Characteristics and Abundance of Microplastics Pollution in Water and Sediment in the Bogowonto River
Sampling of Indonesia's Bogowonto River found microplastic concentrations of 127–253 particles per cubic meter in water and 100–237 particles per kilogram in sediment, with fibers the dominant shape and polyamide and polypropylene the most common polymer types. The study identifies agricultural runoff, hospital waste, and domestic sewage as key sources, and shows that the river's meander pattern concentrates microplastics at certain locations — information useful for targeting mitigation efforts.
Temporal Variation of Microplastic Abundances and Characteristics in Surface Water of Banger River of Pekalongan City, Indonesia
A time-series study of the Banger River in Pekalongan, Indonesia — an industrial batik textile hub — found microplastics throughout the river system with varying abundances across sampling periods. The findings confirm that textile industry discharge is a major source of river microplastic contamination, which ultimately flows into coastal waters and the food chain.
Estimation of Laundry-derived Microfiber Discharges into Wastewater: A Case Study in Hanoi City
Researchers analyzed 30 household laundry wastewater samples from Hanoi, Vietnam, finding extremely high microplastic concentrations averaging 96,296 particles per cubic meter, with fibers making up 99.6% of all particles and 12 polymer types identified.
Pervasiveness and characteristics of microplastics in surface water and sediment of the Buriganga River, Bangladesh
Researchers investigated microplastic contamination in the Buriganga River in Bangladesh, finding concentrations of 4.33 to 43.67 items per liter in surface water, with fibers and fragments as dominant types linked to textile industries and urban waste discharge in the Dhaka megacity.
Characterization of Microplastics in Jakarta’s Urban Downstream and Estuary Water Bodies
Researchers characterized microplastic contamination in urban water bodies of Jakarta -- specifically Sunter River, Buaran River, and Marunda Estuary -- which serve as conduits for plastic waste to the ocean. Microplastics were abundant in all sampled water bodies, with fiber and fragment morphotypes dominant, reflecting the high density of urban plastic sources in the surrounding catchments.
Microplastics in wastewater treatment plants of Wuhan, Central China: Abundance, removal, and potential source in household wastewater
Two wastewater treatment plants in Wuhan, China, removed 62-66% of incoming microplastics, and household sources including clothing laundering, facial cleansers, and toothpaste were identified as dominant contributors. Washing one kilogram of clothing released over 150,000 fibers, making laundry the largest single household microplastic source.
Assessment of Small-Scale Microplastics Abundance and Characterization in Urban River: A Case Study in Metro River, Indonesia
Researchers assessed microplastic contamination in the Metro River in Indonesia, finding that abundance and characteristics varied by land use type, with urban areas showing higher concentrations of fragments and fibers in this rapidly developing region.
A novel report on the occurrence of microplastics in Pekalongan River Estuary, Java Island, Indonesia
Researchers measured microplastic contamination in water and sediments of the Pekalongan River estuary in Indonesia, finding concentrations of 45.2-99.1 particles/L in water and 0.77-1.01 particles/g in sediment. Polystyrene, polyester, and polyamide were the dominant polymers, with fragments and films smaller than 1 mm accounting for the majority.
