Heavy metal and microplastic contamination in green mussels (Perna viridis) collected from an important aquaculture area in Java, Indonesia: Bioaccumulation and risk assessment
AI summary Read the abstract
Scientists tested green mussels from Indonesian fish farms and found that most heavy metals in them were at safe levels for eating, except lead, which was slightly above the recommended limit. However, the mussels also contained tiny plastic particles (microplastics) made from eight different types of plastic, and researchers rated the potential hazard from these plastics as high—meaning that while the metals alone may not pose a major risk, the combined effect of eating seafood contaminated with both metals and plastic particles is still a health concern worth watching.
The present study analyzed the potential health effects of co-exposure to heavy metals (HMs) and microplastics (MPs) in green mussels, Perna viridis , which are cultivated in important areas throughout Indonesia's northern Java coastline. The findings showed that, with the sole exception of Pb, which is slightly exceed the permissible upper limits, the levels of most HMs (Cd, Hg, Cr, Cu, and As) found in the tissues of green mussels fall within the acceptable upper thresholds set by the various international bodies. The level of HMs analyzed in the tissues of green mussels were found to be below the provisional tolerable weekly intake levels. The observed levels for the target hazard quotient and hazard index concerning Pb, Cd, Hg, Cr, Cu, and As in the green mussels’ tissues were observed to be below 1. This indicates neither single heavy metal as well as their collective existence causes a substantial non-carcinogenic threat to consumers. The established cancer risk levels for arsenic, lead, and chromium fall within the permissible thresholds, suggesting an absence of potential carcinogenic risk to humans. The tissue of P. viridis at the Semarang site exhibited the lowest level of MPs, while the MPs concentrations in the tissues from the Pasuruan, Gresik, and Jakarta sites showed no significant differences. The MPs detected within the tissues of green mussels at all examined locations were primarily comprised of black particles measuring under 100 µm. In the tissues of green mussels, eight distinct polymer types have been identified: polyurethane, polyethylene, polypropylene, polyamide, polystyrene, polyvinyl chloride, polyvinyl alcohol, and polymethyl methacrylate. All four study sites exhibited a polymer hazard index classified as III, signifying a high hazard category.

Characterization of microplastics and associated metals in green mussel cultivation: Estimation of potential health risks
AI summary Read the abstract
Researchers examined 120 green mussels from Jakarta and found microplastics in every single sample, with an average of 18 particles per mussel along with aluminum and lead contamination on particle surfaces. The study identified 15 different polymer types, some classified at hazard levels considered dangerous to human health. Based on consumption patterns, the estimated annual human intake of microplastics from these mussels ranged from about 10,000 to 76,000 particles across different age groups.
Microplastic contamination in green mussels (Perna viridis Linnaeus, 1758) collected from the traditional fish markets along the East Java coast of Indonesia and the associated risk assessment
AI summary Read the abstract
Researchers analyzed green mussels from five traditional fish markets along the East Java coast of Indonesia and found microplastic contamination in all samples, primarily in the form of fibers and fragments smaller than 500 micrometers. The polymer hazard index ranged from high to very high across all market locations, and various harmful chemicals associated with plastic production were detected in the mussel tissues. The findings raise health concerns for communities that regularly consume these mussels as a dietary staple.

The characteristics of microplastics and the associated metals on the surfaces of microplastics in green mussels (Perna viridis) collected from different water depths in the Bekasi Estuary, West Java, Indonesia
AI summary Read the abstract
Researchers evaluated microplastics and associated metals in green mussels collected from different water depths in the Bekasi Estuary, Indonesia. They found that fragment-type microplastics smaller than 100 micrometers were most common, with eight different polymer types detected including PVC, polycarbonate, and polystyrene. Multiple metals including aluminum, chromium, copper, zinc, arsenic, cadmium, mercury, and lead were found adhered to the microplastic surfaces, raising concerns about combined contamination in this estuarine ecosystem.
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.
