Dust pollution in Beijing contains deadly poison

Analysis of the Chinese Academy of Sciences showed that the smog that struck Beijing and its northern provinces last month contained a large amount of toxic chemicals. In the middle of it, a new wave of smogy dust covered the area.

Information published by China's Global Times. Accordingly, dense dust clouds swarm down the northern cities of the country this past January, containing a lot of toxic chemicals that appeared in world-famous polluted haze: the cloud Giant pollution in London in 1952, which was created mainly by coal burning, causing nearly 12,000 deaths, and the photochemical cloud appeared in Los Angeles, USA over the last century.

There are also many other toxins such as chemical dust, a common pollutant in China and a large amount of nitrogen-containing organic compounds - the main component of the photochemical haze, which is generated by The reaction between sunlight and dust from vehicles and industrial dust and smoke, the report of the Chinese Academy of Sciences (CAS) announced on February 16 said.

Photochemical cloudiness can lead to heart, lung disease, eye irritation and respiratory problems.

The results of the analysis were published amid warnings of a new wave of cloud of dust and pollution that began pouring into Beijing, Tianjin and Hubei and Hunan provinces on the morning of February 17, disrupting the traffic. Highways as well as flights.

At 8 am on February 18, air quality monitoring devices in five different areas in Shijiazhuang City, the capital of Hubei Province, showed extremely high levels of pollution. Meanwhile, the Beijing Environmental Monitoring Center said moderate or severe air pollution levels were recorded in many parts of the city. The view here in the early morning fell below 500m.

According to CAS, the main reason for the cloud of pollution is due to the absence of wind while the amount of suspended dust, air emissions pollutes and the steam in the air increases. According to the institute's report, about 25% of toxic dust particles are less than 2.5 micro meters (PM 2.5) derived from the exhaust smoke of vehicles. 40% of other PM 2.5 coming from pollutants is blown into Beijing from other areas as well as coal burning here.

Lü Daren, a scholar at CAS's Institute of Atmospheric Physics, affirmed that the main cause of pollutant emissions is from human activity.
