ClearMolecular Diet Analysis of Asian Clams for Supplementary Biodiversity Monitoring: A Case Study of Nakdong River Estuary
Researchers extracted environmental DNA from the gut contents of Asian clams at three sites in South Korea's Nakdong River Estuary to identify the biodiversity those filter-feeders were exposed to. The technique detected 23 taxa including fish, copepods, and algae, and identified species missed by conventional field surveys.
Using the Asian clam as an indicator of microplastic pollution in freshwater ecosystems
Researchers proposed the Asian clam as a bioindicator species for monitoring microplastic pollution in freshwater ecosystems, building on prior findings of high contamination rates in these organisms. Using a widely distributed filter feeder as a sentinel species could help standardize freshwater microplastic monitoring the way mussels are used in marine settings.
Mangrove mud clam as an effective sentinel species for monitoring changes in coastal microplastic pollution
Researchers collected mangrove mud clams from 18 stations along China's Leizhou Peninsula to evaluate their effectiveness as sentinel organisms for monitoring coastal microplastic pollution. They found that microplastic contamination in the clams correlated with local pollution levels, making them useful biological indicators. The study suggests that this widely distributed species could serve as a standardized tool for tracking changes in coastal microplastic contamination over time.
Asian clam Corbicula fluminea as potential biomonitor of microplastics and metal(oid)s in a Patagonian River
Researchers examined the Asian clam as a potential biological indicator of microplastic pollution in a Patagonian river and found microplastics in the soft tissues of all sampled clams. Fibers were the dominant type detected, suggesting textile-related contamination sources. The study suggests that these widely distributed clams could serve as effective biological monitors for tracking microplastic and metal pollution in freshwater ecosystems.
Assessment of microplastic contamination in clams and shrimp from estuarine environments of Goa: implications for environmental health and food safety
Researchers examined clams and shrimp from estuarine environments in Goa, India, and found microplastics present in both species and their surrounding waters, with shrimp from one site showing particularly high contamination and bioaccumulation. The particles were predominantly polyamide, polyethylene, and polystyrene fibers and fragments, likely originating from fishing, tourism, and waste disposal activities. The findings raise concerns about food safety for local and tourist populations who regularly consume seafood from these coastal areas.
Microplastics uptake in wild Asian green mussels sampled from Pasir Putih estuary in Johor, Malaysia
Researchers detected microplastics in wild Asian green mussels collected from a Malaysian estuary, finding that these filter feeders accumulate plastic particles from the surrounding water and sediments, raising concerns about seafood safety and coastal pollution.
Using eRNA/eDNA metabarcoding to detect community-level impacts of nanoplastic exposure to benthic estuarine ecosystems
Researchers used environmental DNA and RNA metabarcoding to detect community-level impacts of nanoplastic exposure on benthic estuarine organisms in marine sediments. The study suggests that molecular methods offer a powerful approach for assessing how nanoplastic contamination affects the diversity and composition of ecologically important microscopic organisms in marine food webs.
Implication of microplastic presence in sediment and blood clams Anadara granosa (Mollusca: Bivalvia) in the Musi Estuary, Indonesia
Researchers measured microplastic concentrations in sediment and blood clam (Anadara granosa) tissues from coastal collection sites, finding MPs in all samples and identifying specific polymer types consistent with regional fishing gear and packaging waste sources.
The occurrence and exposure of microplastics in bivalves from Qingdao, China
Researchers surveyed microplastic contamination in bivalves such as clams and mussels from the coast of Qingdao, China, and assessed human dietary exposure from eating them. They found an average of about one microplastic particle per individual shellfish, with fibers and rayon being the most common types. The study suggests that regular bivalve consumption in the region contributes to ongoing human microplastic exposure.
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.
Assessment of Microplastics Contamination in Commericial Clams in the Coastal Zone of Vietnam
Microplastic contamination was assessed in commercially harvested clams from aquaculture farms in coastal Vietnam, a country where microplastic impacts on aquaculture are poorly understood. Both vertebrates and invertebrates in coastal areas were found to ingest microplastics, raising concerns about food safety in Vietnamese seafood.
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.
Methodology for microplastics quantification in clams
Researchers developed a simplified methodology for extracting and quantifying microplastics from clam tissue, addressing the need for standardized protocols to assess microplastic accumulation in seafood that poses direct human exposure risk when consumed whole.
Distribution and diversity of microplastics along the aquatic food web in the largest mangrove reserve of China
Researchers surveyed microplastic contamination across the food web in China's largest natural mangrove reserve, examining fish, crabs, shrimp, and bivalves. They found that fish contained the most microplastics, and that organisms feeding indiscriminately accumulated more plastic particles than selective feeders. The study introduces a microplastic diversity index that reveals surprisingly complex contamination patterns across different species and trophic levels in mangrove ecosystems.
Assessing the relationship between the abundance and properties of microplastics in water and in mussels
Researchers investigated the relationship between microplastic levels in coastal waters and in mussels at 25 sites along China's coastline. They found a strong positive correlation, meaning that mussels in more polluted waters contained more microplastics, and that mussels preferentially ingested smaller particles. The study supports the use of mussels as biological indicators for monitoring microplastic contamination in marine environments.
