“…The majority (63%) of the MPs found in organisms were classified as microfibers, this result is consistent with those of Celik (2021), Makhdoumi et al (2021) andPan et al (2021). According to the literature, microfibers are considered as the major marine pollutant throughout the world.…”

Microplastics (MPs) defined as ‘small’ pieces of plastic < 5 mm have been found in almost every marine habitat around the world, and studies have shown that we can find them in the ocean surface, the water column, the seafloor, the shoreline, in biota and in the atmosphere-ocean interface. This study aimed to assess both marine and freshwater environments of Cocos Island, Costa Rica, in the Pacific Ocean, by sampling sediments and biota to determine the presence and abundance of this pollutant. Sediment samples were superficial and weighed one kilogram each. For the sampling of freshwater fish and shrimps, nonselective capture with small nets was made in rivers with access by land, while fishing rods were used for the marine fish sampling, and cage and scuba diving for lobsters. Plastics were found in all types of samples: 93% of marine sediments, 32% of freshwater sediments, 20% of freshwater fish, 15% of freshwater shrimps, 27% of marine fish, and 51% of marine lobsters. Like many reports around the world, it was expected to find MPs at marine samples, and it was concluded that ocean currents, tourism activities, and discarded fishing gear from illegal fishing activities could be the sources of marine pollutants. In contrast, the amount of MPs found in freshwater environments was not expected. Their possible sources are unclear at this moment.

“…Previous studies have shown that most microplastic contamination is detected in inedible tissues of fish, such as gut organs [6,81]. However, currently, there are some other studies also showing that microplastic contamination is detected in the edible tissues of fish, including skin and muscle tissue [82,83]. However, the mechanism by which microplastics remain in fish muscles remains unclear.…”

Indonesia is among the largest fish-producing countries. The West Nusa Tenggara (WNT) region is one of the highest producers of fish in Indonesia. Hence, the levels of MP contamination in commercial fish should be assessed to ensure food safety, food security, and socio-economic sustainability. This study investigates MP contamination in commercial fish in one of the largest fish markets in the WNT region, the Bintaro fish market. Three commercial fish species were evaluated for MP contamination in this study, Nasso thynnoides, Auxis rochei, and Caesio teres. The highest number of MPs was detected in A. rochei (21.60 ± 8.70 MPs/100 g). The other pelagic fish species, N. thynnoides, also shown considerably high MP contamination (18.17 ± 7.93 MPs/100 g). On the other hand, the midwater fish Caesio teres showed the least MP contamination (7.07 MPs/100 g). In addition, most of the MPs detected in all three fish species were fiber MPs of small sizes (100–500 µm). Based on FTIR analyses, the MP samples from all three fish species mainly consisted of polyamide (PA), which is the polymer used to form fiber for textiles. These results potentially reveal the degree of microplastic pollution in not only coastal areas of WNT, but also Sulawesi and also East Nusa Tenggara (ENT) since the fish distributed at the Bintaro fish market came from these regions. Better solid waste management in Indonesia is needed to reduce plastic waste management, particularly household waste, which is the potential major source of fiber MPs.

Abstrak-Mikroplastik (MPs) merupakan polimer sintetis berukuran kurang dari 5 mm. Peningkatan limbah plastik di perairan dan kecilnya ukuran MPs menyebabkan potensi untuk masuk dan terakumulasinya MPs tersebut dalam tubuh ikan. Bioakumulasi MPs dapat menimbulkan dampak fisiologis negatif terhadap ikan dan juga konsumennya, termasuk manusia. Penelitian ini ditujukan untuk mengetahui bioakumulasi MPs pada daging ikan Nila (Oreochromis niloticus) periode 1 (umur 2 bulan) dan periode 2 (umur 4 bulan) setelah tebar di Keramba Jaring Apung (KJA) di Ranu Grati, Pasuruan; juga membandingkannya dengan konsentrasi MPs di air dalam KJA. Parameter pengamatan adalah jumlah dan karakter fisik (bentuk, ukuran dan warna) MPs. Perbandingan konsentrasi MPs pada ikan nila periode 1 dan periode 2 akan dianalisis dengan uji Mann Whitney U pada selang kepercayaan 95%. Sampel air KJA pada periode 1 dan periode 2 menunjukkan kelimpahan MPs sebanyak 12 partikel/100 liter dan 21 partikel/100 liter dengan panjang rata-rata panjang 958,57 µm dan 922,09 µm secara berturutturut, sebagian besar dalam rentang ukuran 100-1000 µm. Sampel air KJA pada kedua periode menunjukkan dominasi bentuk MPs fiber dan warna MPs biru. Sampel daging ikan nila pada periode 1 dan periode 2 menunjukkan kelimpahan MPs 510 partikel dan 330 partikel dengan panjang rata-rata 1404,5 + 1481,7 µm dan 1028,9 + 1009,4 µm secara berturutturut, sebagian besar dalam rentang ukuran 1000-5000 µm. Jumlah MPs per satuan massa pada grup periode 1 adalah 2,1 partikel/g; jumlah MPs per satuan massa pada grup periode 2 adalah 0,3 partikel/g. Sampel daging pada kedua periode menunjukkan dominasi bentuk MPs fiber dan warna MPs biru.
