ROAD VEHICLE AS A SOURCE OF NON-EXHAUST PARTICULATE MATTER

Scientists in Canada and the United States have found that long-term exposure to PM2.5 significantly increases not only chances for cardiopulmonary problems, but also mortality from lung cancer. [...]the 7-year study (2000 to 2007) in the United States showed that the average life expectancy was extended by 0.35 years for every 10 μg/m3 of PM2.5 reduction [2]. According to source [5], the largest emitter of these particles is a braking system or better sad wearing braking systems, tire wear and eventually the road. Compared to the average IC engine used as propellant fuel, EV emits 1% less PM2.5. [...]according to this source, the use of electric vehicles would not result in a significant reduction in PM2.5 particulate emissions compared to internal combustion engines. According to this study, the PM10 most suspended PM10 particulate matter is diesel engines, while in the case of particles which do not result from combustion, the biggest source of emissions is the way in which tire wear on the road surface can also be considered.
