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.
