Microplastic pollution poses a threat to the life of aquatic organisms. Accumulated microplastics in the digestive tracts of these organisms can hinder growth, affect reproduction, and cause internal organ damage. This research aims to determine the abundance and forms of microplastics in water, sediment, gills, and digestive tracts of Nile Tilapia (Oreochromis niloticus) in Situ Rawa Besar, Depok. Water and sediment samples were collected from three sampling stations in the lake. Five Nile Tilapia samples were taken from each station. Gill and digestive tract samples were digested using 65% nitric acid (HNO3) solution. Twenty liters of water were collected and filtered using a plankton net. Sediment samples were dried in an oven, with 25 grams used for analysis. A saturated NaCl solution was employed to separate microplastics from impurities. One milliliter of the sample was dropped onto a Sedgewick Rafter Chamber, then observed and counted based on microplastic forms under a microscope. The research results in July 2022 indicated that microplastic abundance ranged from 15.00 to 23.33 particles L-1 in water, 20,330.00 to 45,330.00 particles kg-1 in sediment, 182.67 to 593.33 particles ind-1 in gills, and 596.00 to 701.33 particles ind-1 in the digestive tract. These abundances were lower than those in September 2023, ranging from 24.33 to 34.67 particles L-1 in water, 31,000.00 to 65,670.00 particles kg-1 in sediment, 317.33 to 744.00 particles ind-1 in gills, and 844.00 to 1,120.00 particles ind-1 in the digestive tract.

Plastik is a high-stability material resulting from the polymerization of monomers, with a high level of usage. In aquatic environments, plastic undergoes photo-oxidative degradation by UV radiation from the sun and chemical processes, leading to the breakdown of plastic waste into small particles known as microplastics (<5 mm). Microplastic particles have the potential to be ingested by various aquatic organisms, posing a risk to the food chain through biomagnification. This study aims to analyze the characteristics of microplastics in water, sediment, and the flathead grey mullet (Mugil cephalus) in different organs and tissues (muscle, gills, digestive tract) in the Blanakan River Estuary, Subang, West Java, based on their shape, size, and polymer types. Water samples were collected in a volume of 50 L, filtered using a plankton net to obtain a final volume of 1000 mL. Sediment samples were collected using a Vanveen grab and stored in 500 mL jars, while flathead grey mullet samples were collected using bubu (10 individuals). Sediment sample extraction was performed using a saturated NaCl solution with a ratio of 1 (sediment) to 2 (saturated NaCl solution), followed by the addition of a 30% H2O2 + 0.05 M FeSO4 solution in a 1:1 ratio for water and sediment samples. Fish sample extraction involved weighing and placing the tissues and organs in a glass beaker, followed by the addition of a 10% KOH solution in a volume of 50 mL. The water, sediment, and fish samples were then filtered using Whatman filter paper with the assistance of a vacuum pump, and placed in Petri dishes for microplastic identification using an Olympus CX22LED microscope. Polymer analysis of microplastics was performed using Raman Spectroscopy. Kruskal-Wallis and one-way ANOVA tests were used to determine significant differences in the abundance and composition of microplastics (size and shape) in water, sediment, flathead grey mullet, and their respective organs. Spearman and Pearson correlation tests were used to investigate the influence of water and sediment, as well as morphometric values, on microplastic accumulation in flathead grey mullet. The research findings showed an average total abundance of microplastics in water to be 710 ± 183,34 particles meter-3, in sediment to be 879,63 ± 205,13 particles kilogram-1, and in flathead grey mullet to be 210,8 ± 108,80 particles individual-1. When ranked in descending order, the abundance of microplastics in the three parts of the flathead grey mullet were as follows: flesh, digestive tract, and gills. Overall, the most commonly found forms and sizes of microplastics were microplastic fibers and those below 300 µm. The polymer analysis revealed that the microplastics found in the Blanakan River Estuary were dominated by PET (40%),  PP (40%), and PVC (20%). Based on the significant difference test for microplastic abundance among different parts of the flathead grey mullet, no significant differences were found. The Spearman correlation test indicated a correlation between the abundance of microplastics in water and sediment in the Blanakan River Estuary and the abundance of microplastics in flathead grey mullet."

Sampel jaringan kerang sebanyak 10 individu pada tiap stasiun dilarutkan dengan HNO3 65%. Sampel air sebanyak 20 L disaring dengan menggunakan plankton net 300 µm. Sampel sedimen diambil sebanyak 200 g dikeringkan di oven. Masing-masing sampel dijenuhkan menggunakan NaCl agar mikroplastik dapat mengapung ke atas permukaan. Masing-masing sampel (1 ml) diteteskan di atas Sedgwick Rafter Chamber untuk diamati di mikroskop dan dihitung berdasarkan bentuk partikel yang ditemui yaitu fiber, film, fragmen. Hasil penelitian menunjukan kelimpahan mikroplastik tahun 2020 yang terkandung pada air sejumlah 205,55 ± 40,63 partikel L-1, pada sedimen 179.644,44 ± 37.017,07 partikel Kg-1, dan pada jaringan kerang darah 18.657,77 ± 2.979,57 partikel Ind-1. Kelimpahan miikroplastik pada tahun 2021 lebih tinggi sejumlah 219,44 ± 40,29 partikel L-1 pada air, 208.711,11 ± 25.198,70 partikel Kg-1 pada sedimen, dan 20.913,33 ± 3.532,8 partikel Ind-1 pada jaringan kerang darah.

This study aims to analyze the abundance and form of microplastics accumulated in the Anadara granosa blood clam, water and sediment and to analyze differences in the abundance of microplastics in blood, water, and sedimentary clams in Banten Bay during the rainy season in 2020 and 2021. Blood clams sampling, water, and sediment was carried out at 3 different station locations on 27 January 2020 and 15 March 2021 in the rainy season. 10 individual shellfish tissue samples at each station were dissolved with 65% HNO3. A sample of 20 L of water was filtered using a 300 m plankton net. Sediment samples were taken as much as 200 g and dried in the oven. Each sample was saturated using NaCl so that the microplastics could float to the surface. Each sample (1 ml) was dropped onto the Sedgwick Rafter Chamber to be observed under a microscope and calculated based on the shape of the particles encountered, namely fibers, films, fragments. The results showed that in 2020 the abundance of microplastics contained in water was 205.55 ± 40.63 L-1 particles, 179.644.44 ± 37.017.07 Kg-1 particles, and 18.657.77 ± 2.979.57 particles in blood clams. Ind-1 particles. The abundance of microplastics in 2021 is higher by 219.44 ± 40.29 L-1 particles in water, 208.711.11 ± 25.198.70 Kg-1 particles in sediments, and 20,913.33 ± 3,532.8 Ind-1 particles in tissue blood clams.
