A recent research conducted by Michael Scheurer and Moritz Bigalke at the Geographical Institute of the University of Bern revealed that even remote mountain regions in Switzerland are contaminated with microplastics. The scientists warned that the situation might be worse in other countries where waste management practices aren’t as effective.
The researchers analysed soil samples from 29 river flood plains in nature reserves across Switzerland. They found microplastics, fragments under 5 mm in size, in 90% of the soils. They believe the particles are carried across the country by the wind.
“We were really surprised,” said Bigalke. “All the areas were in national parks. We thought we might find one or two plastic particles, but we found a lot.”
