Microplastic contamination in no-take Marine Protected Areas of Brazil: Bivalves as sentinels.

Microplastics (MPs) are pervasive environmental contaminants even in remote and pristine locations. Despite extensive literature documenting their widespread presence in marine environments, there is limited understanding of MP contamination in Marine Protected Areas (MPAs), particularly in developing countries. This study assessed MP contamination using multiple filter-feeding bivalve species as sentinels.
