Evaluation of the microplastics in bivalves and water column at Pantai Teluk Likas, North Borneo, Malaysia
Researchers found microplastics in all three species of shellfish and in the surrounding water at a popular beach in Sabah, Malaysia. One clam species contained over 113 microplastic particles per gram, primarily fibers made of common plastics like nylon and polypropylene. Since these shellfish are eaten by local communities, the contamination raises concerns about human exposure to microplastics through seafood consumption.

Scientists compared microplastic contamination in shellfish from two sites in the Makassar Strait in Indonesia, finding microplastics in all samples tested. The types and amounts of microplastics varied between locations based on local oceanographic conditions and human activity. Since these shellfish are commonly eaten by local populations, the findings raise concerns about microplastic exposure through seafood consumption in the region.
Microplastic ingestion of blood cockles (Tegillarca granosa) in Kuala Juru, Pulau Pinang
Researchers quantified microplastic ingestion in blood cockles (Tegillarca granosa) collected from Kuala Juru, Pulau Pinang, Malaysia, identifying the types and abundances of microplastics present in these commercially harvested bivalves. The study documented microplastic contamination in this economically important shellfish species, raising concerns about human dietary exposure through seafood consumption.
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.
Microplastics Isolated From Shellfish Paratapes undulatus From Kuala Selangor, Selangor, Malaysia
Researchers isolated and characterized microplastics from the soft tissues of the shellfish Paratapes undulatus collected from Kuala Selangor, Malaysia, analyzing 30 samples for plastic type, shape, and size. The study documented the types of microplastics present in this commercially harvested bivalve, raising concern about human exposure through seafood consumption.
Abundance And Distribution Of Plastic Debris In Beach Sediment And Seawater Of The Northern Straits Of Malacca
Researchers surveyed the abundance and distribution of macro-, meso-, and microplastic debris in beach sediments and seawater along the Northern Straits of Malacca in Malaysia, providing baseline contamination data relevant to the country's national roadmap toward reducing single-use plastics.
Microplastics in Malaysia's Aquatic Environment: Current Overview and Future Perspectives
This review summarizes microplastic research across Malaysia's rivers, coastal waters, seafood, and sediments, finding widespread contamination in all aquatic environments studied. Fibers and fragments from everyday plastic products were the most common types found. The authors highlight that Malaysians face significant microplastic exposure through seafood consumption and call for better pollution monitoring and waste management policies.
Microplastic 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.
Beneath the surface: Exploring microplastic intricacies in Anadara granosa
Researchers examined blood cockles from major cultivation areas across Peninsular Malaysia and found microplastics in every sample tested. The most common particles were small fragments and fibers, with the highest contamination on the west coast, raising concerns about human exposure since Malaysia is the world's largest exporter of this popular shellfish.
Marine Macro- And Microplastic Litter Along The Coastal Area Of Kuala Perlis
Researchers surveyed macro- and microplastic litter along the coastal area of Kuala Perlis in northern Malaysia, finding plastic debris at all sampling sites. The study provides baseline contamination data for this understudied coastal region.
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.
Microplastic contamination in green mussel aquaculture at straits of Johor
Microplastic contamination was detected in green mussels cultivated in the Straits of Johor, Malaysia, including both primary microbeads and secondary fragments from larger plastic debris. The study raises concerns about the safety of farmed shellfish for human consumption in this region.
Abundance of microplastics and its ecological risk assessment in coral reef regions of Peninsular Malaysia
Researchers surveyed microplastic contamination in surface waters around coral reef regions of Peninsular Malaysia. They detected microplastics at all sampling sites, with the Perhentian Islands showing significantly higher levels than Tioman Island, likely due to oceanographic differences. Small fragments and fibers of polyethylene and polypropylene were the most common types found, providing baseline data on microplastic pollution in these sensitive reef ecosystems.
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.

Researchers analyzed microplastics in commercially sold bivalves from China, finding contamination across multiple species and geographic origins, with implications for human dietary microplastic exposure through shellfish consumption.
Microplastic accumulation in oysters along a Bornean coastline (Brunei, South China Sea): Insights into local sources and sinks
Researchers found microplastics in all oyster samples along a Bornean coastline, with contamination levels in the polluted Brunei Estuarine System reaching up to 7.20 particles/g tissue, dominated by small polypropylene fragments under 50 µm, while relatively pristine open-shore sites showed substantially lower accumulation.
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.
Characteristics and Distribution of Microplastics in Surface Sediment of Selat Pulau Tuba, Langkawi, Kedah
Researchers characterized the distribution and types of microplastics found in surface sediments of the Selat Pulau Tuba strait in Langkawi, Malaysia.

Microplastics Contamination and Potential Health Risks in the Newly Identified Oyster Crassostrea (Magallana) saidii from Malaysia’s Muar River Estuary
Researchers investigated microplastic contamination in a newly identified oyster species from Malaysia's Muar River estuary and found that microplastic abundance increased with oyster age, from about 3.4 particles in juveniles to 11.6 in adults. Fibers were the most common microplastic type, making up 58% of particles found. Health risk assessments indicated low to moderate hazard levels, and the study suggests this oyster species could serve as a useful bioindicator for monitoring estuarine microplastic pollution.
