What are the hazards of haze?
1, induced respiratory disease. Haze composition is very complex, the size of hundreds of particles, these particles through the body to breathe, into the respiratory tract, can cause tracheitis, asthma and other respiratory diseases.
2, triggering cardiovascular disease. Fog and haze weather, low oxygen content of the air, will make the heart beat faster, people chest tightness, shortness of breath. Especially for the elderly more harmful.
3, triggering a variety of bacterial diseases. Because the fog and haze weather the sun shines less than the earth, or the sun is weak. This will make the surface of bacteria and viruses rapid propagation of microorganisms, causing allergies and other diseases.
4, increased risk of cancer. As we all know, smokers suffering from lung cancer is 60% higher than the average person, while the haze contains more harmful particles, so smog is more likely to cause cancer than smoking.
5, people feel depressed and irritable. The mood of the people is easily affected by the weather. The smoggy weather is gloomy and gloomy, the air is dirty and the mood of the people can also become depressed. The mood is agitated and the vitality of doing things is lacking.
6, prone to traffic accidents. Fog and haze weather will reduce the visibility, serious can only see the distance of a few meters. On the road pedestrians, vehicles have a great security risk, very dangerous.
According to a study published by Berkeley Earth, an independent foreign research institution, 1.6 million people die from PM2.5 related major pollutants each year in China, accounting for 17% of the total deaths. In other words, on average, 4,000 people die of air pollution in China each day.

When will China cure the smog?
He Kebin (Academician of Chinese Academy of Engineering, Dean of School of Environment, Tsinghua University): If Beijing-Tianjin-Hebei integration progresses smoothly and can make breakthroughs in energy structure and industrial structure, emission reduction will be accelerated. However, the concentration of PM2.5 in Beijing and other places should be reduced to 35 micrograms / cubic meter, which takes 10 to 15 years to reach after 2025.
Chang Jiwen (member of the Committee of Experts on Environment and Health of the Chinese Society of Environmental Science): At present, the annual average PM2.5 concentration in Beijing, Tianjin and Hebei Provinces is decreasing, but the concentration of PM2.5 precursors is still 10 times that of the developed countries about. In general, the emission of major pollutants in China will generally be at a turning point that crosses the peak and enters the downward channel in the next 10 years. By the end of the "13th Five-Year Plan" and the "middle of the 14th Five-Year Plan", the total discharge of major pollutants The inflection point may come full time.
In short, it is formed through the accumulation of decades of development and can not be eradicated in a year or two.
