When ozone reaches a certain concentration, it can make people breathe faster and feel chest tightness. If the concentration increases further, it can cause pulse acceleration, fatigue and headache. If you stay in this environment for 1 hour, emphysema will occur and even death will occur.
Staying in an environment with serious ozone pollution for a long time may also be harmful to skin health and may increase the risk of cancer.
Ozone pollution can also cause damage to the environment. For example, it will lead to the necrosis and shedding of plant leaves, endanger the ecological environment and reduce crop yield.
Introduction to ozone:
1. Ozone is a trace gas in the earth's atmosphere. It is composed of oxygen molecules in the atmosphere decomposed into oxygen atoms by solar radiation, and then the oxygen atoms are combined with the surrounding oxygen molecules, containing three oxygen atoms. More than 90% of ozone in the atmosphere exists in the upper atmosphere or stratosphere, which is 50 kilometers away from the ground 10 ~ 50. This is the atmospheric ozone layer that needs human protection. There are still a few ozone molecules hovering near the ground, which can still play a certain role in blocking ultraviolet rays.
Some experts have found that the ozone concentration in the near-surface atmosphere is increasing rapidly, which makes people feel bad. Although ozone plays an important role in protecting human beings and the environment in the stratosphere, if its concentration increases in the troposphere, it will have harmful effects on human health. Ozone can irritate eyes and respiratory tract, and also affect lung function. Higher concentrations of ozone are also harmful to plants.
From the nature of ozone, it can not only help people, but also harm people. It is not only an umbrella from heaven and human beings, but sometimes it is like a fierce poison. Up to now, people have a * * * understanding of the positive role of ozone and what measures humans should take to protect the ozone layer, and have done a lot of work. However, although people have known the negative effects of ozone layer, there is no really feasible way to solve these problems except atmospheric monitoring and air pollution prediction.
