Microplastics in Selected River Waters: Experimental Screening, Environmental Transport, and Potential Human-health Implications of Plastic-associated Additives
AI summary Read the abstract
Researchers tested water from nine rivers in India for microplastics and related water-quality measures. Levels of the microplastic measurement varied by site and were strongly linked to other factors like electrical conductivity, dissolved solids, hardness, and chloride content.
Microplastics (MPs) are increasingly recognized as persistent contaminants capable of moving through river networks, partitioning between the water column and sediments, and interacting with dissolved and particulate contaminants.This study presents a screening-level experimental assessment of nine river-water samples collected from Netta, Kazhiyal, Thirparappu, Vazhaithottam/Arumanai, Thikkurichi, Mathoor, Kuzhithurai, ST Mangad, and Parakani/Thengapattanam.The supplied laboratory reports document 1000-mL water samples collected by hand between 10 and 14 December 2025 and analyzed for physicochemical parameters and a laboratoryreported "Micro Plastics" parameter using ISO/TR 21960:2020.The reported microplastic parameter ranged from 0.6 to 1.5 in the laboratory's stated units (NTU), with the highest value at Parakani/Thengapattanam and elevated values at ST Mangad and Kuzhithurai.Across the nine sites, mean pH was 6.71, electrical conductivity 173.3 µS/cm, total dissolved solids 53.2 mg/L, turbidity 4.27 NTU, and the reported microplastic parameter 0.92.Exploratory Pearson analysis showed strong positive associations between the reported microplastic parameter and electrical conductivity (r=0.93),total dissolved solids (r=0.92),hardness (r=0.92),chloride (r=0.91), and Microplastics in Selected River Waters: Experimental Screening, Environmental Transport, and Potential Human-Health Implications of Plastic-Associated Additives https://iaeme.com/Home/journal/IJARB11

Microplastics as a contaminant in Indian riverine system: a review
AI summary Read the abstract
This systematic review examines microplastic contamination across India's river systems, documenting the types, sources, and concentrations of plastic particles found in major waterways. The findings are concerning for human health because these rivers provide drinking water and irrigation for hundreds of millions of people, creating widespread potential exposure to microplastics.
