Characterization and Source Apportionment of Microplastic Contamination in Water Reservoirs: A Case Study in Ranchi, India
AI summary Read the abstract
This case study characterized microplastic contamination in water reservoirs in Ranchi, India, identifying polymer types, particle morphologies, and likely local sources of contamination. Reservoir studies in rapidly urbanizing regions illuminate how microplastics penetrate drinking water sources in lower-income settings where treatment infrastructure may be least equipped to remove them.
Microplastics (MPs) (≤5 mm) are ubiquitous in nature and have inhabited every sphere of our planet. Studies around the globe have focused on their impact on biological organisms and the environment. The world is thinking over ways to control these particles...

Morphology and Polymeric Composition-Based Source Apportionment of Microplastics in Surface Water and Sediment of Drinking Water Supply Reservoirs in Ranchi, India
AI summary Read the abstract
Researchers found high concentrations of microplastics — mostly PET and HDPE fragments, fibers, films, and foams — in drinking water supply reservoirs in Ranchi, India, with single-use and household plastics identified as major sources, raising serious concerns about microplastic contamination in tap water serving large urban populations.
Microplastics Pollution in the Reservoir: Occurrence, Extraction, and Characterization
AI summary Read the abstract
Researchers reviewed microplastic contamination in reservoirs — a major source of drinking water — examining how plastics enter and accumulate in these water bodies and what extraction and identification methods are most effective for monitoring plastic pollution at the water supply level.
Quantification and Characterization of Microplastics in Kanke Lake, a Freshwater System of Ranchi, Jharkhand, India
AI summary Read the abstract
Microplastic particles smaller than 5mm were found contaminating Kanke Lake, a freshwater system in Jharkhand, India, signaling degradation of water quality in a region where freshwater resources are already under pressure. The study underscores how emerging plastic contaminants are reaching inland water bodies that communities depend on for daily use.
Emerging Issue of Microplastic in Sediments and Surface Water in South Asia: A Review of Status, Research Needs, and Data Gaps
AI summary Read the abstract
Sediments and surface waters across South Asia show widespread microplastic contamination, yet significant data gaps and inconsistent monitoring methodologies limit a full understanding of pollution severity in the region. Standardized research frameworks are urgently needed to inform policy and protect populations dependent on these water sources.
Microplastic Pollution in Urban-Dal Lake, India: Uncovering Sources and Polymer Analysis for Effective Assessment
AI summary Read the abstract
A survey of 32 sediment sites in Dal Lake in the Himalayas found an average of 416 MP/kg dry sediment, dominated by nylon fibers (62.5%), with tourism, fishing, and untreated wastewater identified as primary sources. Microplastic contamination of a high-altitude Himalayan lake—a freshwater source for surrounding communities—demonstrates that MP pollution has reached even remote mountain ecosystems far from industrial centers.
