Plastic pollution and marine mussels: Unravelling disparities in research efforts, biological effects and influences of global warming
This review analyzed 106 studies on how plastic pollution, including microplastics, nanoplastics, and chemicals that leach from plastics, affects marine mussels. The research found effects at every biological level, from molecular and cellular damage to changes in behavior and reproduction. Since mussels are filter feeders that concentrate pollutants and are widely eaten by humans, they serve as both early warning indicators of plastic pollution and a direct pathway for human exposure.
An overview of the internalization and effects of microplastics and nanoplastics as pollutants of emerging concern in bivalves
This review examines how bivalves such as mussels and oysters take up, retain, and are affected by microplastics and nanoplastics. Researchers summarized findings on particle characteristics that influence toxicity, including size, shape, density, and the ability to carry other pollutants. The study highlights that while significant progress has been made using bivalves as bioindicators of plastic pollution, major knowledge gaps remain in understanding the full scope of these impacts.
Microplastic pollution in commercially important edible marine bivalves: A comprehensive review
This review summarizes research on microplastic contamination in edible shellfish like mussels, clams, and oysters, which accumulate high levels of plastic particles in their tissues. Because bivalves are eaten whole including their digestive systems, they are a direct pathway for microplastics to enter the human body. While microplastics do not appear to kill shellfish outright, they can harm their immune systems and reproduction, potentially affecting both shellfish populations and human consumers.
Direct and indirect effects of microplastics on bivalves, with a focus on edible species: A mini-review
This mini-review examined direct and indirect pathways by which microplastics affect bivalves including mussels, oysters, and clams, finding evidence that microplastics impair physiology, alter immune responses, and act as vectors for chemical pollutants. The authors highlight microplastics as an emerging threat to bivalve populations and seafood safety.
Bivalves as Biological Sieves: Bioreactivity Pathways of Microplastics and Nanoplastics
This review examines how filter-feeding bivalves like mussels and oysters process and accumulate microplastics and nanoplastics of different sizes. Researchers found that larger particles pass through relatively quickly in feces, while smaller microplastics and nanoplastics tend to accumulate in digestive tissues and immune cells with longer retention times, making bivalves valuable bioindicators of plastic pollution.
Exposure of Mytilus galloprovincialis to Microplastics: Accumulation, Depuration and Evaluation of the Expression Levels of a Selection of Molecular Biomarkers
Researchers exposed Mediterranean mussels to a realistic mixture of microplastic types and then tested whether a standard purification process could remove them. They found that purification significantly reduced microplastic contamination in the mussels and that molecular biomarkers in the gills could detect the biological effects of exposure. The study suggests that both purification protocols and molecular monitoring tools could help address microplastic risks in farmed shellfish.
