Tire and road wear particles
Tire abrasion is expected to be the single largest source of polymers particles in the environment. Emissions of the resulting tire and road wear particles (TRWP), aggregates of tire and road material, are estimated between 1 and 2 kg/y for each citizen in Germany. Yet methods to accurately and sensitively assess the presence, distribution and sinks of these particles in the environment are poorly developed. We develop and utilize methods based on zinc as well as on organic markers to study the environmental occurrence, distribution, transport, removal and aging of TRWP in laboratory experiments and under environmental conditions.
