This first-ever study of microplastics in Harike Wetland, India's largest northern wetland and a Ramsar-designated protected site, found plastic particles throughout the water and sediment. The contamination of this internationally recognized conservation area highlights that even protected freshwater ecosystems are not shielded from microplastic pollution.
Microplastic contamination in Ashtamudi Lake, India: Insights from a Ramsar wetland
Researchers investigated microplastic contamination in water, sediment, fish, and shellfish of Ashtamudi Lake, a Ramsar-designated wetland in southwest India. They found microplastics present across all sampled compartments of this ecologically and economically important brackish water system. The study raises concerns about potential human exposure to microplastics through locally consumed fishery resources from this important coastal lake.
Water quality degradation and eutrophication risk in the Ashtamudi wetland: role of physicochemical factors and microplastics
Researchers assessed water quality and microplastic distribution across seven sites in the Ashtamudi coastal wetland in India, a Ramsar-designated site, finding significant spatial heterogeneity in both physicochemical parameters and microplastic contamination and evaluating eutrophication risk.
Assessment of surface water dynamics through satellite mapping with Google Earth Engine and Sentinel-2 data in Manipur, India
Researchers used Google Earth Engine and Sentinel-2 satellite imagery to map seasonal surface water dynamics in Manipur, India, accurately tracking the extent and timing of water body changes across the region to support watershed planning.
Transitioning Wintering Shorebirds to Agroecosystem: A Thorough Evaluation of Habitat Selection and Conservation Concern
This study evaluated habitat selection by wintering shorebirds in agroecosystems following natural wetland degradation in the Indian subcontinent, finding that some species have transitioned to using agricultural lands. The authors discuss conservation implications for shorebird populations relying on altered habitats along the Central Asian Flyway.
Distribution of microplastics in the catchment region of Pallikaranai marshland, a Ramsar site in Chennai, India
Researchers analyzed microplastic distribution in surface water and sediments of the Pallikaranai marshland, a Ramsar-designated wetland in Chennai, India, finding significant contamination in this ecologically sensitive freshwater ecosystem that serves as an important urban biodiversity hotspot.
[Pollution Characteristics of Microplastics in Migratory Bird Habitats Located Within Poyang Lake Wetlands].
Researchers found microplastics in surface water, sediment, and the droppings of migratory birds at a Chinese wetland lake, raising concerns about how birds can transport microplastics across long distances. The study suggests that migratory birds may be spreading plastic contamination between distant habitats.
Impacts of Land Use Change on Water Quality Index in the Upper Ganges River near Haridwar, Uttarakhand: A GIS-Based Analysis
Researchers assessed water quality in the upper Ganges River near Haridwar using GIS-based analysis, finding that land use changes including urbanization and agriculture significantly impacted water quality parameters along a 78-kilometer stretch.
The measurement of microplastics in surface water and their impact on histopathological structures in wading birds of district Lahore
Researchers measured microplastic pollution in surface water around Lahore, Pakistan, and examined its effects on local wading birds. The Ravi River had the highest contamination, with over 5,000 particles per cubic meter, and birds living near these waters showed tissue damage in multiple organs. This study demonstrates that microplastic pollution in urban waterways can harm wildlife and may indicate broader risks for communities relying on these water sources.
Spatiotemporal microplastic occurrence study of Harike wetland, A Ramsar wetland of India
Researchers conducted a spatiotemporal study of microplastic contamination in Harike wetland, India's largest Ramsar wetland, examining water, canal sediment, and gut contents of Cyprinus carpio fish using ATR-FTIR and GC-MS. They found HDPE and nylon as the dominant polymer types, seasonal variation with higher concentrations in winter, and a 7% microplastic recovery rate from fish gut contents, highlighting contamination in this internationally protected ecosystem.
Non-Invasive Assessment of Microplastic Contamination in the Avian Biodiversity of Gharana Wetland, Jammu and Kashmir

The findings raise concerns about microplastic exposure in both native and migratory birds at this protected Important Bird Area.
Variations of surface water quality in selected tidal creeks of Sagar Island, Indian Sundarban eco-region: a multivariate approach
Researchers monitored water quality in tidal creeks of India's Sundarbans mangrove region for a full year, finding that salinity, turbidity, and dissolved oxygen varied most dramatically across seasons and were heavily influenced by monsoon runoff and boat traffic. The baseline data provides a foundation for managing water quality in this ecologically sensitive and biologically rich estuary.
Shorebird droppings analysis: Microplastics and heavy metals in a key conservation reserve and adjoining sand beaches in the west coast of India
Researchers analyzed droppings from ten migratory shorebird species at a conservation reserve on India's west coast and found microplastics and heavy metals in samples from all species. The contamination levels varied by species and season, reflecting differences in diet and habitat use. Since shorebirds are top predators in coastal food webs, their contamination indicates widespread microplastic and heavy metal pollution throughout the coastal ecosystem.
Application of pressure–state–response approach for developing criteria and indicators of ecological health assessment of wetlands: a multi-temporal study in Ichhamati floodplains, India
Researchers developed and tested a comprehensive 105-indicator framework for assessing the ecological health of tropical floodplain wetlands in eastern India, applying it across seven sites over multiple years. The results showed that agriculture-dominated wetlands were the most degraded, while fishing-dominated wetlands fared better, offering a replicable tool for wetland management in similar regions.

First Evidence of Microplastics' Presence in Surface Water and Fishes of Bhoj Wetland (Ramsar Site).
Scientists found tiny plastic particles called microplastics in the water and fish of a wetland in India, with higher levels during dry seasons when there's less water to dilute pollution from sewage and tourism. The fish that people commonly eat contained these plastic pieces in their bodies, mostly from broken-down fishing gear and plastic trash. This matters because when we eat contaminated fish, we might also be consuming these microplastics, though more research is needed to understand the full health effects.
