The products of air pollution, the main pollutants in the air, what each produces

Air pollution is mainly caused by toxic gases produced by pollution sources, and the most important pollution sources at present include: industrial pollution, traffic pollution and domestic pollution. Industrial pollution is an important part of air pollution, because factories, especially power plants, metallurgical plants, etc., have a large demand for coal and other combustions, and there are many pollutants emitted into the air, mainly including toxic gases such as nitric oxide, nitrogen dioxide, soot, sulfides, etc., which have not been fully combusted.

With the increasing number of private cars in recent years, the impact of transportation on air quality has also become one of the main sources of pollution. Major means of transportation such as automobiles, airplanes, trains, and ships are currently mostly fueled by oil and coal, and the polluting gases they produce are also not to be underestimated. From a medical point of view, these air pollution are the main killers of respiratory diseases, in addition, air pollution will also have a great impact on the climate and weather, resulting in an increase in ozone, a decrease in solar radiation, a shortage of nutrients needed for plant growth, and a slowdown in pollution inhibition.

In addition, the problem of carbon dioxide, the greenhouse gas emitted by pollution, is an international problem that has been difficult to solve until now.

As a member of the world, we should be responsible for the world, responsible for future generations, take care of every side of the air around us, advocate low-carbon life, enterprises as large individuals should also lead by example, save energy and reduce emissions, and do what we can for our common home.

If you look at the second half of this article, it should be what you want, and I hope it can help you.

Smog, acid rain, global warming.

1. Carbon monoxide: It is a colorless, tasteless, odorless flammable and toxic gas, which is the product of incomplete combustion of carbon-containing fuels, and the problem of carbon monoxide pollution is more prominent in high-altitude cities or cold environments.

2. Nitrogen oxides: mainly refer to nitric oxide (NO) and nitrogen dioxide (NO2), most of which are used in the high-temperature combustion process of fossil fuels. Nitric oxide is relatively harmless, but it is quickly oxidized by ozone in the air to become nitrogen dioxide.

3. Ozone: It is a representative pollutant of photochemical smog, which is mainly formed and enriched by nitrogen oxides and hydrocarbons in the air through a series of complex atmospheric chemical reactions under strong sunlight.

4. Hydrocarbons: Hydrocarbons in nature are mainly produced by the decomposition of organisms, such as methane, ethylene, etc.

1) Industry: There are many types of industrial air pollutants, 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: Coal will release a large amount of dust, sulfur dioxide, carbon monoxide, and other harmful substances to pollute the atmosphere during the combustion process.

3) Transportation: Cars, trains, airplanes, etc., have serious air pollution in cities and have become 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.

Answer: caHydrogen is burned in the air to produce water, which is pollution-free;

b.The carbon is burned and burned in oxygen, and the oxygen is sufficient, carbon dioxide gas is generated, and there is no pollution;

c.Sulfur is burned in oxygen to produce sulfur dioxide gas, which is the main gas for the formation of acid rain and pollutes the air;

d.Methane is burned in the air to produce carbon dioxide gas and water, which is pollution-free;

So the answer is c.
