Perhaps the air is ruining your health right now, because in the city air is often observed high levels of carbon dioxide, methane, ozone and other harmful substances.

Really dirty air is more harmful than, say, the smoke from cigarettes?

As far as dirty air in cities?

According to the researchers, if the level of these substances is greater than 100 parts per billion, the human body serious harm is done. But, to their surprise, in most cities ozone level is only 10-25 ppb and the nitrogen - and less.
the dirtiest city in the world - Tyanin
The collected data were compared with the results of computer tomograms of the heart and lungs of 15 000 people. It turned out that the symptoms associated with emphysema, have indeed been observed even in non-smokers. Exactly how the calculations were made is not known, but in the end, scientists announced that the cause of the destruction of the lungs can become even a small concentration of ozone. Damage nitric oxide was less pronounced - study showed that its concentration falls every year.
The damage urban air
Thus, breathing polluted air with ozone for the past ten years, people have applied myself the same harm as if thirty years of cigarette smoking. According to scientists, in the future, polluted air becomes even more dangerous - the average global temperature increased almost every year, indicating that the onset of global warming. And with global warming, we recall, in the world there is accumulation of greenhouse gases, including ozone and dangerous.
