Harm of discharge

Generally, fireworks will release more air pollutants, such as SO2, NO, NO2 and dust, which will cause environmental problems such as acid rain. It is understood that fireworks will produce gases such as sulfur dioxide, nitric oxide and nitrogen dioxide. These poisonous and harmful gases are invisible "killers" When the smoke is filled, these gases will do some damage to the respiratory system and nervous system, stimulate the eyes, and some will contribute to the occurrence or development of some chronic diseases.

Fireworks and firecrackers not only bring embarrassment to urban sanitation, but also bring security risks. Because many people set off firecrackers everywhere, they had to be cleaned up by sanitation workers the next day. Once the flame is not extinguished, under the condition of long-term drought in the northern region, it is easy to ignite dry trees and grass and cause fires. If you don't pay attention to personal safety when using it, especially some naughty children, it is easy to endanger the life safety of people around you, and even cause problems such as explosion and fire.
