Chinese People Have A Traditional Advantage And Disadvantage Of Setting Off Firecrackers
Chinese people have a tradition of setting off firecrackers during Chinese New Year and holidays, which not only appears festive, but also helps to ward off evil spirits. This tradition has always been used. There are various types of firecrackers on the market, which are very popular. But as you enjoy the fun of the crackling sound, do you realize the harm that setting off firecrackers brings to you and everyone.
Setting off firecrackers brings many hazards to our lives, such as serious air pollution and noise pollution. There is also great danger when setting off firecrackers, especially for children who have poor safety awareness. Every year, children are injured or even endangered due to setting off firecrackers. So try to reduce the setting off of firecrackers as much as possible, and children should set them off with the accompaniment of adults.
air pollution
When setting off firecrackers, a large amount of harmful gases are released, such as sulfur dioxide (SO2), nitrogen dioxide (NO2), hydrogen sulfide (H2S), carbon monoxide (CO), etc. After sulfur dioxide enters the atmosphere, it first reacts with water to form sulfite (H2SO3)
SO2+H2O=H2SO3
Sulfite is oxidized to sulfuric acid in the air
2H2SO3+O2=2H2SO4
Forming acid rain in the clouds (known as "death in the air") can strongly corrode buildings and industrial equipment; Acid rain can lead to the death of trees and forests, the extinction of fish and shrimp in lakes, the destruction of soil nutrients, and the reduction or death of crops. And nitrogen dioxide can irritate people's eyes, nose, throat, and lungs; In addition, it also forms urban photochemical smog, affecting visibility; And it will form small droplets of nitric acid and also produce acid rain. Of course, during the process of setting off firecrackers, not only these harmful gases are produced, but also some toxic solid dust, which is also irritating to people. Items such as unburned gunpowder and remaining dust are a form of pollution. It can be seen that the harmful substances released during the setting off of firecrackers cause air pollution.
noise pollution
Setting off firecrackers not only causes air pollution, but also generates noise pollution. The noise emitted by setting off firecrackers has a significant impact on our physiology and psychology. It not only damages our hearing, but also damages our cardiovascular system; It not only affects the human nervous system, causing impatience and irritability, but also affects sleep and causes fatigue.
