Microplastic in mangrove horn snail Telescopium telescopium (Linnaeus, 1758) at mangrove ecosystem, Rambut Island, Jakarta Bay, Indonesia

Abstract This study was done to identify the type and amount of microplastic particle in the sediment, water and the horn snail Telescopium telescopium (soft tissue, respiratory and digestive organs) in the coast of Rambut Island, Jakarta. This research also aimed to know the correlation between the amount of microplastic particles in the sediment and the snail body mass. The result showed that average amount of microplastic were found 764.81 particles/ind in the snail, 31.7 particles/g in sediment and 15.46 particles/mL water samples. The microplastic type of film was dominant in all of the samples, with average amount 368.51 particles/ind in snail, 15 particles/g sediment and 9.46 particles/mL water samples, respectively. The respiratory organ contained higher microplastics (102.33 particles/ind) than the digestive organ (66.85 particles/ind). There were significantly positive correlation (r=0.744) between amount of microplastics in the snail and the snail body mass.
