The thick hazardous smog which routinely blankets the streets in Beijing has been brought to discussion over and over again. Research shows that some particles of the smog in China are nano particles which can enter the pulmonary alveoli, blood and nerve system, causing long-term synthetical harm to human body. Besides, there are various constituents in the smog produced not only by industrial emission and vehicle exhaust, but also by the secondary chemical reactions from the pollutant. In order to improve the air quality, the government has put forward ten measures including reducing the pollution sources, speeding up the technological upgrading of the factories, shutting down high pollution factories, etc. Although minor effects can be seen, there is still a long way to go.
