It is clear that cars with Combustion engine They are a clear example air pollutionThe field consequences of this pollution become more and more well -known. In fact, it was recently discovered that they are behind many cases of lung cancer in non -instrumental. Nevertheless, there is something that has nothing to do with the exhaust pipe, which is also dangerous and even found in electric cars: Brake powder.
In a study recently published in British medical journal Scientists Southampton University They show that brake dust is more dangerous for pulmonary cells that the derivative of emissions diesel tubes. The problem is that although they are not the first that indicate this problem, they mention that in the UK where the study was conducted, No legislation This regulates the amount of specified dust produced by vehicles. Also not in other parts of the world; Although in Europe it does so They begin to act.
It is very necessary by law and, by the way, Find alternativesField materials used today to cover brake pads They developed specifically for Replace asbestos This was used in the past. After it was proved that this material is very toxic, it was resolved Change the compositionThe field, however, have new coatings High copper contentwhich also turned out to be very toxic for the lungs. Therefore, in order to prevent the influence of brake dust, it is important to publish this problem and take measures in this regard.
Unknown danger of brake dust
When brakes, tires and even road material They are wear, released particles known as Emissions without escaping. These are not such environmental pollutants as emissions of exhaust pipes. However, they can be very dangerous to health. Perhaps more than those that are received from combustion engines. It was a hypothesis of the authors of the study that has just been published. To check it, They cultivated lung cells In the laboratory.
Then they contacted them with particles of both brake powder and emissions of a diesel car tube. At the same time, they saw that the cells suffered from brake dust. This is damage that if these cells were real lungs, could cause diseases such as asthma, cancer or chronic obstructive lung disease (hobble)The field but the most curious thing is that, excluding copper from the composition of brake dust, these effects were significantly reduced.
Necessary legislation
Burning engines are increasingly adjustable. Even the passage in some cities is prohibited by vehicles that are not effective in this regard. Everything should take care of the environment and light citizens. But no one thinks about brake dust. Or almost no one.
In Europe, EURO 7 was created for several years. Improve air quality Protection from exposure Road transportThe field includes emissions of exhaust pipes, of course. But Brake powder and tire wear.
These measures have not yet been implemented. For example, it takes time to set the best methods for a quantitative assessment of emissions of the brake dust of the vehicle. First of all, attention should be given PM10 particlesField, that is, those whose diameter Less than 10 microns. With these dimensions, they are able to penetrate into the tissues of the lungs and cause damage, such as those that these English scientists saw in their cellular cultures.
If all this is implemented correctly, in the future, in ITV, also analyze the brake dust of your car. In case it releases too much, this should not spread. Although, at the same time, there is alternative material, whose wear is not toxic, better than better.
