According to a new study by Chinese experts, Israel and the United States, the smoke from burning coal causes air pollution that could cause people in northern China to lose three years of life compared to the South.
The study was based on air quality data in 154 cities in China from 1981 to 2012. Accordingly, pollution levels in the north were 46% higher.
Poor air quality in the north causes average people an average loss of 3.1 years compared to the south. The cause is that diseases like lung cancer or stroke occur more commonly.
“The mortality rate has increased dramatically, not only in young people and the elderly but also in middle-aged people.” Air pollution affects everyone, “said Michael Greenstone, volume and environment at the University of Chicago, co-authors of the study.
In the past, coal was widely used in northern China, where the climate was cooler, partly because of government policies to provide free coal to households. The northern part of the country is also facing more severe dust, especially in autumn and winter, when people burn more coal for heating.
Increasing dissatisfaction with the dense cloud of smoke led the government to embark on an anti-air campaign in which households were forced to replace coal heaters with electric or gas heaters. These efforts have been effective, Greenstone said.
Last month, however, the government admitted it was still under pressure to reduce PM2.5, which is the smallest dust in air pollution that is most harmful to health
Continued air pollution has prompted many Chinese people to die prematurely, especially in industrialized areas, according to statistics on air quality and life by researchers at the Institute of Energy Policy. University of Chicago made.
The average Chinese person can live an additional 3.5 years if the PM2.5 level remains below the World Health Organization (WHO) standard. Beijingers can live an additional 6.4 years if PM2.5 is international, while residents in Harbin will spend 6.9 years.
In the past, there have also been studies showing the alarming effects of China’s smoke pollution on health.
Dust is associated with nearly one-third of all deaths in the Beijing-Tianjin-Hebei area, the Yangtze River Delta and the Pearl River, according to a 2013 mortality statistics. Another poll conducted by the US Health Impact Research Institute earlier this year showed that air pollution caused an estimated 1.1 million Chinese deaths.
