Identification and Characterization of Microplastics in Riverine Environment, Cauvery River (Mysore), Karnataka, India
Summary
Researchers identified and characterized microplastics in sediments of the Cauvery River, India, finding concentrations ranging from 40 to 150 items per kilogram with higher levels downstream of the KRS dam. FTIR spectroscopy confirmed the presence of PP, PET, PE, and Nylon polymers in various shapes and colors, highlighting the need for freshwater microplastic monitoring.
Microplastics (MPs) have received extensive attention as an emerging environmental pollutant. They are ubiquitous in the freshwater system and have triggered a global environmental concern. The MP contents in the Cauvery River sediments are inadequately understood due to a lack of quantification of sources, stores, and intermediates. In sediment samples concentration of MPs ranged from 40 ± 22 items kg”1 and 150 ± 56 items kg”1 in the upstream and downstream of KRS dam respectively, microplastics are found in various shapes, colours, and compositions, with red, dark brown, white, transparent. FTIR Spectroscopy analytical technique identified and analysed MP components (PP, PET, PE, and Nylon). The study emphasizes the importance of identifying and addressing microplastics in freshwater environments to mitigate their impact on aquatic ecosystems and inform policymakers.

Microplastic pollution in Kolavai Lake, Tamil Nadu, India: Quantification of plankton-sized microplastics in the surface water of lake
Researchers surveyed Kolavai Lake in Tamil Nadu, India, and found microplastics at an average of 6.1 particles per liter across the lake's surface water, with higher concentrations near urban and southern zones. The study used FTIR spectroscopy to confirm the chemical identity of particles and examined how microplastic abundance compares to zooplankton density, finding that microplastics were present at levels that could disrupt plankton feeding. These results highlight how even inland freshwater lakes in India are heavily contaminated, with implications for aquatic food chains and the communities that depend on this water.
