Food & water under threat from microplastics in fields, rivers across Telangana, Andhra Pradesh
Hyderabad: Microplastics are emerging as a silent threat in landfills in Hyderabad, Godavari river and agricultural land across Telangana and Andhra Pradesh.
Recent scientific research has identified alarming levels of microplastics in Godavari and associated water bodies in Telangana and AP.
A study published in the Journal of Environmental Management in 2025 examined surface water and water treatment plants in West Godavari.
It found 330 microplastics (MPs) particles in river surface water from 15 samples and 121 MPs in six samples in water treatment plant.
These MPs, primarily composed of blue and transparent fibres smaller than 500 micrometres (µm), were traced to commonly used plastic polymers, including polypropylene, polyvinyl chloride (PVC), polycarbonate, nylon, and polyethene terephthalate (PET).
Larger MPs exceeding 3,000 µm were observed in treated water.
Risk indices used in the study, including the Pollution Load Index and Ecological Risk Index, suggested that the type of polymer, rather than quantity, posed significant environmental risks. Researchers said India generates 9.3 million tonnes of plastic annually, accounting for over 20% of global plastic pollution due to poor waste management. They suggested the need for improved control around urban run-off and water treatment protocols to address its menace in rivers.
Soil Contamination Through Irrigation And Landfills
The ecological threat is not limited to rivers. Another review titled 'Microplastic Contamination in Agricultural Soils Across India: A Systematic Review of Studies and Research Gaps' analysed data from 73 studies conducted between 2020 and 2024. It revealed significant risks of microplastic infiltration into soil across India, particularly in Telangana and AP.
In Hyderabad, fields near Jawahar Nagar landfill are at risk due to leachate infiltration into underground water. These pollutants can enter irrigation networks and eventually accumulate in fields. This finding is supported by a separate 2023 study titled 'Preliminary Evidence of Microplastics in Landfill Leachate, Hyderabad, India' (Process Safety and Environmental Protection journal).
The use of polluted water for irrigation, plastic mulch in farming, and improper waste management are major contributors to soil microplastic contamination.
In AP, land irrigated with water from Godavari, which is already confirmed to contain MPs, face similar risks. Northern coastal regions are especially vulnerable due to atmospheric deposition and run-off from contaminated beach sediments.
Gaps In Southern India's Research On Plasticulture And Wastewater Irrigation
While plastic-based farming such as mulching and drip irrigation are widespread in Telangana and AP, their contribution to soil microplastic level is poorly studied.
Additionally, peri-urban agriculture in cities such as Hyderabad often uses treated and untreated municipal wastewater, yet few studies assessed the MP levels.
Moreover, there is no clear understanding of how microplastics interact with specific soil types found in the region. There are also no studies assessing microplastic uptake in major southern crops such as rice, pulses and millets, raising worries about food safety and long-term soil health. The existing evidence highlights an urgent need for policy intervention, localised scientific research and enhanced waste and water management to curb the spread of microplastics.

Glitter's Sparkle Hides A Darker Side - It Can Change The Chemistry Of Our Oceans
Glitter is festive and fun – a favourite for decorations, makeup and art projects. But while it may look harmless, beautiful even, glitter's sparkle hides a darker side. Those shimmering specks often end up far from party tables and greeting cards. You can even spot them glinting on beaches, washed in with the tide. In our recent research, we discovered that glitter – specifically, the kind made from a common plastic polymer called polyethylene terephthalate (PET) – is not merely polluting the ocean. It could actively interfere with marine life as it forms shells and skeletons, which is a much bigger deal than it might sound. Put simply: glitter helps the formation of crystals that nature did not plan for. And those crystals can break the glitter into even smaller pieces, making the pollution problem worse and more long-lasting. We tend to think of microplastics as tiny beads from face scrubs or fibres from clothes, but glitter is in its own special category. It is often made of layered plastic film with metal coatings – the same stuff found in craft supplies, cosmetics, party decorations and clothing. It is shiny, colourful and durable – and extremely tiny. That makes it hard to clean up and easy for marine animals to eat, because it looks tasty. However, our research paper in the journal Environmental Sciences Europe suggests that what really sets glitter apart from other microplastics is the way it behaves once it enters the ocean. It actively interacts with its surroundings; it's not drifting passively. In our lab, we recreated seawater conditions and added glitter to the mix to explore whether glitter would affect how minerals – like the ones marine animals use to make their shells – form. What we saw was surprisingly fast and incredibly consistent: the glitter was kickstarting the formation of minerals such as calcite, aragonite and other types of calcium carbonates in a process known as 'biomineralisation'. These minerals are the building blocks that many marine creatures – including corals, sea urchins and molluscs – use to make their hard parts. If glitter is messing with that process, we could be looking at a serious threat to ocean life. A crystal-growing machine Under the microscope, we saw that glitter particles acted like little platforms for crystal growth. Minerals formed all over their surfaces, especially around cracks and edges. It was not a slow build-up – crystals appeared within minutes. This can complicate natural processes. Marine creatures use very precise conditions to make their shells the right shape and strength. When something like glitter comes along and changes the rules – speeding up crystal growth, changing the types of crystals that form – it could mess with those natural processes. Like baking a cake and suddenly having the oven heat up to 1,000°C, you might still get a cake – but it will not be the one you intended to cook. Worse still, as the crystals grow, they push against the layers of glitter, causing it to crack, flake and break apart. That means the glitter ends up turning into even smaller pieces, known as nanoplastics, which are more easily absorbed by marine life and nearly impossible to remove from the environment. Microplastics are eaten by marine life, from fish and turtles to oysters and plankton. This affects how animals feed, grow and survive. When we eat seafood, these microplastics become part of our own diet. But our findings show that glitter does not just get eaten. It changes the chemistry of the ocean in tiny but important ways. By promoting the wrong kind of mineral growth, glitter might interfere with how ocean animals form their shells or skeletons in the first place. This problem does not stop with wildlife. The ocean plays a key role in regulating Earth's climate, and mineral formation is part of that equation. If calcium carbonate formation in the ocean changes, it could also affect how carbon moves through the planet. So, the next time you see glitter on a birthday card or in a makeup palette, remember this: it might look like harmless sparkle, but in the ocean, it behaves more like a flashy chemical troublemaker. What seems small and shiny to us could be a big, silent disruptor for the marine world. And once it is out there, it is not going away.

UK trade body urges continuation of duties on Indian PET plastic imports
The UK's Trade Remedies Authority (TRA) has published its initial findings that a countervailing or anti-subsidy measure on the imports of polyethylene terephthalate (PET) from India be maintained for a further five years. The proposal, published in a Statement of Essential Facts' this week, follows a review initiated in July last year which concluded that subsidised imports of PET are likely to recur if the measure was no longer applied and that injury to UK industry would also be likely to recur. The TRA also found that maintaining the measure is in the economic interest of the UK, a statement notes. Countervailing or anti-subsidy measures are the UK's one of three trade policy tools to counter imports which are causing or threatening injury to domestic industry, the other two being anti-dumping and safeguard measures. Countervailing or counteracting measures address imported goods which are being subsidised by foreign governments. The TRA found that while Indian imports of PET during the investigation period were low at just 24 tonnes in 2023, the subsidy programmes identified in an original European Union (EU) measure still exist and are likely to continue. The investigation also concluded that UK industry remains vulnerable to injury, with falling sales, reduced production capacity, and evidence of underutilisation among domestic producers, the TRA said. The intended recommendation is to maintain existing countervailing duty rates, ranging from 0 per cent to 13.8 per cent, until August 2029, it added. Interested parties now have until June 13 to comment on the Statement of Essential Facts' and responses will be considered before TRA makes its final recommendation to the UK Secretary of State for Business and Trade, Jonathan Reynolds. TRA, as an independent trade body, investigates whether new remedy measures are needed to counter unfair import practices and unforeseen surges of imports from around the world. Trade remedy investigations were carried out by the European Commission on the UK's behalf until Brexit. EU trade remedy measures of interest to UK producers were carried across into UK law when the UK left the EU in 2019, and the TRA is currently reviewing each one to assess whether it is suitable for UK needs. Polyethylene Terephthalate (PET) imported from India is a type of plastic commonly used in food and beverage packaging, including bottles and containers.
