Preliminary studies on the microplastic pollution in Dal lake, Kashmir (first report)
AI summary Read the abstract
This study provides the first documented detection of microplastics in Dal Lake in Kashmir, India. Researchers found microplastics at all four sampling stations in surface water, with fibers and fragments being the most common types. The findings establish baseline contamination data for a culturally important and ecologically sensitive high-altitude lake.
We provide the first study on the occurrence of microplastics in Dal lake, Kashmir, India. Microplastics act as catastrophe that trigger many environmental problems. The key origins of microplastics are larger plastics, which split into smaller plastics after UV light disintegration. There is relatively little work carried out on the existence of microplastics. The present work has been undertaken on the occurrence of microplastics at four pre-selected sites (surface water) in Dal lake, Kashmir. The samples were taken to the laboratory to dissolve organic matter by using H2O2 (6%). To speed up the organic digestion; the treated mixture was heated on a hot plate at 70

Pollution status of microplastics in the sediments of warm monomictic Dal lake, India: Abundance, composition, and risk assessment
AI summary Read the abstract
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.
Identification, characterization, and quantification of microplastics in water and sediments of high-altitude Himalayan Dal Lake
AI summary Read the abstract
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.

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 contamination in environmental matrices of multi-basin Dal Lake, Kashmir
AI summary Read the abstract
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.
First incidence of microplastic in commercially important food fishes and waters: A case study in the dal Lake ecosystem of North-Western Himalaya (India)
AI summary Read the abstract
Researchers found microplastics for the first time in commercially important fish and water from Dal Lake in India's Himalayas, with water containing about 197 particles per liter and fish harboring up to 22 particles each. Polyethylene was the most common plastic type found, and the presence of microplastics in food fish indicates these particles are moving up the food chain toward human consumers.
