Microplastics in J&K’s Lakes and Rivers: From Mansar’s Sediments to Dal’s Food Fish

By: Anuj Kumar Verma

Recently, the researchers at MIT World Peace University, Pune, have detected microplastics in freshwater fish commonly consumed in the city, warning that plastic pollution is entering the human food chain through ordinary diets. The ongoing study by PhD scholar Simran Singh, supervised by Dr Soma Mishra, found fibres, fragments and pellets in fish samples and estimated that a person eating 250 grams of freshwater fish twice a week for 50 years could ingest between 93,600 and 124,800 microplastic particles. Health experts advise caution rather than panic: microplastics often concentrate in fish guts and gills rather than muscle, but repeated dietary exposure remains a potential concern because plastics can carry additives and adsorb toxic chemicals.
That warning is directly relevant to Jammu and Kashmir, a region whose environmental stresses are multiplying. Its fragile Himalayan ecology, limited carrying capacity, overutilisation of natural resources, unsustainable construction and road expansion, rising population, tourism dependent livelihoods, unmanageable city waste, growing everyday reliance on single-use plastics and irresponsible disposal practices are converging into a serious ecological crisis. Plastic pollution is only one symptom, but it is now visibly entering the region’s lakes, rivers and food chain.
Independent research has already detected microplastics in some of J&K’s most important freshwater systems.
In Dal Lake, a 2025 study published in the Journal of Contaminant Hydrology by Sajad Ahmad Rather, Adnan Amin, Adnan Abubakr, Monisa Mehboob Malik, Ifra Tabassum, Mohd Ashraf Rather, Mansoor Ahmad Rather, Bhagyashree Dhekale, Ishtiyaq Ahmad, Hafsa Farooq Chashoo, Udai Ram Gurjar and Caterina Faggio, as first incidence of microplastic in commercially important food fishes and waters: A case study in the dal Lake ecosystem of North-Western Himalaya (India)”
found microplastics in both lake water and the gastrointestinal tracts of commercially important food fish. The study recorded an average of 196.65 particles per litre in water and 3.66 to 22.33 particles per fish, with fibres, fragments and pellets among the forms detected.
Anchar Lake has also emerged as a microplastic sink. Research on its bottom sediments found an average of 606 microplastic particles per kilogram of dry sediment, with fibres making up 91 per cent of the particles. Polyamide, PET, polystyrene, PVC and polypropylene were identified, and the contamination was linked to human settlements, tourism-related litter, textile waste and packaging debris.
Wular Lake, a Ramsar-designated wetland, shows a similar pattern. Microplastic Pollution in Wular Lake, Kashmir-India (Ramsar Site): First Report and Associated Risk Assessments, published in March 2026, investigates microplastic contamination and its associated ecological risks in the sediments of Wular Lake, Kashmir—a Ramsar-designated site. Sediment samples collected from 32 locations were analyzed for microplastic abundance, composition, and pollution hazard. Microplastics were present at all sites, with concentrations ranging from 300 to 1,280 particles per kilogram of dry sediment (p/kg dw) and a mean of 835.6 p/kg dw. Hotspots exceeding 1,000 p/kg dw included sites WL19, WL5, WL2, WL10, and WL20, with the northeastern region being the most contaminated. Fibres made up 74.7 per cent of the particles, and nylon or polyamide was the dominant polymer.
Mansar Lake provides further evidence that plastic particles have reached Jammu-region waters. A 2026 study in Environmental Science: Advances by Kumar Ajay, Nafees Ahmad, Sunil Kumar, Aayush, Praveen K Mishra and Ambili Anoop, affiliated with IISER Mohali, IIT Roorkee and Cluster University Jammu, was published wherein it was reported:
In Mansar Lake, an anthropogenically influenced and unregulated site, exhibited substantially higher microplastic levels, varying between 45–120 particles per L in the water and 390–5720 particles per kg in the sediment. In contrast, Sukhna Lake, which is relatively well managed, microplastic concentrations ranged from 5–75 particles per L in the surface water and 170–2320 particles per kg in the sediment. The researchers linked the high levels of contamination in Mansar lake to tourism, boating, sewage, temple waste, agriculture and catchment runoff.
The Jhelum River offers the clearest evidence of how unmanaged waste turns into microplastic pollution. A 2023 study titled as “Abundance and characteristics of microplastics in a freshwater river in northwestern Himalayas, India – Scenario of riverbank solid waste disposal sites” by NIT Srinagar researchers including Muneeb Farooq, Farhat Un Nisa, Zahoor Manzoor, Sachin Tripathi, Adhithiya Venkatachalapati Thulasiraman, Mohammad Imran Khan, Mohd Yawar Ali Khan and Khalid Muzamil Gani, found microplastics at every sampling site along the river. The average concentration was 1,474 particles per cubic metre, with a range of 600 to 2,500 particles per cubic metre.
The study found that microplastic concentrations increased threefold downstream of unscientific municipal solid-waste disposal sites compared with upstream stretches. Polyethylene was the most common polymer, followed by PVC and polypropylene; flakes were the dominant form, followed by filaments, fragments and spherules. Co-author Muneeb Farooq said unscientific municipal solid-waste disposal sites were a potential source of microplastic pollution along the Jhelum and described the results as alarming.
The researchers’ central remedial message was timely and scientific municipal solid-waste management. They warned that land-based pollution sources must be addressed urgently, particularly because Srinagar’s Achan dumpsite receives an estimated 400 to 500 tonnes of city waste daily and because this waste in peri-urban and rural areas often ends up on Jhelum riverbanks. The study also pointed to the need to remediate J&K’s legacy dumpsites, which then held an estimated 1.9 million tonnes of old waste, of which only about 12 per cent had been treated.
Surinsar Lake, Mansar’s twin lake, has been reported to face deteriorating water quality due to human interference, but detailed peer-reviewed microplastic data for the lake remain limited. The same is true of the Tawi, Suran and the rivers draining Poonch and Rajouri. Their absence from the microplastic literature should not be mistaken for clean water; these water bodies urgently need baseline monitoring of water, sediment, fish and riverbank waste.
In a study titled “Unravelling land-based discharge of microplastics in River Basantar of Jammu & Kashmir, India: Understanding sinking behaviors and risk assessments”
by Shaveta Padha, Rakesh Kumar, Yogesh Sharma and Anjali Dhar, affiliated with Central University of Jammu and Auburn University, it was found that 200 to 850 microplastic particles were found per litre in surface water and 1 to 6 particles per gram in sediment. Their 2025 study in the Journal of Contaminant Hydrology identified fragments, fibres and films, and associated the pollution with urbanisation, industrial discharge, household waste and agricultural runoff.
Central University of Jammu researchers Anshika Sharma and Priti Kumari, supervised by Prof. Deepak Pathania and Prof. Richa Kothari, have reported microplastics in the Ujh River in Kathua and the Chenab in Kishtwar. In the Ujh, microplastics were reportedly found in every water, sediment and fish sample examined, with 280 particles recovered from water and 75 from sediment; in the Chenab study, 20 particles were found in fish, including the gastrointestinal tract, gills and liver.
The Ravi, which rises in the Himalayan region, has also been found contaminated in water, air and sediment in downstream research, with PET, polyisobutylene and polychloroprene among the polymers detected. Synthetic textiles and domestic sewage were identified as likely sources. For the Tawi, Suran, Poonch and Rajouri rivers, the absence of comparable published microplastic studies is itself a governance gap: they require urgent scientific assessment rather than assumptions of safety.
The health concern for local populations is not that every fish is immediately dangerous, but that contamination is persistent and preventable. Microplastics are often concentrated in fish guts and gills, so whole-fish consumption, small fish and poorly cleaned fish may carry greater exposure risk. Studies have associated microplastic exposure in fish with gut damage, inflammation, oxidative stress and immune or physiological effects, while plastics can carry additives and adsorb toxic chemicals from water.
The government must act on the source of the problem: unmanaged city waste. J&K generates about 1,557 tonnes of municipal solid waste daily but processes only about 1,027 tonnes, leaving a daily treatment gap of roughly 530 tonnes, according to figures placed before the National Green Tribunal and the J&K Legislative Assembly. Srinagar generates about 550 tonnes daily but processes only about 210 tonnes, while Jammu collects about 375 tonnes daily and processes about 295 tonnes; together, the two cities are processing only about half of the waste they handle.
This untreated waste is where microplastics begin. Thin polythene bags, wrappers, pouches, cigarette-packet films, sweet-box linings and discarded plastic water bottles can fragment in sunlight and floodwater; when dumped outside municipal areas or thrown along nallahs, lake shores and riverbanks, they can be carried into Dal, Anchar, Wular, Mansar, the Jhelum, Basantar, Ujh and other water bodies. The Jhelum study found that concentrations rose threefold downstream of dumping sites, making the link between poor waste management and freshwater contamination explicit.
Following the remedial direction suggested by the NIT Srinagar researchers, the government should prioritise scientific waste management: end open dumping beside rivers, remediate legacy dumpsites such as Achan, expand segregated collection and material-recovery facilities, and ensure that bulk waste generators comply with segregation and processing rules.
The government should also impose a strict restriction on packaged drinking water in plastic bottles up to one litre in government offices, tourist sites, hotels, restaurants and public events, and replace it with purified water fountains and water ATMs at bus stands, hospitals, markets, educational institutions and tourist destinations. These facilities must undergo regular water-quality testing and maintenance so that they offer a safe, credible alternative to bottled water.
It should also ban or replace polythene films used to wrap cigarette packets and line sweet boxes, and enforce the existing prohibition on polythene bags below 120 microns in busy markets, weekly bazaars, fruit and vegetable mandis, tourist spots and riverbank settlements. Enforcement must target manufacturers, wholesalers, shopkeepers and bulk waste generators, not merely consumers. Public campaigns should encourage people to carry reusable steel, glass or earthen bottles, while hotels, restaurants and event organisers should provide refill facilities rather than single-use plastic bottles.
Microplastics in Dal, Anchar, Wular, Mansar, the Jhelum, Basantar, Ujh and Chenab show that J&K’s freshwater systems are already carrying the consequences of careless plastic use. If the government waits until microplastics are routinely found in every fish sold in local markets, it will be responding to a crisis that has been visible for years in choked drains, plastic-lined riverbanks and unmanaged municipal waste. The time to act is now, through strict waste enforcement, reduced single-use plastics, remediation of legacy dumpsites, safe public drinking-water alternatives like purified water fountains, water ATMs and independent monitoring of the region’s lakes, rivers and food fish.
