The hills are alive with the signs of plastic: even Swiss mountains are polluted

Major study finds microplastics in soil across Switzerland and scientists warn urgent research is needed into impacts on food safety as other countries may be worse affected

Microplastic pollution contaminates soil across Switzerland, even in remote mountains, new research reveals. The scientists said the problem could be worse in other nations with poorer waste management and that research was urgently needed to see if microplastics get into food.

In the first major study of microplastics in soil, the researchers analysed soil samples from 29 river flood plains in nature reserves across Switzerland. They found microplastics, fragments under 5mm in size, in 90% of the soils. The scientists believe the particles are carried across the country by the wind.
