ClearMicroplastic Pollution in Urban Lake Phewa, Nepal: The First Report on Abundance and Composition in Surface Water of Lake in Different Seasons
Researchers conducted the first survey of microplastics in Lake Phewa, a major freshwater lake in Nepal, finding plastic particles in surface water across all seasons. Fiber microplastics were most abundant, consistent with laundry and textile sources. This study provides baseline data for microplastic monitoring in Nepal, where freshwater microplastic research has been largely absent.

Microplastics in freshwater lakes: A case study from Southern India
Researchers assessed microplastic contamination in Vellayani Lake, a major drinking water source in southern India, and found particles present across all sampling sites and seasons. Fibers were the most common shape, with polyethylene and polypropylene as the dominant polymer types, likely originating from domestic wastewater and fishing activities. The study highlights the need for monitoring microplastic pollution in freshwater lakes that serve as critical drinking water supplies.
Assessment of Microplastics in Hanumante River of Kathmandu Valley
Researchers found 14–23 microplastic particles per liter in water samples from the Hanumante River in Nepal's Kathmandu Valley, with polyethylene, polypropylene, and polycarbonate identified as the dominant polymer types. The contamination reflects poor plastic waste management in the surrounding communities, as the river receives untreated runoff and waste. The study underscores the need for improved waste infrastructure in rapidly urbanizing South Asian cities to prevent rivers from becoming conduits for microplastic pollution.

This study compared microplastic contamination in two Philippine lakes with different human-use profiles — one used for ecotourism and one more urbanised — finding microplastic particles in both, with characteristics reflecting local pollution sources. The results underscore that freshwater lakes, even smaller and less-studied ones, are not spared from microplastic pollution and warrant greater monitoring attention.
