Air pollution exposure is related to the environment Seven million Pre -death deaths yearly all over the world. When we predict of urban air pollution, diesel path emission is usually presented as a key offender – rightly, given The results of the previous research. However, Our latest research It shows that dust from the brake pad might be more harmful to our lungs.
Dust made by road clothing, tires, and brakes, which is understood “Non -ejaculate Extract”Now there may be a big number of road transportation, leaving the trail out of the best way In many European countries. Of these, the brake dust is usually a very important partner, nevertheless it will not be yet subject to the rule. Diesel is less aware of the potential health effects of brake dust than dust.
We grew up Cells in the lab To imitate the lung layer, and expose these cells to each the brake dust and diesel pathway. The brake dust proved to be significantly more harmful in various cells for the cells which can be related to lung diseases resembling cancer and asthma. Interestingly, we have now found that removal of copper from the brake dust has reduced these effects.
Nevertheless, the present vehicles within the UK Only the target route emitting. Our searches show that non -existing emissions are also needed to think about. Correction of a brakepad generally is a option to reduce the health burden imposed by these emissions.
The brakepad consisted of asbestos fibers to address high heat first. However, asbestos was banned within the UK 1999 Due to links to lung disease. As a result, the motor industry designed latest brake pad lines, including Non -Osbestos Organic (NAO) Pads utilized in vehicles commonly used today.
We compared the damage to the dust by wearing several types of pads. Ironically, we have now found that the pads containing asbestos were designed to interchange, the dust from the NAO pad was probably the most toxic for lung cells that not only other kinds of pads. It was from dust, but in addition a diesel route. Some effects on our exposed cells are related to diseases resembling lung cancer, lung fibrosis (lung stains), asthma, and chronic obstruction pulmonary disease.

Previous research has shown that air pollution particles could have metals Toxic effects. We measured the metal material in a wide range of brake dust and diesel pathway. AI's techniques identified high copper content, describing the brake dust from the NAO pad.
We also found that this copper can enter the lung cells. The most interesting thing is that once we treated this brake dust with a chemical to make copper ineffective, its toxic effects decreased. This shows that copper is causing at the least some harmful properties of this dust.
About half We come from wearing a brake and tire of all of the copper within the respiratory air. Various studies conducted by other research groups have found that prime variety of copper is related to exposure to The Function of Bad LungAnd The overall risk of death.
EVs will not be perfect
Is a A A huge body of proof Air -powered dust is damaging our health. Unfortunately, while the switch to electric vehicles (EV) will eliminate the road emission, which incorporates toxic gases in addition to dust, it’s going to not eliminate the road, tire and brake dust. Studies show that, because they’re heavy, so electric vehicles can produce more non -exist dust than Petrol or diesel vehicles -The label for the emission is clearly not correct.

Are equipped with some EVs Re -born brakes The system that enables the engine to operate as a generator, slows down the automotive. However, the EVs are still equipped with the friction breaking system, which helps bring the automotive to the whole stop, so that they still produce brake dust.
Incoming Euro 7 emission standards This will likely be introduced In November 2026 Brakes will place limits on dust emissions that may promote innovation for brand new growth Brake meter Or Method of stuck dust. They also can deal with the traffic calm and road design to reduce a stop start and aggressive driving style. These two increase the brake dust emissions.
New brakepad formulations can reduce the entire level of dust emission or be designed to exclude toxic ingredients, because the asbestos was previously eliminated. In particular, within the United States, each California and Washington have legislated Reduce copper content Within the brake pads, even though it was mainly in response to copper flow from the brake dust within the waterways, which affects aquatic life.
Unhealthy emissions are throughout us, make -up About 60 % Of the pollution particles derived from vehicles within the UK. It is vital for us to confess that there isn’t any air pollution for which one is for Set up the surface of safe exposure.
When we modify the electrical cars, science and regulations must turn these emissions as serious as the trail is from the pipe.
