High concentrations of ozone near the ground can irritate and damage mucosal tissues such as the eyes and respiratory system, and have negative effects on human health. For every 100 micrograms of ozone content per cubic meter in the air, human respiratory function will decline. Weaken 3.
When ozone reaches a certain concentration, it can cause accelerated breathing and chest tightness. If the concentration is further increased, it can cause accelerated pulse, fatigue, and headache. If you stay in such an environment for an hour, emphysema will occur. , or even death.
Staying in an environment with severe ozone pollution for a long time may also damage skin health and may increase the risk of cancer.
Ozone pollution can also cause damage to the environment. For example, it will cause plant leaves to die and fall off, harm the ecological environment, and cause crop yield reduction.
Ozone introduction:
1. Ozone is a trace gas in the earth's atmosphere. It is caused by the oxygen molecules in the atmosphere being decomposed into oxygen atoms by solar radiation, and then the oxygen atoms interact with the surrounding It is formed by combining oxygen molecules and contains 3 oxygen atoms. More than 90% of the ozone in the atmosphere exists in the upper atmosphere or stratosphere, 10 to 50 kilometers above the ground. This is the atmospheric ozone layer that needs human protection. There are still a small number of ozone molecules lingering near the ground, which can still play a certain role in blocking ultraviolet rays.
2. Some experts have found that the concentration of ozone in the atmosphere near the ground has a tendency to increase rapidly, which is ominous. Although ozone plays an important role in protecting humans and the environment in the stratosphere, if its concentration in the troposphere increases, it will have harmful effects on human health. Ozone is irritating to the eyes and respiratory tract, and also affects lung function. Higher concentrations of ozone are also harmful to plants.
3. Judging from the properties of ozone, it can both help and harm people. It is not only a protective umbrella given by God to mankind, but sometimes it is like a powerful poison. So far, people have reached a complete understanding of the positive effects of ozone and what measures humans should take to protect the ozone layer and have done a lot of work. However, although people have already understood the negative effects of the ozone layer, there is no real and practical way to solve it except for atmospheric monitoring and air pollution forecasting.
