Fiddler crabs (Tubuca arcuata) as bioindicators of microplastic pollution in mangrove sediments
Researchers used fiddler crabs as bioindicators of microplastic pollution in mangrove sediments, finding that crab tissue microplastic loads correlated with sediment contamination levels and reflected spatial differences in pollution across mangrove sites.
Hemato-biochemical Profiling of a Burrowing Crab Exposed to Polystyrene Microplastic Contaminant
Researchers evaluated the hemato-biochemical effects of polystyrene microplastic exposure on the burrowing crab Cardiosoma guanhumi from Lagos Lagoon mangroves, finding significant reductions in total haemocyte count and altered haemocyte sub-populations compared to unexposed control crabs.
Impact of mangrove restoration on microplastic bioaccumulation in fiddler crabs across degraded, restored, and natural ecosystems
Researchers compared microplastic accumulation in fiddler crabs across degraded, restored, and natural mangrove ecosystems in the Southern Gulf of Mexico. They found that mangrove restoration influenced the amount and types of microplastics that accumulated in the crabs and surrounding sediment. The study suggests that restoring mangrove habitats may help reduce microplastic exposure for the organisms living within them.
Synergistic effects of microplastic and lead trigger physiological and biochemical impairment in a mangrove crab
Researchers exposed mangrove fiddler crabs to microplastics and lead, both alone and in combination, to assess their joint toxic effects. They found that co-exposure synergistically increased lead bioaccumulation, oxygen consumption, and lipid peroxidation while suppressing antioxidant enzyme activity. The study suggests that microplastics can amplify the physiological harm of heavy metal contamination in sensitive mangrove ecosystems.
Characterisation of microplastics in an isolated mangrove island using multiple ecosystem components including brachyuran crabs
Researchers conducted a holistic survey of microplastics across multiple ecosystem components of an isolated mangrove island on the southwest coast of India -- including water, sediment, leaves, stilt roots, fallen leaves, and three brachyuran crab species -- finding MPs in water at 5.42 particles/L, sediment at 400 particles/kg, and in crab gastrointestinal tracts, with fibers dominating all components.
Assessing the presence of microplastics in fiddler crabs (Afruca tangeri) and sediments of the salt marshes of Cadiz Bay (Spain).
This study assessed microplastic presence in fiddler crabs and sediments from coastal environments, where plastic accumulation can disrupt the fauna that depends on these habitats. Microplastics were found in both the crabs and surrounding sediments, indicating contamination throughout the coastal food web.
Dataset of microplastics in the mangrove brachyuran crabs at Setiu Wetlands, Peninsular Malaysia
This dataset documents microplastic contamination found in four species of mangrove crabs with different feeding habits at Setiu Wetlands in Malaysia. The data reveal that microplastics accumulate in these crabs regardless of feeding strategy, indicating widespread contamination in mangrove ecosystems.
Kandungan Mikroplastik pada Rajungan (Portunus pelagicus), Air Laut, dan Sedimen Di Perairan Desa Gugunung Wetan Kabupaten Rembang, Jawa Tengah
This Indonesian study measured microplastic concentrations in blue swimming crabs, seawater, and sediment from coastal waters in Central Java. The detection of microplastics in both the environment and in a commercially important crab species raises food safety concerns for communities that consume these crabs regularly.
Diversity of Bivalvia Types in the Mangrove Area of Sungai Nyirih Village, West Kalimantan
This study identifies and catalogs bivalve species (cockles and blood clams) living in mangrove ecosystems of West Kalimantan, Indonesia. It is not directly about microplastics; while bivalves are commonly used as bioindicators for microplastic contamination, this paper does not assess plastic ingestion or pollution levels and is a false positive for microplastic relevance.
Assessing microplastic contamination levels in ghana's mangrove wetlands
Researchers assessed microplastic contamination levels in mangrove wetlands in Ghana, examining how mangrove tree morphology facilitates plastic accumulation and what concentrations and polymer types are present in these coastal ecosystems. The study addressed threats to mangrove ecological services including water quality improvement, carbon sequestration, and coastline protection posed by plastic pollution.
Assessing microplastic accumulation in the hepatopancreas of marine and freshwater crabs from the North-East Part of the Bay of Bengal
Researchers compared microplastic contamination in the hepatopancreas of three edible crab species from the Bay of Bengal region, including two marine species and one freshwater species. They found that the freshwater crab had the highest microplastic counts, averaging nearly four particles per sample, and identified nine different polymer types across all species. The findings raise concerns about human exposure to microplastics through seafood consumption in the region.
Macroecotoxicological approaches to emerging patterns of microplastic bioaccumulation in crabs from estuarine and marine environments
Smaller, shorter-lived crabs and those from estuarine intertidal/muddy habitats accumulated significantly more microplastics, with burrowing species holding more particles than omnivorous ones. Crabs at lower latitudes -- likely due to mangrove trapping effects -- and non-human-consumed species showed higher microplastic loads, with colorless PA, PP, and PET fibers (1-5 mm) predominating.
Occurrenceand characteristics of microplastics in benthic species from mangrove wetlands of Hainan, South China
Researchers found microplastics in 10 species of benthic organisms — including crabs, bivalves, and snails — across seven mangrove areas in Hainan, China, confirming that mangrove ecosystems and the organisms that inhabit them are significantly contaminated by microplastic pollution.
Microplastic pollution in the surface waters, sediments, and wild crabs of mangrove ecosystems of East Java, Indonesia
Researchers surveyed microplastic contamination across ten mangrove ecosystems in East Java, Indonesia, finding microplastics in surface water, sediment, and wild crabs — with each crab containing an average of 48 plastic particles in its gills and digestive tract, more than 60% of which were fibers. The strong correlation between sediment contamination and microplastics found inside the crabs points to a pathway through which plastics enter the marine food web.
Kandungan Mikroplastik Pada Gastropoda di Kawasan Tahura Ngurah Rai, Bali
This Indonesian study found microplastics in the bodies of gastropods (snails) living in the Tahura Ngurah Rai mangrove in Bali. Gastropods serve as useful bioindicators of microplastic contamination in mangrove ecosystems, which are important coastal habitats and nursery areas for fish.
Plastic in the food chain: Investigating microplastic consumption by the blue-swimming crab (de Rochebrune, 1883) and shrimp (Pérez-Farfante, 1967) from an estuarine system in Ghana
Researchers found microplastics in over 90% of blue-swimming crabs and 31% of shrimp sampled from an estuary in Ghana, with polyethylene being the most common plastic type — raising public health concerns since locals eat these shellfish whole without extensive preparation.
Ecological traits influence the bioaccumulation of microplastics in commercially important estuarine crabs from the southeastern Gulf of Mexico
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.
Metal ion transport: unveiling the difference of nanoplastics and microplastics in Chiromantes dehaani glucolipid metabolism
This study investigates the differences between how nanoplastics and microplastics affect metal ion transport and glucolipid metabolism in the estuarine crab Chiromantes dehaani. Researchers found that microplastic pollution in estuaries can significantly alter how organisms process metals and metabolize fats and sugars. The findings highlight that particle size matters when assessing the biological impacts of plastic pollution on aquatic species important to food security.
Assessing the presence of microplastics in fiddler crabs (Afruca tangeri) and sediments of the salt marshes of Cadiz Bay (Spain).
Researchers assessed microplastic contamination in fiddler crabs and surrounding coastal sediments, finding plastic particles in both organisms and their habitat. The results demonstrate that microplastics are integrated into coastal invertebrate food webs through both direct ingestion and sediment contact.
The Mud Crab Buffet: Microplastics pollution in Scylla Serrata from Kota Mangroves
Researchers recovered 264 microplastic particles from the guts of mud crabs (Scylla serrata) collected from mangroves in Karnataka, India, averaging about 29 particles per crab, with polypropylene, high-density polyethylene, and polyester being the dominant plastics. A hazard index assessment rated the microplastic contamination as a severe risk to the crabs, underscoring the threat to mangrove ecosystems and the seafood that humans consume from them.
Assessment of Heavy Metal Contamination and Pollution Indices in Avicennia marina of Nabq Mangrove Forest, the Red Sea, Egypt
Not relevant to microplastics — this study assesses heavy metal concentrations (including copper, zinc, and lead) in the tissues of mangrove trees in an Egyptian Red Sea nature reserve to evaluate contamination from urbanization and industry.
Effect of salinity on microplastic accumulation and osmoregulatory toxicity in the fiddler crab Minuca rapax
Researchers studied how water salinity affects the accumulation and toxicity of polyethylene microplastics in fiddler crabs from mangrove environments. They found that microplastics accumulated most heavily in the gills, and that salinity levels influenced both how much plastic the crabs absorbed and how it affected their ability to regulate body fluids. The study reveals that environmental salt conditions play an important role in determining how harmful microplastics are to estuarine organisms.
