Analysis of Microplastic Content in Consumable Fish at The Fish Landing Port (PPI) Banjarmasin, South Kalimantan

Abstract

Abstract Microplastics that enter the tissues of marine organisms are included in their bloodstream and accumulate in their bodies. Over time, certain amounts and doses of microplastics become toxic and threaten the survival of these organisms. Therefore, microplastics are currently receiving special attention in the field of water pollution studies due to their unique nature compared to other pollutants. The research samples were collected from the Fish Landing Port (PPI) Banjarmasin, South Kalimantan. Sampling was conducted between April and September 2023. Demersal fish species, including Epinephelus sexfasciatus, Nemipterus nematophorus , and Gazza minuta , were collected using a purposive sampling method. In total, 30 individuals were collected, consisting 10 of individuals of E. Sexfasciatus , 10 individuals of N. Nematophorus , and 10 individuals of G. Minuta. The digestive tracts were digested using a 20% KOH solution, and microplastic characteristics were analyzed using stereo microscopy. Polymer testing was conducted using the Fourier Transform Infrared (FTIR) method. Morphometric analysis of the fish indicated lengths ranging from 13 cm to 23 cm and weights between 36.4 g and 203.6 g. The species N. nematophorus showed the highest microplastic contamination at 40%, while G. minuta had a contamination rate of 10%. The color proportion of microplastics in fish samples from demersal habitats was identified. E. sexfasciatus had 100% blue microplastics, N. nematophorus had 40% blue, 20% brown, and 40% black microplastics, and G. minuta had 100% black microplastics.. The polymers detected in the demersal fish samples consisted of polystyrene (PS) and polypropylene (PP).
