Analysis location of microplastics in green mussel’s Perna viridis Gills (Linnaeus, 1758)
AI summary Read the abstract
Researchers identified the location, type, and size range of microplastics found in the gill tissues of green mussels collected from Kamal Muara in North Jakarta, Indonesia. The detection of microplastics specifically within gill tissue suggests that these particles penetrate beyond the digestive system and may cause direct tissue-level harm in filter-feeding molluscs.
Abstract This study describes the location, type, and range of microplastic sizes found in the gills of green mussel Perna viridis. This study continues the results of Fathoniah’s research on 2017 about microplastic abundance in green mussels at Kamal Muara, North Jakarta. Sample of 3 green mussels with a size of about 7 cm was taken from Kamal Muara. Gills from both the outer and inner demi branch were isolated and made as preparations. Every part of the gills marked into posterior, anterior, proximal, and distal. After that, the gills were observed under the light optical microscope. Position and type of microplastic in the gills was recorded and measured using the LAZ EZ application. The results showed that the distal area of the gill contains more microplastic than proximal. The dominant microplastic group found in the gills of green mussels was fiber. The range of microplastic sizes found in green mussel’s gills was 20-4500 μm.

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's Contamination in the Hemolymph and Organs (Gills and Hepatopancreas) of Perna viridis
AI summary Read the abstract
Microplastics were detected in the hemolymph (blood), gills, and hepatopancreas (liver equivalent) of green mussels collected from two sites in South Sulawesi, Indonesia, a species widely eaten by local communities. Finding microplastics in both the circulatory fluid and internal organs — not just the digestive tract — indicates systemic distribution within the animal's body, which increases the likelihood that consumers are ingesting plastic particles when eating these mussels.
Identification of Microplastics in the Hepatopancreas of Green Mussels (Perna viridis) in Gunung Jati Waters, Cirebon, West Java
AI summary Read the abstract
Researchers found microplastics accumulating in the hepatopancreas of green mussels (Perna viridis) at two sites in Cirebon, Indonesia, with smaller mussels retaining up to five times more particles per gram than larger ones and fibers dominating at 95–100% of particles, pointing to these bivalves as reliable pollution bioindicators.

Researchers found microplastic contamination in green mussels (Perna viridis) from Lampung Bay, Indonesia, with mean whole-tissue abundance of 0.53 particles/g, gill organs containing significantly more microplastics than digestive organs, and fiber fragments under 100 µm being the most common type.
Abundance of microplastic in green mussel Perna viridis, water, and sediment in Kamal Muara, Jakarta Bay
AI summary Read the abstract
Researchers measured microplastic abundance in green mussels, seawater, and sediments from a harbor in Jakarta Bay, Indonesia, finding microplastics in all three matrices. The correlation between microplastics in mussels and the surrounding environment confirms that these edible shellfish accumulate plastic from their habitat.
