There is a huge risk of contamination of water bodies due to the various oil exploration, transport, and industrial operational activities that are taking place across the world. Physical remediation techniques are considered extremely important for tackling the problems of marine oil spills. This paper provides a unique, specific review on the physical remediation of marine oil spills with special emphasis on types of available physical remediation techniques and their working principles. It also describes the chief latest improvements in the physical remediation techniques that have taken place with time. The paper discusses the various ways by which oil and its derivatives contaminate, and the subsequent effects these contaminants have on the marine ecosystem. The article discusses salient features that make physical remediation an effective marine oil spill counter-measure capable of recovering appreciable amounts of oil while causing minimal or no damage to the marine ecosystem and the workers carrying out the cleanup. Regarding the physical remediation methods, future research may focus on the development of hybrid booms, improved performance of skimmers for different oil types, and further applications involving novel materials like nanoparticles, zeolites for sorbents.
由于世界各地正在进行各种石油勘探、运输和工业作业活动，水体受到严重污染的风险很大。物理修复技术被认为是解决海洋溢油问题的极其重要手段。本文对海洋溢油的物理修复进行了独特、具体的综述，特别强调了可用的物理修复技术的类型及其工作原理。它还描述了随着时间的推移，物理修复技术所发生的主要最新改进。本文讨论了石油及其衍生物污染的各种途径，以及这些污染物对海洋生态系统的后续影响。文章讨论了使物理修复成为一种有效海洋溢油应对措施的显著特点，这种措施能够在对海洋生态系统和清理工作者造成最小或无损害的情况下，回收相当数量的石油。关于物理修复方法，未来的研究可能集中于开发混合围油栏、改进用于不同类型石油的撇油器的性能，以及进一步应用涉及纳米颗粒、沸石等新型材料的吸附剂。
