Microplastics (MPs) are found in all conceivable media from air, sediments, soils, freshwater, seawater, and organisms, including humans. This paper emphasizes current advances in the study of MPs and presents a review of recent two years of literature on the occurrence and fate of these particles in the environment. The occurrence and fate of MPs are affected by their characteristics and interaction with the media in the environment, including particle mobility and transport processes. The distribution patterns of MPs are affected by their shape, with fibers being transported farther from their sources because they are lighter and smaller. Some results showed that MP distribution is not affected by meteorological parameters or by their density. Soils were shown as important sources of MPs. There are many possible sources of MPs in the environment, and many studies focus on explaining the occurrence and fate of these particles. However, still, MPs transportation is one of the topics that needs more research data.

微塑料 (MP) 存在于空气、沉积物、土壤、淡水、海水和生物体（包括人类）的所有可能的介质中。本文强调了 MPs 研究的当前进展，并回顾了最近两年关于这些粒子在环境中的发生和归宿的文献。MP 的发生和归宿受其特性以及与环境中介质的相互作用（包括粒子迁移率和传输过程）的影响。MP 的分布模式受其形状的影响，由于纤维更轻、更小，因此它们被运输到远离其来源的地方。一些结果表明 MP 分布不受气象参数或其密度的影响。土壤被证明是 MP 的重要来源。环境中有许多可能的 MP 来源，许多研究集中在解释这些粒子的发生和归宿。然而，国会议员的交通仍然是需要更多研究数据的课题之一。
