Microplastics analysis. There is growing research into microplastics, typically submillimeter in size, and which often end up in waterways and oceans. Microfibers are ubiquitous contaminants of emerging concern. Microscopy is a quick and easy way to detect microplastics, however, its effectiveness increases tremendously when combined with infrared or Raman spectroscopy and thus chemical analysis. Characterization of microplastics and nanoplastics requires a scale-bridging combination of microscopies and spectroscopies. The characterization of MPs, which may include isolation, identification and/or quantification, is an analytical challenge due to the lack of harmonization of the existing analytical methods, which hinders any comparison between different studies ( Elert et al., 2017, Rochman et al., 2017, Pico and Barcelo, 2019 ).
