“…A large number of oils spilled into the marine environment naturally (e.g., natural seeps) or accidentally (e.g., from platform blowouts and tank or pipeline leaks) highlighted the importance of effective spill response technologies (Bi et al 2021, Vahabisani et al 2021. A warming climate opens the waterways in the Arctic region and highlights the potential oil spill incidents in the marine environment, caused by increasing Arctic oil storage, exploration, production, and shipping activities.…”

The increasing oil demand and busy waterways highlight the importance of oil spill preparedness and responses. Dispersants attract attention as an effective response tool to manage the impacts of major spill incidents. Despite in-depth laboratory evaluations on the effectiveness of chemical dispersants and their impacts on the transportation and fate of spilled oils, how dispersant works at sea remains a question and calls for the tests with greater realism to validate laboratory results, bring in energy impacts, and evaluate dispersant application equipment. Mesoscale studies and field trials have thus been widely conducted to assist better spill response operations. Such research attempts, however, lack a systematic summary. This study tried to fill the knowledge gaps by introducing the mesoscale facilities developed to advance the understanding of dispersant effectiveness on various sea conditions. An up-to-date overview of mesoscale studies and field trial assessments of dispersant effectiveness has also been conducted. We ended this review by highlighting the importance of public perception and future research needs to promote the approval and application of dispersants in spill incidents.

“…They can be sprayed by aircraft and boats to reduce the droplets' size to boost the oil's thinning and dispersion to lessen the toxicity level (White & Karras, 2021;Feng et al, 2021). The surface washing agents with the flushing technique can be applied together to remove spilled oil effectively (Feng et al, 2021;Bi et al, 2021).…”

Guyana is an oil-producing country vulnerable to potential oil spills and the environmental risks posed by oil and gas exploration and production activities. Despite the technologically advanced equipment employed by Exxon-Mobil Guyana and affiliates, an oil spill could occur due to accidents, equipment failures, or sabotages. The selected coastal communities as the study areas in Region 1 and Region 2 could be adversely affected, particularly the mangrove ecosystems. Potential oil spill pollution will adversely impact mangrove ecosystems in Region 1 and Region 2. Mangroves offer significant benefits to coastal communities, such as coastal defence and carbon sequestration, which puts Guyana on the world map. The research aimed to investigate the mitigation strategies to manage the potential environmental risks on mangrove ecosystems in the coastal communities of Region 1 and Region 2. It followed a qualitative approach and conducted semi-structured interviews with the Toshaos of the selected coastal communities. The data analysis strategy was thematic analysis using the Nvivo software. The major themes included legal and policy frameworks, oil spill response strategies, community-based involvement, and monitoring and enforcement of regulations. The significant results included reviewing and updating the regulatory framework for mangrove How to cite this paper: Henry, C. A., Singh, T. B., & Oyedotun, T. D. T.

“…Research about piezocatalyst development has been in no small part steeped in two-dimensional sheets of molybdenum disulfide (MoS 2 ). − MoS 2 attracts great interest owing to its strong ferroelectricity, easy deformation, and its ability to tolerate remarkable pressure. − For instance, Li et al demonstrated that MoS 2 nanosheets demonstrated the highest amplitude of piezoresponse compared to WS 2 and WSe 2 . Significantly, MoS 2 has displayed good biocompatibility and low toxicity, which facilitate its application in the biomedical area. − In evaluating a suitable washing option, toxicity may often outweigh effectiveness in terms of importance . In this study, single- and few-layer MoS 2 was used as a piezoelectric surface-washing fluid to clean up the oiled sand.…”

The gigantic petroleum exploration and production are threatening the lives and well-being of people and other species. Pizeocatalysis is a bridge to transfer ceaseless mechanical energy to chemical energy and thus triggers redox reactions. In this study, piezoelectric MoS2 was used as a surface-washing fluid to physically and chemically decontaminate oiled sands. The MoS2 displayed single- and few-layer structures, which were conducive to piezocatalysis. The addition of MoS2 could decrease the interfacial tension, thereby facilitating oil removal. The oil removal efficiency varied under different environmental conditions. Quenching experiments with different scavengers and electron paramagnetic resonance (EPR) spectra showed the existence of reactive oxygen species (ROS) including 1O2, •O2 –, and •OH. It was found that shaking was a necessary initiator to trigger piezocatalysis and singlet oxygen (1O2) was the dominant ROS. The MoS2 fluid exhibited good stability, maintaining high removal efficiency after five reuse cycles. Notably, results indicated that high-molecular-weight hydrocarbons were degraded into lower-molecular-weight ones, indicating the existence of chemical oxidation pathways in oil removal. This study provides a facile self-powered piezocatalytic surface-washing process by harnessing natural energy from water agitation to clean up oiled sands.
