Airborne microplastics from traffic pollution may be entering the world’s oceans at a similar rate to that from rivers, according to new research Tuesday warning that the particles may also speed up Arctic ice melt.<\/p>\n

As global plastic production continues to surge, the study is the first attempt at quantifying how much plastic from road vehicle tyres and brake pads is dispersed and deposited by air currents.<\/p>\n

Microplastics\u2014tiny particles produced when larger plastic chunks break down as well as microfibres from clothes and other materials\u2014have been found atop some of Earth’s highest glaciers and at the bottom of its deepest trenches.
\nResearchers in Norway and Austria took data on how much microplastic is produced by road transport and combined them with simulations of where they might be transported on wind currents.
\nThey found that around a third of all road microplastic\u2014roughly 50,000 tonnes\u2014end up in the world’s oceans every year.
\nThe estimated range of 40,000-100,000 tonnes of aerial microplastic compares with the 65,000 tonnes deposited into the ocean from rivers annually.
\n“Atmospheric transport\u2014a source that is underestimated or not even considered\u2014has the same impact on microplastic pollution in the ocean as riverine transport,” Nikolaos Evangeliou, from the Norwegian Institute for Air Research and lead study author, told AFP.
\nHe said that microplastics were already having an impact on human and animal health as they are able to absorb organic compounds and toxic heavy metals, which are then ingested and enter the food chain.
\nMost road traffic plastic emissions are produced in vehicle-heavy regions such as North America, Northern Europe and South East Asia.
\nLong-term menace<\/b>
\nEvangeliou and his team found that when they simulated where these emissions were transported by global weather patterns, a significant amount was likely ending up in the Arctic.
\nGiven the plastic particles’ dark colour, which absorbs more of the Sun’s heat, they said the pollution could affect the rate of ice melt there.
\n“Such small particles may act as light-absorbing impurities when deposited on snow and ice surfaces decreasing surface (heat reflection) and accelerating melting,” Evangeliou said.
\nWith several countries promising to end production of petrol and diesel vehicles in the coming decades, the paper published in Nature Communications<\/i> suggested that road plastic emissions would continue to pose a growing environmental threat as tyres and brakes would likely be the same even on electric models.
\n“Road microplastics environmental impact as they are derived by materials made from fossil fuels such as ethylene and propylene,” said Evangeliou.
\n“Thus, the larger need for plastics result in larger emissions of greenhouse gases.”<\/p>\n
