1 million people’s data suggest that air pollution not only hurts the lungs, but also hurts “God”!

90%of the world’s people are breathing air. Among the top ten health threats released by the World Health Organization, air pollution ranks first. Obviously, this is a common problem in the world, but the actual situation and academic research in various countries and regions are different.

In 2019, Professor Xi Haidong of the School of Public Health of Fudan University published a study on the world’s top issue of “New England Medical Journal” (NEJM) that slight air pollution was also related to the increase in mortality. At the same time, as the PM10 and PM2.5 concentration increased, the mortality rate continued to increase.

Everyone knows that PM2.5 fine particles are larger than viruses, smaller than bacteria, and are prone to toxic substances into the human body, so they know the harm of PM2.5.

However, another common air pollutant, NO2, often cannot attract everyone’s attention. The NO2 in the environment mainly comes from the emissions of the exhaust gas and the exhaust gas of the power plant. With the improvement of people’s living standards, more and more automobile exhaust emissions are increasing, so the problem of air pollution caused by NO2 emissions is becoming more and more serious.

Not long ago, another study led by Professor Xi published in the latest research on the latest “British Medical Magazine” (BMJ) to conduct a short -term increase between NO2 in 398 cities in 22 countries and the risk of death. After a comprehensive study, it was found that the harm of NO2’s mortality was almost linear and there was no obvious threshold. In other words, the mortality will increase with the increase of NO2.

Recently, scientists from South Korea have studied whether air pollution has affected the development of Parkinson’s disease (PD). The potential connections between the risk of the risk of the risk of the risk of the risk of the risk of the risk of the risk of the risk of particulate matter (PM2.5 and PM10), NO2, ozone (O3), sulfur dioxide (SO2), and carbon monoxide (CO) and PD were studied exposed to particulate matter

This retrospective queue studies the data of Korean national health insurance services. Among the 10,21208 Korean people in the database chose to live in Seoul from 2002-2006 as a qualified person. A total of 7,8830 adults over 40 years old and no PD were included in this study. From 2007-2015, each participant will be followed up every year.

Among them, the exposure levels of PM2.5, PM10, NO2, O3, SO2, and CO are estimated at the regional level based on the residence address of the participants. In order to evaluate long -term exposure to air pollution, the time change of each participant’s 5 -year average air pollutant exposure. The main result is that after adjusting the relationship between population, socioeconomic factors, and medical complications, the relationship between air pollution and the risk of PD occurs.

The results showed that at the baseline, the average (SD) age of 7,8830 participants was 54.4 (10.7), and 41070 (52.1%) was women. During the study, there were a total of 338 new diagnosis of PD patients. In general, the increase in the risk of NO2 and PD, of which, compared with the lowest quarterly air pollution participants, the highest participant PD risk increases by 41% (RR = 1.41; 95% CI, 1.02 1.02 -1.95). However, it was not found that there was a statistical relationship between the incidence of PM2.5, PM10, O3, SO2, or CO and PD.

It can be seen that air pollution, especially NO2 high concentration exposure, increases the risk of PD.
