A Quantitative Analysis of Microplastic Ingestion in Northern New York Bivalves
AI summary Read the abstract
Researchers quantified microplastic ingestion in bivalves collected from northern New York waterways, measuring particle counts and types across multiple species. Bivalves are filter feeders that bioaccumulate microplastics directly from their environment, making them both sentinels of freshwater contamination and a dietary exposure route for humans who consume shellfish.
Plastics play a vital role in modern society, but their widespread use has led ...

Microplastics in Freshwater Mussels from Northern New York and the Adirondack Park
AI summary Read the abstract
Researchers quantified microplastic contamination in freshwater mussels collected from northern New York and the Adirondack Park, a region considered relatively pristine, and found plastic particles present across sampling sites. The detection of microplastics in filter-feeding mussels from protected wilderness areas demonstrates that contamination is pervasive beyond industrial zones and enters the food chain even in remote ecosystems.
Microplastics Uptake and Egestion Dynamics in Pacific Oysters, Magallana Gigas (Thunberg, 1793), Under Controlled Conditions
AI summary Read the abstract
Researchers studied how Pacific oysters (Magallana gigas) ingest and egest microplastics under controlled conditions, finding that ingestion rates were rapid and dose-dependent while egestion was slower, resulting in temporary accumulation that increases the oysters' exposure to adsorbed pollutants and pathogens during the retention period.
Gastropods as Suitable Models for the Assessment of Microplastic Pollution: Advances, Challenges, and Current Progress
AI summary Read the abstract
Researchers assess gastropod molluscs as biological models for monitoring microplastic pollution, reviewing the ecotoxicological effects of microplastics on both aquatic and terrestrial gastropod species and discussing their strengths and limitations as environmental sentinels.
