Microplastic Characteristic Found in Gastrointestinal Tract of Pelagic and Demersal Fishes in Tuban, East Java
AI summary Read the abstract
Researchers found microplastics in the gastrointestinal tracts of both pelagic and demersal fish species, documenting plastic ingestion across different feeding guilds and ocean depths. The study adds to growing evidence of widespread microplastic contamination throughout marine food webs.
Regular monitoring of microplastics contamination in marine biota have been concerned in the world, since its tiny size can be swallowed direct or indirectly and lead health problems. Tuban waters is the one of Indonesia's coastal and marine fisheries areas with high risk of microplastic pollution due to their highly anthropogenic activities. We investigated the microplastic in the digestive tracts of pelagic and demersal fishes in Tuban sea waters. Microplastic in fish sample guts were observed under microscope and the type of polymer were examined using FT-IR. This study reveals that number of microplastic in digestive tract of pelagic fishes were higher than demersal fishes. The dominant form was fiber (62%) with black color and dominant size ranging from 100-500 um (72%). The types of polymers found were polyethylene and polyamide.
