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.
Microplastic distribution in surface water and sediment river around slum and industrial area (case study: Ciwalengke River, Majalaya district, Indonesia)

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.
Microplastic distribution in Surface Water and Sediments of Way Belau River, Lampung, Indonesia
This study mapped microplastic distribution in both surface water and sediments of the Way Belau River in Lampung, Indonesia. Microplastics were found throughout the river, with higher concentrations in sediments than in surface water, indicating accumulation in riverbed environments.
Spatial Dynamics of Microplastic Pollution in Water and Sediments of the Ciliwung River along with Conditions of Water Quality Field Parameters and Population Density
This study mapped the spatial distribution of microplastics in water and sediment across Indonesia's heavily populated Ciliwung River, finding significant contamination linked to population density and land use. The dominant types were fragments and fibers from textiles and synthetic materials, with concentrations varying along the river's length. The results underscore the threat that densely settled riverine systems pose as conduits of microplastic pollution into coastal and marine environments.
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.
Occurrence of Microplastics in Kemena River and Niah River of Sarawak, Malaysia
Researchers investigated microplastic occurrence in water and riverbed sediments of the Kemena and Niah Rivers in Sarawak, Malaysia, finding that urbanization along these rivers correlates with higher microplastic concentrations in freshwater environments.
The contribution of estuaries to the abundance of microplastics in Jakarta Bay, Indonesia
Researchers found that rivers draining into Jakarta Bay are a major source of microplastics, with polyethylene fragments in the 300-500 micrometer size range dominating, and that spatial variation in abundance across nine estuaries reflects differences in local land use and waste management.
