Methods of the Investigation and Chemical Analysis of Microplastics and the Determination of Associated Compounds
Summary
This review surveys the major analytical methods used to identify microplastics and determine their chemical composition, including spectral, chromatographic, microscopic, and thermal techniques. Researchers compare the strengths and limitations of each approach for detecting different polymer types and associated chemical additives. The study serves as a practical guide for selecting appropriate methods for microplastic analysis in environmental and biological samples.
Microplastic emissions to the environment increase every year. Over the past twenty years after the first publication on the study of microplastics, the problem of the global environmental pollution by synthetic materials has been confirmed, its toxicological effect has been proven at all levels of the organization of biosystems, including human health. Spectral, chromatographic, microscopic, and thermal methods of analysis are used to study microplastics. This review considers these groups of methods in the context of their application to the identification of microplastics and the determination of toxic substances associated with them.
