ClearComparison of theUptake of Tire Particles via Suspensionand Surface Deposit Feeding in the Estuarine Amphipod Corophiumvolutator
Researchers compared tire particle uptake by the estuarine amphipod Corophium volutator through suspension feeding versus surface deposit feeding pathways, finding that exposure route significantly affects ingestion rates, with implications for understanding how aquatic invertebrates accumulate tire-derived microplastic pollution.
Comparison of the Uptake of Tire Particles via Suspension and Surface Deposit Feeding in the Estuarine Amphipod Corophium volutator
Researchers exposed a common estuarine amphipod to tire wear particles at environmentally relevant concentrations and compared how much the animals consumed through two different feeding methods. They found that suspension feeding resulted in significantly higher ingestion of tire particles compared to surface deposit feeding, with particles also adhering to antennae and other body parts. The study helps clarify how bottom-dwelling coastal organisms encounter and take in tire-derived microplastic pollution.
Microplastic Ingestion by a Benthic Amphipod in Different Feeding Modes
This study found that a small estuarine crustacean ingests microplastic beads differently depending on how it feeds — filter-feeding individuals ingested particles proportional to water concentrations, while deposit-feeders preferentially ingested larger particles that settled on the bottom. The findings suggest feeding behavior significantly influences how much and what size microplastics organisms accumulate.
The ecotoxicological effects of tyre particles on mortality and behaviour in the estuarine amphipod, Corophium volutator.
This study assessed the ecotoxicological effects of tyre particles on aquatic organism mortality and behavior, building on recognition that tyre-derived microplastics are among the most significant contributors to aquatic plastic pollution. Results showed tyre particles caused both lethal and sublethal behavioral effects in the tested species.
Feeding type affects microplastic ingestion in a coastal invertebrate community
Researchers exposed a coastal Baltic Sea invertebrate community — including mussels, crustaceans, and deposit feeders — to microplastic beads at three concentrations and found that feeding mode strongly determined ingestion rates, with filter-feeding bivalves accumulating significantly more particles than deposit feeders or free-swimming crustaceans.
The ecotoxicological effects of tyre particles on mortality and behaviour in the estuarine amphipod, Corophium volutator.
Researchers studied the ecotoxicological effects of tyre particles on aquatic organisms, examining mortality and behavioral changes at concentrations relevant to roadway runoff. Tyre particles caused both lethal and sublethal effects, supporting their classification as a significant source of toxic contaminants entering freshwater ecosystems.
Accumulation and depuration of microplastic fibers, fragments, and tire particles in the eastern oyster, Crassostrea virginica: A toxicokinetic approach
This study examined the impacts of microplastic ingestion on the feeding behavior and energy budget of the marine amphipod Gammarus fossarum. Microplastic-exposed amphipods showed reduced food intake and lower assimilation efficiency, leading to decreased energy available for growth.
Habitual feeding patterns impact polystyrene microplastic abundance and potential toxicity in edible benthic mollusks
This study examined how different feeding strategies in edible mollusks affect how many microplastics they accumulate and how toxic the effects are. Researchers found that deposit-feeding snails and filter-feeding clams accumulated microplastics differently, with distinct impacts on digestive enzymes, oxidative stress, and neurotoxicity markers. The findings suggest that a shellfish species' feeding behavior directly influences the microplastic contamination risk for both the animal and human consumers.
Tyre particle exposure affects the health of two key estuarine invertebrates
Researchers found that tyre wear particles in sediment affected the health of two estuarine invertebrates, with clams consuming 25 times more particles than ragworms and showing impacts on feeding, burial rates, and energy reserves at multiple concentrations.
Foraging strategy influences the quantity of ingested micro- and nanoplastics in shorebirds
Researchers found that surface-feeding shorebirds in Tasmania ingested 32 times more micro- and nanoplastics than deeper-foraging species, indicating that foraging strategy rather than local sediment contamination levels determines plastic exposure in coastal birds.
Ingestion and Chronic Effects of Car Tire Tread Particles on Freshwater Benthic Macroinvertebrates
Four freshwater benthic invertebrate species were exposed to car tire tread particles (10–586 μm) for 28 days at concentrations up to 10% sediment dry weight, finding no adverse effects on survival, growth, or feeding rates in any species, while a quantification method confirmed tread particle ingestion in amphipods. The study suggests that tire tread particles at tested concentrations cause minimal harm to freshwater benthic organisms despite being ingested.
Uptake of microplastics by marine worms depends on feeding mode and particle shape but not exposure time
Researchers found that filter-feeding marine worms ingested approximately 15,000% more microfibers than deposit-feeding worms, demonstrating that both feeding mode and particle shape significantly determine microplastic uptake in marine organisms.
Microplastics affect assimilation efficiency in the freshwater amphipod Gammarus fossarum
Researchers examined how two types of microplastics affect the freshwater amphipod Gammarus fossarum. The study found that microplastic exposure reduced assimilation efficiency in these invertebrates, indicating that microplastic ingestion can interfere with nutrient uptake and energy processing in freshwater organisms.
The influence of microplastics pollution on the feeding behavior of a prominent sandy beach amphipod, Orchestoidea tuberculata (Nicolet, 1849)
Microplastic pollution was found to reduce feeding activity and slow growth in a beach amphipod (small crustacean), even at environmentally relevant concentrations. This suggests microplastics can disrupt energy balance and population health in small invertebrates that play important roles in sandy beach ecosystems.
Presence of microplastics in benthic and epibenthic organisms: Influence of habitat, feeding mode and trophic level
This study examined microplastic occurrence in benthic and epibenthic invertebrates from the Western English Channel, finding that habitat type, feeding mode, and trophic level all influenced microplastic ingestion rates. The results suggest that bottom-dwelling filter feeders and deposit feeders are among the most exposed organisms in seafloor food webs.
Microplastic burden in marine benthic invertebrates depends on species traits and feeding ecology within biogeographical provinces
Researchers analyzed microplastic levels in the bodies of marine bottom-dwelling invertebrates across different ocean regions and found that the amount of microplastic ingested depended more on the animals' feeding strategies and body traits than on local pollution levels alone. Filter-feeding and deposit-feeding species accumulated the most particles. The study suggests that simply measuring environmental microplastic concentrations may not accurately predict how much wildlife in an area is actually ingesting.
Microplastics in invertebrates on soft shores in Hong Kong: Influence of habitat, taxa and feeding mode
Researchers surveyed microplastic occurrence in 38 invertebrate species across 18 mudflats and sandy beaches in Hong Kong, finding that feeding mode and habitat type were stronger predictors of microplastic ingestion than taxonomic group, with suspension feeders in mudflat environments showing the highest contamination. The study provides a broad baseline for microplastic uptake across coastal invertebrate communities.
Abundance and characterization of microplastics in amphipods from the Japanese coastal environment
Researchers found high levels of microplastic ingestion in coastal amphipods from Japan, with up to 76 particles per individual and 83% of particles smaller than 90 µm, predominantly polyethylene, raising concerns about microplastic transfer through coastal food webs.
Environmentally relevant concentrations of tyre particles cause toxicity in estuarine invertebrates
Researchers tested the toxicity of tire particles at environmentally relevant concentrations on estuarine species, finding that current environmental levels are sufficient to cause harm. The study identified the most sensitive species and life stages and highlighted tire particles as a priority microplastic source for regulatory attention.
The feeding mode effect: influence on particle ingestion by four invertebrates from Sub-Antarctic and Antarctic waters
Researchers assessed microplastic ingestion in four invertebrate species from sub-Antarctic and Antarctic waters, including crustaceans and gastropods. They found that benthic grazers ingested significantly more but smaller particles compared to scavengers, with cellulose and rayon fibers making up 60% of ingested particles and true microplastics comprising 30%. The findings suggest that feeding mode strongly influences which marine organisms are most susceptible to microplastic ingestion in polar environments.
Feeding behavior is the main driver for microparticle intake in mangrove crabs
Scientists investigated microplastic ingestion by crabs in mangrove ecosystems and found that feeding behavior was the primary driver of particle uptake, with deposit-feeding crabs accumulating more microplastics than filter feeders, underscoring the role of behavioral traits in determining microplastic exposure.
Evaluation of microplastics in marine selective and non-selective suspension-feeding benthic invertebrates
This global meta-analysis of 144 studies found that non-selective suspension-feeding marine invertebrates contain significantly more microplastics than selective feeders, both per individual and per gram of tissue. Polyethylene, PET, and polypropylene were the dominant polymers across 131 species, with feeding strategy emerging as a key factor determining microplastic contamination levels in seafood organisms.
