china 'winning' war on smog, helping life expectancy - study - where to buy air purifiers

Beijing -
According to a study by American universities, China seems to be "winning" The air pollution war, making such great progress that life expectancy may increase by more than two years.
The Chinese government has been fighting to clear smog, reducing life expectancy in some areas and prompting Chinese citizens to buy masks and air purifiers to protect themselves during peak pollution periods.
In a research report released on Monday, the University of Chicago said that although the world's largest polluting countries still have a long way to go to meet national and international air quality standards, the result "shows that the country is winning the pollution War ".
According to the daily data of more than 200 monitors in China from 2013 to 2017, the analysis found that the city has reduced the level of PM 2. 5 -
Tiny air particles considered to be the most harmful to health
The average growth in just four years was 32%.
If this reduction continues, the average life expectancy of Chinese citizens will increase by 2 years.
4 years compared to 2013. PM 2.
It can play a role in heart disease, stroke and lung diseases such as swelling and cancer.
Public discontent with another study published by the university in 2017 found that air pollution in northern China has shortened life expectancy by three years compared to southern China.
"We don't have a historical example of a country that can reduce air pollution so quickly.
This is remarkable, "said Michael Greenstone, an economist and director of the University of Chicago's Energy Policy Institute, on Tuesday.
By contrast, he noted that after the 1970 Clean Air Act was enacted in the United States, it took the United States more than ten years and a severe recession to achieve similar improvements in air quality.
"In the last four years, people have proved very loudly that things can be changed and can be changed quickly --
"It only needs political will," he said . "
As the public becomes increasingly dissatisfied with China's choking smog, the Communist Party of China has made clean air a top priority.
In 2013, the company launched an ambitious air pollution action plan to try to cut PM 2.
Level 5 in key areas such as northern Beijing-Hebei-
Tianjin and the Yangtze River Delta region for a quarter.
On 2014, Chinese Premier Li Keqiang declared war on pollution.
Since then, inspection teams have been deployed in major cities in North China to ensure compliance with pollution standards.
On Tuesday afternoon, the gray sky in Beijing highlighted the challenges facing China.
Five levels have soared to 270 micrograms per cubic meter, which is the 24-24 recommended by the World Health Organization-hour period.
But social costs in the capital and elsewhere have improved.
Beijing cut PM 2
Between 2013 and 35%, the 5 th level increased the life expectancy of the residents of the, and increased by 3.
The study found that three years.
As of 2015, Baoding, China's most polluted city, had reduced its pollution by 38%, an increase of four. 5 years of life.
"China as a democratic regime has not yet been put on hold, but here we have a clear example of what the public is asking for and what the government is offering," Greenstone said . ".
However, the smog war has brought social costs.
In order to clear the sky, authorities ordered thousands of polluting factories to leave the city center and displaced thousands of migrants.

The "Coal Zone" forced more than 3 million households in the surrounding area of Beijing to suddenly turn to gas or electric heating, usually removing coal-fired boilers before the new system runs.
On December, schools in Hebei province made headlines because students were frozen in class outside.
The delay in the installation of the new electric heating system means that in the faint winter sun, it is a little warmer than the cold classroom.
Greenstone says he wants to see China move toward more markets.
Based on environmental regulations.
He suggested measures like cap. and-
Trade market for particulate matter and increase pollution tax.
