Pollution is absolutely impossible. In rural areas, fireworks will only be set off on New Year's Eve and the first day of junior high school. Fireworks will produce a lot of smoke and dust, which will affect the air quality. However, the countryside is relatively empty and there is no shelter. A gust of wind will blow away pm2.5. Generally, it will be placed in front of the house in rural areas and will be cleaned up after release. Garbage will not be thrown away, so there is no land pollution or anything.
