What are the hazards of ozone? What are the hazards of ozone？

1. What is ozone?

Ozone (chemical formula O3), also known as triatomic oxygen, is named for its smell similar to fishy smell. Ozone in nature mainly exists in the altitude of 12,000 to 35,000 meters above the earth's surface, forming an ozone layer under the action of the sun's ultraviolet rays. It is a protective layer that shields organisms on the surface of the earth from ultraviolet rays. It can absorb 90% of ultraviolet rays, is a loyal "guard" of mankind, and has an irreplaceable function for maintaining the earth's ecological environment. A small amount of ozone is produced in forests, seasides, waterfalls and after thunderstorms, with a concentration of 0.01-0.08ppm. Therefore, people feel that the air is fresh, refreshing and refreshing in the above-mentioned environment. This is because of the existence of ozone. So the English translation of "Freshair" means "fresh air". So don't feel bad smell just because it is called "ozone"!

2. Where does ozone mainly exist?

Ozone is a kind of trace gas in the earth's atmosphere. It is formed when oxygen molecules in the atmosphere are decomposed into oxygen atoms by solar radiation and high-voltage lightning, and then the oxygen atoms combine with surrounding oxygen molecules. It contains 3 oxygen atoms. More than 90% of the ozone in the atmosphere exists in the upper part of the atmosphere or in the stratosphere, 10 to 50 kilometers away from the ground. This is the atmospheric ozone layer that needs human protection. There are a small number of ozone molecules hovering near the ground, which can still have a certain effect on blocking ultraviolet rays.

3. What are the hazards of ozone

Judging from the nature of ozone, it can both help and harm people. It is not only a protective umbrella given to mankind by God, but sometimes it is like a potent poison. So far, people have reached consensus and have done a lot of work on the positive effects of ozone and what measures humans should take to protect the ozone layer. However, although people have already understood the negative effects of the ozone layer, apart from atmospheric monitoring and air pollution forecasting, there is still no real and feasible method to solve them.

The high concentration of ozone near the ground can stimulate and damage the eyes, respiratory system and other mucosal tissues, and have a negative effect on human health. Every cubic meter of ozone in the air increases by 100 micrograms, and human respiratory function will be weakened by 3%.

When ozone reaches a certain concentration, it can make people's breathing faster and chest tightness. If the concentration is further increased, it can cause accelerated pulse, fatigue, and headache.

Staying in an environment with severe ozone pollution for a long time may also damage your skin health.

Ozone pollution can also cause damage to the environment. For example, when ozone reaches a certain concentration, it will cause plant leaves to die and fall off, harm the ecological environment, and reduce crop production.

    The above is purely theoretical. At present, there have been no reports of human illness or death caused by ozone, and no reports of mass production reduction or death caused by excessive ozone concentration in animals and plants. Because in our actual life, we must have several conditions to achieve high or even high ozone concentration. One: continuous high-power ozone generator or conditions (because ozone is in water for more than 15 minutes, and in air for more than 20 minutes, it will naturally decompose (Oxygen) 2: Closed space without air convection 3: People and animals with obstacles or defects in taste and smell, because people and animals are more sensitive to the smell of ozone. Once the ozone concentration is too high, it will cause discomfort. Animals will choose to escape out of self-protection consciousness.
