Ingestion of microplastics by anchovies from east Lombok Harbour, Lombok Island, Indonesia
AI summary Read the abstract
Researchers investigated microplastic contamination in the digestive tracts of anchovies (Stolephorus spp.) from East Lombok Harbour, Indonesia, finding an average of 88 microplastic particles per individual. Fibres (51%) and films (30%) dominated the microplastic morphologies, with FTIR spectroscopy confirming polymers including polypropylene, polystyrene, and polyethylene.
Microplastics (MPs) on the contaminated ocean are highly bioavailable for pelagic fish like anchovies, yet reported on contaminated anchovies from Indonesia is lacking. Here, we have investigated microplastics in digestive tracts of anchovies (Stolephorus spp.) sampled (n = 15) from East Lombok harbour. Total microplastics from contaminated anchovies is 88 ±2.89 particles/individual. Microplastics are detected in different size of range: <20 µm, 20-50 µm, 50-500 µm, 500-1000 µm, and >1000 µm. Most of microplastics shapes are fibre (51%) and film (30%). Polymers types are confirmed by Fourier transform infrared (FTIR) spectroscopy as polypropylene, polystyrene, low-density polyethylene, high-density polyethylene, thermoplastic polyester and foamed polystyrene nylon. Our findings reported that 50-500 µm size is the vast majority of microplastics which are ingested by anchovies. Anchovies are commercials foods and low-tropic level organisms which are supplied as foods for the higher taxa. Human exposure is possible by contaminated seafood diet.

Ingestion of microplastics by anchovies from Talisayan harbor, East Kalimantan, Indonesia
AI summary Read the abstract
Researchers examined microplastics in the digestive tracts of anchovies (Stolephorus spp.) from Talisayan harbor, East Kalimantan, finding an average of 366 particles per individual, with microfilm (50%) and microfiber (30%) as dominant shapes and polypropylene, high-density polyethylene, and foamed polystyrene as the main polymers. The study also detected mercury contamination in the same specimens, raising concerns about combined contaminant burdens in this commercially harvested fish.
Microplastic abundance in anchovy Stolephorus indicus (Van Hasselt, 1823) in the Lada Bay, Pandeglang, Banten
AI summary Read the abstract
Researchers found high concentrations of microplastics averaging 246 particles per individual in anchovies from Lada Bay, Indonesia, along with 156 particles per litre in the surrounding water. Fibres dominated both matrices, indicating that synthetic textiles are a major local source of contamination.
Microplastic contamination in Indonesian anchovies from fourteen locations
AI summary Read the abstract
Microplastic contamination was found in anchovies sampled from 14 locations across Indonesia, with contamination levels varying by location and suggesting that the widespread marine distribution of microplastics poses risks to commercially important small pelagic fish.
Microplastic exposure in anchovies: baseline evidence from small-island waters of Indonesia
AI summary Read the abstract
Researchers checked anchovies from a small Indonesian island for microplastics and found tiny plastic bits, mostly fibers, in almost all the fish, averaging about one particle per anchovy. Since anchovies are typically eaten whole, this means people consuming them may also be swallowing these plastic particles, though this study only measured contamination levels and didn't test health effects. The findings highlight the need for ongoing monitoring and stronger efforts to reduce plastic pollution in our oceans to protect seafood safety.
