Microplastic in Sediments and Ingestion Rates in Three Edible Bivalve Mollusc Species in a Southern Philippine Estuary.

ABSTRACT: Plastics are now a major environmental concern worldwide with their widespread contamination and accumulation. Microplastic particle (< 5 mm) is an emerging pollution issue as it is being detected worldwide in aquatic and terrestrial ecosystems, but relatively little is known in tropical regions. This study determined the (1) abundance of microplastics in sediment and (2) in situ and laboratory ingestion rates of microplastics in three scarcely studied tropical bivalve mollusc species (Donax sp., Meretrix meretrix, and Katelysia hiantina) in Panguil Bay, Southern Philippines. A total of 2258 microplastic particles (62.72 ± 18.31 items/m²) were found on the sediment samples. Filament/fiber is the most abundant type of microplastic in terms of morphology, whil
