Analysis of Abundance and Distribution of Microplastics in Sediments of Sail River, Pekanbaru City, Riau
Researchers analyzed sediment samples from the Sail River in Pekanbaru, Indonesia, and found microplastic contamination at all sampling stations, with abundance increasing toward downstream areas. Concentrations ranged from 5,335 to 21,374 particles per kilogram of dry sediment, consisting of fragments, fibers, and films. The study suggests that growing urban activities such as housing, shops, and restaurants along the river are contributing to the increasing microplastic pollution.

Distribution of microplastics in Surabaya River, Indonesia
Microplastics were found at all sampling depths in the Surabaya River, Indonesia, with surface waters having the highest concentrations and film-shaped large particles predominating. The study confirms that one of the world's most plastic-polluted rivers carries plastics throughout its water column, not just at the surface.

Researchers investigated microplastic contamination in the Cisadane River, Indonesia, finding 13 to 113 particles per cubic meter in surface water with higher abundance downstream, dominated by polyethylene, polystyrene, and polypropylene fragments from household and industrial sources.
Abundance and Distribution of Microplastics in the Water and Riverbank Sediment in Malaysia – A Review
Microplastic abundance and distribution were surveyed in the water column and riverbank sediments of a Malaysian river. Results showed microplastics throughout the river system, with fiber shapes dominating in water and fragments more common in sediments, reflecting contributions from domestic wastewater and plastic litter.
Unraveling Microplastic Presence in Freshwater and Sediment of Rejoso River, Indonesia
Researchers investigated microplastic presence in water and sediment of the Rejoso River in Indonesia across 12 sampling sites, characterizing the types, abundances, and distribution patterns of microplastic particles in this tropical freshwater system.
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.
Microplastic pollution in the water and sediment of Krukut River, Jakarta, Indonesia
Researchers collected water and sediment samples from upstream, middle, and downstream sites in the Krukut River in Jakarta, Indonesia, and used density separation and microscopy to quantify microplastics. They found that microplastic abundance increased downstream, with fibers dominating in water and pellets in sediment, and downstream concentrations reaching 265 particles per 100 mL in water and 150 particles per kg dry weight in sediment.
Microplastic distribution in surface water and sediment river around slum and industrial area (case study: Ciwalengke River, Majalaya district, Indonesia)
Microplastics were surveyed in surface water and sediments of the Ciwalengke River in Indonesia across slum and industrial areas, finding average concentrations of 5.85 particles/L in water and 138 items/kg in sediment with fibers as the dominant form. The study is the first to examine microplastic contamination in a slum-dominated Indonesian river environment, documenting high concentrations linked to informal waste disposal.
Distribution of Microplastic Abundance and Composition in Surface Water around Anthropogenic Areas (Case Study: Jeneberang River, South Sulawesi, Indonesia)
Researchers collected surface water samples from eight stations along the Jeneberang River in South Sulawesi categorised by land use type, finding microplastic concentrations ranging from 2.00 to 5.77 particles per litre with microfibers as the dominant morphotype and highest concentrations near a traditional market site approximately 60 metres upstream.
Spatial–Vertical Distribution of Microplastics Abundance and Characteristics in the Coastal Waters of Raha City, Muna Regency
Researchers mapped the spatial and vertical distribution of microplastics in the coastal waters of Raha City, Indonesia, sampling at three stations representing different human activity levels. The harbor area showed the highest microplastic abundance, and concentrations were generally higher at the surface and mid-water layers than near the bottom. The study confirms that fisheries and harbor activities, along with river-carried waste, are major sources of microplastic pollution in these coastal waters.
