ClearAnalysis of microplastics of a broad size range in commercially important mussels by combining FTIR and Raman spectroscopy approaches
Researchers developed an approach combining FTIR and Raman spectroscopy to analyze microplastics across a broad size range in commercially important mussels. They found that using both techniques together captured a wider spectrum of particle sizes and polymer types than either method alone. The study provides a more complete picture of microplastic contamination in seafood and highlights the importance of using complementary analytical methods for accurate assessment.

Microplastic pollution in wild and aquacultured Mediterranean mussels from the Sea of Marmara: Abundance, characteristics, and health risk estimations
Researchers compared microplastic contamination in wild and commercially farmed mussels from the Sea of Marmara in Turkey. They found microplastics in all mussel samples, with wild mussels containing somewhat different types and amounts compared to aquacultured ones, and fibers being the dominant form in both. The study estimates that regular consumption of these mussels represents a measurable pathway for human exposure to microplastics through seafood.
A review of microplastic pollution in aquaculture: Sources, effects, removal strategies and prospects
This review examines how microplastics contaminate fish farms through environmental inputs and aquaculture equipment, affecting water quality and the health of farmed seafood. Since contaminated aquaculture products are a direct pathway for microplastics to reach the human diet, reducing plastic pollution in fish farming is important for food safety.
Aquaculture in the crossroad of microplastic contamination
Researchers investigated microplastic contamination in three commercially important shellfish species -- oysters, clams, and mussels -- from aquaculture operations in different climate conditions. They found microplastics present in all species and at all sites, with polyester and polyethylene being the most common types. The study raises awareness that aquaculture practices and equipment may contribute to microplastic contamination in farmed seafood.
Detection of Microplastics in Turkish Salmon Purchased from Supermarket
Microplastics were detected in Turkish salmon purchased from supermarkets, with identification performed using stereomicroscopy and Fourier transform infrared spectroscopy. The presence of MPs in commercially sold fish highlighted consumer dietary exposure and the penetration of microplastic pollution into the food supply.
Microplastic pollution: a review of techniques to identify microplastics and their threats to the aquatic ecosystem
This review summarizes existing research on methods for identifying microplastics in water and their effects on aquatic ecosystems. The paper covers detection techniques like infrared and Raman spectroscopy and discusses how microplastics threaten aquatic organisms through ingestion and entanglement. Since these contaminated organisms enter the human food chain, the findings underscore why understanding aquatic microplastic pollution matters for human health.
When it Comes to Microplastic Pollution, is the Aquaculture Industry a Victim or Perpetrator?
This systematic review examines microplastic contamination in aquaculture facilities and the animals raised in them. The findings show widespread microplastic presence in farmed fish and shellfish, meaning that aquaculture products are a significant pathway for human microplastic exposure, which could affect immune function over time.
