ClearMicroplastic contamination in Indian rural and urban lacustrine ecosystems
Researchers surveyed 39 rural and urban lakes across Tamil Nadu, India, for microplastic contamination and found particles present in water and sediment samples from every lake studied. Urban lakes had significantly higher microplastic concentrations than rural ones, with fibers being the most common particle shape across all sites. The study provides one of the most comprehensive assessments of freshwater microplastic pollution in India, revealing that even relatively remote lakes are not free from contamination.

Researchers conducted a preliminary study of microplastic pollution in two urban lakes in Bangalore, India—Bellandur and Madiwala—collecting water and sediment samples for analysis. Both lakes contained microplastics at measurable concentrations, with fibers and fragments most common, reflecting the heavy human activity and wastewater inputs in the surrounding urban areas.
A Critical Review on the Characterization and Distribution of Microplastic Contaminants in Indian Water Environments: Pathways and Related Hazards
This systematic review examines microplastic contamination in India's freshwater environments, including rivers and lakes. While marine ecosystems have gotten the most attention, freshwater sources — which supply drinking water — are also heavily contaminated. The findings highlight how inadequate waste management and recycling infrastructure allow microplastics to spread through the water systems that communities depend on.
Microplastic pollution – a rising threat along an urban lake in the Vellore district of Tamil Nadu, India: abundance and risk exposure
Researchers assessed microplastic pollution in Dharapadavedu Lake in Tamil Nadu, India, finding contamination in both water and sediment samples. Medium-sized microplastics (500-1,000 micrometers) were the most common, with polyethylene and polypropylene as the dominant plastic types. The study highlights the growing microplastic contamination in urban lake ecosystems that communities rely on, raising concerns about water quality and human exposure.

Researchers assessed microplastic pollution in lentic (still water) environments across India using material flow analysis and field data from 2011 to 2022. They found significant geographical variation in microplastic contamination across different Indian states, influenced by local waste management practices and population density. The study provides a framework for understanding how plastic waste flows contribute to microplastic accumulation in lakes and reservoirs.
