1, producing a large number of toxic smoke particles to pollute the air.
When fireworks and firecrackers are set off, a series of chemical reactions will occur in the chemical substances in firecrackers, releasing a large number of PM 10, PM2.5, carbon monoxide, sulfur dioxide, sulfur trioxide, nitrogen oxides and various metal and nonmetal oxides, and producing a large number of smoke particles, which will seriously pollute the air, and PM2.5 will seriously exceed the standard by dozens of times, causing extremely serious pollution.
2. Acid rain is harmful to the formation of buildings
Fireworks and firecrackers release a large number of harmful acidic gases, such as sulfur dioxide and nitrogen dioxide, which enter the atmosphere and form acid rain in the clouds after oxidation, which corrodes buildings and industrial equipment. In addition, the powder and residue produced by fireworks and firecrackers contain arsenic (the main component of arsenic), which is washed by rain and flows into sewers to pollute rivers, leading to the death or even extinction of fish and shrimp.
3. It is noisy and easy to cause fire.
The loud noise caused by setting off fireworks can easily affect the rest of the elderly and children, especially for people with heart disease, which is likely to lead to very serious consequences. . There are cases of severe hearing loss, explosive deafness and hearing impairment caused by setting off firecrackers in China almost every year. Moreover, once it is improperly operated, it is easy to cause a fire and endanger personal and property safety.
4. Produce a lot of garbage
A large amount of garbage produced by setting off fireworks and firecrackers has brought a serious burden to sanitation workers. Taking Beijing as an example, it is reported that on the New Year's Eve of 438+02 in 2065, Beijing dispatched more than 23,000 people to clean up fireworks and firecrackers 1.423 tons and used nearly 100 vehicles.
