Up to a quarter of all plastic flowing from rivers into the ocean are microplastics, delivering more than 260,000 metric tons in 2022, according to a new study.
The rivers transported some 263,000 tons of microplastics to the oceans in 2022, according to a new model published in Science. The study reveals that intense rains can mobilize large amounts of particles accumulated in the basins and warns that climate change could intensify these episodes.
