Microplastics (MPs) are considered a new type of pollutant that invades different environmental regions. The gradual increase in consumption of plastic products has led to its abundance in the ecosystem as a result of degradation of larger plastics into smaller particles. A great scientific interest in this topic arose from a series of unknowns that fell into different research disciplines. This review aims to take a look at the latest research papers on the detection of MPs in the world's marine environments. Some of the recent studies performed in the marine environments of the Atlantic, Pacific, Indian, Arctic, and Southern regions are listed in this study. The highest number of MPs were found mainly in the Pacific ocean with an average concentration of 918 items/m³. However, the occurrence of MPs in the Atlantic, Arctic, Indian and Southern oceans reduced to 7.68 item/m³, 0.7 item/m³, 0.32 item/m³ and 0.022 items/m3, respectively. Average MPs concentration reported are based on the case studies listed in this paper. Additionally, this paper highlights the variety of equipment used for the detection of MPs in seawater and deep seawater. On the other hand, the mitigation of MPs occurrence was discussed noting the urgent need for global cooperation to reduce the use of plastics and increase the use of biodegradable and bioplastics. Finally, the importance of this study remains in the broad screening of MPs in the world's marine environment underlying existing research gaps and possible mitigation methods for MPs reduction.

微塑料（MPs）被认为是一种侵入不同环境区域的新型污染物。由于较大的塑料降解成较小的颗粒，塑料制品消费量的逐渐增加导致其在生态系统中大量存在。对这个主题的巨大科学兴趣源于一系列属于不同研究学科的未知数。本综述旨在了解有关在世界海洋环境中检测 MPs 的最新研究论文。本研究列出了最近在大西洋、太平洋、印度、北极和南部地区的海洋环境中进行的一些研究。MPs 数量最多，主要分布在太平洋海域，平均浓度为 918 项/m ³. 然而，大西洋、北极、印度和南大洋中 MPs 的出现减少到 7.68 项/m ³、0.7 项/m ³、0.32 项/m ³和 0.022 件/立方米，分别。报告的平均 MP 浓度基于本文列出的案例研究。此外，本文重点介绍了用于检测海水和深海水中 MPs 的各种设备。另一方面，讨论了减少 MPs 发生的问题，指出迫切需要全球合作以减少塑料的使用并增加可生物降解和生物塑料的使用。最后，这项研究的重要性仍然在于对世界海洋环境中 MPs 的广泛筛选，这是现有研究空白和可能的 MPs 减少缓解方法的基础。
