Shijiazhuang city is shrouded in smog.
This study mainly uses the data published by China Center for Disease Control and Prevention from 2004 to 20 12, aiming to prove that long-term exposure to air pollution will greatly reduce life expectancy, and that particulate pollutants are the biggest environmental threat to human health at present.
The Peking Center of the University of Chicago quoted Zhou Maigeng, one of the authors of the study and deputy director of the Center for Chronic Non-communicable Diseases Prevention and Control of the China Center for Disease Control and Prevention, as saying: "The important information revealed by the study will help improve policies to improve the lives of people affected by severe air pollution in China and around the world."
"Our research results show that in the long run, these changes will bring great benefits to the health of China people." He, an assistant professor at the Hong Kong University of Science and Technology, said, "If all China can meet the first-class standard of PM 10, that is, 40 micrograms per cubic meter, then at least 3.7 billion years of life can be saved."

In fact, this is not the first time that the research team has studied the relationship between heating policy and life expectancy in China.
As early as July 8th, 20 13, they published a study in the Proceedings of the National Academy of Sciences, saying that the serious air pollution caused by coal burning in the north of China for decades has reduced the average life expectancy by at least five years compared with that in the south.
Increasing heating can prolong life?
According to the Beijing Center of the University of Chicago, since the last paper was published, China has also made more efforts to improve air quality. China is changing the main heating mode from coal-fired boilers to gas-fired boilers or electric boilers, and has closed many polluting factories. As a result, air pollution has been significantly improved in China's most polluted cities, such as Beijing.
The contribution of automobile exhaust to air pollution can not be ignored.
Similar research has been done for a long time, but the centralized emission of soot will definitely have a negative impact on air quality. But this is not the whole problem.
"At present, the impact of soot on air quality is getting smaller and smaller. The main components of PM2.5 in big cities are automobile exhaust and dust. According to insiders of Zhongneng Supply, the fuel supplied to Beijing is for exclusive use. In other words, the automobile exhaust that has brought severe smog weather for many times is already the best product in China. "
It has also been pointed out that according to the epidemiological conclusion, according to the "20 10 Global Disease Burden Study", in China, unreasonable diet is the first cause of people's shortened life span, followed by hypertension, smoking and air pollution.
Considering that the causes of air pollution are very complicated and difficult to sort out, I'm afraid it's a little pale to rely only on some test data. It is probably wrong to think that everything will be fine as long as you raise one point.
Environmental pollution will certainly be harmful to human beings. Only by improving heating methods and reducing pollution will things change.
