ClearCorrelation of Microplastic Size Distribution and Water Quality Parameters in the Upstream Brantas River
Researchers surveyed microplastic abundance and size distribution in the upstream Brantas River in Indonesia and analyzed correlations with water quality parameters, finding that smaller microplastic fragments were most prevalent and that microplastic levels related to several water quality indicators. The study contributes baseline data for managing plastic pollution in Indonesian river systems.

This paper is not about microplastics; it uses water quality indices and statistical analysis to assess pollution in the Brunei River from urban, agricultural, and industrial runoff.
Identifying the distribution and source of riverine plastic waste contamination: case study of Brantas River in Malang city
Researchers investigated microplastic concentrations and macroinvertebrate communities at three stations along the Brantas River in Malang City, Indonesia, integrating microplastic counts, SIGNAL-2 bioassessment scores, and household waste management surveys. The highest microplastic burden and lowest macroinvertebrate diversity occurred at the station where 80% of residents disposed of plastic waste directly into the river.
Assessment of stream quality and health risks in Indonesian river systems: A social analysis and water quality index approach
Researchers assessed water quality in three Indonesian rivers used by local communities, finding microplastics — primarily polyethylene and polypropylene — alongside elevated levels of iron, lead, and manganese, with residents reporting rising rates of skin disease and diarrhea linked to polluted water use.
Analysis of Microplastic Contamination on Water and Sediment in the Brantas Subwatershed of the Malang Area
This Indonesian study (published in Bahasa Indonesia) analyzed microplastic contamination in both water and sediment of the Brantas River sub-watershed in the Malang area, one of the most important river systems in East Java. Microplastics were found in both water and sediment samples across sampling locations, with fibers being a dominant form. The Brantas River supports millions of people for drinking water and irrigation, making evidence of microplastic contamination in this system a significant public health and environmental concern.
Assessing land-use impacts on a 5th-order tropical river using multiple environmental indicators
Researchers combined multiple environmental indicators to assess the health of a tropical river system in Brazil affected by land-use change from agriculture and urbanization. Rivers in degraded landscapes also carry higher microplastic loads, and multi-indicator approaches provide a more complete picture of ecosystem health.
Analysis of microplastic abundance in Brantas river, East Java
Researchers measured microplastic abundance at three stations along the Brantas River in East Java — upstream (Batu City), midstream (Nganjuk), and downstream (Sidoarjo) — finding concentrations ranging from 0.66 to 0.88 particles/L, with the highest levels downstream. Water quality parameters remained within Indonesian regulatory standards, but the findings highlight microplastic accumulation in a major drinking water source.
Identification of Microplastics in Water and Fish in the Brantas River, Malang City
This study identified microplastics in both water and fish tissues in the Brantas River in Malang City, Indonesia, with FTIR analysis confirming multiple polymer types, establishing baseline contamination data for this densely populated watershed. The presence of microplastics in fish is a direct human health concern given that river fish are a common protein source for local communities.
Identifikasi Mikroplastik Pada Air, Sedimen, dan Bivalvia di Hilir Sungai Brantas
This Indonesian study identified microplastics in water, sediment, and bivalves in the lower Brantas River. Plastic fragments and fibers were found across all sample types, raising food safety concerns since local communities consume shellfish from this waterway.
Water Pollution Index and Microplastic Ecological Risk in The North Coastal Area of Situbondo
Researchers assessed water quality and microplastic ecological risk across 15 locations along the northern coast of Situbondo, Indonesia, and found mild water pollution throughout the study area. Microplastics were found at all sampling sites, with industrial-adjacent areas and estuaries showing higher ecological risk than natural river locations. The study provides baseline data on the extent of microplastic contamination in an Indonesian coastal region and highlights the need for monitoring near industrial zones.
Seasonal Variation Analysis of Microplastic Distribution in the Estuary of Brantas River
Microplastic abundance in the Brantas River estuary in Surabaya, Indonesia, varied with the seasons, rising during rainy periods when increased runoff carries more plastic debris from land into the waterway. Because Brantas River water is used for drinking water supply and irrigation, understanding seasonal peaks in microplastic loading is critical for managing exposure risks for both humans and agricultural ecosystems.
Assessment of Bango River Water Quality on Different Land Uses
Researchers assessed water quality in the Bango River in Indonesia across different land uses, finding that agricultural, residential, and industrial activities each contributed distinct pollution patterns affecting physicochemical parameters and overall river health.
A Spatial Model of Microplastic Pollution Mitigation as an Effort to Preserve the Brantas River Ecosystem
This paper presented a spatial model of microplastic pollution mitigation strategies in an Indonesian coastal area, mapping pollution sources and evaluating the effectiveness of different intervention locations. The spatial approach identified high-priority intervention sites for protecting marine habitats.
Correlation Analysis of Water Quality and Microplastic Identification in the North Coast Area of Situbondo
Researchers assessed water quality and identified microplastics in a river in North Kalimantan, Indonesia, finding correlations between water quality parameters and microplastic abundance and characterizing the dominant polymer types and morphologies present.
Temporal Variation of Microplastic Abundances and Characteristics in Surface Water of Banger River of Pekalongan City, Indonesia
A time-series study of the Banger River in Pekalongan, Indonesia — an industrial batik textile hub — found microplastics throughout the river system with varying abundances across sampling periods. The findings confirm that textile industry discharge is a major source of river microplastic contamination, which ultimately flows into coastal waters and the food chain.

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.
