Lighting firecrackers will release a large number of harmful gases, such as: sulfur dioxide (SO2), nitrogen dioxide (NO2), hydrogen sulfide (H2S), carbon monoxide (CO) and so on. Sulfur dioxide into the atmosphere, the first and water reaction to generate sulfurous acid (H2SO3): SO2 + H2O = H2SO3
Sulfurous acid in the air is oxidized to sulfuric acid: 2H2SO3 + O2 = 2H2SO4. in the clouds to form acid rain (acid rain is known as the "air of death"), can be strongly corroded buildings and industrial equipment. It can strongly corrode buildings and industrial equipment.
Acid rain can lead to the death of trees and forests, the disappearance of fish and shrimp in lakes, and the destruction of soil nutrients, resulting in reduced crop yields or death. And nitrogen dioxide irritates the eyes, nose, throat and lungs; it also forms urban photochemical smog, which affects visibility; and it forms small droplets of nitric acid, which also produces acid rain.
1, causing air pollution combustion. Fireworks at the same time will produce a large number of sulfur dioxide, nitrogen dioxide, carbon dioxide, carbon monoxide and many other harmful gases and various metal oxides of dust. Among them, sulfur dioxide, nitrogen dioxide is irritating and corrosive acidic oxides.
Particularly when a large number of fire, if the weather coincides with no wind or low pressure, the harmful gases can not be dispersed for a moment, it will be a strong stimulation of the respiratory tract, so that the person coughing, causing bronchitis and other respiratory diseases.
2, causing noise pollution combustion. Fireworks will bring great noise, which has a great impact on our physiology and psychology, not only will damage our hearing, but also damage the human cardiovascular system.
For example, the fireworks fireworks produce a huge noise, will make the old difficult to sleep, the patient fear, students can not be quiet study, rest. In many cases, the sudden loud noise of the fireworks startles pedestrians, and for people with heart disease, the shock is likely to lead to even more serious consequences.
3, bring fire or other accidents. Fireworks are very easy to cause fire, or accidentally bombed people, especially in urban areas, buildings are getting higher and higher, relatively densely populated, high-altitude fireworks and other fireworks are more likely to cause fires or casualties, directly endangering people's lives and property safety.
4, bring the waste of resources. Fireworks at the same time, means that the valuable resources paper (trees), chemical raw materials (including the production of these raw materials caused by pollution) are burning away, so that the streets and alleys are full of wolf traces, put away, so that people develop a habit of irresponsibility.
