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.
Microplastic pollution is a significant global environmental concern affecting marine ecosystems and human health. This study investigated the presence and abundance of microplastics in the waters and green mussels (Perna viridis) of the Kalirejo coastal area in East Java, Indonesia, a region known for extensive mussel cultivation. The results showed that microplastics were present in all water and mussel samples, with higher concentrations at shallower depths. Fragments were the most prevalent microplastic type, followed by fibers and films, with polyethylene (PE) identified as the dominant polymer. A strong positive correlation between microplastic concentrations in water and mussel tissues indicates direct environmental uptake. These findings highlight widespread microplastic contamination in the Kalirejo coastal area, raising concerns about environmental impacts and health hazards associated with consuming contaminated shellfish.

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 RELATIONSHIP OF MICROPLASTIC ABUNDANCE IN GREEN MUSSEL Perna viridis AND THE WATERS OF MANGKANG BEACH, SEMARANG
AI summary Read the abstract
A study of green mussels (Perna viridis) farmed in a coastal area of Semarang, Indonesia found microplastics in both the surrounding water and mussel tissue, with statistical analysis confirming a significant relationship between water contamination levels and mussel body burden. Because green mussels are widely consumed locally, this finding highlights a direct pathway for microplastic exposure through seafood in the region.
Microplastic contamination in green mussels (Perna viridis Linnaeus, 1858) from traditional seafood markets in Jakarta, Indonesia, and an evaluation of potential hazards
AI summary Read the abstract
Researchers examined green mussels sold at traditional seafood markets in Jakarta, Indonesia, and found microplastic contamination in every sample tested. The most common types were black fibers made of polymers like rayon and polyethylene, with chemical analysis revealing potentially harmful additives. Since mussels are filter feeders that concentrate particles from seawater, eating contaminated shellfish is a direct route for microplastic exposure in humans.

Contaminants and Human Health Risks Associated with Exposure to Microplastic Ingestion of Green Mussels (Perna viridis) Collected from The Kedonganan Fish Market, Bali
AI summary Read the abstract
Researchers analyzed green mussels sold at a fish market in Bali, Indonesia, and found microplastics in the form of lines, fragments, filaments, and films across all samples. Black-colored particles were the most prevalent, and estimated annual microplastic intake through mussel consumption in Indonesia reached nearly 500,000 particles per person. The findings raise concerns about dietary exposure to microplastics through commonly consumed seafood in the region.
