Team efforts revealed Two important difficulties in dealing with nurdle spills. Nurdles are so small and light that they are easily carried over long distances by waves and ocean currents. And when they finally wash up on shore, they can burrow deep into the sand. In fact, the study revealed that the worst affected places were near Kovalam and Dhanushkodi. Researchers found staggering concentrations of nurdles on beaches far from the wreck site, ranging from 1,500 to 3,500 pellets per square meter of shore.
A year later, nurdles are still being found along the coastline, and scientists say the true environmental impact of the spill may only be beginning to become clear.
Plastic nurdles can take thousands of years to completely disintegrate. However, exposure to sunlight and oxygen makes the plastic brittle, and wind and waves can break the nurdles into even smaller pieces. Even more worrying, Vincent said, is how the nurdles are affecting local wildlife. When nurdles colonize beach sand and seafloor sediment, they are colonized by insects, shellfish, crustaceans, and other benthic organisms. Poisonous pellets can be mistaken for food.
“Nurdles can act like little sponges for pollution, drawing toxic chemicals such as heavy metals and persistent organic pollutants to the surface,” Vincent says. “When marine animals ingest them, these contaminants can enter their bodies and cause harm.”
This is what happened during a similar disaster – a catastrophe. X press pearl It occurred off the coast of Sri Lanka in June 2021. The United Nations called the shipwreck and the resulting Nardole spill an “accident.” biggest environmental catastrophe Since the 2004 tsunami hit the Indian Ocean. The ship was carrying 81 containers of hazardous materials, including at least 34 containers of plastic nurdles, equivalent to approximately 84,000 bags of plastic nurdles like those found on board. Elsa 3. before it sinks, X press pearl It had been burning for days. A few weeks later, hundreds of dead animalsTurtles, dolphins and even whales have all been found washed up on beaches.
Part of the problem is that, as a relatively new type of environmental pollution, people don’t quite know what to do when millions of nurdles escape into the environment.
“There are huge gaps in the global response to pellet spills,” said Dharmesh Shah, an independent environmental policy analyst in Kerala. “Oil spills have been happening for years, so we have standard protocols and spill response mechanisms. But with pellets, we don’t know what to do.”
In November 2023, the advocacy group Environmental Investigation Agency A report has been published This shows how purification techniques aimed at nurdles often fail in practice. after that X press pearl disaster, Alliance to End Plastic WasteA non-profit organization funded by the petrochemical industry donated eight “Sweepy Hydro” beach cleaning machines. but, Bloomberg Green Survey After only a year, the machine was found to be out of use as it could only clean beach surfaces. Some vehicles became clogged with wet sand, and a lack of fuel and spare parts made operations difficult. Instead, local women removed the pellets by hand six days a week.
Nurdle pollution is bigger than just a shipwreck. Jace Tunnell is a Texas-based marine biologist and founder of Nurdle Patrol. For the past eight years, Tanel has trained citizen scientists around the world to track nurdles and used this crowdsourced information to create a public database showing hotspots of nurdles contamination, often areas around plastic production facilities.
“If a business does not have septic systems, separation equipment or retention ponds in place, nurdles can escape during production, spill on the ground, and be carried off-site by rainwater,” Tanel says. “Companies need to keep pellets within fence lines, but many companies struggle to do so.”
Nurdal pollution is not just a marine problem, Tunnel added. “In the United States, plastic pellets are also transported by rail,” he says. “We’ve conducted 170 nurdles surveys along railroads, and only 10 of them were without nurdles. They’re also in the desert, far from the coast.”
Mediterranean Shipping Company (MSC) returned to India, owner of sunken ship MSC Elsa 3, Deposited bank guarantee of US$136 million and the Kerala High Court. The funds are intended to serve as collateral held by the court while the state calculates the damages caused by the accident. To date, there is no public evidence that this money has been spent to support cleanup efforts.
So for now, while local communities and environmental nonprofits clean beaches by hand, Vincent and his team track how these pollutants, plastic pellets, continue to evolve and decay.
“We don’t fully understand the long-term effects this will have on our coastline,” Vincent said. “But there is one thing we know: only effective policies and strict regulations going forward can save us from these disasters.”
