Mikroplastik dalam Kerang Darah (Anadara granosa) pada Ukuran yang Berbeda di Perairan Kwanyar Kabupaten Bangkalan Madura
AI summary Read the abstract
Indonesian researchers quantified microplastics in blood cockles (Anadara granosa) of different sizes collected from Kwanyar, Madura, comparing contamination near mangroves, river estuaries, and settlements. The study found microplastic concentrations varied by location and shell size, with fibers dominating the types found.
Microplastic is plastic waste that has a small size of less than 5 mm. Microplastic itself has a dangerous impact due to the nature of plastic which is difficult to decompose. The purpose of this study is to determine the shape, average number and highest weight, total amount, type of microplastic polymer and comparison between sizes of Anadara granosa in locations near mangroves, river estuaries and settlements in the waters of Kwanyar Bangkalan, Madura. Microplastic analysis of Anadara granosa samples was carried out using a 10% KOH solution as much as 3x the weight of the sample. Identification of microplastics in all samples to determine their shape using a stereo microscope, followed by counting the number and weight. The predominant form of microplastic is fiber. The highest average number of microplastics in Anadara granosa was found at location near the mangrove ecosystem, namely 23.9 particles / individual at 3 cm in size. There was a significant difference in the number of microplastics at different sizes of shells. The types of red, black and blue fiber polymers are Poly (Ethylene Terephthalate), blue film is Polypropylene and blue fragment is Poly(Ethylene Terephthalate).

Researchers identified microplastics in blood cockles (Anadara granosa) from Tanjung Tiram in Ambon Bay, Indonesia, finding 360 fiber particles and 61 fragment particles in examined specimens. The presence of microplastics in this commercially consumed shellfish raises concerns about chemical transfer to both marine biota and human consumers.

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.
