What exactly are the causes of air pollution?

1) Industry: Industry is an important part of air pollution. There are many types of pollutants emitted into the atmosphere by industry, and their properties are complex, including soot, sulfur oxides, nitrogen oxides, organic compounds, halides, carbon compounds, etc. Some of them are soot, and some are gases.

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. Especially in winter, when heating, it often fills the polluted area with smoke and chokes people's cough, which is also a source of pollution that cannot be ignored.

3) Transportation: Automobiles, trains, airplanes, and ships are the main means of transportation in contemporary times, and the exhaust gases produced by burning coal or oil are also important pollutants. In particular, the number of cars in the city is large and concentrated, and the pollutants emitted can directly invade people's respiratory organs, which is very serious to the air pollution of the city, and has become one of the main sources of air pollution in the big city.

The exhaust gases emitted by automobiles mainly include carbon monoxide, sulfur dioxide, nitrogen oxides and hydrocarbons, and the first three substances are very harmful.

Depending on the classification criteria, air pollution can be classified into four groups.

1. Divided according to pollution sources:

1.Natural air pollution: refers to air pollution caused by natural causes.

2.Anthropogenic air pollution: refers to air pollution caused by human-caused causes.

2. According to the scope of pollution:

1.Localized pollution: refers to the widespread pollution of a small unit or location.

2.Regional pollution: refers to the endemic pollution of a city or region.

3.Widespread pollution: refers to the spread of pollution in the surrounding area due to large-scale pollution in a certain area.

4.Global pollution: refers to large-scale pollution worldwide.

Since there is no unified normative scope standard, this method of division by scope is not applicable to some countries or places with large or small land areas, so we also have two ways of dividing them.

This is because there are two reasons for air pollution in India, on the one hand, the large amount of smoke produced by farmers burning straw, and on the other hand, the large amount of exhaust emissions caused by industrial production. The above facts show that India is taking the path of polluting first and cleaning up later, and this path has been proven to be unworkable by many countries, and will only make one country pay more for protecting the ecological environment.

Causes of air pollution: 1. Pollutants emitted into the atmosphere by industry; 2. Pollution of dust, sulfur dioxide and other harmful substances released during the combustion process of living stoves and heating boilers; 3. Pollutants emitted by automobiles, trains, airplanes, and ships are the main causes of air pollution.

Population growth, environmental pollution, exhaust emissions, improper disposal of household waste.

Emissions from vehicle exhaust and factory exhaust, smog from deforestation, smog from deforestation, straw burning and smog from forest fires are the causes of air pollution.

Air pollution is caused by many causes. The most important thing is the exhaust gas pollution generated by industrial production near the city, nowadays, some local environmental protection departments turn a blind eye to air pollution, never say that they take the initiative to go out to check, plus a certain interest relationship, environmental protection problems have not been really solved, secondly, car exhaust is also an important reason, the oil is not qualified, and the increasing number of vehicles leads to serious air pollution in the city. Again, there are certain reasons for burning rice stalks and burning coal for heating, but the impact of these on the city is basically negligible, because only the countryside will do this, and the air in the countryside is always better than that in the city, indicating that the source of urban pollution comes from near the city, but some people put the responsibility on the farmers, and actually made a law, I can only hehe!

Finally, the fumes from stir-frying are also one of the sources of pollution.

In general, urban air pollution sources include domestic pollution sources and production pollution sources. The sources of domestic pollution include the combustion of coal by residents, the smoke and dust produced by garbage incineration, and the emission of motor vehicle exhaust, which will lead to air pollution, of which motor vehicle exhaust is the main source of urban air pollution, and industrial waste gas, construction site dust and industrial coal emission are all pollution caused by the production field. These pollutants include sulfur dioxide, carbon monoxide, nitrogen dioxide, respirable particulate matter, and ozone, among others.

People may face the threat of diseases caused by excessive inhalation of these pollutants, so in the prevention and control measures of air pollution, it is necessary to strengthen the monitoring of air quality and actively improve the environmental situation, for example, we can use clean energy as much as possible, participate in afforestation, grass planting, etc., and strive to build a green ecological environment.

The source of indoor air pollution lies in decoration. Decoration materials are originally the source of formaldehyde pollution. All kinds of decoration materials will have different degrees of formaldehyde volatilization due to different materials, and the concentration of formaldehyde and other harmful substances in the air determines the quality of the air.

To protect the environment, start from the small things, start with us.

There are many reasons for this, so this happens because there are many cars that are still emitting exhaust fumes. And it is also related to people's destruction of the environment, and it is also related to the weather, because sometimes the weather is very bad, and there will often be strong winds, so this will cause very serious air pollution. And it is also related to industry, because there are factories that emit pollutants every day.

Therefore, this also warns us that we must protect the environment in our daily life and not bring unnecessary trouble to society.

Air pollution is mainly due to municipal odor and industrial exhaust gas, as well as exhaust pollution from various means of transportation, decoration exhaust gas, laboratory exhaust gas and other public space pollution.

Among them, the generation of municipal odor mainly comes from the water supply and drainage units, sewage treatment units or garbage disposal units in municipal projects, including:Lifting pumping stationStormwater pumping stationsSewage treatment plantsGarbage transfer stationswithGarbage treatment plantsWait; The generation of industrial waste gas mainly comes from the exhaust gas emission of various industrial production industries, including:Chemical industryIncineration (metallurgical) industryElectronics industryFood industryPharmaceutical industryFeed industryAquaculture industryTextile industryPaper industrypackaging industryPrinting and dyeing industryWait a minute.
