ClearMicroplastic contamination in commercially important bivalves from the southwest coast of India
Microplastics were detected in water and three commercially important bivalve species along the southwest coast of India, with concentrations varying by species and collection site. The presence of plastic particles in filter-feeding shellfish intended for human consumption raises concerns about dietary exposure.
Microplastics in commercial bivalves from coastal areas of Thailand and health risk associated with microplastics in ingested bivalves
Researchers measured microplastic contamination in four species of commercial shellfish from Thailand's coastline and assessed the health risk to consumers. Microplastics were found in 69-93% of the shellfish sampled, with fibers being the most common type. Based on local consumption patterns, the study estimated that regular shellfish eaters in Thailand could be ingesting significant amounts of microplastics, though the health risk was deemed low to moderate at current levels.
Towards Risk Assessments of Microplastics in Bivalve Mollusks Globally
Researchers compiled data from 22 countries to assess the risk of microplastic contamination in bivalve mollusks such as mussels and oysters. While most countries showed relatively low pollution levels, the chemical composition of the microplastics found in bivalves varied widely, with some polymers posing greater health concerns than others. The study estimates that regular consumption of contaminated bivalves could represent a meaningful pathway for human microplastic exposure.
Microplastic contamination in Indian edible mussels (Perna perna and Perna viridis) and their environs
Microplastic contamination was found in both Perna viridis and Perna perna mussels and in the surrounding water and sediments at collection sites in India, with larger mussels containing more particles than smaller ones and sediments harboring higher concentrations than overlying water, confirming commercially harvested Indian mussels as vehicles for human microplastic ingestion.
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.

Accumulation of microplastic in edible marine species from North Kerala, India
Researchers found microplastics in the edible tissues of three popular seafood species (clams, shrimp, and anchovies) from fish markets in Kerala, India. Fibers and fragments were the most common shapes, with polyethylene and polypropylene being the dominant plastic types. Since these species are consumed whole or with minimal processing, the study highlights a direct pathway for microplastic ingestion by people who eat locally caught seafood.
Microplastics in four bivalve species and basis for using bivalves as bioindicators of microplastic pollution
Researchers found microplastics in 80% of shellfish samples (scallops, mussels, oysters, and clams) collected across four seasons in Qingdao, China. PVC and rayon fibers were the most common plastic types, with different shellfish species accumulating different sizes and types of particles. Since these shellfish are commonly eaten by people, the findings highlight a direct route for microplastics to enter the human diet through seafood.
Microplastic Pollution in Green Shells in Aquatic Ecosystems: A Literature Review of Determinant Factors and Management
This literature review synthesized 35 studies on microplastic contamination in green mussels (a widely consumed shellfish), finding that fibers under 1 mm were the most common form and that both human and industrial activities drive contamination levels. Because mussels filter large volumes of water, they concentrate microplastics from their surroundings and pass them on to people who eat them, making shellfish a key pathway for human dietary exposure.
The existence of microplastic in Asian green mussels
Microplastics were found in Asian green mussels collected from coastal waters in Southeast Asia, with fiber types dominant, confirming that this widely consumed bivalve accumulates plastic particles. The study raises food safety concerns given the high consumption of this mussel species across the region.
Microplastic contamination in thirty commercially important fish species: Distribution, polymer composition, pollution indices, and human health risks
Researchers examined microplastic contamination in 600 specimens across 30 commercially important fish species from the Indian coast, finding the highest accumulation in the gastrointestinal tract with carnivorous species carrying the greatest burden. Polyethylene and polypropylene fibers were the dominant particle types, and human health risk assessment showed measurable daily intake from consuming these fish, with pollution indices indicating considerable to medium hazard risk levels.
Characterization and risk assessment of microplastics accumulated in sediments and benthic molluscs in the mangrove wetlands along the south-west coast of India
Researchers assessed microplastic contamination in mangrove sediments and four species of benthic molluscs from Vembanad Lake, a major estuary on India's southwest coast. Average sediment contamination levels were relatively high compared to other mangrove regions in India, with polyethylene and polypropylene as the dominant polymers, and ecological risk indices indicated severe microplastic pollution risk for the molluscs studied.
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.
Determination of microplastics in commercial bivalves and estimation of exposure among population in Pasir Penambang, Kuala Selangor
Researchers measured microplastic abundance and characteristics in commercial bivalves from Pasir Penambang, Malaysia, and estimated human dietary exposure, finding that regular consumption of locally sold shellfish poses a notable microplastic ingestion risk.
Hazard index of microplastics contamination in various fishes collected off Parangipettai, Southeast coast of India
Researchers examined microplastic contamination in the gills and guts of 10 fish species collected off the southeast coast of India. All species contained microplastics, predominantly fibers, with low-density polyethylene being the most common polymer type, and the hazard index classified the identified polymers as medium risk for potential health implications through seafood consumption.
Microplastic accumulation in bivalves collected from different coastal areas of Vietnam and an assessment of potential risks
Researchers analyzed microplastic accumulation in five common bivalve species collected from aquaculture areas along the coast of Vietnam, finding microplastics in all samples with an average of about 10.84 items per individual. Fibers were the most common shape, concentrated in gills and digestive glands, and a risk assessment suggested potential implications for human health through seafood consumption.
Microplastic abundance and characteristics in bivalves from Tam Giang-Cau Hai and O Loan Lagoons, coastal regions in Central Vietnam: Implication on human health
Researchers found microplastics in four types of commonly eaten shellfish from coastal lagoons in Central Vietnam, with an average of 0.3 to 0.9 particles per gram of tissue. Fibers were the most common shape, and the estimated weekly human intake from eating these shellfish ranged from about 56 to 486 particles. The study highlights that regular seafood consumption in coastal communities provides a direct route for microplastic exposure in the human diet.
Environmental health risk analysis of microplastics due to consumption of squid and mussels at coastal area
Researchers measured microplastic contamination in mussels and squid from a coastal area in Indonesia and assessed the potential health risks to local communities who consume these seafood products. They found 23 microplastic particles across the samples, primarily fibers made of polyethylene and polypropylene. Statistical modeling showed a significant link between microplastic concentrations in the seafood, intake rates, and health risk indicators for the consuming population.
Risk assessments of microplastic exposure in bivalves living in the coral reefs of Vietnam
Scientists measured microplastic contamination in shellfish living in coral reefs off the coast of Vietnam, finding an average of about 5.6 microplastic particles per individual. Polyethylene and polyamide fragments smaller than 100 micrometers were the most common types found. Since bivalves are filter feeders that people eat whole, these findings mean that consuming shellfish from these reefs involves direct ingestion of microplastics.
Ingestion of microplastics and its potential for causing structural alterations and oxidative stress in Indian green mussel Perna viridis– A multiple biomarker approach
Researchers investigated microplastic contamination in sediment and its effects on Indian green mussels (Perna viridis) near Chennai, India. They found that fibers were the most common microplastic type, and that ingested microplastics caused structural damage to gill tissue, hemocyte infiltration, and oxidative stress in the mussels, indicating significant biological impacts from environmental microplastic exposure.
Microplastics contamination in bivalves from the Daya Bay: Species variability and spatio-temporal distribution and human health risks
Researchers assessed microplastic contamination in six species of bivalves from Daya Bay, China, finding microplastics present in 87 to 93% of individuals sampled. Sediment-dwelling bivalves had higher microplastic levels than water-dwelling species, and the types of microplastics found in the shellfish matched those in the surrounding seawater and sediment. A risk assessment based on polymer hazard levels indicated that microplastic contamination in these bivalves may pose health risks to humans who consume them as seafood.
Exploring microplastics in commercial bivalve species and in bivalve aquaculture waters: Insights from the southern Pacific
Microplastics were detected in multiple commercially sold bivalve species (such as mussels and oysters) and in nearby inland and coastal waters. Because bivalves are widely eaten by humans, the findings raise direct concerns about microplastic dietary exposure through seafood consumption.
Ecological assessment of microplastic contamination in surface water and commercially important edible fishes off Kadalundi estuary, Southwest coast of India
Researchers documented microplastic contamination in both the surface water and 12 commercially important fish species from the Kadalundi estuary in India. Fibers were the most common type of microplastic found, with contamination levels varying across fish species. The findings are significant because this estuary is Kerala's first community reserve, and the contaminated fish are widely consumed by local populations.
Quantification of microplastics using Nile Red in two bivalve species Perna viridis and Meretrix meretrix from three estuaries in Pondicherry, India and microplastic uptake by local communities through bivalve diet
Two bivalve species from three estuaries in Pondicherry, India, contained an average of 0.18 to 1.84 microplastics per gram of tissue, and a community survey estimated that locals who regularly eat bivalves could ingest nearly 4,000 microplastic particles per year from this dietary source alone. The study is the first to quantify microplastic exposure through bivalve consumption for the local population.
