Characterization of microplastic in trawl fish caught in Padang City (Indonesia) coastal area

Abstract. Edwin T, Primasari B, Purnama RA. 2023. Characterization of microplastic in trawl fish caught Padang City (Indonesia) coastal area. Biodiversitas 24: 516-522. Marine organisms can ingest microplastics that are distributed the oceans. It harm marine because carcinogenic materials easily attach to microplastics. Trawl is a commercial with high demand from people City, West Sumatera, Indonesia. This study aimed analyze abundance gastrointestinal tract fish. Also, characteristics on Pasir Jambak Coast and Purus City. The species studied were Sulphur goatfish (Upeneus sulphureus), Indian mackerel (Rastrelliger kanagurta), White sardinella (Sardinella albella). Microplastics identified using microscopy FTIR spectroscopy. Microplastic goatfish, mackerel, was 3.89±1.36 per fish, 4.22±1.28 particles 2.50±0.46 respectively. size most commonly found ranged 1-5 mm categorized as Large (LMP) type. Fourier Transform Infra-Red (FTIR) spectroscopy analysis showed origin type polymer Polyethylene Terephthalate (PET). Statistically, it shows difference location time sampling does not provide significant concentration seawater. results this indicated waters all samples coast studied. be used manage plastic waste city prevent worse impact due pollution future.
