Aquatic insects may be at risk due to microplastics, which are new pollutants in the water that known sink and accumulate sediments. In this study, concentration, type, size, color of MPs surface water, sediments, aquatic were investigated rice fields. The MP concentrations 85.8 items/L. sediment 0.43 items/g. predatory insects, microplastics discovered 0.59±0.50–17.00±17.00 items/individual, scrapers 2.45±2.66–9.00±9.00 collector-gathering 2.45±2.66–25.00±25.99 items/individual. Fibers predominant type sediment, insects. most common sizes <100 µm >500 200-250 water. dominant colors detected blue white/transparent sediment. Polyethylene terephthalate (PET), polyvinyl acetate (PVAc), polypropylene glycol (PPG), polyethylene (PEG), poly (acrylamide-co-acrylic acid) (poly (AM-co-AA), (vinyl methyl ether) (PVME), bis(2-ethylhexyl) phthalate (DEHP) major polymer types selected particles. results study showed concentration fields is relatively high insect samples, although it lower samples. This data assist extending our knowledge regarding pollution freshwater systems provides a baseline for future monitoring assessment
