Large amounts of rubber particles are dispersed into the environment due to tire wear. The rubber contains a wide range of chemicals, including several of environmental concern. The purpose of this thesis, which is based on six papers [I–VI], was to assess the ecotoxicological hazard and risk associated with tire wear particles, with a main focus on the aquatic environment. A method was develop...

Tire dust is a significant pollutant, especially as a source of zinc in the urban environment. This study characterizes the morphology and chemical composition of heavy metal particles embedded in tire dust and traffic-related materials (brake dust, yellow paint, and tire tread) as measured by a field emission scanning electron microscope equipped with an energy dispersive X-ray spectrometer (F...

PM10-2.5 mass and trace element concentrations were measured in Winston-Salem, Chicago, and St. Paul at up to 60 sites per city during two different seasons in 2010. Positive Matrix Factorization (PMF) was used to explore the underlying sources of variability. Information on previously reported PM10-2.5 tire and brake wear profiles was used to constrain these features in PMF by prior specificat...

Tire-tread material has a zinc (Zn) content of about 1 wt %. The quantity of tread material lost to road surfaces by abrasion has not been well characterized. Two approaches were used to assess the magnitude of this nonpoint source of Zn in the U.S. for the period 1936-1999. In the first approach, tread-wear rates from the automotive engineering literature were used in conjunction with vehicle ...

In recent years, with the continuous increase of car ownership per capita, tire wear particles (TWPs) from road have been widely detected in various environmental media, and their behavior influence attracted wide attention. Using Web Science Core Collection (WOSCC) as a literature search platform, we mapped research progress TWPs publication trends, international cooperation, journal distribut...

Abstract In this study, we aimed to develop a new method for measuring tire-wear particles of less than 2.5 μm generated from vehicle use. We also devise evaluating the emission factor particles. To an evaluation particles, examined several factors, such as how tire components in airborne collected on sampling filter were measured, comparison obtained laboratory study and on-road using test veh...

Tire microplastics (TMPs) are identified as one of the most abundant types microplastics, which originate from rubber with intended or unintended release. While increasing knowledge about TMPs concentrates on tire wear particles (TWPs), other potential sources like recycled crumb (RTC) and repair-polished debris (TRD) much less understood. Excessive levels their additives have been fragmentaril...
