Summary: This study examined the potential impacts of the offshore oil industry on cold-water marine species in Atlantic Canada, specifically focusing on the sublethal developmental impacts of oil exposure and spill response measures on Atlantic cod. The results showed that increasing oil concentrations led to an increased incidence of sublethal symptoms in cod, such as impaired swimming ability and spinal curvature. The study also found intraspecific variation in the response among cod families, suggesting that sensitivity to oil exposure depends on genetic background.

Summary: Dispersants can make the separation of oil-water emulsions challenging by reducing oil-water interfacial tension. However, at specific concentrations, dispersants can disperse a portion of the crude oil into small droplets. Complete rejection of oil in separation tests was accompanied by a flux decline due to a decrease in membrane oleophobicity.

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: This study analyzed the nuclear magnetic resonance (NMR) blood serum metabolic profiles of 106 head and neck squamous cell carcinoma (HNSCC) patients during radio- and concurrent radio-chemotherapy, finding that seven metabolites were significantly altered by radiotherapy. The influence of irradiated volume on metabolic profile was weak, mainly correlating with inflammatory markers, creatinine, lymphocyte count, and branched-chain amino acids.

Summary: In this study, the metabolic effects of Cyadox were evaluated using comprehensive methods. The results showed dose-dependent alterations in the metabolism of urine, kidney, plasma, and liver. Gene expressions in the liver were also affected by high dose Cyadox treatment, with differentially expressed genes involved in xenobiotic metabolism, lipid metabolism, energy metabolism, nucleic acid metabolism, inflammatory response, and oxidative stress.

Summary: This study investigates the influence of different organic ligands on the catalytic activity of copper-based organic salts. It is found that copper stearate and copper decanoate exhibit higher catalytic activity, with copper decanoate having the lowest activation energy during the oxidation process.

Summary: The study shows that the addition of chemical dispersants exacerbates the effects of toxic compounds in oil, increasing the bioavailability of PAHs in zebrafish and causing diverse alterations at different levels of biological organization. The importance of combining multilevel endpoints for reliable risk assessment is emphasized, and the results of dispersant impact on oil toxicity can support decision making for oil spill response strategies.

Summary: This study utilized statistical multi-way analysis and machine learning methods combined with diffusion-ordered NMR spectroscopy to explore the potential of predicting crude oil stability. By applying MWA and ML techniques, a robust model was developed to accurately predict crude oil stability and other important parameters, demonstrating great potential for practical applications in the petroleum industry.

Summary: The fish external microbiota competitively excludes pathogens and prevents proliferation of opportunistic organisms. Prolonged exposure to dispersed oil leads to dysbiosis in fish external microbiota, reducing the host's immune response to pathogens.

Summary: This paper analyses the radiance reflectance modelling of a sea area polluted with an oil emulsion at different depths, and determines 555 nm as the optimal wavelength for oil emulsion detection based on the simulations. The study discusses the contrast parameter in relation to various thicknesses of polluted water layers, noting changes in contrast for layers closer to the sea surface.

Summary: While much is known about the genes and pathways responsible for petroleum biodegradation in marine environments, less is understood about the biodegradation of the chemical dispersant Corexit 9500. This study investigated the genes and pathways involved in the biodegradation of oil and Corexit 9500 in Arctic seawater through metatranscriptomic sequencing. The results revealed a suite of fatty acid degradation genes that were enriched by both oil and Corexit exposure, suggesting a potential pathway for Corexit surfactant biodegradation. The study also identified specific microbial taxa associated with the degradation of oil and Corexit. Overall, this research provides new insights into the biodegradation of Corexit 9500 in the Arctic marine environment.

Summary: This paper introduces three NMR methods for quantifying wax crystallization in crude oil systems, based on free induction decay and Carr-Purcell-Meiboom-Gill pulse sequences. These methods allow for the quantification of non-crystalline wax content and calculation of crystalline wax component in systems with high wax content. Through comparisons with DSC method and model systems, these methods are proved to be reliable.
