Collection and Characterization of Microplastics Debris in Marine Ecosystems
AI summary Read the abstract
This book chapter describes the key procedures for collecting and characterizing microplastic debris from seawater, sediment, and marine organisms. It covers density separation, sieving, filtration, and spectroscopic identification techniques. The chapter highlights gaps in standardization and discusses emerging extraction approaches for marine microplastic analysis.
This chapter explores the key procedures for sampling, collection, identification, and quantification of the abundance of microplastics (MPs) particles in the marine environment. In marine ecosystems, MP debris exists ubiquitously in seawater, sediments, macrophytes, plankton, shellfish, and fish species. Physically separating the MPs from seawater and sediment samples relies mainly on density separation, sieving, and filtration. Novel extraction techniques for MP are rarely discussed in the literature except for the use of ultrasonication in assisting extraction. Visual identification is the simplest, oldest, and most straightforward strategy of MP analysis. Identification under a light microscope is employed for smaller MPs usually < 1 mm. Scanning electron microscopy is commonly used for the identification of MPs from environmental samples. Infrared (IR) spectroscopy measures transitions between molecular vibrational energy levels in a measured sample by absorption of IR radiation. Quality assurance/quality control has not been well recognized in past MP research.

Analytical Chemistry of Plastic Debris: Sampling, Methods, and Instrumentation
AI summary Read the abstract
This review covers the analytical methods used to collect and characterize plastic debris — from large pieces down to nanoplastics — in environmental samples like water, sediment, and biological tissue. The paper addresses the challenges of sampling across a huge size range and the trade-offs between different detection techniques including spectroscopy and microscopy.

Advanced Techniques for Sampling, Quantification, and Characterization of Microplastics
AI summary Read the abstract
This review chapter covers the full workflow of microplastic analysis — from sampling strategies and extraction methods through identification, quantification, and characterization techniques — and emphasizes the need for standardized protocols across different environmental matrices and biological samples. Without consistent methods, results from different studies cannot be reliably compared, making it harder to understand the true scale of microplastic contamination. Methodological standardization is considered a foundational requirement for advancing the field.
