Microplastic pollution in estuarine intertidal crabs
AI summary Read the abstract
This study examined microplastic pollution in estuarine intertidal crabs, focusing on ingestion, physiological impacts, and ecological aspects of microplastic exposure in estuary ecosystems. Results from previous experimental studies showed that ingestion and inhalation of microplastics by estuarine crabs impairs their physiological functions, though ecological-level data remain limited.
The estuary area is receiving and accumulating microplastics (MPs).Many organisms in estuary especially deposit feeders like crabs and clams possibly take MPs into their body.Previous experimental studies showed the ingestion and inhalation of MPs by estuary crabs impaired their physiological functions.However, limited information is available for ecological aspects of MPs in estuaries.Crab's behaviour and

Fate of microplastics among estuarine habitats utilized by intertidal crabs
AI summary Read the abstract
A study of microplastic distribution across different estuarine habitats found that concentrations and types varied substantially depending on whether samples came from sediment surfaces, burrows of intertidal crabs, or surrounding water. Crabs actively redistributed sediment and created habitat structures that accumulated microplastics differently from the surrounding environment. The findings demonstrate that bioturbation by animals plays an important role in determining where microplastics end up in estuarine sediments.
Microplastics uptake and accumulation in the digestive system of the mud crab Rhithropanopeus harrisii
AI summary Read the abstract
Lab experiments with Harris mud crabs showed the crabs readily ingested microplastics, which accumulated in their digestive systems. While plastic exposure did not significantly affect crab growth during the experiment, the findings confirm that crustaceans in brackish estuaries can ingest and retain microplastics.
Ingestion and translocation of microplastics in tissues of deposit-feeding crabs (Grapsoidea, Ocypodoidea) in Kochi estuary, Japan
AI summary Read the abstract
More than half of 116 intertidal crabs collected from a Japanese estuary contained microplastics, with PET fragments dominating and particles concentrated primarily in the gut. Smaller deposit-feeding crab species carried a higher microplastic burden relative to body weight than larger omnivorous species, showing that feeding behavior and body size both shape how much plastic wildlife accumulates in contaminated estuaries.
Ecological traits influence the bioaccumulation of microplastics in commercially important estuarine crabs from the southeastern Gulf of Mexico
AI summary Read the abstract
Researchers found that microplastic accumulation in two commercially important estuarine crab species in the Gulf of Mexico varied significantly based on ecological traits such as feeding behavior and habitat use, with gills and digestive tracts showing higher contamination than muscle tissue.
Microplastic distribution among estuarine sedimentary habitats utilized by intertidal crabs
AI summary Read the abstract
This study mapped microplastic distribution across multiple sedimentary habitat types in an estuary to support spatially refined risk assessments for intertidal fauna. Results showed microplastic abundance varied significantly by habitat, with implications for species that rely on specific substrates.
