In densely populated and densely populated cities, vehicle exhaust pollution can be very serious. We all know that car exhaust is very harmful, and the main pollutant of car exhaust includes carbon monoxide.
Nitrogen oxides, hydrocarbons.
Lead, sulfides.
The harm to the human body is mainly manifested in causing various diseases and seriously damaging the respiratory system.
And it is very carcinogenic. So someone asked, "How many floors do you live above without inhaling car exhaust", let's take a look at this question together.
If you live above any floor, you won't get car exhaust.
The general idea is that the 9th to 11th floors of the upper floors are exactly the ash floors, and the dirty air stops at this height. However, physics experts pointed out that the statement that about 10 layers are "ash layers" is inconsistent with the common sense of atmospheric physics. Because at a height of thirty or forty meters above the ground, the dust does not stop.
Dust does not stop in the stratosphere of the atmosphere from 10 km to 52 km above the ground. In other words, there is no so-called ash layer in ordinary high-rise buildings. In fact, according to the survey, almost all live in high-rise buildings.
Residents on floors 9 to 11 do not have a particularly "badly grounded" feel. In fact, the near ground below the meter will be larger, because the specific gravity of dust, people are generally concerned about the car exhaust because it contains lead and other chemicals, the specific gravity is also very large, so they will continue to sink in the air. Surveys have confirmed that the air quality in the underground passages is much lower than above ground.
In fact, living in a relatively high building can also inhale car exhaust, which can only be said to be relatively better than the pollution level of car exhaust living in a high-rise building.

In densely populated cities, vehicle exhaust pollution is severe.
-
The floor height that the exhaust can reach is generally 9 to 11 floors.
The floor height that can be reached by the exhaust gas of the car is:
Regardless of the type of gas pollution, the heaviest ones are on the 9th to 11th floor, because the height is mostly around 30 meters, which is exactly the height at which the particles are suspended.
The force of the street wind causes the dusty air currents to "hover" up and down a certain area between the tall buildings. Pollutants near the ground rise to a certain height with the airflow and then dissipate downward, that is, between the 9th and 11th floors.

Summary. Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.
Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.
Friend No. 1: According to your situation, the car exhaust is generally ah, and the downstairs is almost below the fifth floor is the most serious, and the higher you go, the exhaust is gone.
Doesn't the house on the side of the road say that you can float to the 9th or 11th floor?
The prostitute must be able to float to it, but the higher he goes, the less polluted his exhaust gas will be.
But there is a lot of traffic on the side of the road, and the house on the ninth floor on the south side of the road has little impact?
That's right, anyway, the higher you go, the smaller the impact.
How to prevent car exhaust in a house on the side of the road? What plants are good for in the house?
Buy some to purify the air, flowers and plants.
Okay, thanks!
You can choose those flowers and plants that are all year round, which are meant to purify the air.
Are the houses inside the community not affected by car exhaust?
Yes, if you are in the community, if you are in the house, this is a little better than the side of the road.
Our house is on the south side of the road, are the three bedrooms on the south side less exhaustive?
If you live on a high-rise floor, the exhaust emissions will be smaller, and this will not affect you.
If I can help you, please give me a thumbs up Thank you!

No, the height of car exhaust emissions is mainly between meters and 2 meters.
The impact of pollutants emitted from motor vehicles on urban near-surface air quality is much higher than that of stationary sources far from crowds. Because the height of automobile exhaust emissions is mainly between meters and 2 meters, which is exactly the breathing range of the human body.
-
Air pollution is everywhere, as for the fourth floor, because the air convection is stronger, the air is better, and the breathing zone is the most polluted.
Enter without opening a window. The air is everywhere, and the exhaust gas is the same, because the exhaust gas is not opened, the exhaust gas that people breathe must also be discharged, or it is better to open the window to convect the air and then close it.

I think as long as there's no traffic jam downstairs, it's fine.
Look at the car from that year! The number of countries is limited according to the year! Produced on July 1, 2000 according to the national one standard, July 1, 2004 implemented the national two standard!
The main pollutants emitted by automobile exhaust are carbon monoxide, hydrocarbons, nitrogen oxides, lead, etc. >>>More
Now we talk about exhaust gas, which refers to car exhaust, that is, the exhaust gas that the car exhausts from the exhaust pipe. Vehicle exhaust is another major contributor to air pollution, and vehicle exhaust contains carbon monoxide, nitric oxide and other solid particles that have adverse effects on the human body, especially leaded gasoline, which is more harmful to the human body. >>>More
Not really, the exhaust cleaner ingredient is methanol.
Li Guoxiang, director of the Institute of Internal Combustion Engines at the School of Energy and Power Engineering at Shandong University, said that automotive fuel systems and engines are not well tolerant to methanol, and that large amounts of methanol can lead to corrosion, swelling, softening and cracking of synthetic rubber materials, as well as carburetor metal speckles. "Ordinary cars can't run on fuels with high methanol content if they aren't retrofitted. ” >>>More
A car emits harmful exhaust gas every year, 3 times larger than its own weight, and the exhaust emission standard has become a hard indicator that must be met in the annual review of motor vehicles, so for the negative impact of automobile exhaust on the urban atmospheric environment, the improvement of automobile exhaust emission standards will be one of the most direct and effective means. >>>More
