Description

<p>Microplastic pollution in marine environments is an emerging global issue revealing the importance of microplastic monitoring. Although numerous papers have been published in recent years in relation to microplastics, the methods and techniques for identifying and quantifying them remain underdeveloped, and many researchers are working to develop optimal protocols. Some of the methods currently used include: (1) extraction from seawater, sediment, and organisms; (2) isolation and purification of microplastics from environmental matrices by removing non-plastic materials, both inorganic and organic; and (3) identification of microplastics using a combination of microscopy and chemical analyses. However, these methods are too diverse, often complicated, and they have not been standardized. In this review, we summarize the methods and techniques for sampling, processing, identifying and quantifying microplastics in marine environments and discuss the advantages and limitations of these techniques. We also comment on some future directions for analytical methods of microplastics.</p>
