ClearImpact of nanoparticles on human health and disease
This review assessed whether marine snails (gastropods) can serve as reliable indicator species for microplastic pollution in the ocean, examining global literature across five gastropod subclasses. On average, about 33 plastic pieces were found per individual gastropod, with bottom-dwelling species accumulating the most. The findings suggest that gastropods are useful bioindicators for monitoring microplastic contamination in marine environments from the seafloor to the surface.
Impact of micro- and nano-plastics on marine organisms under environmentally relevant conditions
This review summarized the impacts of micro- and nanoplastics on marine organisms including microalgae, crustaceans, snails, and fish at environmentally realistic concentrations. Researchers found that while some species showed tolerance at low concentrations, chronic exposure to nanoplastics in particular caused oxidative stress and behavioral changes. The study emphasizes that more research using real-world concentration levels is needed to accurately assess the risks microplastics pose to ocean life.

This literature review examined microplastic contamination in gastropod species across marine environments, assessing ingestion rates, particle types, and potential consequences for organism health and human seafood safety. The review found that gastropods consistently harbor microplastics, particularly fibers, and that bottom-dwelling species are among the most exposed due to sediment contact.
Unraveling the ecotoxicological effects of micro and nano-plastics on aquatic organisms and human health
This review summarizes the growing body of evidence on how micro- and nanoplastics affect aquatic organisms and, through the food chain, potentially human health. The tiny plastic particles absorb toxic pollutants and pathogens from the water, acting as carriers that deliver these harmful substances into the bodies of fish, shellfish, and other organisms. The review highlights that both direct plastic toxicity and indirect chemical exposure through contaminated seafood pose risks to human consumers.
