90% of people in the world are breathing polluted air.
90% of people in the world are breathing polluted air.
Slight air pollution is also associated with increased mortality.
Everyone knows that PM2.
However, there is another common air pollutant-NO2 that often fails to attract everyone's attention.
Not long ago, another study led by Professor Kan was published in the latest "British Medical Journal" (BMJ) on the relationship between the short-term increase in NO2 concentration and the risk of death in 398 cities in 22 countries.
It is found that the harm of NO2 to mortality is almost linear, and there is no obvious threshold.
This retrospective cohort study used data from the National Health Insurance Service of Korea.
Among them, the personal exposure levels of PM2.
The results showed that at baseline, the average (SD) age of the 78830 participants was 54.
Diagnostic exposure to NO2 is associated with an increased risk of PD, with the highest participants having a 41% increase in PD risk compared with participants in the lowest quartile of air pollution (RR=1.
It can be seen that air pollution, especially exposure to high concentrations of NO2, will increase the risk of PD.
