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.
Levels of Microplastics in Aquatic Ecosystem Components of the Kedung Ombo Reservoir, Central Java: Analysis of Water, Tilapia (Oreochromis mossambicus), Sediment, Macroalgae, and Gastropods
