Large spills of refined petroleum products have been an occasional occurrence over the past few decades. This has not been true for large spills of liquefied natural gas (LNG). This paper compares the likely similarities and differences between accidental releases from a ship of sizable quantities of these different hydrocarbon fuels, their subsequent spreading, and possible pool-fire behavior. Quantitative estimates are made of the spread rate and maximum slick size, burn rate, and duration; effective thermal radiation; and subsequent soot generation.

In August 2019, Brazil experienced its largest large oil spill, which impacted extensive areas and significantly affected the northeastern region, particularly Pernambuco. Polycyclic aromatic hydrocarbons (PAHs), major oil components, are critical for assessing fish contamination risks. This study presents two sample pretreatment methods for fish samples - ultrasound-enhanced air-assisted liquid-liquid microextraction (UE-AA-LLME) for low molar mass PAHs, and matrix solid-phase dispersion for high molar mass PAHs - followed by a Gas-Chromatography coupled to Mass Spectrometry (GC-MS) detection.

Environmental exposure to crude oil through seepage and spillage poses risks to the immediate environment and the broader ecosystem as areas along the oil distribution path are affected by the influx of crude petroleum as well as the environmental, economic, and civil unrest that accompanies it. There is a large financial burden associated with the lost resources, including the cost of rehabilitation, and the affected sources of revenue for communities affected by oil spills. As such, it is crucial to determine the responsible parties.

Population expansion, industrialization, urban development, and climate changes increased the water crisis in terms of drinking water availability. Among the various nanomaterials for nanoremediation towards water treatment, FeS-based nanocomposites have emerged as promising candidates in the adsorptive and photocatalytic removal of contaminants. This paper, therefore, evaluates the potential of FeS-based nanocomposites for environmental applications, more specifically the combined use of adsorption and photocatalysis.

The solar-driven catalytic recycling of plastics has recently emerged as a new frontier in industry. Nevertheless, its large-scale application requires the catalysts being capable of the strong absorption of visible and near-infrared light, strengthened photothermal efficiency, high activity and selective toward target product, enhanced stability, as well as easy separation from the products. In this work, magnetic Ni-MnO nanocatalyst (MN/C) is synthesized via the pyrolysis of metal-organic framework (MOF) for the photothermal catalytic recycling of polyethylene terephthalate (PET) to bis(2-hydroxyethyl) terephthalate (BHET).

Reference dosimetry measurement in a pencil beam scanning system can exhibit dose fluctuation due to intra-spill spot positional drift. This results in a noisy reference dosimetry measurement against energy which could introduce errors in monitor unit calibration. The aim of this study is to investigate the impact of smoothing the reference dosimetry measurements on the type A uncertainty.
