Oslo microplastic fallout measured at 30 times Svalbard level
Svalbard WirePublished 4 NovemberReport by the Wire.
Zeppelin Observatory on Svalbard is one of three stations in the national monitoring of microplastic falling from the air, with Birkenes in Agder and Sofienbergparken in Oslo. In 2025 the Oslo station measured about 30 times the Svalbard average and about 13 times the Agder level, the Norwegian Environment Agency said on 4 November.
Each station took 12 samples over the year, each covering 14 days. The release is mainly about Oslo, where particles from car tyres made up about 75% of the microplastic.
