ClearMicroplastic Pollution in Waters and Sediments in a Lentic System: A Case Study in a Tropical Wet Urban Lake of Samarinda, Indonesia
Researchers sampled water and sediment from a tropical urban lake in Samarinda, Indonesia, finding microplastic contamination at all 10 sampling sites with an average of 0.91 particles per litre in water and 375 particles per kilogram in sediment. Fibres — likely from textiles — dominated in both water and sediment, and polyethylene was the most common polymer identified. The study highlights how urban lakes in rapidly developing tropical cities are becoming significant repositories of microplastic pollution, driven by inadequate waste management infrastructure.
Assessment of microplastic on tropical tidal lake waters in Medan (study cases-Siombak lake)
Researchers assessed microplastic pollution in Siombak Lake, a tropical tidal lake in Medan, Indonesia, sampling water and sediments and characterising particles by Raman spectroscopy and microscopy. They found concentrations of 91-126 particles per 100 mL of water and 262-398 particles per gram of dry sediment, dominated by fragment shapes and composed primarily of polyethylene, polypropylene, and polystyrene, with a strong correlation between water and sediment concentrations.
Analysis of Microplastic Content in Surface Water of the Gajah Mungkur Reservoir in Indonesia
Researchers analyzed surface water from Indonesia's Gajah Mungkur Reservoir, a drinking water source, and found microplastics at every sampling location, with concentrations ranging from 340 to 820 particles per cubic meter. The dominant shapes were filaments and fibers, and the plastics identified included polypropylene and polystyrene. The highest contamination was found at an upstream river inlet, suggesting that rivers are a key delivery route for microplastics into the reservoir. The findings raise concerns about microplastic exposure through drinking water drawn from Indonesian surface water sources.

This study investigated microplastic contamination in Kaptai Lake, the largest artificial lake in South Asia, and found concentrations ranging from 650 to 2,450 items per cubic meter in water and 135 to 607.5 items per kilogram in sediment. The majority of identified microplastics were small fibers less than 0.5 mm, with spatial variation influenced by polymer properties, local geography, and pollution sources.
Analysis of Microplastic Abundance in Lake Siombak, Medan Marelan, Medan
Researchers analyzed microplastic abundance in water, sediment, and fish from Lake Siombak in Medan, Indonesia, sampling from November 2021 to January 2022 using density separation and visual microscopy methods. Microplastic concentrations ranged from 93–519 particles/m3 in water, 521–1,481 particles/kg dry sediment, and 0–6 particles per individual fish, highlighting the lake's role as a microplastic distribution channel to coastal waters.
