Harm of setting off fireworks and firecrackers

Setting off firecrackers will not only cause air pollution, but also cause noise pollution. The noise of setting off firecrackers has a great influence on our physiology and psychology. It will not only damage our hearing, but also our cardiovascular system. It not only affects people's nervous system, makes people irritable, but also affects sleep and causes fatigue.

The deafening noise from fireworks makes it difficult for people to sleep, students can't study, TV can't watch, pedestrians are frightened, patients are scared, and heart patients are life-threatening.

According to news reports, on New Year's Eve 438+02 in 2065, Beijing dispatched more than 23,000 people to clean up fireworks and firecrackers 1423 tons, and nearly 100 vehicles were used. Sanitation workers can't reunite with their families, so they are extremely tired and can't rest.

Setting off fireworks will increase the burden on the masses, especially public funds. Every large-scale fireworks will cost hundreds to tens of millions of yuan, which is a huge waste.

The manufacture, loading and unloading and transportation of fireworks and firecrackers will explode at any time, which is a mobile bomb. The village was razed to the ground, causing countless casualties. A car full of fireworks exploded, which collapsed a bridge and caused heavy losses. We can't spend huge financial and human resources to control air pollution. On the one hand, the whole people set off firecrackers and fireworks, and government enterprises held fireworks parties to become new polluters. This year, Xi City, Lhasa City and Baoji City have formulated relevant regulations prohibiting the discharge of fireworks and firecrackers in urban areas, calling on all parts of the country to respond positively. Citizens refused to set off fireworks and firecrackers, and everyone consciously protected the environment.

Extended data:

When setting off firecrackers, it will release a lot of harmful gases, such as sulfur dioxide (SO2) and nitrogen dioxide (NO2). When sulfur dioxide enters the atmosphere, it is oxidized into sulfuric acid (SO4), which forms acid rain in the clouds (acid rain is called "death in the air"), which can strongly corrode buildings and industrial equipment. Acid rain will lead to the death of trees and forests, the extinction of fish and shrimp in lakes, the destruction of soil nutrition, and the reduction or death of crops.

Nitrogen dioxide can irritate human eyes, nose, throat and lungs; In addition, it also forms urban smog, which affects visibility; It will form small droplets of nitric acid and acid rain. Of course, in the process of setting off firecrackers, not only these two kinds of harmful gases are produced, but also unburned gunpowder and residual dust, all of which are a kind of pollution. It can be seen that the harmful substances released by firecrackers pollute the air.

It may cause permanent damage to the elderly and people who set off fireworks at close range-deafness.

Polluting the air and setting off fireworks and firecrackers will produce a lot of harmful gases such as sulfur dioxide, nitrogen dioxide and carbon monoxide, causing respiratory diseases such as tracheitis and acid rain formed in the air, resulting in forest death and crop yield reduction or death.
