Microplastics Contamination in Water and Sediments: Seasonal and Spatial Distributions from the Urban Wetlands of Coimbatore, Tamilnadu, India
AI summary Read the abstract
Seasonal and spatial monitoring of three urban wetlands in Coimbatore, India found microplastic concentrations of 10–33 particles/L in surface water and 14–47 particles/0.5 kg in sediments, with monsoon season driving peak abundance and polyethylene terephthalate as the dominant polymer. Urban wetlands act as accumulation and transfer zones for microplastics, connecting city waste streams to aquatic biota and downstream human exposure.
Spatio-temporal variation of microplastics during the past four decades in a lacustrine sedimentary environment in southern India
AI summary Read the abstract
Using sediment dating techniques, researchers traced four decades of microplastic accumulation in a tropical Indian lake, finding a steady rise from 1975 to 2010 driven by rainfall, fishing, and poor waste disposal. This historical record demonstrates that microplastic pollution is not a recent phenomenon — it has been steadily building in freshwater systems for generations.
Assessing Microplastic Pollution in Indian Lake Ecosystems: A Mini Review
AI summary Read the abstract
This mini-review synthesizes findings from the 12 Indian lakes studied for microplastic contamination since the field's 2017 inception in the country, examining contamination levels, methodologies, and pollution sources across surface water, sediments, and biota. Freshwater lakes are critically understudied relative to marine environments, and the lack of standardized methods across studies makes cross-comparison difficult—limiting effective policy responses.
Microplastic in the Inland Water Ecosystem of India
AI summary Read the abstract
This review documented microplastic contamination in India's inland water systems — including rivers, lakes, reservoirs, and groundwater — identifying land-based pollution sources and assessing concentrations relative to international benchmarks. Inland freshwater contamination is particularly concerning because these systems supply drinking water and irrigation to hundreds of millions of people, creating direct human exposure routes.
