Ozone is the main component of the atmosphere, and poor air quality refers to the excessive content of such fine particles in the air as in the air, but when the air quality is not good, the ozone concentration will not be greatly affected, and the main impact is the content.

The amount of ozone in the atmosphere is only 1 part per 100 million, but in the stratosphere, 20 to 30 km above the ground, there is an ozone layer, which contains 1/100,000 of the total air at this altitude. Although the ozone content of the ozone layer is extremely small, it has a very strong ultraviolet absorption function, which can absorb the harmful part of the sun's ultraviolet rays (UV B). Because the ozone layer effectively blocks the invasion of ultraviolet rays from the sun, it enables human beings and all kinds of life on the earth to exist, reproduce and develop.
Ozone layer depletion and the "ozone hole" in the stratosphere of the atmosphere 20 30 km above the ground is the concentrated zone of ozone, the ozone layer is the best umbrella for the earth, it absorbs most of the ultraviolet rays from the sun. However, in the past 20 years, scientific research and atmospheric observations have found that the ozone layer in the Antarctic atmosphere has been thinning every spring, and in fact there is an ozone "hole" in the polar atmosphere.
In 1984, British scientists discovered for the first time an ozone hole over Antarctica. In 1985, the U.S. meteorological satellite Nimbus-7 measured the ozone hole. It was further confirmed after several years of continuous observation.
According to NASA, total ozone measurements recorded on NASA's Nimbus 7 satellite indicate that the ozone hole over Antarctica has been expanding in recent years. Currently, ozone is decreasing not only in the Antarctic, but also over the Arctic. This is shown by the measurements carried out by the joint investigation team of the NASA and the European Ozone Layer Survey.

Ozone is a pollutant in the air.
Ozone is an allotropic form of oxygen that has a fishy smell and is a pale blue gas. Ozone is extremely oxidizing, and it is an oxidizing agent stronger than oxygen, which can undergo oxidation reactions at relatively low temperatures. Ozone refers to the amount of ozone in the air close to the ground level, which will have a certain impact on the environment and cause the same damage to human health.
The use of ozone is still relatively wide, like ozone disinfection technology, in the disinfection, the sterilization efficiency of ozone disinfection technology is relatively high, which can remove odors, and there will be no residue or pollution. When in a relatively sealed environment, the problem of disinfection dead ends in ultraviolet sterilization is overcome, and the disinfection technology can achieve the problem of disinfection without dead ends.

The first thing to look at is the air quality index. Before going out for a run, look at the local air quality index, and if it's over 150, it's best to run on a treadmill. If you have to run outside, be wary of shortness of breath and coughing. >>>More

Hello! Traditional Chinese medicine believes that when the air is dirty, people are prone to heat and dryness, and cause gastrointestinal discomfort. At this time, the diet should be as light as possible, eat less spicy and greasy food, drink more water, and rest more to improve immunity. >>>More
It is very beneficial to open the window for ventilation in daily life, first of all, you can increase the oxygen in the room, if the window is closed for a long time, then the room is in a closed space, and the human body will release some carbon dioxide. >>>More
