Shanghai Disneyland set off fireworks jokes.

I believe everyone has seen the fireworks show in Marvel comics and the news that Shanghai Disneyland has caused heated discussion. Why is it forbidden to set off fireworks everywhere now? The prohibition of fireworks is echoed by the state, because fireworks are harmful and dangerous. As the most traditional and oldest festival in China, people will set off fireworks to celebrate the Spring Festival, which has become an indispensable thing for people. There is also a reason why the country bans fireworks. According to experts, through the analysis of monitoring data, it is found that both PM2.5 and PM 10 have increased by more than 50% than usual. From the data here, we can see the harm of fireworks to the air.

First, setting off fireworks will affect air quality and pose a certain threat to air quality.

I believe everyone has seen fireworks. Fireworks are blown up in the sky, and some components of its explosion will have a certain impact on air quality. After the state banned the sale and discharge of fireworks and firecrackers, the air quality improved obviously. The average concentrations of PM2.5 and SO2 decreased significantly year-on-year. Compared with the situation that the air quality in some surrounding cities has obviously deteriorated due to the discharge of fireworks and firecrackers, the effect of banning burning and discharging is also very obvious, which has also been recognized and praised by many people. So there is a reason why fireworks are forbidden.

Second, setting off fireworks also has a certain impact on human health.

The main components of fireworks contain carbon, nitrogen, sulfur and other components, and some harmful and toxic gases will be produced after fireworks are set off. For example: carbon monoxide, nitrogen dioxide and sulfur dioxide. It not only contains these toxic gases, but also contains a lot of dust. However, these gases have irritating smell and dust, which will do great harm to people's respiratory system, thus increasing the probability of respiratory diseases. Therefore, setting off fireworks does have many disadvantages, so we should pay attention to this problem and try not to set off fireworks as much as possible, which is good for us and everyone.
