ClearExtraction and identification of microplastics from mussels: Method development and preliminary results
Scientists developed and validated a method for extracting and identifying microplastics from mussel tissue, then applied it to measure contamination in commercially harvested mussels. The method produced reliable, reproducible results, providing a practical tool for monitoring microplastic levels in one of the world's most widely consumed shellfish.

Microplastics extraction from oyster tissue v1
Researchers developed and validated a protocol for extracting microplastics from oyster tissue, addressing the challenges of isolating plastic particles from a complex biological matrix that includes lipids, proteins, and mineral content. The method enables reliable quantification of microplastic contamination in bivalves — a widely consumed seafood and established bioindicator of coastal pollution — supporting standardised monitoring of microplastic uptake in marine food species.
Selection and optimization of a protocol for extraction of microplastics from Mactra veneriformis
Researchers tested and optimized a protocol for extracting microplastics from the commercial clam Mactra veneriformis, finding 10% potassium hydroxide (KOH) was the best tissue-digesting agent while preserving plastic particles. The validated method was then applied to assess real-world microplastic contamination in commercially sold clams.

Assessment of Microplastics Contamination in Commericial Clams in the Coastal Zone of Vietnam
Microplastic contamination was assessed in commercially harvested clams from aquaculture farms in coastal Vietnam, a country where microplastic impacts on aquaculture are poorly understood. Both vertebrates and invertebrates in coastal areas were found to ingest microplastics, raising concerns about food safety in Vietnamese seafood.
Microplastic Contamination from Ready-to-Cook Clams: Implications for Food Safety and Human Exposure
Researchers characterized microplastic contamination in ready-to-cook frozen clams from commercial sources, assessing particle morphology, chemical identity, and polymer hazard index, and estimated average daily intake for consumers to evaluate food safety implications of microplastic contamination in bivalve seafood.

This study highlighted shellfish as a major source of human dietary exposure to micro- and nanoplastics, emphasizing the need for standardized analytical methods to enable comparable exposure assessments and risk characterizations across different countries and shellfish species.
Development and optimization of a standard method for extraction of microplastics in mussels by enzyme digestion of soft tissues
Researchers optimized methods for digesting mussel soft tissue and extracting microplastics for analysis, finding that sodium hydroxide and enzymatic digestion both achieved high recoveries (~93%) while acid digestion damaged certain plastic types. The validated method provides a reliable protocol for monitoring microplastic contamination in commercially important bivalves.

Optimisation of Small Microplastic Extraction and Quantification from Marine Tissues
Scientists developed a better way to find and count tiny plastic particles (called microplastics) inside sea creatures like mussels.

The improved method will help scientists better track plastic pollution in our food chain and understand potential health risks.

Microplastic contamination in edible clams from popular recreational clam-digging sites in Hong Kong and implications for human health
Researchers examined 249 wild clams from recreational digging sites in Hong Kong and found that over 56% contained microplastics, averaging about one particle per individual. Based on consumption patterns, they estimated that Hong Kong residents may ingest over 14,000 microplastic particles annually from wild clam consumption alone. A risk assessment using a polymer hazard index indicated a medium level of concern for human health.
