Microplastics (MPs) are ubiquitous in the environment, continuously undergo aging processes and release toxic chemical substances. Understanding the environmental behaviors of MPs is critical to accurately evaluate their long-term ecological risk. Generalized two-dimensional correlation spectroscopy (2D-COS) is a powerful tool for MPs studies, which can dig more comprehensive information hiding in the conventional one-dimensional spectra, such as infrared (IR) and Raman spectra. The recent applications of 2D-COS in analyzing the behaviors and fates of MPs in the environment, including their aging processes, and interactions with natural organic matter (NOM) or other chemical substances, were summarized systematically. The main requirements and limitations of current approaches for exploring these processes are discussed, and the corresponding strategies to address these limitations and drawbacks are proposed as well. Finally, new trends of 2D-COS are prospected for analyzing the properties and behaviors of MPs in both natural and artificial environmental processes.
微塑料（MPs）在环境中无处不在，不断经历老化过程并释放有毒化学物质。了解微塑料的环境行为对于准确评估其长期生态风险至关重要。广义二维相关光谱（2D-COS）是微塑料研究的有力工具，它可以挖掘隐藏在传统一维光谱（如红外（IR）光谱和拉曼光谱）中的更全面信息。系统总结了2D-COS最近在分析微塑料在环境中的行为和归宿方面的应用，包括它们的老化过程以及与天然有机物（NOM）或其他化学物质的相互作用。讨论了当前探索这些过程的方法的主要要求和局限性，并提出了克服这些局限性和缺点的相应策略。最后，展望了2D-COS在分析天然和人工环境过程中微塑料的性质和行为方面的新趋势。
