Beyond Microplastics: Analytical Boundaries, Real-World Barriers, and the Possibilities for Scalable Removal
AI summary Read the abstract
This review critically examines the current state of microplastic identification, characterization, and removal strategies, from laboratory methods to real-world applications. The study highlights significant limitations in both destructive and non-destructive analytical techniques and emphasizes the urgent need for standardized protocols, regulatory frameworks, and interdisciplinary collaboration to address microplastic pollution.
Plastic has transitioned rapidly from a revolutionary material to a global environmental concern, primarily due to mismanagement. Synthetic polymers have quickly gained widespread use due to their versatility, durability, and affordability. However, the properties making plastic indispensable contribute to its permanence in the environment, where it breaks down into microplastics—tiny particles that are typically classified in the size range from 0.1 μm to 5 mm. These particles can now be found in all ecosystems, including the oceans, soil, atmosphere, and within living organisms, raising global concerns about their long-term environmental and health impacts. This review critically examines the current status and potential for identifying, analyzing, and mitigating microplastic pollution. In this paper, we particularly focus on the destructive and non-destructive analytical methods used for microplastic identification and characterization, examining their technical capabilities and limitations, the challenges in maintaining sample integrity, and the reliability of their quantification methods. In addition, the review addresses microplastic removal strategies, from laboratory procedures to real-world applications, examining barriers to implementation and the limited availability of existing solutions. Finally, the review highlights the urgent need for standardized protocols, regulatory frameworks, and interdisciplinary collaboration to address the multifaceted nature of microplastic pollution.

Challenges and Advances in Analytical Techniques to Detect Micro- and Nanoplastics
AI summary Read the abstract
This research review summarizes the current methods scientists use to detect and study microplastics and nanoplastics - tiny plastic particles that can get into our environment, food, and bodies. The authors explain that identifying these extremely small plastic pieces is very challenging and requires advanced laboratory techniques to understand what types of plastics they are and how much is present. Better detection methods are important because we need to understand how much plastic pollution we're exposed to and its potential effects on human health.
