What are the causes, hazards and prevention of smog caused by fireworks?

Fireworks and firecrackers will produce a large number of particles such as sulfur dioxide, nitrogen oxides, smoke and carbon particles during the discharge process, and the formed smoke cannot spread rapidly, resulting in a significant increase in PM2.5 concentration and haze weather.

Danger:

1, Harm to human body: Due to a large number of toxic and harmful small particles mixed in the smog, people will enter the respiratory tract and lungs with the air when breathing, which may lead to bronchitis, pneumonia and other diseases, and even more serious diseases.

2. Harm to work and life: Haze weather has low visibility, which has an impact on aviation, railways, shipping, highways and other transportation industries, easily leading to traffic accidents and disrupting normal work and life order. At the same time, it is corrosive to buildings, vehicles and other solid objects.

1. Do not set off or reduce fireworks and firecrackers to reduce air pollution.

2. Civilized emissions. Don't set off fireworks and firecrackers in urban areas, public places, at noon and at night when ventilation is inconvenient and diffusion is unfavorable.
