including water salinity and dispersant concentration, the study sheds light on the interfacial behavior of this specific oil-water system.

Summary: Studies have shown that oil frozen in sea ice experiences negligible biodegradation before melting, but oil-degrading bacteria surviving in the ice may contribute to biodegradation when the ice melts.

Summary: In this study, the effects of hydrocarbon water-accommodated fraction (WAF) prepared with and without dispersant on benthic microbial communities were investigated. It was found that the contaminated sediment showed less taxa responsive to the addition of both WAF and WAF + dispersant, indicating the presence of hydrocarbon-degrading and dispersant-resistant taxa in the contaminated sediment.
