Microplastic contamination and risk assessment in the biotic and abiotic components of freshwater Manasbal Lake, western Himalaya, India

Microplastic contamination and risk assessment in the biotic and abiotic components of freshwater Manasbal Lake, western Himalaya, India
Researchers assessed microplastic contamination in both abiotic (water, sediment) and biotic (fish, invertebrates) components of Manasbal Lake in the western Himalaya, India, providing one of the first combined assessments of microplastic distribution in a remote mountain lake ecosystem. The study characterised microplastic abundance, morphology, and polymer types across compartments and conducted ecological risk assessments, finding measurable contamination despite the lake's remote location.

Co-occurrence of microplastics and heavy metals in a freshwater lake system in Indian Himalaya: Distribution and influencing factors
Researchers found widespread microplastic contamination in both the water and sediments of Manasbal Lake in the Indian Himalayas, with concentrations up to 4,020 particles per kilogram of sediment. Domestic sewage was identified as the primary source, and the microplastics were found alongside elevated levels of heavy metals like lead. This co-contamination is concerning because microplastics can absorb and transport heavy metals, potentially increasing toxic exposure for communities that depend on the lake.
Distribution and characteristics of microplastics and phthalate esters from a freshwater lake system in Lesser Himalayas
Researchers surveyed a freshwater lake system in the Indian Himalayas and found microplastics in all water and sediment samples, with concentrations highest near areas of human activity. They also detected phthalate esters, chemical additives commonly found in plastics, at levels that correlated with microplastic abundance. The study provides the first evidence of significant microplastic and associated chemical contamination in this relatively remote Himalayan freshwater ecosystem.
Microplastics in the high-altitude Himalayas: Assessment of microplastic contamination in freshwater lake sediments, Northwest Himalaya (India)
Researchers assessed microplastic contamination in sediments of freshwater Anchar Lake in the Kashmir Himalayas, finding an average of 606 particles per kilogram dominated by polyamide fibers, with domestic wastewater and textile sources identified as primary contributors.
Microplastic and heavy metal contamination in sediments of the high-altitude Nundkol Lake of northwestern Himalayas-Kashmir
Researchers found both heavy metals and microplastics in the sediment of a remote high-altitude glacial lake in the Himalayas, with microplastic levels averaging 76 particles per kilogram of dry sediment — predominantly plastic fibers from nylon. The contamination is likely linked to tourism, trekking, and fishing activities in what was once considered a pristine wilderness area.
Microplastic pollution in high-altitude Nainital lake, Uttarakhand, India
This is the first study to document microplastic contamination in Nainital Lake, a high-altitude lake in the Indian Himalayas that serves as the main drinking water source for the local town. Researchers found microplastics in every sample, with concentrations up to 56 particles per liter in lake water. Tourist activities and runoff were identified as the main pollution sources, raising concerns about drinking water safety for the local population.
First insights into plastic and microplastic occurrence in biotic and abiotic compartments, and snow from a high-mountain lake (Carnic Alps)
This study provided first data on plastic and microplastic occurrence in both biotic and abiotic samples from high-mountain lakes on the Tibetan Plateau, one of the most remote freshwater ecosystems on Earth. Plastics larger than 5 mm and microplastics were found in lake water and biota, demonstrating that even pristine high-altitude freshwater systems are not free from plastic contamination.
Identification, characterization, and quantification of microplastics in water and sediments of high-altitude Himalayan Dal Lake
Scientists found tiny plastic particles called microplastics in both the water and bottom sediments of Dal Lake, a high-altitude lake in the Himalayas. This discovery is concerning because it shows plastic pollution has reached even remote mountain areas, and these microscopic plastic pieces can enter our food chain through fish and drinking water. The findings suggest that microplastic contamination is more widespread than previously thought, potentially affecting water sources that communities depend on for drinking and fishing.
Microplastic contamination in environmental matrices of multi-basin Dal Lake, Kashmir
Researchers investigated microplastic contamination across water, sediment, and fish in Dal Lake, Kashmir, and found that sediments contained far higher concentrations than water or fish tissue. Polyethylene, polypropylene, and polystyrene were the most common plastic types identified, with finer sediment particles trapping more microplastics. Ecological risk assessments indicated moderate pollution levels, raising concerns about this popular freshwater ecosystem.
Pollution status of microplastics in the sediments of warm monomictic Dal lake, India: Abundance, composition, and risk assessment
Researchers conducted the first investigation of microplastic contamination in the sediments of Dal Lake in Jammu and Kashmir, India. They found concentrations ranging from 503 to over 3,000 particles per kilogram, with the highest levels occurring in spring, and identified multiple polymer types with polyester and polyethylene being most common. The study establishes baseline pollution data for this ecologically important lake and highlights the seasonal patterns of microplastic accumulation.
Lake sediments act as a sink of microplastics in the High-Altitude Himalayan Dal Lake, India
Researchers quantified microplastic concentrations in surface water and sediments of Dal Lake, a high-altitude Himalayan urban lake in India at 1,583 meters elevation, finding sediment concentrations up to nearly 13,000 particles per kilogram dry weight and concluding that lake sediments act as a long-term sink for microplastic accumulation.

This study investigated microplastic contamination in Kaptai Lake, the largest artificial lake in South Asia, and found concentrations ranging from 650 to 2,450 items per cubic meter in water and 135 to 607.5 items per kilogram in sediment. The majority of identified microplastics were small fibers less than 0.5 mm, with spatial variation influenced by polymer properties, local geography, and pollution sources.
Seasonal distribution of microplastics and associated ecological risks in a semi-arid freshwater ecosystem in India
Researchers measured microplastic contamination across seasons in a semi-arid lake in northwestern India and found significantly higher levels after the monsoon season compared to before. The most common plastics detected were polyethylene, polypropylene, and polystyrene, mostly in the form of fragments and fibers smaller than 500 micrometers. Risk assessments indicated that about 70% of the lake area faces very high ecological risk from microplastic pollution in both seasons.
