Assessment of Microplastics in the Surface Water of Mengkabong and Salut Rivers of Sabah, Malaysia
Researchers conducted the first study of microplastic pollution in rivers in Sabah, Malaysia, finding microplastics at every sampling location. The Salut River had significantly higher concentrations than the Mengkabong River, with fibers being the dominant shape, likely originating from textile washing, fishing, and aquaculture activities. The study provides important baseline data on microplastic contamination in a region where such pollution had not previously been documented.

Microplastic concentrations in river water and bed sediments in a tropical river: implications for water quality monitoring
Researchers found that microplastic concentrations in a tropical Malaysian river averaged 3.12 particles/L in water and 6,027 particles/m² in bed sediments, with high within-site variability and poor correlation between water and sediment contamination levels, complicating monitoring strategies.
Abundance and Distribution of Microplastics in the Water and Riverbank Sediment in Malaysia – A Review
Microplastic abundance and distribution were surveyed in the water column and riverbank sediments of a Malaysian river. Results showed microplastics throughout the river system, with fiber shapes dominating in water and fragments more common in sediments, reflecting contributions from domestic wastewater and plastic litter.
Microplastics in Malaysia's Aquatic Environment: Current Overview and Future Perspectives
This review summarizes microplastic research across Malaysia's rivers, coastal waters, seafood, and sediments, finding widespread contamination in all aquatic environments studied. Fibers and fragments from everyday plastic products were the most common types found. The authors highlight that Malaysians face significant microplastic exposure through seafood consumption and call for better pollution monitoring and waste management policies.
Microplastics analysis in Malaysian marine waters: A field study of Kuala Nerus and Kuantan
Researchers conducted the first detection of microplastics in Malaysian marine waters at Kuala Nerus and Kuantan, identifying plastic types and concentrations in surface waters from two sites representing different levels of anthropogenic activity.
Microplastic Contamination and Ecological Risk Assessment in Tropical Riverine Surface Water of Selangor River Basin, Malaysia
Researchers analyzed microplastic abundance and risk in the Selangor River Basin in Malaysia, collecting surface water from 25 sites and detecting 361 particles with an average density of 1.44 particles per liter. Stereomicroscopy and FTIR confirmed the presence of multiple polymer types across upstream, tributary, and downstream zones.
Microplastic contamination in water, sediment, and fish from the Kahayan River, Indonesia
Researchers assessed microplastic contamination in water, sediment, and fish from the Kahayan River in Central Kalimantan, Indonesia. They found microplastics present across all sample types, with fibers and fragments being the most common forms, and identified polyethylene and polypropylene as the dominant polymer types. The study provides the first baseline data on microplastic pollution in this region and highlights the widespread nature of contamination in Indonesian freshwater systems.
Abundance and distribution of microplastics in tropical estuarine mangrove areas around Penang, Malaysia
This study documented microplastic pollution in tropical mangrove estuaries around Penang, Malaysia, finding thousands of plastic particles in both water and sediment samples. Concentrations were particularly high near the more urbanized Seberang Perai area, where sediment contained up to 4,000 particles per kilogram. The research highlights that tropical mangroves, which serve as important nursery habitats for marine life, are accumulating significant amounts of microplastic pollution.
Estimation of macroplastic yield from river basin to coastal area: A case study of the Klang River, Malaysia
Researchers studied macroplastic distribution along a 20-kilometer stretch of the highly polluted Klang River in Malaysia and developed a method to estimate total plastic yield from the river basin to the coast. They found 240 items of weathered macroplastics and characterized their composition and degradation patterns. The study provides a practical protocol for quantifying how much plastic pollution flows from rivers into coastal marine environments.
