Researchers conducted an initial investigation of microplastic pollution in river sediments crossing Yogyakarta City in Indonesia, finding microplastics at all sampling sites. Fragment and fiber types dominated, reflecting common plastic pollution sources in this urban environment.
Assessment of Microplastic Pollution in Surface Water within a Densely Populated Area of the Kranji River Basin in Purwokerto, Indonesia
Researchers assessed microplastic pollution in the surface water of the Kranji River Basin in Purwokerto, Indonesia, a densely populated urban area, characterising particle abundance, morphology, colour, and polymer type. The study documented widespread microplastic contamination and identified key sources associated with urban population density, waste management practices, and proximity to human settlements.
Identifikasi Kelimpahan dan Karakteristik Mikroplastik pada Air Kali Mas, Kota Surabaya
This Indonesian study characterized microplastic abundance and type in water from the Kali Mas river in Surabaya. Plastic fragments and fibers were detected throughout the urban waterway, reflecting the impact of dense residential and commercial activity on local water quality.
Occurrence and visual characterization of microplastics from Mahakam River at Tenggarong City, Indonesia
Researchers detected and visually characterized microplastics in water samples from the Mahakam River near Tenggarong City, Indonesia, contributing to limited freshwater microplastic data from the country that produces approximately 7.8 million tons of plastic waste annually. Microplastics were found in river samples, with fiber and fragment morphotypes dominant, reflecting local plastic waste mismanagement.
Microplastic pollution in Surabaya River Water and Aquatic Biota, Indonesia
Researchers surveyed microplastic contamination in the Surabaya River and its aquatic organisms in Indonesia, finding MPs in water, sediment, and multiple fish species, with fiber concentrations highest near densely populated urban areas and fish tissue contamination raising concerns for human exposure through seafood consumption.
Effect of Anthropogenic Type and Depth on Microplastic Abundance in Mahakam River Water, Samarinda City
This Indonesian study measured microplastic concentrations in water from the Mahakam River at different depths and near different land use types in Samarinda city. The results showed higher plastic levels near urban and agricultural areas, providing data on plastic pollution in a major Borneo river that local communities depend on.
