ClearSpatiotemporal macro debris and microplastic variations linked to domestic waste and textile industry in the supercritical Citarum River, Indonesia
In-situ monitoring of macro debris and microplastics along the heavily polluted Citarum River in Indonesia found that plastics dominated riverine debris (comprising 85% of materials) and that dams were concentrated accumulation points for microplastics. The study links plastic loads to both domestic waste disposal and textile industry discharges along the river.

Researchers analyzed microplastic contamination in sediments from Semarang waters in Central Java, Indonesia, documenting the types, abundance, and distribution of microplastics across multiple sampling campaigns linked to the city's high population density and waste generation.
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.
