A study has revealed that 96% of the microplastics flowing into the ocean via rivers worldwide are concentrated in developing countries, such as Southeast Asia. Heavy rainfall rapidly amplifies this microplastic outflow, suggesting that as extreme weather events become more frequent due to climate change, microplastic pollution will become even more severe.
Transported by air, particles of microplastics come mainly from PET bottles, textiles and packaging. About 40% end up on agricultural land, in lakes and rivers, according to a first systematic research Transported by air, 219 tons of microplastics arrive each year in Swiss soil and waters, according to a study by l'Empa, l'Eawag and d'Agroscope. About 40% of these particles end up on agricultural land, in lakes and rivers.For the first time, a t…
A study led by the University of China was based on models to determine the level of pollution and how it could be intensified with extreme weather events.
The world’s rivers brought some 263,000 tons of microplastics to the oceans in 2022. A 96% discharge from the global south, and Southeast and East Asia contribute more than half of the total. The entry The world’s rivers brought some 263,000 tons of microplastics to the ocean in 2022 was first published in Digital Process.
