Questions abound on microplastics from road traffic

According to an estimate, tyre wear particles accounts for at least half of the Swedish microplastics emissions. While tyre particles are actually rubber, they are often included in the definition of microplastics. In 2017, the Swedish National Road and Transport Research Institute (VTI) was...

Using modeling to map out ways to mitigate traffic related particulate matter in Iceland

Exceedances of the health limit for particulate matter (PM10) pollution, due to traffic, occur several times a year in the capital area of Iceland. Because of the adverse health effects of PM10 pollution finding ways to reduce this pollution is very important. To model possible mitigation...
