Microplastic in Several Fishes at Banyusangka Waters
AI summary Read the abstract
Indonesian researchers identified and quantified microplastics in the digestive systems of three fish species (tuna, mackerel, and hairtail) from Banyusangka waters. The study found microplastic contamination across all three species, with fiber being the most common particle type.
The purpose of this study was to determine the shape, amount, and weight of microplastics in each sampel of Tuna fish (Euthynnus sp.), Bloated fish (Rastrelliger sp.), And Layur fish (Trichiurus sp.) which have obtained, and to know the comparison of microplastics between fish. The analysis method is random sampling with a 2x sampling period, and continued with laboratory analysis. The fish organs which analyzed were focused on the digestive system by the addition of 10% KOH by 1: 3 sample weight. The filtering results are then observed in a stereo microscope to determine the shape and amount of microplastics and weighing in an analytical balance. The results of the analysis found microplastics in the form of fiber, fragments, and films, with the dominance of the total number of microplastic findings in a row is in tuna, mackerel, and layur fish. Anova analysis was conducted which found that there was no difference of microplastic between fish.

Identification of Microplastic in the Digestive Tracts of Mackerel Tuna, Lemuru and Sea Water from Pangandaran, Indonesia
AI summary Read the abstract
Researchers examined the digestive tracts of mackerel tuna and lemuru fish from coastal waters in Pangandaran, Indonesia, and found microplastics in both species. Mackerel tuna contained mostly fragment-type microplastics while lemuru had primarily fiber-type particles, with polypropylene and polyester identified as the dominant polymer types. The study highlights the extent of microplastic contamination in commercially important fish species and the potential for human exposure through seafood consumption.
