Anadara antiquata and Anadara granosa are important consumption commodities for people in North Sumatra Province, Indonesia. However, information regarding microplastic contamination in these two commodities has never been reported, despite the fact that there is a very significant chance of microplastic accumulation in these two species. This research aims to reveal microplastic contamination in A. antiquata and A. granosa so that people are more aware of the dangers of plastic waste contaminating consumer goods. This research was conducted in Tanjung Balai, Batu Bara, and Langkat districts, North Sumatra Province, Indonesia. The research method was field observation by collecting 50 samples/species/location and then analyzing them at the Biology Laboratory, Universitas Negeri Medan, Indonesia. The results of the analysis of microplastic prevalence based on location and species showed that A. antiquata had values of 88%, 96% and 98% respectively from the locations of Tanjung Balai, Batu Bara and Langkat districts; A. granosa has sequential values of 100%, 100%, and 90% from the locations of Tanjung Balai, Batu Bara and Langkat districts respectively. The highest microplastic intensity value in A. antiquata reached 6.07 particles ind-1 collected from Tanjung Balai District, while for A. granosa it reached 3.32 particles ind-1 collected in Batu Bara District. The analysis results showed that there were three types of microplastics that contaminated the two Anadara species, namely fiber, film and fragments. The results of microplastic analysis based on color showed that seven colors were identified, including black, blue, brown, green, purple, red, and transparent. © 2024, BIOFLUX SRL.
