Background technique

According to the monitoring data of the environmental protection department, the proportion of total air quality exceeding the standard in 74 cities in 2013 was 68.4%, and the proportion of severe and serious pollution reached 30.2%. Among them, PM2.5 exceeded the standard especially, the average over-standard rate was 68.9%, and the maximum daily average value. It reached 766 μg/m3. Malignant air pollution has seriously jeopardized human survival.

The so-called "air pollution" means that harmful substances enter the atmosphere. Particles larger than 7 microns can enter the nasal cavity, 4.7-7 micron particles can reach the throat, 3.3-4.7 micron particles can reach the main air tube, and 2.1-3.3 micron particles can reach the bronchus. - 2.1 micron particles can reach the end of the trachea, 0.65-1.1 micron particles can reach the alveoli. A phenomenon that causes harm to humans and living things. If it is not controlled and controlled, it will seriously damage the ecosystem and human living conditions.

Atmospheric environmental protection concerns the fundamental interests of the people, and it is related to the sustained and healthy development of the economy. It is related to the comprehensive construction of a well-off society and the realization of the Chinese nation's great rejuvenation of the Chinese dream. At present, the air pollution situation in China is severe. The regional atmospheric environment problems characterized by inhalable particulate matter (PM10) and fine particulate matter (PM2.5) are increasingly prominent, which impairs the health of the people and affects social harmony and stability. With the deepening of industrialization and urbanization in China, the consumption of energy resources continues to increase, and the pressure on prevention and control of atmospheric pollution continues to increase.

The Health and Family Planning Commission issued the “Work Plan for the Monitoring of Health Impacts of Air Pollution (Fog) in 2013”. It is planned to gradually establish a monitoring network covering air pollution (haze) across the country in three to five years to study the understanding of smog on population health. Hazard. On July 10, 2014, the Ministry of Environmental Protection spokesperson Tao Detian said: The Air Pollution Prevention Action Plan is called the most stringent atmospheric management plan in history and will be 17,000. 100 million investment. The plan was approved by the State Council in late June. The Minister of Environmental Protection’s renewed stance indicates that this industry-focused plan will be introduced soon. In September 2013, the State Council publicly issued the Action Plan for Air Pollution Prevention and Control in response to the increasingly smoggy weather. From the national level to the local governments, plans to control air pollution have been introduced, showing the urgency of controlling air pollution.
