Microplastic contamination on Anadara granosa Linnaeus 1758 in Pangkal Babu mangrove forest area, Tanjung Jabung Barat district, Jambi

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.
