Pollution of motor transport highways by particles from tire and road surface wear has a disastrous influence to human health
Download in .pdf format

During motor transport operation, elevated concentrations of solid particles are formed in the air over the roadway as a result of particulate matter emissions from vehicle exhaust gases, tire and road surface wear particles, background air pollution and other processes. The content of tire and road surface wear particulates in the air over the roadway, as it has been specified in the previously submitted materials of the Russian delegation, amounts up to 60% from the total percentage of solid particles (WP-29-160-39). This paper presents further research into this subject.

26. Recalling the submission of GRPE-65-20, WP.29-160-39, WP.29-161-22 and GRPE-68-10 on tyre and brake wear and vehicle indoor air quality, the expert from the Russian Federation introduced GRPE-69-03 with further test and research results. He underlined the evidence that tyre wear would contribute to air pollution not only with solid particulates but also with gaseous pollutants. He announced that, to address this issue, the standard GOST R 51206-2015 on cabin air filters and purifiers was under development.

27. The Chair of the IWG on PMP provided an overview of the latest activities of the IWG (GRPE-69-25) focusing (i) first on the exhaust emissions, in particular on the 23 nm cut-off size confirmation given the state of technology as well as the development of a robust procedure to measure particles down to 10 nm in case of future needs, (ii) then on the particle emissions during regeneration and the particle emissions from Non-Road Mobile Machinery. He reported that the Group had addressed (GRPE-69-24) the concerns expressed in GRPE-69-03 and proposed a possible road map on how to proceed further with the issue of particles from tyre and brake wear (GRPE-69-23).

28. GRPE acknowledged the information provided by the IWG and the Russian Federation, endorsed in principle the roadmap proposed and requested the secretariat to reserve a room for a meeting prior to the January 2015 GRPE session.

43. The expert from the Russian Federation introduced GRPE-69-03 while discussing item 7 on Particulate Measurement Programme (see para. 26).
