Researchers developed a method for extracting nanoplastics from oyster and fish tissues using enzymatic digestion, sequential membrane filtration, and purification steps, addressing a critical methodological gap for assessing nanoplastic contamination in seafood.
Extraction 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.
Detection, counting and characterization of nanoplastics in marine bioindicators: a proof of principle study
Researchers demonstrated a proof-of-concept workflow for detecting and counting nanoplastic particles (below 1 µm) in marine invertebrate tissues using electron microscopy and spectroscopic confirmation, finding nanoplastics in marine bioindicator species and establishing a methodology for future monitoring programs.
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.
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.

Nano-plastics and their analytical characterisation and fate in the marine environment: From source to sea
Researchers reviewed the sources, environmental fate, organism interactions, and analytical detection methods for nano-sized plastic polymers in the marine environment, concluding that nanoplastics pose the greatest ecological risk among plastic size fractions and that standardized analytical protocols for nanoplastic characterization are urgently needed.
The invisible pollutant in water: Nanoplastics in seafood
This review examines the emerging presence of nanoplastics in seawater and seafood, discussing how wild-caught seafood is particularly vulnerable to contamination and outlining the analytical challenges of detecting nanoscale particles in food matrices.
Dietary exposure to microplastic via shellfish and the importance of the edible shellfish tissue measurements
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.
Micro and Nanoplastics size distribution in mussel tissues: first evidence, identification, and quantification in the nanogram range
Italian researchers used a highly sensitive mass spectrometry technique to detect and quantify both microplastics and nanoplastics in farmed mussels, finding plastic particles in every sample tested. Nanoplastics in the 20–200 nm range were present in substantial quantities, and the authors estimate that European seafood consumers could ingest over 2 milligrams of nanoplastics per year through mussel consumption alone. This is one of the first studies to directly quantify nanoplastics in a commonly eaten seafood, raising significant concerns about dietary exposure.
Are microplastics impacting shellfish?
Researchers investigated whether microplastic contamination measurably impacts shellfish physiology, growth, reproduction, and health outcomes, assessing the ecological and food safety implications of microplastic exposure in commercially and ecologically important bivalve species.
