Microplastics contamination in the green mussels (Perna viridis) cultured for human consumption in Thailand
AI summary Read the abstract
Researchers investigated microplastic contamination in green mussels farmed for human consumption at two sites in Thailand's Gulf coast. They found microplastics in 100% of water, sediment, and mussel samples, with fibers being the most common shape and polyethylene terephthalate the most frequent polymer type. The study estimates that Thai consumers eating mussels could ingest thousands of microplastic particles annually, highlighting the need for monitoring aquaculture products.
Recent trends in the aquaculture industry have introduced massive quantities of microplastics (MPs). This study investigated the MPs contamination in green mussel (Perna viridis) farms located on the east (Sriracha Bay) and west (Phetchaburi) sides of the Gulf of Thailand. The abundance and characteristics of MPs were determined by Nile Red tagging while polymer composition was determined by micro-Fourier Transform Infrared Spectroscopy. MPs were detected in water, sediments, and mussels with 100% detection frequency. The average abundance of MPs in water, sediments, and green mussels at Sriracha Bay was 41.5 ± 6.0 particles/L, 474.6 ± 102.6 items/kg, and 3.2 ± 1.6 items/individual, respectively while it was lower at Phetchaburi. Fragments were dominant morphotype while high-density polyethylene was the dominant polymer. No significant difference was found between the young and older mussels while a significant difference was observed in mussels between the two farms. Policies should be implemented to reduce the MPs contamination in aquaculture environments.

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
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.
