What pollution and harm do fireworks and firecrackers cause to the environment?

When setting off firecrackers, it will release a lot of harmful gases, such as sulfur dioxide (SO2), nitrogen dioxide (NO2), hydrogen sulfide (H2S), carbon monoxide (CO) and so on. After sulfur dioxide enters the atmosphere, it first reacts with water to generate sulfurous acid (H2SO4): SO2+H2O = H2SO4.

Sulfuric acid is oxidized into sulfuric acid in air: 2H2SO4+O2 = 2H2SO4. Acid rain formed in clouds (acid rain is called "death in the air") can strongly corrode buildings and industrial equipment.

Acid rain will lead to the death of trees and forests, the extinction of fish and shrimp in lakes, the destruction of soil nutrition, and the reduction or death of crops. Nitrogen dioxide can irritate eyes, nose, throat and lungs; In addition, it also forms urban photochemical smog, which affects visibility; It will form small droplets of nitric acid and acid rain.

1, causing air pollution. Fireworks and firecrackers will produce a large number of harmful gases such as sulfur dioxide, nitrogen dioxide, carbon dioxide and carbon monoxide and various metal oxide dust. Among them, sulfur dioxide and nitrogen dioxide are highly irritating and corrosive acid oxides.

Especially when it is discharged in large quantities, if it happens in windless or low-pressure weather and harmful gases cannot be dispersed for a while, it will strongly stimulate people's respiratory tract, make people cough and cause respiratory diseases such as tracheitis.

2, causing noise pollution. Setting off fireworks will bring a lot of noise, which will have a great impact on our physiology and psychology, not only damaging our hearing, but also damaging our cardiovascular system.

For example, the loud noise caused by setting off fireworks will make it difficult for the elderly to sleep, frighten patients and prevent students from studying and resting quietly. Many times, pedestrians are frightened by the sudden loud noise when they are set off. For people with heart disease, this kind of fright is likely to lead to more serious consequences.

3, bring fire or other accidents. Setting off fireworks and firecrackers can easily cause fires or accidentally blow people up, especially in urban areas, where buildings are getting higher and higher and the population is denser. Setting off fireworks at high altitude is more likely to cause fire or casualties, which directly endangers people's lives and property.

4. Waste of resources. At the same time, setting off fireworks means setting off precious resource paper (trees) and chemical raw materials (including the pollution caused by the production of these raw materials), which makes the streets and alleys full of wolves, and people let go, which makes people develop irresponsible habits.
