The recovery of microplastics from rock oysters using digestion method

The widespread deposition of microplastics (<5.0 mm) in the marine environment have appeared to be pervasive across the globe. It has led to major attention of many researchers to study this problem. Despite the amount of work conducted to understand these infamous microplastics, there is still n...
