Factsheet 11: Microplastics in wastewater treatment - Development of sampling and analysis methods for detection of input quantities into surface waters

It is not easy to determine how much microplastic is contained in wastewater and sewage sludge. In addition to plastic, countless other particles and substances are present. To reliably determine the concentration of microplastic particles, complex procedures for sampling as well as for removal of foreign substances and analysis of the microplastic particles are required.

The methods currently available for the analysis of microplastics in environmental matrices are primarily designed for particles in the size range of 1 μm to 5 mm. Smaller particles below 1 μm have hardly been detected so far. However in contrast to larger particles, these are able to enter cells and have a higher potential for adsorption of pollutants due to their relatively larger surface.

Tyre Wear in the Environment
August 2017
January 2021

Plastics in the environment are an increasingly serious challenge. As macroplastics deteriorate, such as through tire abrasion, the resulting microplastics can enter the aquatic environment through a variety of entry points. As vehicle traffic increases, there is an inevitable increase in microplastics from worn tires ending up in the environment.
