Assessing microplastic pollution and its interaction with organic pollutants in green mussels (Perna viridis) from Quang Ninh coastal waters, Viet Nam
AI summary Read the abstract
Scientists studying green mussels off the coast of Vietnam found that these shellfish soak up tiny plastic particles (microplastics) and chemical pollutants from seawater at much higher levels than what's in the surrounding water or seabed—meaning mussels can concentrate pollution from their environment. Interestingly, the amount of microplastics in the mussels didn't clearly line up with levels of certain harmful chemicals (like flame retardants and plasticizers) also found in their tissue, suggesting these pollutants may build up somewhat independently. Since many people eat mussels and similar shellfish, this research is a remin
Microplastics (MPs) are known as emerging pollutants not only for their ability to adsorb contaminants in the surrounding environment but also because of the additives present in their composition. Assessing the correlation of microplastics with other pollutants can be considered a basis for making deeper judgments about the potential risks of microplastics and the ecosystem. In this study, we collected samples at ten locations in the coastal area of Quang Ninh. Empirical evidence demonstrates a universally pronounced biological concentration index for mussels relative to seawater, irrespective of the spatial distribution of the sampling points (Bioconcentration Ratio > 1). Biota sediment accumulation factor > 1, on average more than 10 times. The pollution load index (PLI) index in mussels ranges from 5.23 to 11.65 at the dangerous level I to II, the PLI index in sediment ranges from 3.32 to 7.03 at level I, and the PLI index in seawater samples rangesfrom 32.66 to 54.16 at level IV. Within the evaluated green mussels, MP accumulation in the soft tissue exhibited marginal to negligible statistical relationships with the targeted contaminants: Polybrominated Diphenyl Ethers (r = 0.37), Bisphenol A (r = 0.14), and Phthalic acid esters (r = - 0.22). Given these preliminary findings, further research is strictly required to definitively ascertain whether the overall quantity of MPs corresponds with the tissue concentrations of Bisphenol A, Phthalic acid esters, and Polybrominated Diphenyl Ethers. These differences suggest that tissue and side effects influence the interactions between these contaminants.

Evaluation of microplastic bioaccumulation capacity of mussel (Perna viridis) and surrounding environment in the North coast of Vietnam
AI summary Read the abstract
Researchers measured microplastic contamination in green mussels, seawater, and beach sediment along the northern coast of Vietnam. Mussels contained an average of about 25 microplastic pieces per individual, while beach sediments had concentrations around 4,800 pieces per kilogram. PET was the most common polymer type, and the study shows that Vietnamese coastal waters and seafood carry meaningful levels of microplastic contamination.
Contamination of microplastic in bivalve: first evaluation in Vietnam

For the first time in Vietnam, microplastics were detected inside green mussels (Perna viridis), with fibers and fragments being the most common types. Given that mussels are widely eaten in Vietnam, this raises concerns about microplastic exposure through seafood.
Qualitative Assessment and Management of Microplastics in Asian Green Mussels (Perna viridis) Cultured in Bacoor Bay,Cavite, Phillipines
AI summary Read the abstract
Green mussels cultured in Bacoor Bay in the Philippines were found to contain microplastics, which can accumulate persistent organic pollutants in the tissues of filter-feeding shellfish. Since green mussels are widely consumed as food, the findings raise food safety concerns about the combined exposure to microplastics and associated chemical contaminants.

AI summary Read the abstract
Researchers tested green mussels from four coastal areas in Quang Ninh province, Vietnam, finding microplastics in 91.7% of samples, mostly tiny fragments under 150 micrometers. The most common plastic type found was PET, making up 67.9% of all particles detected.
Microplastics Contamination in the Kalirejo Coastal Area, East Java, Indonesia and their Presence in Green Mussels (Perna viridis)
AI summary Read the abstract
Researchers surveyed the waters and green mussels along the Kalirejo coast in East Java, Indonesia, and found microplastics in all samples, with higher concentrations at shallower depths. Polyethylene fragments were the most common type, and there was a strong correlation between microplastic levels in the water and in mussel tissues, indicating the animals absorb plastics directly from their environment. The findings raise concerns about both ecological impacts and potential health risks from consuming contaminated shellfish in this major mussel farming region.
