What pollution and harm do fireworks and firecrackers cause to the environment?

When a large number of firecrackers were set off during the Spring Festival, the concentrations of sulfur dioxide and carbon monoxide in the air increased significantly, and nitrogen dioxide, sulfur dioxide and inhalable particles in the air exceeded the national standards. These pollutants exceed the standard, which means that the atmospheric environment has been polluted, and these increased pollutants are also harmful to health.

In addition, noise pollution. The explosion of fireworks and firecrackers on New Year's Eve is like thunder. Noisy people often find it difficult to fall asleep on New Year's Eve. Over the years, this seems to have become a practice in China. According to the monitoring of firecrackers pollution in Wuhan, Shanghai, Beijing and other big cities 10 during the Spring Festival, it is found that the noise in the area where firecrackers are set off is as high as 135 dB, far exceeding people's hearing range and tolerance limit.

Fireworks and firecrackers will also produce solid waste pollution. According to the sanitation department of Fuyang City, after setting off firecrackers during the Spring Festival, the amount of garbage will increase exponentially, which will increase the burden on sanitation workers during the festival. Paper scraps and smoke can be seen everywhere, which seriously affects environmental sanitation.

Setting off fireworks will also pollute the water source. The "cannon fodder" garbage should be released. If fireworks and firecrackers are set off when it rains or snows, pollutants will be discharged into the surrounding water and pollute the surrounding rivers.

Fireworks and firecrackers not only bring us joy, but also leave us a lot of toxic and harmful substances, which not only have safety hazards, but also have pollution hazards and health hazards.
