ClearComparison of the Uptake of Tire Particles via Suspension and Surface Deposit Feeding in the Estuarine Amphipod Corophium volutator
Researchers exposed the estuarine amphipod Corophium volutator to environmentally relevant concentrations of tire particles and measured ingestion through two feeding modes: suspension and surface deposit feeding. Both feeding modes resulted in tire particle uptake, with deposit feeding leading to higher ingestion, suggesting benthic invertebrates are vulnerable to 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Feeding type and development drive the ingestion of microplastics by freshwater invertebrates
Researchers exposed freshwater invertebrates with different feeding strategies to fluorescent polystyrene microplastics of various sizes and found that all species ingested particles in a concentration-dependent manner. Filter feeders like Daphnia magna consumed the most particles, while feeding type and developmental stage strongly influenced ingestion rates. The study suggests that feeding strategy is a key predictor of microplastic uptake in freshwater food webs, and that younger organisms may be more vulnerable.
Uptake of polystyrene microplastics by marine rotifers under different experimental conditions
Researchers examined polystyrene microplastic uptake by marine rotifers (Brachionus plicatilis), finding ingestion positively correlated with microplastic concentration and peaked at 24 hours before declining, with container type also influencing ingestion rates.
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.
Ingestion and adherence of microplastics by estuarine mysid shrimp
Researchers investigated how estuarine mysid shrimp ingest and accumulate microplastics both internally and on their external body surfaces. The study found microplastics in the shrimp's bodies and fecal pellets, and feeding experiments revealed that these organisms readily consume plastic particles, raising concerns about microplastic transfer through marine food webs.
Direct and trophic exposure of polystyrene and environmental nanoplastics on Corbicula fluminea
Researchers investigated the effects of both direct and trophic exposure routes to polystyrene and environmental nanoplastics on the freshwater bivalve Corbicula fluminea, assessing uptake and biological responses under ecologically relevant conditions.
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.
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.
Is the feeding type related with the content of microplastics in intertidal fish gut?
Researchers compared microplastic ingestion across intertidal fish with different feeding strategies and found that feeding type influenced the amount of plastic found in stomachs. The study suggests that filter feeders and detritivores may ingest more microplastics than active predators, linking ecological role to plastic exposure risk.
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.
