Microplastic contamination on Anadara granosa Linnaeus 1758 in Pangkal Babu mangrove forest area, Tanjung Jabung Barat district, Jambi
AI summary Read the abstract
Researchers found microplastics in 100% of blood cockle (Anadara granosa) samples, as well as in sediment and water from a mangrove forest area in Tanjung Jabung Barat, Indonesia, with fiber, fragment, and film types detected at concentrations posing potential food safety concerns.
Abstract Anadara granosa is an important food source for people in Tanjung Jabung Barat District, Jambi. This study uses samples of cockle, sediment and water. The results showed a 100% sample containing microplastic. The types of microplastic found are fiber, fragments and films. The average microplastic amount in A. granosa individuals was 434 ± 97.05 particles/individuals. Fiber is the type of microplastic that is most commonly found in samples of cockles, sediments and water. In the blood cockles sample, fiber was found as much as 180.6 ± 21.22 particles/individual and 4.1 ± 0.43 particles/g cockle. Fiber is also found with high concentration in water samples of 128.3 ± 0.15 particles/L. The river is indicated as a microplastic source to the sea. The station sample 1 in 100 m near the river mouth has a higher microplastic concentration with an average of 448.3 ± 53.92 microplastic/individual, compared to station sample 3 which is only 420.3 ± 42.66 microplastic/individual.

This Indonesian study analyzed microplastic abundance in the digestive tract of blood cockles from Sungsang waters in South Sumatra. Microplastics were found in the bivalves, raising food safety concerns given that cockles are widely consumed in the region.
Keberadaan mikroplastik pada kerang darah (Anadara granosa) dari TPI Tambak Lorok, Semarang
AI summary Read the abstract
Researchers in Semarang, Indonesia, found microplastics in blood cockles (Anadara granosa) sold at a local fish market, with fibers and fragments being the most common types identified under microscopy. The study also tested whether washing the shellfish before analysis affected results, finding contamination was present regardless. Because blood cockles are a widely consumed seafood in the region and are filter feeders that concentrate particles from the water column, this finding signals a direct route for microplastic ingestion by local populations.
