Beware of ozone bacterial infection at high temperature days, is it really?

□ There is no ozone bacteria, which is really ozone pollution. Ozone pollution will have a certain impact on people, but the impact is non -acute and requires a process.

□ In the face of ozone pollution, how can individuals protect it? The most direct way is to reduce outdoor activities during the high incidence and high concentration period of ozone and reduce the time exposed in the ozone pollution environment.

At present, high temperature weather in many places across the country is still continuing. There are rumors that this year's temperature is extremely sultry, ozone bacterial infections are intensified, and it is easy to cause a variety of diseases such as heart disease and respiratory diseases. Easy to be susceptible to be careful. What kind of bacteria are ozone bacteria? Are there really ozone bacteria infections?

"There is no ozone bacteria, which is really ozone pollution." Chen Jinsheng, a researcher at the Institute of Urban Environment of the Chinese Academy of Sciences, said that ozone pollution has been there for a long time, but its pollution is more hidden than PM_2.5. Ozone is not first -emitted pollutants, but a secondary pollutant.

An industry experts who have long been engaged in air pollution prevention also told reporters: "Ozone pollution is harmful to human health and plant ecology, but ozone is not bacteria. In fact, ozone has a bactericidal effect."

Chen Jinsheng said that there is a high concentration of ozone layer 10 kilometers to 35 kilometers from the ground, which prevents the solar short -wave ultraviolet radiation from entering the ground atmosphere and protecting the earth's ecosystem. But in the stream layer, higher ozone concentrations are not good for the earth's environment and human health.

Hu Min, a professor at the School of Environmental Sciences and Engineering of Peking University, introduced that unlike the sensory PM_2.5 pollution that is easy to be identified, ozone pollution is often hidden in the clear sky and is easily ignored by people. However, ozone pollution is not inferior to PM_2.5 pollution caused by ozone pollution to ecological environment and human health.

"The harm of ozone to the human body is mainly manifested by damage to the respiratory system, decreased vision, etc.; The harm to plants is to reduce the yield of crop; the harm to the material is that the fabrics, paper, etc. "Chen Jinsheng told reporters that ozone pollution will have a certain impact on people, but the impact is non -acute. It takes a process, including the concentration of ozone and the time exposed to ozone. Volkswagen does not have to over -interpret ozone pollution, let alone rumors such as ozone bacteria.

It is worth mentioning that in high temperature, it feels dull, hot, and not breathless. It is just that the temperature is too high and the wind speed is low, which is not caused by ozone pollution.

Relevant expert analysis pointed out that when the oxygen concentration of near the ground is low, it is basically harmless. In the change of ozone pollution concentration, the discharge of nitrogen oxides and volatile organic substances is the main cause. Strong ultraviolet radiation, high temperature, low humidity, and stable atmosphere are often conducive to the occurrence of optical pollution and the accumulation of ozone. Summer light conditions are good, ozone pollution is relatively easy to occur. The stronger the sunshine, the more intense the optical chemical reaction. At the same time, the actual ozone concentration also changes at any time. Generally, the concentration is the highest at 12 noon to two or three pm, and the night is lower. There are also large differences in oxygen concentration in different regions and seasons.

In recent years, ozone pollution in many cities in my country has frequently ended, endangering human health and ecological safety. The Ministry of Ecology and Environment has clearly stated that during the "14th Five -Year Plan" period, the focus of air pollution prevention in my country is the coordinated control of fine particles and ozone. The structural adjustment of industries, energy, transportation and other structural adjustments, and implementation of emission reduction projects will be comprehensively promoted to comprehensively promote the reduction of nitrogen oxides and volatile organic matter.

In the face of ozone pollution, how can individuals protect it? Experts say that the most direct way is to reduce outdoor activities in the ozone high incidence period and high concentration period and reduce the time exposed in the ozone pollution environment.
