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.
This study aimed to identify the presence of microplastics in green mussels (Perna viridis), surface seawater, and beach sediment on the North Coast of Vietnam. The average concentration of MPs in mussels was 3.67 ± 1.20 MPs/g wet weight and 25.05 ± 5.36 MPs/individual. Regarding surface seawater and beach sediments, the MPs concentration was found at 88.00 ± 30.88 MPs/L and 4800 ± 1776 MPs/kg dry weight, respectively. The dominant microplastics shape was fragment with the fractions ranging from 69.86 to 82.41 %. In addition, the size distribution of MPs was mostly in the range of smaller than 50 μm and 1-150 μm (34.17 % and 45.62 % in mussels; 29.65 % and 43.20 % in surface seawater and 40.22 % and 39.40 % in beach sediment, respectively). Polyethylene terephthalate was the major polymer types 49.93-58.44 % of the detected MPs. The risk assessment results based on the polymer types indicated a warning level in several sites.

Contamination of microplastic in bivalve: first evaluation in Vietnam
AI summary Read the abstract
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.
Microplastic contamination in filter-feeding bivalves inhabiting the natural ecosystem of Da Nang Bay: An investigation of oysters (Ostrea rivularis) and green mussels (Perna viridis)
AI summary Read the abstract
Researchers found microplastics in 100% of examined oysters and green mussels from Da Nang Bay, Vietnam, with average densities of 3.5 items per gram of tissue, exceeding average contamination levels seen in seafood across Asia. Mussels showed considerably higher MP accumulation than oysters, with black plastic particles under 0.5 mm in fibrous form being the dominant type found.
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

Researchers assessed microplastic contamination in seawater, sediments, and green mussels (Perna viridis) around Sri Racha Bay, Thailand, finding seasonal variation with higher levels during the wet season and confirming that mussels bioaccumulate microplastics from their surrounding environment.
