What are the dangers of ozone ? In the past, especially ordinary people who did not have such a background, people usually equated blue sky with good air. They thought that blue sky and white clouds should mean good air quality. In the past, they often paid special attention to haze, PM2.5. But in fact, when the sky is blue, we may often ignore another pollutant, which is today’s protagonist, ozone.

At this time, some people will say, before we always said that we should protect the ozone layer, why is ozone bad again? Therefore, before talking about the harm of ozone, must clearly distinguish between "good" ozone and "bad" ozone.

The ozone in the stratosphere that is relatively far away from us is good ozone, which is what we usually call the ozone that protects the ozone layer. The ozone layer absorbs solar radiation. Without the protection of this ozone layer, we humans will face survival hazards. For example, the thinning of the ozone layer will increase the incidence of human skin cancer , so we must protect this ozone layer and have been doing so. .

Near-ground ozone, ozone close to us is not good. When the concentration of ozone near the ground is relatively high, it will cause a series of negative health effects on people , The World Health Organization has proposed a concentration value level , 200 micrograms/cubic meter , when it exceeds this, there will be significant health hazards, including damage to the nerve center and respiratory system. There are many symptoms, such as coughing, nose discomfort, and even mucous membranes in the eyes and other tissues when the concentration is high. Parts may feel irritated, especially for the elderly, children, pregnant women, or those who work outdoors for a long time. These are some people who are very sensitive to ozone.

So if your family members or people around you have such a situation, you must remind them to pay attention to ozone pollution. How to pay attention to

? We can look at the concentration of , or we can look at AQI which is the air quality index , because it usually represents the most serious pollutants.

So if the ozone pollution is serious that day, it is the most severe, and the AQI represents the ozone pollution level. Therefore, paying attention to the air quality index, rather than just looking at the blue sky, is more helpful for our health protection.

In addition, ozone can also cause some harm to the environment. When we released the event notice, a friend asked this question. Let's answer it together at the end.
