Country-scale calculation: How much microplastics is there in Swiss rivers and lakes?

Plastic particles less than five millimeters in size, also known as microplastics, often settle far away from their point of origin. Empa researchers have now developed a model that can be used to calculate the concentration of microplastics in Swiss lakes and rivers.

Every year, 14,000 tons of plastic end up in Swiss soils and waters, in part in the form of microplastics: Particles in the micro to millimeter range. Microplastics comes from many sources, such as cosmetics or synthetic fiber clothing. The tiny particles are also produced by abrasion and decomposition of larger pieces of plastic, so-called macroplastics.
