Scientists suspected that the destruction of the lung tissue can also occur because of dirty air. To check whether or not they had a fairly large experiment, which lasted from 2000 to 2018.
How dirty is the air in cities?
The First thing the scientists decided to drive around the different States and to measure the concentration of nitric oxide and ozone, which are among the main air pollutants. According to the researchers, if the level of these substances is more than 100 parts per billion, the human body . But, to their surprise, in most cities, the ozone level is only 10-25 parts per billion and nitrogen and the less.
the dirtiest city in the world — Tyan'in
The Collected data were compared with the results of computer tomography of the heart and lungs 15,000. It turned out that the symptoms characteristic of emphysema, do was observed even in non-smokers. How exactly the calculations were made is unknown, but in the end, scientists announced that the cause of the destruction of the lungs can be even a small concentration of ozone. The dangers of nitric oxide was less pronounced — the study showed that every year its concentration falls.
Harm urban air
Thus breathing polluted ozone air in the past ten years, people cause the same harm as when thirty years of Smoking cigarettes. According to scientists, in the future, the polluted air will become even more dangerous — the average global air temperature , indicating that the onset of global warming. And with global warming, we will remind, on the Ground observed the accumulation of greenhouse gases, including dangerous ozone.
From the dirty air, people are dying. ?
And you know what else it can collapse the lungs? Sounds pretty scary, but the human lungs can be damaged even during Chinese therapy — acupuncture.
