This is a dataset, not a research article. It contains microplastic measurements from water, sediment and groundwater at seven sites along a river-canal system in India, collected across three seasons, including particle counts, plastic types, sizes, and risk calculations.
This dataset supports the study “Seasonal patterns of microplastic transfer, sediment retention and groundwater-associated fiber enrichment in an Upper Ganga River–canal corridor.” It contains microplastic abundance and characterisation data for surface water, sediment and groundwater-associated samples from seven sampling stations (L1–L7), covering summer, winter and monsoon campaigns. The dataset comprises 17 tables containing replicate-level abundance measurements, corresponding means and standard deviations, polymer composition, particle size, shape and colour distributions, and seasonal contributions of dark-coloured particles. Microplastic abundance is expressed as particles L⁻¹ for surface-water and groundwater-associated samples and particles kg⁻¹ dry weight for sediment. Polymer composition is reported by matrix and campaign for spectroscopically confirmed particles, using a spectral-library match threshold of at least 75% together with manual verification of diagnostic bands. Derived assessment tables include contamination factors calculated using matrix-specific internal reference concentrations, polymer-specific contributions to the Polymer Hazard Index (PHI), and station- and season-specific Potential Ecological Risk Index (PERI) values and classifications. Statistical summaries include one-way ANOVA and Kruskal–Wallis tests, alongside principal component analysis variance explained, group scores and qualitative loading patterns. The data support comparisons of seasonal and spatial microplastic abundance, particle characteristics across environmental matrices, sediment-associated retention patterns and groundwater-associated fibre enrichment. The accompanying table notes document measurement units, calculation equations, reference concentrations, polymer hazard scores and risk classification thresholds. The dataset is provided as an OpenDocument Text (.odt) file.

This is a dataset, not a study with new findings. It provides measurements of tiny plastic particles found in river water, sediment and groundwater at seven sites along an Indian river-canal system, across three seasons, including particle types, sizes, colors and risk calculations.

Sediment and surface water microplastic contamination along the Ganges River, from the Himalayan foothills to the tidal reach downstream of Kolkata, India.

Researchers assessed microplastic contamination along the full length of the Ganges River from the Himalayan foothills to the tidal reach downstream of Kolkata, India, finding particles throughout the catchment at varying concentrations. The study is one of the first comprehensive surveys of microplastics along this major river system, which is estimated to be one of the world's largest ocean plastic sources.
Microplastics pollution in inland aquatic ecosystems of India with a global perspective on sources, composition, and spatial distribution
AI summary Read the abstract
Researchers reviewed microplastic contamination in India's rivers, lakes, and wetlands, finding widespread pollution across water, sediment, and wildlife, with concentrations peaking during monsoon season due to runoff. The review highlights a critical gap: most studies don't account for how water flow and seasonal variation affect where microplastics go, making it hard to gauge the true health risk to people and ecosystems.
Geospatial analysis and environmental risk assessment of microplastic (MP) pollution in hydro-environment of the Morwa River Catchment area, Uttar Pradesh, India
AI summary Read the abstract
Scientists studying a river system in India found tiny plastic particles (mostly a common plastic called polyethylene) not just in surface water, but also in groundwater—the water source many people rely on for drinking. This matters because groundwater is often assumed to be naturally filtered and safe, so finding microplastics there suggests our drinking water sources may be more vulnerable to plastic contamination than we thought. The researchers also suggest safer, biodegradable plastic alternatives that could help reduce this kind of pollution going forward.
