According to data,
there are about 2.9 billion people in the world using coal, wood, or animal waste as the main cooking fuel, and there is evidence shows that air pollution is related to cardiovascular diseases, respiratory diseases and cancer etc.
The major diseases caused by outdoor air pollution that resulted in death:
Stroke: 40%
Children acute lower respiratory infection: 3%
Lung cancer: 6%
Chronic obstructive pulmonary disease: 11%
Heart attack: 40%
People need to breathe. An adult breathes about 20,000 times a day,
inhaling air of 15 ~ 20 cubic meters.
Therefore, polluted air has direct impact on human health.
There are more than 500 kinds of volatile substances in indoor air, among which there are more than 20 kinds of carcinogen and more than 200 kinds of pathogenic viruses.
According to the statistics of China Center for Disease Control and Prevention, cases of lung cancer, leukemia, infertility, fetal abnormalities, skin cancer,
nasal cancer and throat cancer caused by indoor air pollution are common in recent years.
Moreover, children are more vulnerable than adults to the harm of indoor air pollution.
According to the news on March 26, 2014 by China News Agency in New York, WHO released a report showing the death in the world every year caused by air pollution.
According to the recent report issued by Development Research Center of State Council of China and the World Bank in Beijing jointly, the high mortality and other health problems caused by air pollution in China brought economic loss of 100 to 300 billion yuan every year.
In Southeast Asia and the western Pacific region 2.6 million people die of indoor air pollution every year.
In countries with low and middle incomes, 172 out of 100,000 people die of air pollution, which is five times as much as high-income countries.
In Southeast Asia and the western Pacific region are most affected by air pollution, and 3.3 million people die of indoor air pollution.
Raw coal desulfurization technology can remove about 40% - 60% of inorganic sulfur in coal. Give priority to low sulfur fuel, such as low-sulfur coal and natural gas, etc.; Improve fire coal technology, reducing emissions of sulfur dioxide and nitrogen oxides in the process.
The management of transport exhausts to reduce vehicle exhaust. Improve the design of engine and oil burning quality, and strengthen traffic management. Install vehicle catalytic converter to promote full fuel combustion and reduce the emissions of harmful substances.
Take public transport as far as possible, reduce exhaust pollution of vehicles, control the development of the private cars effectively, expand the scope and capability of subway transportation, use green bus (using liquefied petroleum gas and compressed gas) and other environmental-friendly vehicles.
Develop new energy sources, promote the use of natural gas, coal gas and liquefied petroleum gas gradually, choose low sulfur fuel, and desulfurization processing for heavy oil and coal, develop and utilize solar energy, hydrogen fuel, geothermal and other new energy.
In addition to decoration, plants also have functions of regulating climate, block, and filter and absorb dust and harmful gas in the atmosphere.
Implement the responsibilities for all parties. Implement responsibility appraisal for the prevention and control of atmospheric pollution, improve the monitoring system of national supervision, local regulation and unit responsibility. Improve air pollutants emission standards of cement, boiler and nonferrous industry. Regulate the release environment information.
