Do fireworks pollute the air after they are ignited?

The main ingredient of traditional fireworks is black powder Black powder is composed of sulfur, charcoal powder, potassium nitrate, potassium chlorate and other components, so after combustion, air pollutants such as sulfur dioxide, carbon monoxide, and nitrogen dioxide will be generated; At present, most of the fireworks are environmentally friendly, which will reduce the sulfur, charcoal powder, and potassium nitrate caused by the combustion of black powder; While fireworks bring joy to people, they also cause environmental pollution

So the answer is: sulfur dioxide (carbon monoxide, nitrogen dioxide, etc.); sulfur (charcoal powder, potassium nitrate); It can add to the festive atmosphere, but it can produce substances that pollute the environment when burned

Pollutants such as sulfur dioxide, carbon monoxide, and other pollutants are produced when fireworks are ignited.

Setting off fireworks is a great thing for traditional festivals. However, there are regulations in some places that cannot be used. Fireworks.

There should be carbon dioxide, sulfur dioxide and so on. Personal thoughts.

1. Carbon monoxide.

This is only an important reason why the smoke directly kills people when there is a fire, and the smoke produces a large amount of carbon monoxide, which will cause carbon monoxide poisoning and death when the human body sucks it into the lungs.

2. Carbon dioxide.

The smoke from the fire also contains a large amount of carbon dioxide, which can be fatal if the content of carbon dioxide in the air is relatively high.

3. Highly toxic gas.

The smoke emitted from a fire must contain all kinds of toxic gases, because in the process of combustion, those chemicals will release toxic gases, which is also a deadly gas leakage.

The deadliest gas in a fire is carbon monoxide. There are also some toxic gases such as sulfur.

There are many gases produced by combustion, mainly carbon dioxide, carbon monoxide, nitrogen oxides, cyanide, sulfur oxides, water vapor 2, smoke does not only contain gases, but also some liquid particles, some solid suspended particles...

The smoke of the fire kills people.

The main reason is that it consumes a lot of oxygen and dies of suffocation due to lack of oxygen.

If you insist on talking about toxic substances.

I think it's carbon monoxide that is completely produced without combustion.

Mainly carbon monoxide, nitrogen oxides, cyanide, sulfur oxides, etc.

Fireworks are heavily polluted. The polluting gas of fireworks and firecrackers is much more serious than exhaust pollution, car exhaust is nothing more than nitrogen oxides, sulfur oxides, incomplete combustion gases, fireworks and firecrackers are a variety of chemical raw materials, like potassium nitrate, potassium perchlorate, potassium chlorate, barium nitrate, etc., there are more polluting gases.

Settlement of Fireworks Pollution:Disney couldn't completely cancel the fireworks display, and the residents did not agree to the usual fireworks, and later after many negotiations, a compromise approach was adopted - on the one hand, Disney used fireworks to purchase better quality fireworks to reduce pollution; On the other hand, while setting off fireworks, fountains, lights, and water mist are used to set off, so as to greatly reduce the amount of fireworks and minimize pollution.
