Scanning electron microscopy (SEM) was used to gain qualitative information about the MP size and morphology, being able to resolve the nanometer-scale features and texture of microplastics. All of the MP samples were highly polydisperse, spanning 3 to 4 orders of magnitude, and clear differences in the morphology of the microplastics are apparent. The morphologies can be described as being between two extreme cases of highly tortuous and deformed, or bulky and 'boulder-like'. SEM is an ideal technique for obtaining this type of qualitative information, however it is not suitable for obtaining large population data.
