That’s according to a recent UK government study in conjunction with the Commission on the medical effects of air pollutants. Scientists have looked for evidence of health effects from exposure to non-waste particulate matter from road vehicles.
The report shows the contributions of exhaust gas, braking, tire wear and road wear to the total amount of PM10 and PM2.5, two fine particles that contribute to air pollution.
Air particulate emissions account for less than 10% of the UK’s particulate emissions (PM), and that share will increase as electric vehicles without exhaust become increasingly popular.
Some monitoring locations to perform research include London North Kensington and London Marylebone Road.
The average taken from 30 baseline locations showed that emissions accounted for 1% of PM10 dust and 2% of PM2.5 dust, while brake and tire wear, accounting for 2% of PM10 and PM2.5 dust emissions. In which 1% of PM10 and PM2.5 dust particles are due to wear while traveling.
In London North Kensington, flue gas pollution is measured at 2% PM10 dust and 4% PM2.5 dust. PM10 dust due to brake and tire wear is at 6% and PM2.5 at 5%. Moving wear contributed to PM10 and PM2.5 dust was 2%.
While in 15 roadside locations, exhaust gas accounts for 4% of total PM10 and 5% of PM2.5. The PM10 index for brake and tire wear is measured at 11% and PM2.5 at 8%. PM10 is 4% and PM2.5 is 4% on the move.
In the London Marylebone Road area, PM10 emissions were measured at 6% and 9% PM2.5. Braking and tire wear is measured at 16% PM10 and 13% PM2.5. Wearing while moving accounts for 6% of PM10 levels and 5% of PM2.5 levels.
Dangerous particle pollution like?
Both PM10 and PM2.5 particles are hazardous to health if they enter the respiratory system both in the short and long term. Common health problems caused by exposure include respiratory and cardiovascular diseases, such as asthma, death from cardiovascular and respiratory diseases and lung cancer.
According to a report by the World Health Organization, PM2.5 seeds carry a higher risk of death than PM10 seeds.
In 2018, WHO estimates that about 7 million people die each year from exposure to fine particles in polluted air. To prevent these microscopic dust particles, the best way is to reduce air pollution and prevent fine dust from worn tires.
The device helps to recover microplastic particles produced by tires
Recently, a group of students named The Tire Collective from Imperial College London and Royal College of the Arts have been awarded for their equipment to capture microplastics emitted from tires. The device is mounted on a wheel and uses static electricity to collect these plastic particles. It was introduced to reduce the amount of air pollution that is emitted by tire and brake wear.
