In Switzerland, landed between 1988 and 2018, around 200'000 tons of micro rubber in our environment. To come to this impressive result, Researchers Bernd Nowack of the research, Empa. The largest part of which (97 percent) comes from the abrasion of tires.
micro rubber is less in the public focus as a micro-plastic, which was also detected in the human body already. However, the calculations at Empa show researchers that the tiny rubber particles from tires and lawn a low share - of art, at least present a much greater Problem.
Of all the released into the environment, Polymer-based micro-particles, only seven percent of plastic, 93 percent of tires are abrasion-resistant. "The amount of micro rubber in the environment is huge, and thus highly relevant", was Nowack, in a communication of the Empa by the Thursday quote.
edge of the strip of micro rubber
The grated rubber swirls through the air and lands on the strip on the right and left of the road. Three-quarters of the total amount of the rubber particles remain on a five-Meter-wide strip off the road, such as the Empa wrote. About five percent come in the rest of the floors, almost 20 per cent of land in waters.
at Least water from the Road and the tyre wear now better removed, so that significantly less micro-rubber is expected to land in the waters. Since the year 2000, stricter rules on the reprocessing of water, and to prevent the pollution of soils.
hazard to humans is small
in Spite of the impressive amount of micro rubber Christoph, this manuscript of the Empa estimates the risk to humans is low. "The proportion of tire wear particles in the inhaled fine dust is also traffic-orientated locations in the low single-digit percentage area" quoted in this manuscript the results of a study from the year 2009. Nowack also stresses the fact that between the micro-rubber micro-plastic is a significant difference, so that the particles could hardly be compared.
The research team used for its calculations the data for the Import and Export of tires. Based on this model, the scientists then transferred the behavior of rubber on roads and in road wastewater. The results they reported in the journal "Environmental Pollution".
