The city of Beijing, frequently criticized for its high levels of air pollution, recorded an average index of 89.5 micrograms of PM 2.5 particles per cubic meter of air in 2013, more than double the 35 that national authorities consider the normal and safe standard.

According to the official Xinhua agency, the figure means that Beijing “fails to meet national standards” and indicates that “the capital, plagued by pollution, faces great challenges.”

are those particles in the air smaller than 2.5 microns Europe Cell Phone Number List in diameter, the most dangerous, since due to their size they can reach the lungs and affect the human respiratory system.

Above 100, the particle meter indicates contamination in the air, although in 2013 there were many days in which Beijing had levels above 300, which are considered maximum danger and in which it is recommended not to go out. (There were even days when the indicator exceeded 1,000 points).

According to figures now provided by the Beijing Environmental Control Center, the city suffered 58 days of serious pollution, compared to 178 in which the air was not contaminated.



Reports from the Chinese Academy of Sciences made public this week affirm that the main factor of air pollution in the capital is industry, compared to previous theories that pointed to traffic as the main "culprit" of Beijing's smog.Residents of Beijing and nearby cities appear to have become accustomed to the smog, but those residing in the Yangtze River delta to the south have not.

In the past, Beijing was known as the smog capital of China.

Now, China has a smog belt stretching from Beijing to Shanghai. Construction of a high-speed railway line connecting Beijing to Shanghai took a little over three months to complete, but it was in less than two years that smog spread from the Chinese capital to Shanghai. At this rate, smog will cover the entire country in even less time.
