What are the main causes 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) Life stove and heating boiler:

A large number of civil stoves and heating boilers in cities need to consume a large amount of coal, and a large amount of dust, sulfur dioxide, carbon monoxide and other harmful substances are 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 modern times, and the exhaust gases from 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.

What are the causes of air pollution.

There are three main causes of air pollution:

2. Domestic stoves and heating boilers: A large number of civil living 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 when heating in winter, it often fills polluted areas with smoke.

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.

Dear, the main causes of air pollution are as follows:1Industrial and transportation emissions, exhaust gases and exhaust gases emitted by factories and automobiles contain a large number of harmful gases, such as carbon dioxide, carbon monoxide, nitrogen oxides, sulfides, etc., which will pollute the air.

2.The combustion of fossil fuels, such as coal, oil, natural gas, etc., will produce harmful gases such as carbon dioxide, increase the amount of greenhouse gases in the atmosphere, and lead to global warming and climate change. 3.

Building construction and decoration, building construction and interior decoration will produce some pollutants, such as formaldehyde, ammonia, etc., which may have an impact on indoor air quality. 4.Rent in agriculture and animal husbandry, the use of fertilizers and pesticides, and the excrement of livestock and poultry all contribute to air pollution.

5.Natural factors, such as sandstorms, volcanic eruptions, and forest fires, will also pollute the atmospheric environment.

Scientific studies have confirmed that the main cause of modern air pollution is the large amount of exhaust gases released from industrial production. Due to the large consumption of fuels such as coal and oil, the increase in the content of toxic and harmful impurities such as sulfur dioxide, suspended particulate matter, nitrogen oxides, and carbon monoxide in the air will bring catastrophic harm to human beings. In December 1952, the London smog incident killed about 4,000 more people in four days than at the same time in normal years.

Within a week of the event, the number of deaths in patients with bronchitis, coronary heart disease, tuberculosis and heart asthenia was multiple, double, double and double the number of deaths of the same type in the week before the event, respectively. Mortality rates in patients with pneumonia, lung cancer, influenza and other respiratory illnesses have increased exponentially.

Oxygen in the air is one of the important substances that human beings rely on for survival. Human beings should keep the air clean, pure and fresh, and only in a fresh atmosphere can they work, study and live happily.

There are four main aspects of air pollution caused by industrial emissions, domestic stove fumes, transportation emissions, and smoke from forest fires.

What are the causes of air pollution.

1. Industry: Industrial production emits harmful gases to pollute the air.

2. Transportation: The exhaust gas emitted by various transportation vehicles mainly includes carbon monoxide, sulfur dioxide, nitrogen oxides and hydrocarbons.

3. Hail oak smoke from forest fires.

4. Combustion of waste and garbage: After the combustion of waste and garbage, toxic gases carbon monoxide and nitrogen oxides are also emitted, which will pollute the air and endanger human health.

Therefore, everyone should travel in an environmentally friendly manner, reduce the number of self-driving trips, and advocate commuting by bus and subway. Planting green plants can purify the air.
