In the environment, microplastics vary widely in size
Research gap analysis derived from 4 biology papers in our local library.
The gap
In the environment, microplastics vary widely in size, shape, polymer type, and surface characteristics, and natural populations are typically subjected to chronic rather than acute exposure; these variables may alter ingestion, retention,
