Impacts of microplastics exposure on copepod (Eurytemora affinis) and mussel (Mytilus edulis) gut microbiota
Researchers studied how microplastic exposure affects the copepod Eurytemora affinis and the mussel Mytilus edulis, examining effects on feeding, reproduction, and overall health at relevant environmental concentrations. Results showed microplastics impaired physiological functions in both species, with additional risks from microorganism-colonized plastic surfaces.
Size-dependent effects of microplastics on intestinal microbiome for Perna viridis
Researchers found that the size of microplastic particles determines how they change the gut bacteria of green mussels, with the smallest particles causing the most disruption to beneficial bacteria and promoting potentially harmful species. Since mussels are widely consumed as seafood, changes to their gut health and the bacteria they carry could affect human food safety.
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.

Influence of Microplastics on the Growth and the Intestinal Microbiota Composition of Brine Shrimp
Researchers exposed brine shrimp to polyethylene and polystyrene microplastics and found that both types significantly reduced growth rates, with body length decreasing by 15-18%. The study also revealed that microplastic ingestion altered the gut microbiota composition, increasing microbial diversity and shifting the balance of key bacterial groups in the shrimp intestines.
Effects of nanoplastics on clam Ruditapes philippinarum at environmentally realistic concentrations: Toxicokinetics, toxicity, and gut microbiota
Researchers exposed clams to nanoplastics at concentrations found in real marine environments and tracked how the particles accumulated in their tissues over 14 days. The nanoplastics caused physical damage and significantly altered the clams' gut bacteria. This is concerning because clams are widely consumed seafood, meaning nanoplastic contamination could affect both marine ecosystems and human food sources.
Abundance, composition, and distribution of microplastics in intertidal sediment and soft tissues of four species of Bivalvia from Southeast Brazilian urban beaches
Researchers found 100% microplastic contamination in intertidal sediments and four bivalve species from urbanized Brazilian beaches, identifying polypropylene, polyethylene, and PET polymers in organisms commonly consumed by humans.
Microplastic contamination in commercially important bivalves from the southwest coast of India
Microplastics were detected in water and three commercially important bivalve species along the southwest coast of India, with concentrations varying by species and collection site. The presence of plastic particles in filter-feeding shellfish intended for human consumption raises concerns about dietary exposure.
Microplastic contamination in Bivalves: An assessment of potential health risks to humans and bivalves in the Tam Giang Lagoon
Researchers analysed microplastic contamination in three bivalve species from Tam Giang Lagoon in Vietnam, finding 291 MP particles across 36 specimens, with clams showing the highest burden (67% of total MPs). The findings indicate significant human dietary MP exposure from lagoon bivalves and call for monitoring of this food source.
Presence of microplastics in six bivalve species (Mollusca, Bivalvia) commercially exploited at the Pacific coast of Costa Rica, Central America
Researchers found microplastics in all six commercially exploited bivalve species sampled from the Pacific coast of Costa Rica, with prevalence ranging from 74% to 100% across species, raising concerns about human exposure through seafood consumption in Central American coastal communities.
Environmentally relevant microplastic exposure affects sediment-dwelling bivalves
Researchers exposed two species of sediment-dwelling bivalves to polyethylene microplastics at three concentrations and three size classes for four weeks. The study found species-specific responses including reduced body condition and altered burrowing behavior, suggesting that even at environmentally relevant concentrations, microplastics can affect the physiology and behavior of benthic bivalves.
Assessment of microplastic contamination in Meretrix aurora from Punnakayal Estuary and Tuticorin Coast, Southeast India
Researchers assessed microplastic contamination in the bivalve Meretrix aurora from both a relatively pristine estuary and an urbanized coastal site in southeast India, finding significantly higher microplastic loads at the more urbanized Tuticorin Coast, providing the first contamination data for this commercially important species.
Gut microbiota composition of the isopod Ligia in South Korea exposed to expanded polystyrene pollution
Coastal isopods (Ligia) collected from a plastic-polluted site in South Korea showed measurably different gut microbiome compositions compared to those from a clean site, with lower species richness in polluted areas. This suggests that microplastic contamination can reshape the internal microbial communities of small invertebrates, potentially affecting their health and their role in coastal food webs.
Impacts of microplastics and the associated plastisphere on physiological, biochemical, genetic expression and gut microbiota of the filter-feeder amphioxus
Researchers exposed filter-feeding amphioxus to weathered microplastics colonized by natural marine biofilms and found significant impacts on physiology, biochemistry, and gut microbiota under starvation conditions. The weathered plastics with their attached microbial communities caused more disruption than pristine particles typically used in lab studies. The findings suggest that real-world microplastic pollution, complete with its biofilm coating, may pose greater risks to marine filter feeders than laboratory experiments usually indicate.
Diversity and succession of microbial communities on typical microplastics in Xincun Bay, a long-term mariculture tropical lagoon
Researchers tracked microbial community succession on polyethylene, polystyrene, and polypropylene microplastics over 60 days in a tropical mariculture lagoon, finding that plastisphere bacterial diversity exceeded that of surrounding seawater and that community structure shifted significantly over time.
Effects of microplastics on trophic parameters, abundance and metabolic activities of seawater and fish gut bacteria in mesocosm conditions
Mesocosm experiments showed that microplastics altered bacterial community structure and metabolic activity in both seawater and fish guts, suggesting that plastic pollution can disrupt microbial ecosystems in the marine environment.

Microplastics aggravate the bioaccumulation and corresponding food safety risk of antibiotics in edible bivalves by constraining detoxification-related processes
Researchers found that microplastics increased the accumulation of antibiotics in three commercially important species of edible shellfish. The microplastics interfered with the animals' natural detoxification processes, making it harder for them to clear antibiotic residues from their tissues. The study raises food safety concerns, suggesting that microplastic-contaminated coastal waters could lead to higher antibiotic levels in the seafood people consume.
Potentially pathogenic bacteria in the plastisphere from water, sediments, and commercial fish in a tropical coastal lagoon: An assessment and management proposal
Researchers examined the types of potentially harmful bacteria living on microplastics found in water, sediments, and commercial fish in a tropical coastal lagoon.
