What is the destruction of China s atmospheric resources?

Hello! Examples are: acid rain, greenhouse effect, destruction of the ozone layer, industrial dust, smog, etc.

It is customary to refer to the substances in the earth's atmosphere that can be used by people, their energy and the space they occupy, including air, water, dust and electromagnetic waves propagating in them.

The causes of air pollution in the atmosphere include both natural and man-made factors, especially man-made factors, such as industrial exhaust gases, combustion, automobile exhaust and nuclear emissions.

First, the causes of air pollution:

1) Industry: It is an important part of air pollution, and there are many kinds of pollutants in the atmosphere that are discharged into the atmosphere by industrial rulers, and their properties are complex, including soot, sulfur oxides, nitrogen oxides, organic compounds, halides, carbon compounds, etc.

2) Stoves and heating boilers: A large number of civil stoves and heating boilers in the city need to consume a large amount of coal, and a large amount of dust, sulfur dioxide, carbon monoxide and other harmful substances will be released during the combustion process of coal to pollute the atmosphere.

3) Transportation: Cars, trains, airplanes, and ships are the main means of transportation in contemporary times, and the exhaust gas produced by burning coal or oil is also an important pollutant, becoming one of the main sources of air pollution in large cities. The exhaust gases emitted by automobiles mainly include carbon monoxide, sulfur dioxide, nitrogen oxides and hydrocarbons, and the first three substances are very harmful.

Second, air pollution control measures:

Corresponding pollutants to find the source of pollution, from the source of control; improved technologies (e.g. desulphurization and dust removal technologies); Planting trees, increasing urban green coverage, increasing the use of new energy, and so on.

Air pollution data from the U.S. Environmental Protection Agency.

According to air pollution statistics provided by the U.S. Environmental Protection Agency, since the introduction of clean air in the United States.

Since the implementation of the Gas Act, air quality across the United States has continued to improve. It is understood that the U.S. Clean Air Act points out that carbon monoxide, ground-level ozone, lead, and dioxide must be monitored in real time across the country.

Six major air pollutants, including nitrogen, particulate matter, and sulphur dioxide. In addition, the EPA has gradually included the monitoring of a large number of secondary pollutants in its scope of supervision.

Carbon monoxide. Statistics from the EPA show that from 2000 to 2010, the amount of carbon monoxide in air pollutants in the United States has decreased by 51%. Behind this decline, some estimate that 600,000 tons of carbon monoxide is emitted into the air in the United States every day.

Ground-level ozone pollution.

According to trends in air quality, ground-level ozone levels decreased by 11 percent in total U.S. air from 2000 to 2010. It is also the smallest reduction in ground-level ozone in the world since 1980.

Air lead pollution.

Airborne lead is one of the most dangerous industrial compounds. According to Air Quality Trends, the proportion of lead-polluted air in the United States has gradually decreased, the composition of major pollutants is decreasing, and the prevalence of diseases caused by lead pollution is also decreasing. It is reported that from 1980 to 2010.

Lead contamination levels have dropped by 89 percent.

Nitrogen dioxide. Nitrogen dioxide is mainly produced in household combustion appliances and is a relatively common corrosive pollutant, which has a huge impact on people living in the family. Thus, the EPA advises people that they can be at home.

Nitrogen dioxide indicators are installed in water heaters to remind you to take measures to deal with nitrogen dioxide pollutants at any time. Overall, nitrogen dioxide levels in the U.S. are now down 52 percent from 2010. It is reported that the actual content of nitrogen dioxide is actually lower than the level stipulated in the Circumstances Act.

When monitoring particulate pollution, the Particulate Matter Environmental Protection Agency focuses on two different types of particulate matter: those with ratios smaller than microns and those larger than 10 microns. It is reported that from 1990 to 2010, particulate pollution smaller than 10 microns has fallen by 38%, while particulate pollution smaller than microns has decreased by 27%.

Until now, the EPA has continued to monitor.

Sulfur dioxide. Sulphur dioxide is mainly released by the combustion of fuel in automobiles and power plants. From the perspective of air quality development trends, the level of sulfur dioxide has been gradually declining since 2000, and has dropped by 50% so far. EPA's tracking of sulphur dioxide levels shows that from 1980 to 2010, sulphur dioxide levels fell by 83 percent.

Overall sulphur dioxide emissions are now the same as they were a decade ago. This is what I took from the air pollution control channel of the e-fan network, you can see if it meets your needs.

Hope it helps.
